Master pointing, under the same load, that is, the axial force applied, in certain circumstances, the greater the contact angle of tapered roller bearings, the friction torque is greater or smaller?
Suppose the axial force is to the right, and if it is reversed, the friction on the right side of the bearing becomes larger, and the normal one is that the friction on the left becomes larger
The contact angle is large, the sliding friction between the roller end face and the retaining edge becomes smaller, and the contact angle is small, and the sliding friction between the roller end face and the baffle edge is mainly concentrated.
The greater the contact angle of a tapered roller bearing, the greater the axial load that can be sustained. When the axial force under certain circumstances, the larger the contact angle, the friction torque is small, this is because the rolling friction force than sliding friction is small.
