Reducer bearing Failures and solutions
The gear reducer is one of the main equipment of the enterprise. Once the matching clearance occurs during the operation, it will cause severe damage to the transmission shaft and transmission gear, and cause major shutdown and shutdown accident, the enterprise will suffer huge economic loss. Once the bearing chamber of the reducer is worn out, the replacement cost of components is high, and the manufacturing cycle is relatively long. Generally, the repair method is disassembly and patching machine or reaming with steel sleeve, etc., which is time-consuming, laborious, and costly. The wear of the bearing chamber of the gear reducer is solved by using macromolecule composite material in western countries.
This kind of problem is difficult to be repaired and solved by repairing welding process. The welding quality of cast iron is not good, and it is easy to cause more serious secondary damage to parts when welding, and the replacement cost is high and takes a long time.
