The bottom of the brake pad is provided with spring block, is connected with spring below the spring block, the spring bottom end is connected with
Reductor, the reductor are connected with motor.
The bottom of the spring is connected with nut, and the nut is socketed in the bottom of regulation power screw.The nut bag
Top and bottom are included, top and bottom are cylindrical structure, and upper end is directly less than lower end diameter.Nut is with regulation tension force spiral shell
The rotation of bar is walked upwards, i.e., applies thrust, increasing friction force degree, so as to realize the control rotated to drum to spring.
The outside of the brake pad is provided with brake pad overcoat, and the brake pad overcoat is fixed on reductor.
The output end of the reductor is connected with regulation power screw.
The advantages of the application is：
1st, the frictional force that frictional disk is subject to can be adjusted in real time for the automatic tension-adjusting device of the application, motor
Switch and control the vertical upper-lower position for adjusting power screw, the brake pad outside regulation power screw drive is upwardly or downwardly
Motion, brake pad are realized the buffering of power and resetting for brake pad by the pulling force of spring, the friction between brake pad and frictional disk
The size of power, then determine the rotating speed of frictional disk, and then realizes the regulation of tension force.
2nd, the application pushes up spring, spring push the spring block by nut, and spring block promotes brake pad, structure
Simple and durable, and failure is not susceptible to, it is adapted to industrial production.
