The conflict of the rolling bearing is mainly caused by the roll conflict and the sliding conflict between the rolling body and the ferrule raceway, and the sliding conflict between the cage and the rolling body and the ferrule guiding surface (the sliding conflict between the rolling bodies when there is no cage) ), the sliding conflict between the roller end face and the ferrule side face, the viscous resistance of the smoothing agent, the sliding conflict of the sealing device, etc.; the size depends on the type, scale, load, rotation speed, smoothness, sealing, etc. of the bearing Multiple elements.
In instruments and machinery that require low collision torque; deep groove ball bearings, cylindrical roller bearings and self-aligning ball bearings are generally used; to accept radial load, single row thrust ball bearings are used to receive bearing load; if combined load is accepted; Select the angular touch ball bearing; the load angle and the touch angle are all together; the minimum conflict torque can be obtained, if the distance between the two corners is too large; the centripetal and thrust bearing assembly methods can be used to deal with.
When selecting bearings with low conflict torque; the touch design should be prevented from using the touch seal equipment. Together; the smoothing method for bearings with low conflict torque; smooth drip, smooth oil mist and smooth oil and gas should be used.
