Gear reducer common faults and solutions

Gear reducers are commonly used in a variety of mechanical equipment, and have been widely used in many industries. In actual production, some gear reducers may have abnormal malfunctions such as noise, wear and oil leakage. How to solve these faults?

In the long-term operation of the gear reducer, there are often faults such as wear and leakage. The most important ones are:
1. The bearing chamber of the gear reducer wears, which in turn includes the wear of the bearing housing, the bearing housing of the housing, and the bearing housing of the transmission.
2. The shaft diameter of the gear reducer is worn, and the main wear parts are in the shaft head and keyway.
3. The bearing position of the gear reducer drive shaft wears.
4. The gear reducer joint surface leaks.
 For the wear problem of the gear reducer, the traditional solution of the enterprise is repairing after repair welding or brush plating, but both have certain drawbacks. For example, the thermal stress generated by the repair welding high temperature cannot be completely eliminated, which may cause damage to the material, resulting in bending or breaking of the gear reducer components.

Brush plating is limited by the thickness of the coating, and it is easy to peel off. The above two methods use metal to repair the metal, which can not change the "hard to hard" coordination relationship. Under the combined action of each force, it will still cause re-wear. Therefore, pay attention to the following items when using and maintaining the gear reducer.
1. The gear reducer adopts 460# medium load industrial gear oil, and the working environment temperature is 0~40°C.
2. After using the gear reducer for the first time for 100 hours, the inner cavity should be cleaned and replaced with new gear oil, and the oil should be changed every 2000 hours.
3. When disassembling the gear reducer, try to avoid hammering to avoid damage to normal parts.
4. If it is found that there is oil leakage in the shaft extension or joint of the gear reducer during use, the seals such as the skeleton oil seal should be replaced in time.

In short, most of the common faults of gear reducers are related to daily improper operation and maintenance. Therefore, in order to reduce the occurrence of gear reducer failures, in addition to purchasing high-quality products, it is also necessary to use them reasonably, and it is necessary to periodically perform gear reducers. Overhaul, cleaning and lubrication.
