Analysis of Failure Causes of Rolling Bearings Caused by Skew
Bearing wear phenomenon caused by roller deflection: The reason for roller deflection is when the bearing load of the roller bearing is too low or seriously inclined, or the adjustment of the tapered roller bearing is improper. If the rib is not sufficient to absorb the skewing forces, the wear area occurs diagonally in the cage pockets due to the impermissibly high loads. This can lead to fracture of the beams of the cage and further damage to the sides, see Figure 90. Cause: Impermissible bearing tilt, partly due to misalignment Improper bearing clearance adjustment Remedy: Correct bearing adjustment Use self-aligning bearings to avoid misalignment. Cage damage 90: Diagonal wear of rolling bearing cage pockets compared to the traces). Cause: Excessive inclination of the bearing rings relative to each other, eg in ball bearings under combined load. So the balls have different circumferential velocities. High stress in the cage area, especially in the case of poor lubrication Remedy: Avoid tilting as much as possible It is best to use self-aligning bearings or bearings with nylon cage 91: Mutual tilting of the bearing rings results in There are high forces that cause the cage pocket walls to break.
