Maintenance method of reducer

In fact, the maintenance of the reducer is ignored by many users. If the reducer is not maintained for a long time, its life will be greatly reduced, and its performance will often be much worse than before. In order to make the reducer more durable, users are recommended to carry out regular maintenance of the reducer. Here are some methods for the maintenance of the reducer.


For the reducer used for the first time, the lubricating oil should be replaced after 300~600 hours of operation (about 7-14 days). After another three months of use, the reducer shall be replaced for the second time. After that, the lubricating oil shall be replaced every time the reducer works for 4000~6000 hours. The oil quality of the reducer shall be checked frequently. The oil containing impurities, pollution or decomposition must be replaced immediately.


Regular inspection and maintenance shall be carried out for the reducer, and necessary measures must be taken for scratches, gluing and significant wear; Always check the bolt tightness and oil quantity, and timely replenish oil when the oil level of the reducer is lower than the lower scale mark of the vernier; The surface of the reducer shall be clean, and the air vent shall not be blocked. During equipment operation, check whether there is abnormal vibration and whether the temperature meets the requirements.
