Orthodox planet reducer

Abstract

The invention aims to provide an orthogonal planetary speed reducer transmission device, which overcomes the defects of transmission efficiency and service life in an orthogonal harmonic transmission speed reducer. The orthogonal transmission of a novel motor is realized by a pair of orthogonally engaged bevel gears, a large bevel gear with an eccentric structure drives a dual planetary wheel to rotate, the planetary wheel does circumferential movement around a fixed axis and also does rotary movement around a self axis, the planetary wheel and an inner gear are in the engagement transmission of one pair of gears with small tooth difference, and a sun gear is used as an output mechanism and is simultaneously engaged with the other gear of the planetary gear also in the engagement output of one pair of gears with small tooth difference. The orthogonal planetary speed reducer has the advantages that the speed reduction ratio is large, the size is small, the weight is light, the output torque is large, the transmission precision is high, the transmission efficiency is high, the service life is long, and the like.

Description

technical field [0001] The invention relates to a planetary reducer transmission device for an orthogonal steering gear. Background technique [0002] Orthogonal harmonic drive reducer has been widely used in various fields in various industries due to its large reduction ratio, small size, light weight, large output torque, and high transmission accuracy. However, its orthogonal harmonic The transmission reducer is affected by the two-stage transmission and the harmonic deformation wave, and the transmission efficiency of its products cannot be improved. The efficiency of the single-stage harmonic reducer is only about 75%. The efficiency is only about 50%. For some users who require high transmission efficiency, they must be limited and have certain defects. [0003] Orthogonal planetary reducer design is also realized by two-stage reduction mechanism, the first stage is also a bevel gear transmission mechanism, and the other stage is a single-wave planetary eccentric red...
