摘　　要：传统齿轮传动存在空回和间隙等问题,难以满足光电系统高精密传动的需求。在分析了钢丝绳和钢带传动技术特点的基础上,设计了一种基于钢丝绳传动的潜望镜用1:1测角机构,以及一种基于钢带传动的光电系统用2:1传动机构。基于光学测量的方法,采用旋变测量了钢丝绳传动机构的传动误差,采用经纬仪测量了钢带传动机构的传动误差。结果显示钢丝绳传动精度可达到分级,在-110°+135°的范围内转角误差小于3.5′;钢带传动精度可达到秒级,在-3°^+3°的范围内转角误差小于11.9″,满足了潜望镜和某光电系统性能指标要求。It is difficult for traditional gear drive to meet requirements of high precision drive of eletrooptic system because of problems of backlash and gap. Based on analysis of technical characteristics of cable and steel belt drive, 1∶1 angle measuring mechanism of periscope based on cable drive and 2∶1 drive mechanism for electrooptic system based on steel belt drive are designed. Based on optical measurement method, transmission error of cable and steel belt drive mechanism is measured by rotary transformer and theodolite respectively. Results show that transmission accuracy of cable drive can reach minute level, corner error is less than 3.5′ in range of -110°~＋135°; while transmission accuracy of steel belt drive can reach second level, angle error is less than 11.9″ in range of -3°~＋3°. In conclusion, flexible drive has high transmission accuracy and can satisfy performance requirements of electrooptical system.
