KOYO self-aligning roller bearing material performance using the impact on the fault

1. Diameter of axle and bearing friction compatibility when direct contact to prevent adhesion formation and boundary lubrication performance. Factors influencing the friction pair friction compatibility of the material is: ( 1) As a deputy to the difficulty of the composition of alloy materials metallurgy. ( 2) Materials and affinity of lubricant. ( 3) Become vice material in the absence of the friction factor of lubrication condition. ( 4) The microstructure of materials. ( 5) Thermal conductivity of materials. ( 6) The size of the material surface energy and the characteristics of the oxide film. 2. Embedding material allows foreign hard particles in the lubricant pliers and prevent scratches or ( And) The ability of abrasive wear. For metallic materials with low hardness and elastic modulus, embedding, and non-metallic materials are not necessarily, carbon graphite, for example, low elastic modulus, but the embedded sex is bad. Self-aligning roller bearing usually use soft material and hard material forming friction, usually made from soft material bearing shell. 3. In the diameter of axle and bearing bush of the running-in process, reduce the diameter of axle and bearing shell processing error, the alignment error and surface roughness parameter values, make contact even, thereby reducing the friction and wear rate. 4. Compliance of friction material on the surface of sliding friction surface initial elastic-plastic deformation compensation to match the performance of the poor and shaft deflection. Low modulus of elasticity of material compliance is good. 5. Abrasion resistance into vice material abrasion resistance. Under the condition of the rules of wear, wear rate or amount of wear, wear the reciprocal of abrasion resistance. Must be carried out on the bearing inspection and maintenance, inspection and maintenance to prevent failure is very important, in the work to review the rolling noise, vibration, temperature of bearing and lubricant. Although the bearing quality and so on various aspects are good, but the rolling bearing is precision components, its use should be measured accordingly. No matter how high performance bearing use, if use undeserved, will not get the desired performance. Attention about the use of the bearing has the following several: ( 1) And keep the bearing and the surrounding clean. Even the eyes can't see the little dust, will also bring bad influence to the bearing. So, to keep the surrounding clean the dust from invading spherical roller bearings. ( 2) , carefully use. In use for KOYO bearing strong impact, will produce scar and creasing, become the cause of the accident. Severe cases, can crack, fracture, so must pay attention to. ( 3) And use the appropriate operating tools. Avoid to existing tools to replace, must use the appropriate tools. ( 4) And to pay attention to the corrosion of the bearing. Operating KOYO bearing, hand sweat will become the cause of rust. Pay attention to the operation with clean hands, it is better to try to bring gloves.
