一种新型行星式分度凸轮机构的研究

在分析间歇传动机构创新研究成果的基础上,基于行星轮系齿轮传动的原理,从高速、高分度精度出发,提出了一种新型分度凸轮传动机构。该分度机构将行星轮系的一个中心轮设计为凸轮,推动行星轮和系杆实现分度输出运动。本文应用张量法建立了该类机构凸轮的廓线方程,并对该类机构的结构与设计参数进行了系统的分析。最后,通过编程给出了该类分度机构的计算机仿真实例。该类分度机构具有结构紧凑、输入输出同轴等特点,补充和丰富了平行轴式间歇传动机构的产品类型,可成为间歇分度和步进输送机构的新型产品。

Study on a Novel Indexing Mechanism

On the basis of innovation design of intermittent transmission of indexing cam mechanism,a novel indexing mechanism with high-speed and high indexing precision was proposed according to principles of planetary sliding tooth gearing and mechanism combination.Profile equations of cam in this kind of mechanism were derived in vector form.Structure and design parameters were analyzed systematically.Examples of computer simulation were given.This kind of mechanism has the advantage of compact structure,coaxial input and output.It enriches types of parallel axial intermittent transmission mechanisms.This mechanism may become a new generation product of intermittent indexing transmission mechanisms.
