iRV robot speed reducer

Abstract

The invention discloses an iRV robot speed reducer. The iRV robot speed reducer comprises a speed reducer shell. An eccentric shaft is arranged in the middle in the speed reducer shell, one axis of the eccentric shaft is coaxial with the shell, the middle of the outer wall of the eccentric shaft is fixedly sleeved with two cycloid bearings, the two cycloid bearings are coaxial with the two axes ofthe eccentric shaft correspondingly, and the outer walls of the two cycloid bearings are fixedly sleeved with cycloid gears. According to the iRV robot speed reducer, as the pressure angle is changedto be larger than 20 degrees and smaller than 40 degrees, while the transmission ratio is increased, the engagement depth is increased, an oil film is easily formed, meanwhile, the problem of interference is solved, interference of the pressure angle being 30 degrees is 1 / 2 that of the pressure angle being 20 degrees, even the torque is changed to be 2-3 times of original torque, connection is carried out through 3-8 pin columns, the rigidity of connection of a front flange and a rear flange is improved, the gears can be machined through an existing machining process and precision, and no trouble is added to large-batch production.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to an iRV robot reducer. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. Although the existing RV, cycloidal pinwheel and other reducers have different structures, there is one The common feature is that the inner tooth trochoidal parallel curve gear and the pin gear ring gear carry out differential tooth cycloid transmission. The patent No. ZL201510676854.6 discloses a precision reduction transmission mechanism, which is used to provide a two-stage serial involute gear cycloid transmission reduct...
