When performing maintenance and upkeep on WPWEK155-250,WPWEDK40-70,WPWEDK50-80,WPWEDK60-100,WPWEDK70-120 hard gear reducers, the same problem is encountered: when does the bearing of the hard gear reducer need to be replaced? The editor of Dongchen Machinery summarized the relevant knowledge and content for reference.
1. When there is no oil in the hard tooth reducer, it is prohibited to drive it. Due to the qualified quality of lubricating oil, a very thin protective oil film will be formed at the contact points of rotating parts such as bearings during the operation of hard gear reducers, to prevent dry friction between hard and iron. If running without oil, it will damage the bearings, gears, gear shafts, and other transmission components.

When the hard tooth reducer is running and the bearing position is abnormally high, it is necessary to consider stopping the machine to check if the bearing is damaged. If there is any damage, it must be replaced immediately and cannot be operated with faults to avoid causing damage to other components and causing greater losses.
3. When the hard tooth reducer is running, the bearing position emits noise. It is necessary to stop the machine and check whether the bearing is damaged. If there is any damage, it must be replaced immediately. In this case, it is also necessary to consider whether the noise is caused by the bearing or the gear meshing.
4. It is recommended that after 7-8 years of normal operation, a major overhaul should be carried out to replace all bearings inside the hard tooth reducer, and at the same time, the transmission components such as gears should be inspected and overhauled.
