直驱工件主轴传动链测试

Test of Drive Chain on Direct Drive Workpiece Spindle

工件主轴作为蜗杆砂轮磨齿机中的关键部件,其驱动精度和响应速度对整个机床至关重要,工件主轴采用直驱结构是为了达到现代数控蜗杆砂轮磨齿机高精度、高效率的加工要求,文中对直驱工件主轴在不同砂轮转速下的跟随误差及相应转速下工件主轴和砂轮主轴均匀性误差进行了测试,为砂轮主轴工作转速的设定提供了依据。

The workpiece spindle is a key part in the worm wheel grinding machine,and its driving accuracy and response speed are of great importance to the entire machine tool.The workpiece spindle adopts the direct drive structure in order to meet the requirements of high precision and high efficiency of the modern CNC worm wheel grinding machine.This paper tests the following error of the workpiece spindle under different grinding wheel speeds,and the homogeneity error of workpiece spindle and grinding wheel is tested under the corresponding speed.It provides the basis for setting the working speed of the grinding wheel spindle.
