【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。
[Abstract]:The traditional gear transmission has some problems such as empty return and clearance, which is difficult to meet the demand of high precision transmission of photoelectric system. Based on the analysis of the technical characteristics of steel wire rope and steel belt transmission, a 1:1 angle measuring mechanism for periscope based on steel wire rope transmission and a 2:1 transmission mechanism for photoelectric system based on steel belt transmission are designed. Based on the method of optical measurement, the transmission error of wire rope transmission mechanism is measured by rotation, and the transmission error of steel belt transmission mechanism is measured by theodolite. The results show that the precision of wire rope transmission can be classified, and the angle error is less than 3.5% in the range of -110 掳135 掳, and the accuracy of steel belt transmission can reach the second level, and the angle error is less than 11.9 "in the range of -3 掳~ 3 掳." It meets the performance requirements of periscope and a photoelectric system.
