偏心揺動型減速機

Eccentric rocking type reduction gear

Abstract

【課題】軸方向に短い偏心揺動型減速機を提供する。 【解決手段】内歯21aを有する内歯歯車体21と、内歯歯車体の内歯に噛み合う外歯を有し偏心揺動する外歯歯車23と、外歯車に係合する複数のクランク機構部材27と、複数のクランク機構部材を回転自在に支持する支持体25、31とを備え、内歯歯車体または支持体から回転が出力される偏心揺動型減速機であって、ブレーキ手段70が複数のクランク機構部材の少なくとも二個に設けられている。 【選択図】 図1
PROBLEM TO BE SOLVED: To provide an eccentric rocking type reduction gear short in the axial direction which allows reduction in the number of friction plates of each braking means by reducing braking load of each brake means since a brake means is provided on at least two of a plurality of crank mechanism members. SOLUTION: The eccentric rocking type reduction gear is equipped with an internal gear body 21 having internal teeth 21a, an external gear body 23 which has external teeth meshed with the internal teeth of the internal gear body and eccentrically rocks, a plurality of the crank mechanism members 27 engaged with the external gear, and supporting members 25, 31 for freely rotatably supporting a plurality of crank mechanism members, wherein rotation is output from the internal gear body or the supporting members. The brake means 70 is provided to at least two of a plurality of the crank mechanism members. COPYRIGHT: (C)2009,JPO&INPIT
