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
What the present invention relates to is a kind of orthogonal formula steering wheel planetary reducer transmission device.
Background technique
The orthogonal formula harmonic wave drive speed reducer is because its reduction speed ratio is large, volume is little, lightweight, output torque is large, the transmission accuracy high, be widely used in all trades and professions multiple fields, but, its orthogonal formula harmonic wave drive speed reducer is subject to the impact of two-stage transmission and harmonic wave deformation wave, the transmission efficiency of its product does not increase all the time, the harmonic speed reducer efficient of single-stage only has about 75%, add the bevel gear drive of one-level, total transmission efficiency just only has about 50%, user for the high use occasion of ask for something transmission efficiency, must be subject to certain restrictions, have certain defective.
The design of orthogonal formula planetary reducer also is to realize by double reduction mechanism, one-level is bevel gear transmission equally, one-level is single ripple planet eccentric speed reduction structure in addition, its volume is equal to the volume with the orthogonal formula harmonic driving, mounting interface is also consistent with it, possesses too that reduction speed ratio is large, volume is little, lightweight, output torque large, the transmission accuracy high.The transmission efficiency of its product can realize about 90%.Also relatively improve same its working life.
Summary of the invention
The purpose of this invention is to provide a kind of orthogonal formula planetary reducer transmission device, fill up orthogonal formula harmonic wave drive speed reducer transmission efficiency and life-span not enough, realize the characteristics such as the reducer reduction speed ratio is large, volume is little, lightweight, output torque is large, transmission accuracy is high, transmission efficiency is high, the life-span is long.
The orthogonal formula planetary reducer, it is characterized in that comprising motor high speed input part, one-level bevel gear gearing down pair, secondary planet transmission reduction gearing mechanism, and described one-level bevel gear drive comprises bevel pinion, bevel gear wheel, bevel pinion is by on the motor shaft of straight pin tight joint in motor high speed input part, the bevel gear wheel structure connects with planetary pinion in the secondary planet transmission reduction gearing mechanism by bearing with eccentric structure; Described secondary planet transmission is slowed down and is comprised: compound planet gear, with the housing of ring gear; Planetary rotation is subjected to the restriction of housing internal gear and planetary pinion to do plane motion; Planetary pinion and internal gear are the meshed transmission gear of a pair of few teeth difference, and planetary pinion is a duplex gear, and output shaft meshes with planetary another connection gear simultaneously, are a pair of few teeth difference engagement output form equally; Resetting shaft connects firmly mutually by screw and setting circle pin and output shaft, and bevel gear wheel endoporus and potentiometer that the while resetting shaft passes through again with eccentric structure link.
Motor of the present invention is realized the quadrature transmission by the bevel gear of pair of orthogonal engagement, driving double-planetary gear by the bevel gear wheel with eccentric structure rotates, planetary rotation is subjected to the restriction of internal gear, planet crop rotation plane motion, namely planet wheel was both made circular movement around fixed axis, also do rotation motion around self axis, planetary pinion and internal gear are the meshed transmission gear of a pair of few teeth difference, sun gear meshes with planetary another connection gear simultaneously as output mechanism, be a pair of few teeth difference engagement output form equally, thereby realized the purpose of slowing down.
The present invention has the characteristics such as compact structure, volume is little, velocity ratio is large, transmission accuracy is high, transmission efficiency is high, the life-span is long.
