用微电子技术改造机械设备,是当前新技术发展的方向。一二二厂根据国家“七五”期间设备改造规划,按照国际B级滚珠丝杠副的标准进行测绘、设计和试验,已于最远研制成功C620机床改造用的纵横滚珠丝杠副。 滚珠丝杠副是微机控制机床的必不可少的重要传动构件,由于具有传动效率高、驱动扭矩小、传动精度高、运动平稳、无爬行现象等优点,因此有取代面接触的滑动进给丝杠副的趋势。
Microelectronics technology to transform machinery and equipment, is the direction of the development of new technologies. One hundred twenty-two plants in accordance with the national “seven five” during the transformation of equipment planning, in accordance with international standards for B-class ball screw mapping, design and testing, has been developed in the furthest C620 machine tool used to transform vertical and horizontal ball screw pair. Ball screw pair is an important and important driving component of microcomputer control machine tool. Due to its advantages of high transmission efficiency, small driving torque, high transmission precision, smooth movement and no creeping phenomenon, it has the advantages of sliding feed wire instead of surface contact Bar deputy trend.
