该元件是国家“七五”科技攻关项目,已于1991年1月18号在广州通过专家鉴定。该元件已被国家专利局授予实用新型专利,专利号为89216911.7。外形图如图1所示。1 原理该缸是靠内斜齿轮(活塞)和外斜齿轮(活塞杆)的啮合传动来传递摆动力,即活塞在缸筒内作直线运动,通过内啮合使活塞杆作摆动(旋转)运动。通过无触点磁性开关控制摆动角度。该缸为轴向输出扭矩,而国内目前有的齿轮齿条式摆动气缸是径向输出扭矩。 The component is the national “Seventh Five-Year” scientific and technological projects, in January 18, 1991 in Guangzhou by experts. The element has been granted by the State Patent Utility Model Patent No. 89216911.7. Figure shown in Figure 1. 1 Principle The cylinder is based on the internal helical gear (piston) and the external helical gear (piston rod) meshing transmission to transmit the swing force, the piston in the cylinder for linear motion, the piston rod through the internal swing (rotation) movement . Through the contactless magnetic switch to control the swing angle. The cylinder for the axial output torque, and some domestic rack and pinion swing cylinder radial output torque.
