Fig. 2 is little coupling shaft front axis side view;
Fig. 3 is little coupling shaft reverse side axis side view;
Fig. 4 is big coupling shaft front axis side view;
Fig. 5 is big coupling shaft reverse side axis side view.
1-angular contact bearing, 2-left shell, 3-friction plate back-up ring, 4-stiction sheet, 5-movable friction plate, 6-90 degree countersunk screw, 7-right shell body, 8-Thurst washer, 9-thrust block, 10-adjusts pad, 11-angular contact bearing, and 12-transmits gear, 13-deep groove ball bearing, 14-output shaft, 15-input shaft, 16-90 degree sinks head screw, 17-the 2nd group of steel ball, 18-individual layer bearing ripple circle, the big coupling shaft of 19-, the little coupling shaft of 20-, 21-first group of steel ball
Embodiment
When input shaft 15 moment, input shaft 15 rotates and drives first group of steel ball 21 on slope to rotate, first group of steel ball 21 promotes little coupling shaft 20 to move right, little coupling shaft 20 is linked together by 90 degree of heavy head screws 16 with big coupling shaft 19, then individual layer bearing ripple circle 18 is compressed, thus there is gap between movable friction plate 5 and stiction sheet 4, mechanism is unlocked, promote the 2nd group of steel ball 17 to move right simultaneously, 2nd group of steel ball 17 extrudes the slope of output shaft 14, and moment is delivered on output shaft 14 by the 2nd group of steel ball 17. When input shaft 15 non-moment, when output shaft 14 has load moment, load moment on output shaft 14 forces big coupling shaft 19 to left movement by the 2nd group of steel ball 17 on slope, and big coupling shaft 19 compresses movable friction plate 5 and stiction sheet 4 product moment of friction, thus output shaft 14 is braked. Adjust the pre compressed magnitude of individual layer bearing ripple circle 18 by adjustment pad 10, thus regulate and start moment (output shaft 14 non-moment rotates the moment needed for input shaft 15), improve the braking reliability of mechanism.
