Problems solved by technology

However, the pitch and roller radius of the precision roller chain for standard double-row transmission used in this invention are restricted by standard parameters, and the practical transmission ratio of single-stage harmonic deceleration should not be too large, and the harmonic deceleration cannot be fully utilized. Mechanism can realize the advantage of large transmission ratio

Abstract

This invention discloses one involute cycloid roller chain planet resonance wave compound speed reducing drive structure, which comprises the following parts: one involute gear with input axis connected to center; two or three evenly distributed involute planet gear; one parallel roller chain rings; one cycloid inner gear with less gears connected to the output axis; one zero gear difference range cycloid gear,

Description

technical field [0001] The invention relates to a large transmission ratio reduction transmission machine with an input shaft and an output shaft coaxial, in particular to an involute cycloid roller chain planetary harmonic compound reduction transmission mechanism. Background technique [0002] The existing coaxial-type large transmission ratio reduction transmission machinery can be mainly divided into three categories: involute planetary reduction mechanism with small tooth difference, cycloidal pinwheel reduction mechanism and traditional harmonic reduction mechanism. In the involute planetary reduction mechanism with small tooth difference, in order to avoid tooth tip interference, a large meshing angle transmission must be used, and the radial load is large. In the cycloidal pin gear reduction mechanism, in order to avoid redundant cutting of the cycloidal gear, a short coefficient is introduced. When the transmission ratio is large, the tooth height of the cycloidal g...
