摘要
本文介绍电刷摩擦系数的测量装置－电刷试验转台．由正压力给定系统测量电刷的正压力，力矩反馈系统测量摩擦力对旋转中心产生的转矩，游标尺测量电刷至旋转中心距离，从而得出摩擦力．摩擦力除以正压力即摩擦系数．文中给出二个测量系统之测试结果．
A device measuring frictional factor of electric brush, Brush Testing Revolving Platform, is introduced. The upright pressure of brush is measured with the help of upright pressure giving system, the frictional torque between brush and rubbing-plate is detected by tonque feedback system and the distance from the center of brush to that of rotation is indicated by a sliding gage. Then the quantity of frictional force is obtained. And the ratio of frictional form to upright paseare is the wanted frictional factor. The accuracy of measuring system and the experimental results of testing revolving platform are also given.
