Bearing the exterior influence on bearing use when you don't know the things

Bearing - comfortable and durable Self-aligning roller bearing electricity department author for your explanation: bearing appearance effect on bearing use when you don't know what effect on the fatigue strength, bearing tiny peak valley of appearance, like many Angle, gaps and cracks, which is the origin of stress concentration. When bearing under the action of alternating load, due to the existence of stress concentration can reduce fatigue strength. Rough appearance, fatigue strength decreased. Bearing surface under the action of alternating stress, therefore, should be to reduce the roughness, especially bearing steel. Bearing on bearing appearance when using impact: effect on the corrosion resistance: spherical roller bearing appearance and air, water vapor and other corrosive substances, due to chemical and electrochemical effects, corrosion phenomena will happen. Bearing surface rough, because of the deep valley, corrosive substance accumulation, and reduces the corrosion resistance of the alloy. Especially its role in electrochemical. From the bottom of the gradual in-depth and expanded outline bearing corrosion, can lead to a sudden failure of the bearings. Bearing in severe corrosive environment, therefore, should have small surface roughness. Bearing on bearing appearance when using impact: on the influence of contact stiffness and positioning accuracy: when two rough surface contact, contact pressure, and the mountain, because of its small rough surface contact, bearing deformation (more easily Both elastic and plastic deformation) Thus reducing the contact stiffness and positioning accuracy. Therefore, in order to improve the contact stiffness, lower surface roughness. Bearing in addition to the above knowledge, the influence of surface roughness affects coordination performance, sealing and fluid friction resistance, etc. The influence of friction, wear, bearing appearance rough friction coefficient is larger. Relative motion appearance, frictional resistance is big, in addition to increased power consumption, make the bearing heating, deterioration of working conditions; Also due to the actual contact area of two small, surface contact pressure increase per unit area, increase the wear. At the same time, because looks rough, uneven appearance embedded, meshing is increased, can increase the wear and tear. If appearance is too smooth, however, two more attractive, on the surface of the storage, but also is advantageous to the lubricating oil, will increase the friction and wear. The roughness of the contact surface, therefore, should be appropriate. Bearing comfortable and durable, )
