The problem of poor bearing capacity often occurs in the operation of reducers. Based on the analysis of the working principle of the reducer, the factors that affect the bearing capacity of the reducer are as follows:
Firstly, the impact of the WPWDKV155, WPWDKV175, WPWDKV200, and WPWDKV250 reducers themselves
The manufacturing accuracy and operating speed of gears are internal factors that affect the load-bearing capacity of reducers. The ideal motion of a gear pair is a constant input and output speed. Due to errors in gear processing and assembly, the gears move relatively during the movement process, resulting in transmission errors and gear vibration, bringing internal additional loads to the meshing gears. At this point, the reducer will make a lot of noise and its load-bearing capacity will also decrease.
2、 The impact of prime movers and working machines
The prime mover and working machine are external factors that affect the load-bearing capacity of the reducer. Due to uneven loads, they can bring external additional loads to the gearbox. According to the different types of prime movers, the characteristics of working machinery can be divided into four types: uniform stability, slight impact, moderate impact, and severe impact. Generators, light elevators, and light centrifugal pumps with stable loads belong to the uniformly stable type. Heavy duty centrifugal pumps, multi cylinder piston pumps, etc. Belongs to a mild impact type; The lifting device and single cylinder piston pump belong to the medium impact type; Excavators and drilling rigs belong to severe impact types. The different types of prime movers and the different characteristics brought by working machinery are the main factors that affect the load-bearing capacity of reducers.
3、 The impact of connection on the reducer
The impact of connection on the reducer is mainly manifested in installation accuracy and connection method. The installation accuracy mainly refers to the coaxiality of the connection between the prime mover and the reducer. If the coaxiality is high, the additional load they bring to the pumping unit reducer will be small, and vice versa.
