The problem of poor payload often occurs during operation of helical gear reducers. According to the analysis to the working principle of the reducer, the following three factors affect the payload of the reducer.
1. The influence of the helical gear reducer itself
Gear manufacturing accuracy and running speed are internal factors that affect the payload capacity of the reducer. The ideal movement of the gear pair is that the input and output speeds are constant. Due to gear processing and assembly tolerance, the gears produce relative movement during the motion, resulting in transmission tolerance and gear vibrations, which bring internal additions payload to the toothed gears. At this time, the reducer will produce lots of noise and the payload capacity will also decrease.
2. The influence of prime mover and working machine
The prime mover and working machine are external factors that affect the payload capacity of the reducer. Due to the unevenness of the load, they will bring additional external loads to the reducer. According to the different types of prime movers, the characteristics of the working machine can be divided into four types: uniform and stable, light impact, medium impact, and severe impact. Generators, light lifts, and light centrifugal pumps with stable loads are of uniform and stable type; heavy-duty centrifugal pumps and multi-cylinder piston pumps are of light impact type; lifting devices and single-cylinder piston pumps are of medium impact type; excavators, drilling rigs are of severe impact type. The different types of these prime movers and the different characteristics of the working machine are the primary factors affecting the payload capacity of the reducer.
3. The influence of connection on helical gear reducer
The influence of the connection on the helical gear reducer is mainly manifested in the installation accuracy and connection method. The installation accuracy mainly refers to the coaxiality of the prime mover when connected with the reducer. If the coaxiality is high, the additional payload they bring to the pumping unit reducer will be small, and vice versa.
