What issues lead to overheating of spherical roller bearing materials?
Clicks:9353 Date:10-31
Here are some explanations for why the spherical roller bearing material is high in temperature:
1, friction compatibility
The direct contact between the shaft and the spherical roller bearing prevents adhesion and formation of boundary lubrication. The influence of friction is the compatibility of materials, which is the degree of difficulty in the formation of alloy by metallurgical alloying, the compatibility of materials and lubricating oil, the friction coefficient of the auxiliary materials in the absence of lubrication, and the thermal conductivity of materials.
2, running in
The running process of axis and spherical roller bearing in diameter, reducing the diameter of the shaft and the spherical roller bearing machining error, concentricity error, surface roughness, the uniform contact, thereby reducing the friction and wear properties.
3, corrosion resistance
Corrosion resistance of materials. The use of lubricating oil will be gradually oxidized in the atmosphere, produce acidic substances, and in most oil also contains extreme pressure additives, they will weaken spherical roller bearing material, therefore, the corrosion resistance of spherical roller bearing materials.
4, Embeddedness
Make the lubricant clamp on foreign particles and prevent scratch or (or) abrasive wear. Metal materials, low hardness and lower elastic modulus, and embedded, while metal materials are not necessarily, such as carbon graphite, low elastic modulus, but embedded is not good. Spherical roller bearing is usually made of soft materials and hard materials to form friction plates, generally using soft material spherical roller bearing.
5. Compressive strength
Spherical roller bearing is the ability not to be crushed or not changed under the load
