摘要

设计了一种基于行星滚柱丝杠的精密传动机构。根据机电伺服系统的使用要求，分析了行星滚柱丝杠的传动特性。详细阐述了该传动机构的组成、工作原理和主要特点，分析了传动精度和传动效率这两项核心技术指标，得到了各项误差对传动精度的影响程度，如行星滚柱丝杠单向传动误差和回程误差，驱动电机、联轴器、支撑轴承、测量装置和控制系统等的中间装置误差，以及环境因素误差等，推导了传动效率与接触角、螺旋升角的相互关系。最后，构建了实验平台，测试了行星滚柱丝杠的传动精度和传动效率，结果表明其传动精度优于1.5

m，传动效率优于74%。得到的结果验证了设计的传动机构结构紧凑、承载能力强、传动效率高，传动精度好，在精密传动领域有较大的应用价值。

Abstract

A new precision transmission mechanism based on a planetary roller screw was designed. According to the requirements of an electro-mechanical serve system

the transmission characteristics of planetary roller screw were analyzed. The structure constitution

principle and characters of transmission mechanism were demonstrated in detail and the transmission accuracy and transmission efficiency of the precise planetary roller screw were analyzed. Then

the influence factors of different errors on the transmission precision were discussed

such as single-track and return-track errors of the planetary roller screw

errors of intermediate equipment

environment errors

and the relation between transmission efficiency and contact angle

spiral angle was also deduced. Finally

an experiment was established and the kernel characters

the transmission accuracy and transmission efficiency of the precise planetary roller screw were tested. The experimental results show that the transmission precision is superior to 1.5

m and the transmission efficiency is superior to 74%

which verifies that the designed transmission mechanism has compact construct

powerful load ability

higher transmission efficiency and precision

and good application values in precision transmission fields.
