[0035] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0036] like Figure 1 The figure shows a schematic diagram of a connecting shaft structure for torque transmission in the present application, in which a bolt 103 connects a left transmission structure 101 and a right transmission structure 102, and the end faces of the left transmission structure 101 and the right transmission structure 102 are in close contact. When either the left transmission structure 101 or the right transmission structure 102 rotates, the two structures transmit torque to the other structure through the end face, and mutual interference occurs when the torques are in different directions or at different speeds.

[0037] In order to isolate the transmitted torque between the left transmission structure 101 and the right transmission structure 102 which are bolted together, the present application provides a stopping device for isolating the torque transmission.

[0038] like Figure 2 As shown, the stopping device provided by the present application includes a clamping ring 10 , a left retaining ring 20 , a right retaining ring 30 , a stopping bolt 40 , a clamping ring 50 and a gasket 60 .

[0039] The cross-sections of the left retaining ring 20 and the right retaining ring 30 are both L-shaped, and the inner corners of the L-shaped structures form stop structures. The stop structures of the left retaining ring 20 and the right retaining ring 30 are arranged opposite to each other, and the clamping ring 10 is arranged in the stop structures, so as to radially clamp and limit the left retaining ring 20 and the right retaining ring 30. The outer end faces of the L-shaped structures of the left retaining ring 20 and the right retaining ring 30 are in contact with the end faces of the left transmission structure 101 and the right transmission structure 102 respectively.

[0040] The gasket 60 is disposed between the left retaining ring 20 and the right retaining ring 30, and can adjust the contact tightness of the left transmission structure 101 and the right transmission structure 102 to complete the position adjustment. In some embodiments of the present application, the gasket 60 can be a metal structure capable of bearing, or a wear-resistant non-metallic ceramic material.

[0041] In the preferred embodiment of the present application, the left retaining ring 20 and the right retaining ring 30 are symmetrically arranged about the center line of the gasket 60 .

[0042] Further, one of the left retainer 20 and the right retainer 30 is a split retainer. This application takes the left retainer 20 as an example for explanation, and the left retainer 20 includes a half-ring upper retainer 21 and a half-ring lower retainer 22, which are combined into a full-ring left retainer and assembled on the bolt 100.

[0043] The bolt 100 passes through the inner diameters of the left retainer 20 and the right retainer 30, and the clamping ring 50 is installed in the annular groove provided on the bolt 100 and cooperates with the right retainer 30, which is used to axially limit the right retainer 30 and the gasket 60. Among them, a radial protrusion can be provided on the inner side of the right retainer 30, and the radial protrusion and its inner side surface form an inner stop structure, and the inner stop structure cooperates with the clamping ring 50 to realize the axial limit of the right retainer 30.

[0044] In some embodiments of the present application, the collar 50 is an open collar, so that it can be retracted and expanded. Further, the collar 50 is made of elastic metal material.

[0045] The stop bolt 40 cooperates with one of the upper half ring retainer 21 and the lower half ring retainer 22, and is located in the arc-shaped groove provided on the bolt 100, and is used to isolate the torque transmission on both sides of the stop device. During installation, the stop bolt 40 is installed on one of the half ring retainers, and radially assembled in the arc-shaped groove on the bolt 100, and then the bolt 100 is pushed to make the combined full ring left retainer cooperate with the gasket 60 and the clamping ring 10, so as to realize the installation of the stop device at any position of the bolt to be assembled.

[0046] In some embodiments of the present application, the thickness of the gasket 60 can be adjusted according to installation requirements, thereby adjusting the thickness of the entire stopper 200. Furthermore, the length of the clamping ring 10 can also be adjusted according to installation requirements.

[0047] In some embodiments of the present application, the stop device installation steps are as follows: Figure 4 As shown:

[0048] S1, installing the clamping ring 50 in the bolt clamping groove;

[0054] S8, install the upper retainer of the half ring, and the combined left retainer of the whole ring cooperates with the gasket 60 and the clamping ring 10. After the installation of the brake device is completed, the transmission device can be installed on the left and right sides respectively.

[0055] The stopping device for isolating torque transmission provided by the present application can be installed from the middle section of the bolt by setting two semi-annular guards, which solves the limitation that conventional stopping washers must be installed from the end of the bolt inward; the retaining ring 50 is installed in the annular groove set on the bolt 100, and cooperates with the right guard ring 30 to achieve one-way stopping in the flanging direction of the right guard ring; the stopping bolt 40 is radially installed on any semi-annular guard ring, and the stopping bolt 40 cooperates with the arc-shaped retaining groove on the bolt 100 to isolate the torque transmission on both sides of the stopping device; the thickness adjustment of the stopping device is achieved by setting a gasket and a clamping ring.

[0056] The present application can isolate the torque transmission of the transmission structures on both sides of the bolt, prevent torque interference of the transmission structures on both sides, ensure the overall installation accuracy of the bolt by adjusting the thickness, and realize one-way axial stop to prevent axial load transmission. It can be installed at any axial position of the bolt and has a wide range of applications.
