| Abstract: | 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. |
