High temperature bearing lubrication purpose and what is the relationship between service life

High temperature bearing lubrication purpose and what is the relationship between the service life of the bearing of life simply divided into fatigue life, using life, wear and tear, A fundamental types of component failure) Life, wrong with life. 1. Using life: is the above three refers to sexual life, in theory, it refers to the bearing fatigue life, under normal use conditions characterized by bearing wear life, in the condition of abnormal, make no defect, on behalf of wrong with life. 2. Fatigue life: bearing main moving part of materials to the limit, formation of bearing failure before the total time. Dynamic load rating: when life expectancy of 10000 RPM, load bearing can accept. Such as cross section thin-walled bearing done extremely thin cross section of the bearing, also finished product miniaturization, lightweight. Extended its scope of use of a variety of products. Its general divided into glue sealing - RS, iron seal - ZZ, plane, canvas - K, copper - M。 Equivalent dynamic load: refers to the practice of the bearing load according to the operation condition of dynamic load stop conversion for certain the assumption of the load. 3. Wrong with life: bearing fault, before work is lost to the cumulative working hours. Thin wall bearing manufacturer for bearing low friction torque, high rigidity, good rotation accuracy, using small diameter of steel ball. The use of hollow shaft, ensure the lightweight and wiring of the space. Thin wall type high temperature bearing done extremely thin cross section of the bearing, also finished product miniaturization, lightweight. Extended its scope of use of a variety of products. 4. Wear and tear, A fundamental types of component failure) Life: bearing due to normal wear and tear, clearance increases to rules limit cumulative working hours before. In terms of degree of the bearing industry today, should wear life & gt; Fatigue life, but in practice traction motor is just the opposite. Bearing the purpose of smooth: 1. Longer fatigue life. Rolling bearing fatigue life, in the rotation, smooth rolling contact surface is good, is extended. This is the greatest benefit of smooth bearing, it can increase the fatigue life, extend the life of the bearing. 2. Reduce friction and friction losses. In a bearing ( 轴承) Ring, rolling body and stick to each other contact local and avoid contact with metal, reduce friction and wear. 3. Discharge frictional heat and cooling cycle to oil to oil discharge by the heat of friction attack, or coming from external heat, cooling. Avoid ( Bearing temperature, smooth the oil itself. 4. Other colleagues smooth bearing can also have internal check foreign body into bearing, or avoid bearing rust, corrosion, Definition: refers to the decadent, dies, corrosion, etc. ) The effect of. In an article: high temperature bearing under the early damage is the reason why an article: assume that high temperature bearing grease metamorphism is what look like
