摘要
谐波减速器柔轮作为核心部件,其强度和使用寿命决定整个谐波减速器的工作性能。为了提高其寿命和承载能力,提出一种新型分体式柔轮结构。该结构基于传统的长筒型柔轮,将原先整体的柔轮杯体分成筒体和卡盘两部分,通过筒体上的卡爪与卡盘间的相互配合,共同组成一个新型杯体。首先建立柔轮的三维模型,然后导入ANSYS Workbench平台,并对所提出的新型分体式结构和整体式结构进行仿真对比分析。结果表明:在二者各结构参数相同的情况下,新型分体式结构在最大等效应力方面相对于传统的整体式结构有一定降低,进而有效提高了柔轮寿命。
The harmonic reducer flexible wheel,as the core component,its strength and service life determines the performance of the harmonic reducer.In order to improve its service life and bearing capacity,a new type of split flexible wheel structure is proposed in this paper.This structure is based on the traditional long cylinder flexible wheel;the original whole flexible wheel cup is divided into two parts:the cylinder and the chuck;then a new type of cup is formed by the cooperation between the claws on the cylinder and the chuck.Firstly,the three-dimensional model of the flexible wheel is established;then the ANSYS Workbench platform is introduced;finally,simulation and comparison analysis of the new split structure and the integral structure are carried out.The results show that with the same structural parameters,the maximum equivalent stress of the new split structure are reduced compared with the traditional integral structure,which effectively improves the service life of the flexible wheel.
