Reducer bearing failure and treatment

The reducer bearing is one of the important components in the reducer and bears the transmission force and load. Bearing failure will prevent the smooth operation of the reducer and may lead to more serious mechanical failure. Therefore, it is very important to correctly handle reducer bearing failures.

1. Common causes of reducer bearing failures:

1. Poor bearing lubrication: Bearings need sufficient lubricating oil film to reduce friction and wear. If lubrication is poor, friction will increase and the bearing will easily fail.

2. Bearing overload: When the load of the reducer exceeds the rated load capacity of the bearing, the bearing may suffer from wear, breakage and other failures.

3. Environmental pollution: Pollutants in the working environment of the reducer, such as dust, moisture, etc., may enter the inside of the bearing and cause bearing failure.

4. Improper installation: If the fit, non-parallelism, etc. of the bearing and the shaft are not correctly adjusted during installation, the bearing will run unevenly and cause failure.

5. Bearing material and quality issues: The quality and material of the bearing determine its service life. If there are problems with the material or quality of the bearing itself, it may easily cause failure.

2. How to deal with reducer bearing failure:

1. Check the lubricating oil: Regularly check the quality and quantity of the reducer lubricating oil to ensure that the grease is clean, and replace and replenish the lubricating oil in a timely manner.

2. Prevent overload: According to the design requirements and usage conditions of the reducer, select the appropriate model and bearing with rated load capacity to avoid overload use.

3. Strengthen environmental protection: During the use of the reducer, try to keep the working environment dry and clean to prevent dust, moisture and other pollutants from entering the inside of the reducer.

4. Correct installation: When installing the reducer, it is necessary to carefully adjust the fit, non-parallelism, etc. of the bearing and shaft to ensure that it is installed correctly and avoid unstable operation.

5. Choose high-quality bearings: When selecting bearings, choosing bearings with good quality and materials can extend the service life of the bearing and reduce the possibility of failure.

In addition to the above common treatment methods, regular maintenance of the reducer is also required, such as regularly checking the wear of the bearings and replacing worn bearings in time; regularly cleaning the inside of the reducer to avoid the accumulation of dust and dirt, etc. At the same time, for reducers that have been used for a long time, the lubricating oil should be replaced and cleaned regularly.

In short, the treatment of reducer bearing failures requires comprehensive consideration of factors such as lubricating grease, overload, environmental pollution, installation quality, and bearing materials. Through reasonable treatment methods and regular maintenance, the service life of the reducer bearings can be maximized and the deceleration ensured. normal operation of the machine.
