Tail failure is due to insufficient load, causing rolling element slippage in the bearing
Factors to consider during design:
►In order to achieve good bearing operation and avoid trailing phenomenon, all ball bearings and roller bearings must withstand a certain minimum load.
►If the minimum load requirement cannot be met, slippage may occur, which can cause overheating and noise. Hard lubricating grease can also cause this problem, especially in very cold environments.
measures:
►Additional external loads can be applied, such as installing external spring devices on the outer ring end face.
►You can also choose to use bearings with different internal clearances or different types of bearings.
►Reducing the size of bearings is also a solution.
Bearing adjustment leads to excessive preload
Factors to consider during installation:
►When adjusting the axial clearance or preload of the bearing, tightening the adjusting device (locking nut) too tightly can cause excessive preload force and high operating temperature.
►Excessive preload can also increase the friction torque inside the bearing. Example: There are tapered roller bearings or angular contact ball bearings at each end of the shaft.
measures:
►Confirm with the equipment manufacturer the correct installation steps for setting axial clearance or preload force.
►During and after the adjustment process, use a dial gauge to measure the axial displacement of the shaft.
