百分表是一种指示表 ,用于测量线性尺寸、形位误差和齿轮误差等。它利用齿轮传动将测杆的微量直线位移放大变成指针的角位移 ,在刻度盘上显示出来。本文针对百分表主要部位的常见故障 ,提出简单的排除方法。故障一 :指针运作迟缓。当用于推动测杆 ,并使它缓慢地恢复 ,而指针不
Dial indicator is an indicator for measuring linear dimensions, shape and position error and gear error. It uses the gear drive to move the minor linear displacement of the spindle into the angular displacement of the pointer, which is displayed on the dial. In this paper, aiming at the common faults of the main parts of the dial indicator, a simple elimination method is put forward. Fault one: the pointer slow operation. When used to push the pole and make it slowly recover, while the pointer does not
