Basis for replacement of reducer bearings!

I believe that you will encounter the basis of the reducer bearing replacement when doing the maintenance and maintenance of the reducer. Here is a brief introduction to the problems that need attention in this regard.

When do the bearings of the reducer need to be replaced? Siemens Flanders reducer bearings generally use imported bearings, brands such as SKF, FAG, etc., such bearings have a long service life, and they can be used for a long time under the condition of proper maintenance and regular replacement of imported lubricants that meet the requirements. time. However, the actual use of the reducer varies greatly in industry and mining, and cannot be generalized. In the site where the industry and mining are bad and the maintenance is not in place, the bearing damage of the reducer also happens from time to time gear unit!

1. It is prohibited to drive when there is no oil in the reducer!
Due to the qualified lubricating oil, during the operation of the reducer, an extremely thin protective oil film will be formed at the contact position of the bearing and other rotating parts to prevent the dry friction of hard to hard and iron to iron. If it is operated without oil, it will damage the transmission components such as bearings, gears and pinions!

2. When the reducer is running and the bearing position is abnormally high, consider stopping the machine to check whether the bearing is damaged. If it is damaged, it must be replaced immediately. It can not run with disease, causing damage to other parts and causing greater losses.

3. When the reducer is running and the bearing position makes noise, consider stopping the machine to check whether the bearing is damaged. If it is damaged, it must be replaced immediately. In this case, also pay attention to consider whether the noise is caused by the bearing, or it may be the sound of gear meshing. This situation is more complicated and requires multiple factors to judge.

4. Siemens Flanders reducer adopts imported bearings such as SKF, FAG, so it has a long service life, but we recommend that after 7-8 years of normal operation, an overhaul should be done to replace all the bearings in the reducer, and at the same time Check and overhaul gears and other transmission parts.
