[0003] At present, the reduction unit of most planetary gear reducers on the market has the problem of backlash in the meshing of the gears under working conditions, which directly affects the accuracy and efficiency of the reducer. Therefore, the traditional planetary gear reducer has a large hysteresis , and the shortcomings of low precision and efficiency, even if the overall precision of the reducer with this structure is improved or the accuracy can be guaranteed by introducing foreign planetary gear reducers, the production cost is high
[0004] In order to overcome the defect of large backlash in the above-mentioned gear reducer, some reducers use a conical friction wheel structure to achieve the purpose of deceleration, but the conical friction wheel has a large axial force under working conditions, making the structure complicated , and the production efficiency is low, and the production cost is high

Description
technical field [0001] The invention specifically relates to a speed reduction assembly. Background technique [0002] The existing deceleration assembly (reducer) is an independent closed transmission device between the prime mover and the working machine, which is used to reduce the speed and increase the torque to meet the work needs. At present, gear reducers, worm gear reducers and planetary gear reducers are widely used in reducers. Different types of motors need to be matched with reducers of different structures to meet the working needs. [0003] At present, the reduction unit of most planetary gear reducers on the market has the problem of backlash in the meshing of the gears under working conditions, which directly affects the accuracy and efficiency of the reducer. Therefore, the traditional planetary gear reducer has a large hysteresis , and the shortcomings of low precision and efficiency, even if the overall precision of the reducer with this structure is imp...
