The steel ball ramp type of the present invention is without return mechanism, and for the single-direction transmission of transmission system, the device includes angular contact
It is bearing, left shell, friction plate back-up ring, static friction piece, movable friction plate, right shell body, Thurst washer, thrust bearing, adjust pad, defeated
Shaft, input shaft, 90 degree of sunk screws, second group of steel ball, individual layer bearing Bo Quan, big connecting shaft, small connecting shaft and first group of steel
Ball.
The left shell and right shell body are bolted, and the left end of the input shaft is fixed on a left side by angular contact bearing
Housing bottom, and there is annular boss on the right side of angular contact bearing, there is surface to be provided with some bellmouths, institute in the annular boss
Stating small connecting shaft correspondingly has the bellmouth of identical size in its one end, has what is be connected with big connecting shaft to insert in its other end
Hole, first group of steel ball are arranged between above-mentioned bellmouth；The big connecting shaft has and small connection axis connection in its one end
Block, there are some bellmouths in its other end, the output shaft is the quill shaft for having the shaft shoulder, is sleeved on input shaft table
Face, there is bellmouth corresponding with big connecting shaft on the shaft shoulder, wherein placing second group of steel ball, output shaft passes through angular contact
Bearing is arranged in right shell body.
The static friction piece and movable friction plate are overlapping to be arranged between friction plate back-up ring and the shaft shoulder of big connecting shaft, dynamic friction
Piece is connected with small connecting shaft by spline, and static friction piece is connected with left shell by spline；The individual layer bearing ripple circle, thrust pad

Embodiment
When 15 moment of input shaft, input shaft 15, which rotates, drives first group of steel ball 21 on slope to rotate, first group of steel
Ball 21 promotes small connecting shaft 20 to move right, and small connecting shaft 20 is connected to one with big connecting shaft 19 by 90 degree of sunk screws 16
Rise, then compress individual layer bearing ripple circle 18, so as to there is gap between movable friction plate 5 and static friction piece 4, mechanism is unlocked, together
When promote second group of steel ball 17 to move right, second group of steel ball 17 extrudes the slope of output shaft 14, and torque passes through second group of steel ball
17 are delivered on output shaft 14.When having loading moment on the non-moment of input shaft 15, output shaft 14, the load force on output shaft 14
Square forces big connecting shaft 19 to left movement by second group of steel ball 17 on slope, and big connecting shaft 19 compresses movable friction plate 5 and quiet
The product moment of friction of friction plate 4, so that output shaft 14 is braked.Individual layer bearing ripple circle 18 can be adjusted by adjust pad 10
Pre compressed magnitude, so as to adjust staring torque (non-moment of output shaft 14, rotating the torque needed for input shaft 15), improve the system of mechanism
Dynamic reliability.
