近年来,在机床制造厂中为把旋转运动转变成直线运动,经常采用滚珠丝杠——螺母传动装置,即滚珠丝杠副。滚珠丝杠副作为精密元件可以同时完成位移和测量任务。滚珠丝杠副的使用价值在于其高的传动效率和使零件精确定位的可能性。这些零件可以承受载荷达100吨。在滚珠丝杠允许径向跳动为0.005毫米的情况下,按照精度级别在300毫米丝杠长度上的允许螺距误差为3～10微米。为了保证高的使用性能,在制造丝杠时必须使用精密设备,同样还需仔细选择丝杠
In recent years, in the machine tool factory for the rotation into linear motion, often using ball screw - nut gear, the ball screw pair. Ball screw pair as a precision component can complete the displacement and measurement tasks. The value of the ball screw pair is due to its high transmission efficiency and the possibility of precise positioning of the part. These parts can withstand loads up to 100 tons. In the case of a ball screw allowing radial runout of 0.005 mm, the allowable pitch error of 300 mm screw length by accuracy level is 3 to 10 μm. In order to ensure high performance, in the manufacture of lead screw must use sophisticated equipment, also need to carefully select the screw
