Gear oil pumps are mainly used for oil medium transmission, pressurization, fuel injection, etc. in petroleum, chemical, metallurgical, mining, power stations and other industries, as well as thin oil circulation in large mechanical equipment, and can be used as lubrication pumps in various mechanical equipment use. Motor overheating is a common problem in the working process of gear oil pumps. The specific analysis and testing are as follows.

Common gear reducer motors are mainly four series of reducer products: R series coaxial gear reducer, S series worm gear reducer, K series spiral bevel gear reducer, F series parallel shaft helical gear reducer, although these 4 The gear forms and angles of the large series of gear reducer motors are different, but they all have the following four characteristics.

1. Tip relief of gear (1) Crown part modification (general): It is to cut the crown part into a slightly convex shape than the correct involute by a special processing method, so when the tooth surface is affected When the transmission force is deformed, it will alleviate the interference that may be caused to the mutually biting gears, and can reduce the noise during biting and prolong the life. The effect is remarkable.

Couplings can be divided into three categories: rigid couplings, flexible couplings and safety couplings. Each category can have several varieties, such as rigid couplings and flange couplings, sleeve couplings, etc. Rigid couplings can only be used to connect two strictly coaxial shafts. The flexible coupling, due to the special design of the structure, has many functions.
