    The Residential property As Well As Application Of Nanoparticles
    Nanopowder is additionally called nanoparticles, which usually refers to ultra-fine particles with a size between 1-100nm. Some individuals call it ultrafine particles. Its dimension is much more substantial than atom clusters and also smaller sized than normal particles. The form of the nanoparticles is spherical, plate, rod, horn, sponge, etc. The constituents of nanoparticles can be metals, oxides, or other various compounds.

    Characteristic of nanoparticles:
    1. Thermal attributes
    The melting point and sintering temperature of nanoparticles are much lower than that of traditional powders. This results from surface as well as user interface results. mos2


    As an example, the melting point of mass Pb is 600k, while 288k minimizes the melting point of 20nm spherical Pb particles, nano-Ag particles start to melt below 373k, as well as the melting point of traditional Ag is a lot higher than 1173k. Furthermore, the nano-TiO2 is obviously compressed when heated at 773k, as well as the very same densification of large-grain examples needs to be warmed up to 873k to accomplish this, which is significantly related to the sintering temperature.
    2. Optical characteristics
    Broadband strong absorption
    When the size is lowered to nanoparticles, it comes to be almost black, and the reflectance to noticeable light declines greatly.
    Some nanoparticles are like silicon nitride, SiC and also alumina have a broadband energised absorption range for infrared. As well as ZnO, ferric oxide, and titanium dioxide nanoparticles have a broadband energetic absorption spectrum for ultraviolet light.

    Blue and red shift
    Compared with bulk materials, nanoparticles generally have a blue shift in the absorption band, that is, the absorption band transfers to the short wavelength direction; as well as under specific problems, the absorption band shifts to the long-wave direction when the particle dimension is lowered to the nanometer degree, that is, red shift.

    3. Chemical properties
    Due to the surface impact, it can be utilized as a stimulant to enhance the response task.

    Application of nanoparticles:
    1. Nano coating
    Nano-coating uses surface area innovation to use component or every one of the nano-powder-containing product to the substratum. Because of the unique surface area homes of the nano powder, brand-new attributes are provided to the material.
    Nanoparticles can be made into surface area finishings to transform the optical residential properties of the material surface area, such as optical nonlinearity, light absorption, light representation, and light transmission. Nanoparticles have great applications in the light bulb industry. For high-pressure sodium lamps, 69% of the power of the iodine arc lamp is converted into infrared rays, as well as just a percentage of light power shows up light. The heating of the light will additionally minimize the life of the light.

    The nano-infrared layer has also been examined by many individuals. After the nano-powder of silicon dioxide, iron oxide and light weight aluminum oxide is worsened, it can highly soak up infrared rays, as well as can be made right into army garments. It can avoid the detection of enemy warm bands and reduce weight by 30%.

    2. Application in environmental protection
    The shortage of mineral power as well as environmental pollution have actually troubled people. The application of nanomaterials in environmental protection, environmental administration, as well as air pollution decrease has shown a successful scene. Nanoparticles can be anti-bacterial, anticorrosive, deodorant, detoxify the air, optimize the setting, and also promote destruction. Additionally, they can also absorb heavy metal ions to detoxify water, adsorb germs, infections, and hazardous ions.

    3. Photocatalysis of nanoparticles
    Photocatalysis can be utilized for environmental protection, destruction of chemicals, raw material, etc. Because of the tiny fragment diameter, large particular surface, and high photocatalytic efficiency; besides, most of the electrons and holes generated by the nanoparticles will certainly not recombine when they get to the surface, so the holes are reduced, and also the chemical reaction task is high.

    The iron nanoparticles, nickel nanoparticles, copper nanoparticles, titanium nanoparticles, etc., produced by Luoyang Tongrun Nano Modern Technology Co., Ltd has the outstanding efficiency as a result of its high purity, consistent particle dimension distribution, easy to spread use. These nanoparticles can be widely used in lubricating, ceramics, wear-resistant, photoelectric, and so on industries.

    Inspection and Maintenance of INA Needle Bearing
    INA needle bearing is a roller bearing with a cylindrical roller. The roller is thin and long relative to its diameter. This roller is called a needle roller. Although it has a small cross-section, the bearing still has a high load-bearing capacity, so it is especially suitable for the situation where the radial space is limited. Of course, with the popularization of this kind of bearing, how to detect and maintain it has become a big problem.

      Six techniques for detecting INA needle Bearing

    1. Oil film resistance diagnosis technology

    Features: the same evaluation standard can be used for different working conditions. The results of the diagnosis of surface peeling, indentation, and crack are poor.

    Application scope: it is suitable for the occasion where the rotating shaft is exposed.

     

    2. Vibration diagnosis technology

    Features: vibration diagnosis technology is widely used; online monitoring can be realized; diagnosis is fast, and diagnosis theory is mature.

    Application: it is especially suitable for the fault monitoring of INA Bearing in rotating machinery.

     

    3. Ferrography diagnosis technology

    Features: the machines do not need to be disassembled; the investment is low, and the effect is excellent; the early fatigue failure of needle roller bearing can be found; the wear mechanism can be studied.

    Application scope: it is suitable for the fault diagnosis of INA Bearing Lubricated with lubricating oil, and it isn't very easy for bearing lubricated with grease.

     

    4. Temperature Diagnosis Technology

    Features: the diagnosis is simple, and the effect of the judgment is sound.

    Scope of application: it is suitable for a simple routine diagnosis of needle bearing in the machine.

     

    5. Optical fiber monitoring and diagnosis technology

    Features: high sensitivity of optical fiber displacement sensor; direct extraction of signal from ina bearing surface to upgrade the signal-to-noise ratio; it can directly reflect the manufacturing quality, surface wear, load, lubrication, and clearance of the bearing.

    Application scope: suitable for the machine that can install the sensor in the bearing seat.

     

    6. Acoustic emission diagnosis technology

    Features: rapid and simple diagnosis, on-line monitoring.

    Application scope: the new technology developed in recent years is seldom used in the condition monitoring of needle bearing.

    Maintenance of INA needle bearing

    To give full play to the needle bearing and maintain its proper performance for a long time, it is necessary to do an excellent job in regular maintenance (regular inspection). It is essential for improving productivity and the economy to find faults early and prevent accidents in advance through proper routine control.

       1. Cleaning

    When removing the ina bearing for inspection, first, we need to make appearance records through photography and other means. Moreover, confirm the amount of residual lubricant and sample the oil before cleaning the bearing.

    a. Bearing cleaning is divided into excellent cleaning and rough cleaning. If the bearing is revolved in the oil, please pay attention to damage to the rolling surface because of foreign matters.

    b. During excellent washing, slowly rotate the bearing in the oil and proceed. 

    After cleaning, apply antirust oil on the needle bearing immediately.

       2. Inspection and judgment

    To judge whether the removed ina bearing can be reused, it is important to check its dimensional accuracy, rotation accuracy, sealing ring, raceway surface, cage, internal clearance, and mating surface.

    The inspection results can be judged by those who use inertia bearing or are proficient in bearing.

    The criteria of judgment vary according to the mechanical properties and importance, as well as the inspection period, etc. In case of the resulting damage, the needle bearing shall not be reused and must be replaced.

    1) Fracture and defect of INA Bearing parts.

    2) Peeling of the rolling surface of the raceway surface.

    Of course, the loss of bearings is a very healthy thing. What we need to do is to extend their service life as much as possible in daily use. Therefore, it is suggested that when using the bearing, attention should be paid to the installation, lubrication, clearance, and other links, to ensure the work progress and reduce the production cost.

    SKF 16015 * bearing


    After the SKF bearing is installed, in order to check whether the installation is correct, it is necessary to perform a running check. Small machines can be rotated by hand to confirm whether they rotate smoothly. The inspection items include poor operation due to foreign objects, scars, and indentations, unstable torque due to poor installation and poor processing of the mounting seat, excessive torque due to too small clearance, installation error, and seal friction, etc. Wait. If there is no abnormality, power operation can be started.

    Large-scale machinery cannot be rotated manually, so immediately cut off the power after starting without load, and the machinery is idling. Check for vibration, noise, and contact with rotating parts. After confirming that there is no abnormality, enter the power operation.

    The power operation starts at a low speed with no load and slowly increases to the rated operation under the specified conditions. The items to be checked during the test run are whether there are abnormal sounds, changes in SKF bearing temperature, leakage or discoloration of lubricants, etc. If an abnormality is found, the operation should be stopped immediately, the machine should be inspected, and the bearing should be removed for inspection if necessary.

    SKF bearing temperature can generally be estimated based on the external temperature of the bearing seat. However, it is more accurate to use the oil hole to directly measure the temperature of the outer ring of the bearing. The temperature of the bearing gradually increases from the start of operation, and usually stabilizes after 1 to 2 hours. If the bearing is installed improperly, the temperature will rise sharply, resulting in abnormally high temperature. The reasons include too much lubricant, too small bearing clearance, poor installation, and too much friction in the sealing device. In the case of high-speed rotation, the wrong choice of SKF bearing structure and lubrication method is also the reason.

    The Basic Elements Of Purchasing INA Bearings

    When designing a new spindle, before selecting an INA bearing, first consider the spindle performance parameters, roughly determine the most critical performance, and then enter further exploration. (Including: spindle speed, spindle accuracy, spindle rigidity, spindle life, spindle heat, spindle reliability) After the spindle parameters are determined, the actual dimensions of the spindle (shaft diameter, length, bearing span) are determined. 

    According to the bearing type (ball or cylindrical roller bearing), arrangement (column number), drive mode (transmission belt, gear, motor, built-in motor), lubrication (grease, oil and gas, oil mist, spray) and other spindle parameter settings Its structure.

    Bearing radial load

    The INA bearings that mainly bear radial loads are radial bearings. The nominal contact angle of this type of bearing a0 <= 450. Roller bearings with the same ruler can bear larger radial loads than ball bearings.

    N-type and NU-type cylindrical roller bearings can only bear radial loads, and other types of radial bearings can bear both radial loads and axial loads.

    Bearing axial load

    The bearings that mainly bear axial loads are generally thrust bearings, whose nominal contact angle a0> 450. Thrust bearings and thrust angular contact ball bearings can withstand axial forces in one or two directions at the same time, depending on the structure. When the bearing force is particularly high, thrust cylindrical roller bearings and thrust spherical roller bearings are preferred.Thrust spherical roller bearings and one-way thrust angular contact ball bearings can withstand both axial and radial loads, and other thrust bearings can only withstand axial loads.

    Bearing length compensation

    Supporting a shaft and a bearing usually adopts a structure in which a fixed bearing and a floating bearing are combined. Traveling INA bearings compensate for shaft length errors and thermal expansion.NU type and N type cylindrical roller bearings are ideal free bearings. These bearings can compensate for their own length. The inner and outer rings of the bearing can be tightly fitted.

    Length compensation for sliding fit

    Non-separable bearings can also be used as swimming bearings. One of the two rings of this type of bearing adopts a fit, and there is no axial fixed surface. Therefore, a ring of the bearing can move on its bearing surface.After determining the size and type of precision bearings, consider the specific design of the bearings.

    Fully consider the bearing fatigue life, rigidity, heat and other factors, select the most appropriate bearing clearance (preload).After determining the design of the main shaft structure, the necessary conditions for actual installation should be considered.

    High-precision bearing installation shaft and bearing seat accuracy, tolerance fit, tightening force of set nut required for installation and fixing, INA bearing preload after actual installation and confirmation of internal clearance.INA bearings are precision fittings, and need to be handled according to the correct method during installation and use in order to extend the service life of INA bearings. ERIC BEARING LTD have rich stock for INA NUTR50-A,  pls click here : 


    The surface of the INA bearing is coated with anti-rust oil. You must carefully clean it with clean gasoline or kerosene, and then apply clean high-quality or high-speed high-temperature lubricating grease before installation and use. The effect of cleanliness on the life of miniature bearings and vibration noise is very large. But we have to remind you in particular that the fully enclosed bearings do not need to be cleaned and refueled.

    When lubricating INA bearings, the more grease is applied, the better. This is a common misconception. 

    The correct installation of INA bearings also affects the accuracy, life, and performance of the bearings. Therefore, the design and assembly department should fully study the installation of INA bearings. Hope to install according to the operation standard. The work standard items are usually as follows:

    (1) Cleaning bearings and bearing related parts

    (2) Check the dimensions and finishing of related parts

    (3) Installation

    (4) Inspection after installing the bearing

    (5) Supply lubricant

                                    Selection, Maintenance And Overhaul Of NSK Bearings

    1.Selection of NSK bearings
    At present, various mechanical equipment, instruments and other markets have increasingly strict requirements on the performance and quality of NSK bearings, and the working environment of bearings has become more and more diverse.  it is necessary to analyze and study from multiple angles. When selecting a bearing, generally consider the ease of installation, arrangement, and disassembly of the bearing as a shafting, the size of the bearing, the allowable space, and the marketability of the bearing, etc., and first determine the bearing structure. Second, determine the size of the bearing to be selected while comparing the mechanical design life of the equipment using the bearing and the durability limit of various NSK bearings. In addition to considering the fatigue life of the bearing, we should also thoroughly consider the grease life, wear, noise and other factors related to the aging of the grease when selecting the bearing. According to the different uses of the bearing, the bearing clearance, accuracy, cage structure, and fat should also be made corresponding requirements, and the bearing can be specially designed when necessary. There is no specific order and rules for selecting bearings, and relevant conditions such as the conditions and performance of the required bearings should be considered according to the actual situation.

    2. NSK bearing maintenance
    During the use of NSK bearings, to ensure the proper use, performance and life of the bearings, it is necessary to perform necessary maintenance on the bearings to ensure the stability and reliability of NSK bearings, improve work efficiency and reduce work costs. The support of the bearings needs to be performed regularly. The operating status of the bearings is monitored according to the prescribed standards, including the bearing's rotation factor, vibration, temperature, etc., and the lubricants are regularly replenished or replaced, and systematically disassembled and inspected.

    3. Maintenance of NSK bearings
    After removing the bearing, the first record the appearance of the bearing to be inspected, confirm the remaining amount of lubricant and sample the oil for inspection, and clean the bearing. Bearing cleaning is divided into coarse cleaning and excellent cleaning. Put the bottom of the metal mesh in the container first to avoid the bearings directly contacting the dirt in the box. To prevent damage to the rolling surface of the bearing during rough cleaning, be careful not to rotate the bearing with soil. Use a brush to remove the grease and stickies from the bearings in the coarse cleaning oil, and then clean them carefully. Let the bearings be cleaned while rotating in clean, clear oil.

    After the bearing is cleaned, check the state of the raceway surface, rolling surface, mating surface of the NSK bearing, the increase of bearing clearance, the wear of the cage, and any damage that affects the reduction of dimensional accuracy to determine whether the bearing is working correctly. Non-separable NSK bearings can first keep the inner ring of the bearing horizontal, and rotate the outer ring to see if the bearing runs smoothly. For separate bearings such as tapered roller bearings, the rolling elements and the raceway surface of the outer ring can be inspected separately.

    Examples of bearing damage, such as seizing of spherical roller taking rings, have various reasons: for example, insufficient lubricant, improper, imperfect oil supply and drainage structure, foreign matter mixed in, incorrect bearing installation, and large shaft deflection and many more. Therefore, it is sometimes difficult to find out the cause by merely investigating bearing damage. However, as long as you understand the main engine using the bearing, the user requirements, the bearing peripheral structure, and the situation before and after the accident, you can comprehensively analyze the bearing damage and many reasons to prevent similar accidents from happening again.

    Roller Bearings 2020.05.28 17:07

    Roller bearing is a kind of rolling element bearings that carries loads by placing a number of rolling elements. The rolling elements between the two rings are called races. The races causing much less frictions than sliding elements.

    滚动元件旋转轴承在更大的孔中使用轴,称为“滚子”的圆柱体紧密填满轴和孔之间的空间。在上述示例中,随着轴的旋转,每个辊子都充当原木。但是,由于轴承是圆形的,因此滚子永远不会从负载下掉落。 

    与球轴承不同,滚子轴承可以承受很大的载荷。滚动体可以设计得更大一些,以保持高负荷。

    因此,滚动轴承的形状和尺寸范围很广,可以针对特殊情况进行定制。同样,使用法兰,保持架和多列轴承可以提高性能,以满足特定的应用需求。

     

    火花轴承  (又名,无锡火花轴承有限公司有限公司)是在生产高品质的球轴承和一个专业的轴承提供商拥有超过10年的经验滚子轴承  具有大类别,包括球面滚子轴承,圆柱滚子轴承,圆锥滚子轴承,深沟球轴承,调心球轴承,角接触球轴承和推力球轴承。

    The correct installation of TIMKEN bearings affects accuracy, life and performance. Therefore, the design and assembly department should fully study the bearing installation. Hope to install according to the operation standard.

    The work standard items are usually as follows:

    Check the size and finishing of related parts;

    Installation;

    Supply lubricants;

    Cleaning TIMKEN bearings and TIMKEN bearing related parts;

    Inspection after installing TIMKEN bearing;

    The TIMKEN bearing packaging was opened just before installation. Lubricating oil is not necessary to be cleaned, but TIMKEN bearings for instruments or high-speed bearings should be cleaned with clean oil to remove the anti-rust agent applied to TIMKEN bearings. General grease is lubricated and filled with grease directly without cleaning. Furthermore, bearings that have been sealed with grease are used without cleaning. The TIMKEN bearing with the anti-rust agent removed is easy to rust, so it can not be left unattended.

    KOYO Bearing

    A shaft often requires two fulcrums, that is, two sets of rolling bearings for support. The bearing configuration just solves the problem of how the bearing on the fulcrum fixes the shaft system axially, and how to avoid the bearing from jamming after thermal expansion. Based on the understanding of bearing knowledge, Eric Bearing Limited shares the typical knowledge of bearing configuration and hopes to help everyone.

    Before we configure, we must understand some points related to bearings: The expansion and contraction of the shaft caused by temperature changes.

    Bearings are easy to install and disassemble. The tilt of the inner and outer rings due to shaft deflection and installation errors.

    The method of reading and preloading of the entire rotating system including bearings. Bear and transfer loads at the most suitable location.

    INA bearing selection summary
    The market requirements of various mechanical devices and instruments that use rolling bearings are becoming stricter, and the requirements and performance of bearings are also becoming more diversified. In order to select the most suitable bearing from the numerous structures and sizes, it is necessary to study from various angles.
     
    When selecting an INA bearing, the bearing arrangement, ease of installation, and disassembly as a shafting, the space allowed by the bearing, the size, and the marketability of the bearing are generally considered, which roughly determines the bearing structure. Secondly, while comparing the design life of various machines using bearings and the various endurance limits of the bearings, the bearing dimensions are determined. When choosing an INA bearing, it is often biased to consider only the fatigue life of the bearing, and the grease life, wear, and noise caused by grease aging also need to be fully studied. Furthermore, according to different applications, it is necessary to select the bearings with special requirements for accuracy, clearance, cage structure, grease, etc. However, there is no certain order and rules for selecting INA bearings. The priority should be the conditions, performance, and most related matters that are required for the bearings, which is especially practical.
     
    Influence of external conditions on INA bearings
    Vibration can be said to be quite sensitive to damage to INA bearings, and flaking, indentation, rust, cracks, wear, etc. will be reflected in the INA bearing vibration measurement. Therefore, the size of the vibration can be measured by using a special bearing vibration measuring device (frequency analyzer, etc.), and the specific circumstances of the abnormality cannot be inferred by the frequency division. The measured value differs depending on the use condition of the bearing or the installation position of the sensor, etc. Therefore, it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.
     
    High temperature is also harmful to the lubricant of INA bearings. Sometimes INA bearing overheating can be attributed to INA bearing lubricant. Long-term continuous rotation of bearings at temperatures exceeding 125 ° C will reduce bearing life. The causes of INA high temperature bearings include: insufficient lubrication or excessive lubrication, lubricants. It contains impurities, excessive load, INA bearing damage ring, insufficient clearance, high friction caused by oil seal and so on.

    To fulfill market-specific needs, some bearings can have no internal ring or external ring or with a dust-proof, seal ring, and various other frameworks. Typical products: The products of rolling elements and internal and also outer rings need high hardness and get in touch with tiredness stamina, superb abrasion resistance, as well as impact strength. Generally made from chromium-containing alloy steel, frequently used materials are GCr15, GCr15SiMn, GCr6, GCr9, etc., and the hardness can reach HRC61-65 after warmth therapy. Cages are generally marked from low-carbon steel plates, and also high-speed bearings are mainly made of non-ferrous steel or plastic units.
