What causes the gear unit bearing to fail？

After a long period of use, some equipment will encounter some problems. Generally, the bearings of speed reducers can be used until the working surface of the bearings peels off due to fatigue under normal installation and lubrication maintenance conditions. Many people do not know what causes the failure of speed reducer bearings. Let's take a look below.

1. Analysis and calculation of operating state parameters of the reducer bearing, such as load, rotational speed, and relevant data of the original bearing.

2. The measurement of the geometric tolerance of the mounting position of the reducer bearing, the analysis of the fit of the bearing with the journal and shaft housing, the investigation of the installation fit and use of the bearing seat, and the correctness of the method for installing and disassembling the bearing.

3. Abnormal phenomena before gear unit bearing damage, such as vibration, noise, temperature rise, changes in motor current, and changes in external load, etc.

In actual use, rolling bearings are often scrapped due to premature damage. The premature damage of gear reducer accessories can result from manufacturing defects in bearings and poor bearing materials, but more often from the use, improper maintenance, and poor lubrication of gear reducer accessories.
