摘 要
近年来双曲柄环板式少齿差行星传动减速机由于其简单、结构紧凑、高传动比和大载重量的特点,发展非常迅速。但是仍存在一些问题,包括:噪音大,高温,以及在高速运行,重载和高传动比情况下,轴承的早期失效。严重影响其大众化进程,这些问题迫切需要解决。
为了解决高速和重载运行情况下环减速器的高振动和噪音问题,本文基于现存减速机的工作原理进行多曲柄低振动少齿差减速机的研究。
本文研究的新型多曲柄低振动少齿差减速机:由唐倩老师研究并申请专利的多曲柄低振动少齿差传动是一类特殊形式的少齿差行星传动。不仅具有结构简单,传动比大,传动效率高,承载和过载能力强,制造成本低,振动、噪声小等优点,同时明显改善了曲轴与轴承的受力状况,延长了使用寿命,特别适合大负载的工况。论文从以下几个方面进行分析与探讨:①对该减速机进行结构参数设计;②本文基于Pro/ENGINEER Wildfire建立多曲柄低振动少齿差减速机的三维模型,并对其进行虚拟装配;③基于有限元分析软件ANSYS,利用有限元分析法对少齿差减速机进行齿面接触分析。

ABSTRACT
Ring reducer is developed very quickly in recent year due to its simple and compact structure, high driving ratio, large loading capacity and high driving efficiency. But some problems, including great noise, high temperature and the early-worn of bearings occurring under the condition of high-speed operation, heavy loading and high transmission ratio, influenced seriously its popularization progress and are urgent to be solved.
In order to solve the high vibration and noise problems of ring reducer under the condition of high–seed and heavy-load operation, a new reducer with multi-crank and low exciting force and small tooth differences is suggested is this article, which is based on study of driving principle of current ring reducer.
A reducer with multi-crank and low exciting force and small tooth differences is a new-type reducer; It was researched and patented applications by Prof.Qian Tang is from Chongqing University. The reducer not only used for its advantages such as simple, high-transmission ratio, high-transmission efficiency, large loading capacity, low manufacture cost and low noise. also improved the situation of crankshaft and bearings in force, and prolong the service life, especially for a large load conditions. This article studies in the following aspects: ① About the structural design of Reducer; ② We establish the three-dimensional structure of the reducer model with the software Pro/ENGINEER Wildfire in the paper; ③ Based on the finite element analysis software ANSYS, We can make the analysis for tooth contact.
Key words: Ring reduce, Modeling, Virtual assemble, Finite element analysis
