The working principle of the bevel gear reducer is "prime mover - connection - bevel gear reducer - connection - working machine" that is the bevel gear reducer through the connection device to transfer the power of the prime mover to the work machine.

In the operation of the bevel gear reducer, there is often a problem that the carrying capacity is poor. According to the analysis of the working principle of the bevel gear reducer, we can summarize the factors that affect the carrying capacity of the bevel gear reducer into the following three points.

1, the impact of the original motivation and work machine
 
The prime mover and the working machine are external factors that affect the carrying capacity of the bevel gear reducer, and they give an external additional load to the bevel gear reducer due to the load nonuniformity. According to the different types of motives, the characteristics of the machine can be divided into uniform and smooth, slight impact, moderate impact, severe impact of four. Heavy-duty centrifugal pump, multi-cylinder piston pump, etc. are a slight impact type; lifting device, single-cylinder piston pump is a medium impact type; excavator, drilling machine Is a serious impact type. The different types of these prime mover and the different characteristics of the work machine are the primary factors influencing the carrying capacity of the bevel gear reducer.
 
2, the impact of gear reducer itself
 
The manufacturing accuracy and running speed of the gears are the internal factors that affect the carrying capacity of the spiral bevel gear reducer. The ideal motion of the gear pair is the constant value of the input and output speeds. Due to the presence of gear machining and assembly errors, the gears produce relative motion during the movement, resulting in transmission errors and gear vibrations, which bring internal additions to the gears Load, then the spiral bevel gear reducer will produce a larger noise, while carrying capacity will decline.
 
3, the impact of the connection on the spiral bevel gear reducer
 
The effect of connecting to the bevel gear reducer is mainly manifested in the installation accuracy and connection mode. The installation accuracy mainly refers to the coaxiality of the prime mover when connected with the bevel gear reducer. If the coaxiality is high, the additional load to the gear reducer is small and vice versa.
