A reducer is a transmission machine that is used to reduce the speed of an electric motor or other prime mover and increase its torque. Reducers can be divided into the following types according to different classification methods:
According to the type of transmission: the reducer can be divided into gear reducer, worm gear reducer and planetary gear reducer. Among them, the gear reducer is a commonly used one, which transmits torque and power through the meshing of gearsThe worm gear reducer is decelerated by the meshing of the worm gear and the wormThe planetary gear reducer is decelerated through the meshing of planetary gears.
According to the reduction ratio: the reducer can be divided into a one-stage reducer and a multi-stage reducer. The reduction ratio of the primary gear unit is usually small, which is suitable for situations where a higher speed needs to be reduced;The multi-stage gear unit has a larger reduction ratio and is suitable for situations where lower rotational speeds need to be reduced.
According to the output shaft form: the reducer can be divided into a straight shaft reducer and a parallel shaft reducer. The output shaft of the right-angle shaft reducer is perpendicular to the input shaft, which is suitable for occasions that require vertical outputThe output shaft of the parallel shaft reducer is parallel to the input shaft, which is suitable for occasions that require parallel output.
According to the installation method: the reducer can be divided into horizontal reducer and vertical reducer. The output shaft of the horizontal reducer is horizontally placed, which is suitable for occasions that require horizontal output;The output shaft of the vertical reducer is vertically placed, which is suitable for occasions that require vertical output.
According to the lubrication method: the reducer can be divided into two types: oil-immersed type and oil-injected type. The gears and bearings of the oil-immersed reducer are immersed in oil, which is suitable for low-speed and high-torque occasionsThe gears and bearings of the oil-injected reducer are lubricated by the fuel injector, which is suitable for high-speed and low-torque occasions.
In short, there are various types of reducers, and it is necessary to choose the right type according to the specific transmission requirements.
