摘要/Abstract

摘要： 为了确定钢丝绳精密传动中预紧力、负载、绳组数、转速对传动精度的影响，搭建了实验测试平台，测量了不同组钢丝绳传动时的传动误差。结果表明：传动误差主要由传动空回和滑移误差组成，绳组数一定时，增大预紧力降低了传动空回，但增大了滑移误差，总的传动误差呈增大趋势；增大负载使传动空回和滑移误差同时增大，总的传动误差明显增大；随着钢丝绳组数的增加，传动空回略有降低，滑移误差显著降低，总的传动误差降低；轮的转速对传动误差无影响。因此，在一定负载条件下，增加钢丝绳组数、降低预紧力是提高传动精度的有效途径，这些结果可为工程设计提供参考。

Abstract: In order to determine the effects of preload force, load, rope number and rotate speed on cable drive transmission accuracy, an experiment is conducted to measure the transmission error under the condition of different cable numbers. The results show that the transmission error is composed of transmission backlash and slip error. When cable number remains constant, the transmission backlash decreases and the slip error increases with the increase in preload force. The transmission error increases with the increase in preload force. The transmission backlash and slip error increase with the increase in load, which causes a larger transmission error. When cable number is increased, the transmission backlash decreases slightly while the slip error decreases significantly. The influence of rotate speed on the transmission error can be ignored. What is proved to be an effective way for improving transmission precision is to increase rope number or decrease preload force under the condition of given load. Key

Key words: mechanics, cabledrive, transmissionaccuracy, preloadforce, load
