Preload Methods for Rolling Bearings
The preload methods of rolling bearings are divided into two categories: radial preload method and axial preload method. The radial preload method is also called radial top tightening method, which is mostly used in tapered bore bearings that bear radial loads; the axial preload method is also called axial preload method, which is divided into two types: positioning preload and constant pressure preload: in positioning preload, the appropriate preload amount can be obtained by adjusting the size of the bushing or gasket, and the appropriate preload can also be adjusted by measuring or controlling the starting friction torque; constant pressure preload is a method of using spiral springs, disc springs, etc. to obtain appropriate preload of the bearing. Proper preload of rolling bearings is the key to balancing torque, load distribution and service life.
