The bottom of the connecting claw 4 at the flange 2 abuts, the brake wheel 3 is wrapped around the left flange 1 and distributed coaxially with the left flange 1, and the spokes of the brake wheel 3 are connected to the rear end of the connecting claw 4 of the left flange 1. They are connected to each other by positioning bolts 6. The outer diameter of the brake wheel 3 is 1.3 to 3 times the diameter of the connecting jaw 4, and the distance between the rear end of the brake wheel 3 and the rear end of the left flange 1 is 1/the length of the left flange 1. 4-1/3, the front end of the brake wheel 3 and the rear end of the connecting jaw 4 connected to the right flange 2 are evenly distributed. The left and right end faces of the elastic base body 5 are at least A disc spring 7, and the disc spring 7 is coaxially distributed with the left flange 1 and the right flange 2, and the contact surfaces of the connecting jaws 4 connected by the left flange 1 and the right flange 2 Set the elastic liner 8.

[0016] At the same time, the brake wheel 3 and the outer surface of the left flange 1 are slidably connected to each other through at least two sliding grooves 9, and the sliding grooves 9 are evenly distributed around the axis of the left flange 1 and parallel to the axis of the left flange 1. distributed.

[0017] In a further optimization, at least one positioning pin hole 10 is provided on the side surfaces of the left flange 1 and the right flange 2, and the positioning pin hole 10 axis is perpendicular to the axis of the left flange 1 and the right flange 2.

[0018] For further optimization, a number of deformation cavities 11 are evenly distributed in the elastic base 5, and the axis of the deformation cavity and the axis of the elastic base 5 form an angle of 0°-90°.

[0019] In the specific embodiment of the present invention, the left flange, right flange, brake wheel, connecting jaws, and elastic base constituting the present invention are first assembled, and then the assembled present invention is passed through the left flange and right flange. It is connected with the shaft workpiece to be connected, and at the same time the brake wheel and the external brake mechanism are connected to each other, thereby completing the assembly of the present invention.

[0020] In the operation of the present invention, the shaft workpiece is connected and positioned through the left flange and the right flange, and the driving force transmission between the left flange and the right flange is realized through the connecting jaws, and the left flange, the right flange, and the connection The jaws jointly improve the structural strength and impact resistance of the elastic coupling; at the same time, the elastic matrix and the elastic lining layer jointly improve the elastic deformation ability of the elastic coupling of the present invention, so as to effectively eliminate the axial movement and impact of the coupling during operation. The radial jump action exerts force to improve the stability of the coupling operation. Finally, during the operation, the braking force is directly applied to the braking wheel through the braking mechanism, and the elastic coupling of the present invention is assisted by the loading and positioning of the braking mechanism. At the same time, it is also possible to adjust the rotational speed of the elastic coupling of the present invention during operation, so that the rotational speed of the elastic coupling of the present invention is consistent with the rotational speed of the shaft workpiece, and prevents the elastic coupling of the present invention from being higher However, the situation of being damaged by large torque occurs, thereby improving the stability and reliability of the operation of the elastic coupling of the present invention.

[0021] The invention has simple structure, flexible and convenient use, and good versatility. On the one hand, it can effectively improve the structural strength and load-bearing capacity. While greatly improving the power transmission capacity and stability, it can effectively reduce the axial displacement generated in the power transmission process. The dynamic and radial jump actions forcefully improve the operation stability of the coupling equipment. On the other hand, it also has good positioning and braking capabilities, which can improve the coaxiality of the coupling operation, and also realize the coupling and The purpose of synchronous braking and speed regulation of the shaft workpiece is to effectively eliminate the damage to the coupling structure caused by the inertia of the coupling and the shaft workpiece during operation.
