以旋转矢量（rotate vector，RV）减速器为研究对象，分析了RV减速器静态回差的影响因素，建立了矩阵形式的静态回差分析数学模型，并推导出了针齿中心圆半径误差等15项误差的误差分配数学模型．以CSRV-160E-171型减速器为实例进行了误差分配计算，并基于误差分配结果进行PROE三维建模，建立了包含15项误差的虚拟样机模型1、模型2以分别模拟静态回差上、下限．建立了基于ADAMS的RV减速器回差仿真分析模型，提出了静态回差测试方案．仿真得出回差值为0．18′-1．19′，与设计值相似．仿真结果证明了误差分配数学模型的正确性．

The rotate vector （RV） reducer was taken as a research object in this paper. The mathematical model of static backlash analysis was formulated in the form of matrix after analyzing the static backlash influencing factors of RV reducer. Then the mathematical model of error distribution was deduced which consisted of 15 errors including pin gear central circle radius error. The CSRV-160E-171 reducer was used as an example to distribute the error. The vir- tual prototype model 1 and model 2, which contained 15 errors, were built by PROE based on the result of the error distribution to simulate upper and lower limit values of static backlash. The backlash simulation analysis model of RV reducer was built based on ADAMS and the static backlash test scheme was put forward. The value of backlash simulation is 0.18＇--1.19＇, which is similar to the designed value. The results indicate that the error distribution mathe- matical model was correct.
