There are also low gear and middle gear, high speed gear, whose diameter is big. Whose little one??????????
The shaft diameter of the low speed shaft is larger than that of the high speed shaft. The low speed gear is larger than the high speed gear.Reducer in the prime mover and working machine or actuator between the matching speed and torque transfer role, reducer is a relatively precise machine, the purpose of using it is to reduce speed, increase torque. According to the transmission series, it can be divided into single-stage and multi-stage reducer
The shaft diameter of the low speed shaft should be greater than that of the high speed shaft, because the shaft with low rotational speed bears great torque, so it needs higher strength. The middle gear is the idle wheel, as long as the strength of itself is enough, and the diameter of the high gear should be smaller than the low gear, it is possible to realize the change of speed.
The reducer is a kind of independent parts enclosed by a rigid shell gear, worm gear, gear - worm gear reducer, commonly used as a prime mover and work machine. It plays an important role in matching speed and transmitting torque between prime mover and working machine or actuator, and it is widely used in modern machinery.
According to the wheel shape of the gear mill, it can be divided into cylindrical gear reducer, bevel gear reducer and conical cylindrical gear reducer. According to the arrangement of transmission, they can be divided into expansion type, split flow type and the same shaft type reducer
