[0002] With the increasing requirements for low carbon, the new energy vehicle industry is developing day by day. Among them, the demand for drive motors has increased significantly, pushing the development of the motor industry to a new height, and putting forward higher requirements for the performance, safety factor, and service life of the motor. In the drive motor, the speed of the motor is mainly regulated by controlling the voltage frequency. When adjusting the speed, capacitive induction will be generated on the output shaft of the motor to form a common mode voltage, which will be discharged on the output shaft of the motor, causing pits and electrical corrosion spots on the surface of the output shaft of the motor, damaging the output shaft of the motor, causing the motor to fail, thereby affecting the overall facility operation. Therefore, it is necessary to protect the output shaft of the motor.

[0003] At present, the electrical corrosion protection components of the output shaft of the motor are mainly insulating bearings, conductive rings and other components.

[0004] At present, when manufacturing a conductive ring, in the process of radially arranging a plurality of conductive fibers on the inner side wall of the ring body, each conductive fiber needs to be arranged on the inner side wall of the ring body and then each conductive fiber needs to be fixed. However, each conductive fiber is relatively small, so positioning is relatively complicated. Summary of the invention

[0005] The purpose of the present application is to address the shortcomings of the prior art by providing a mounting ring frame so that the conductive fibers can be wound around the mounting ring frame and then sheared after the mounting ring frame is fixed to the main ring frame and the auxiliary ring frame, thereby eliminating the step of positioning each conductive fiber, thereby saving time for installing the conductive fibers and solving the problem of cumbersome conductive fiber positioning in the traditional production method.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0010] Preferably, the outer diameter of the secondary ring frame is equal to the inner diameter of the main ring frame.

[0011] Preferably, the inner diameter of the secondary ring frame is equal to the inner diameter of the annular convex ring.

[0012] Preferably, an expansion ring groove is coaxially provided on the inner circumferential surface of the main ring frame on the side facing away from the annular convex ring, the inner diameter of the expansion ring groove is larger than the inner diameter of the main ring frame, and the outer diameter of the secondary ring frame is equal to the outer diameter of the expansion ring groove.

[0013] Preferably, the distance from the expansion ring groove to the annular convex ring is greater than the distance between two end faces of the mounting ring frame.

[0014] Preferably, the side wall of the expansion ring groove facing away from the center of the expansion ring groove is projected on a direction parallel to the axis of the expansion ring groove as a first inclined surface, and the outer circumferential wall of the secondary ring frame is projected on a direction parallel to the axis of the expansion ring groove as a second inclined surface matching the first inclined surface.

[0028] like Figure 1-5 As shown, a conductive ring comprises a main ring frame 1, a secondary ring frame 2, a mounting ring frame 3, and conductive fibers 4. The secondary ring frame 2 is coaxially fixed to the main ring frame 1, the mounting ring frame 3 is coaxially located between the main ring frame 1 and the secondary ring frame 2, and the mounting ring frame 3 is uniformly and radially provided with a plurality of conductive fibers 4 pointing to the center of the mounting ring frame 3 around the center of the mounting ring frame 3.

[0029] In this embodiment, when in use, the conductive fiber 4 is first wound on the mounting ring frame 3, and the winding method is that the conductive fiber 4 is parallel to the end face of the mounting ring frame 3, and the conductive fiber 4 passes through the center of the mounting ring frame 3, then the mounting ring frame 3 is coaxially placed in the main ring frame 1, and then the auxiliary ring frame 2 is coaxially covered on the mounting ring frame 3, so that the main ring frame 1 and the auxiliary ring frame 2 clamp the mounting ring frame 3, and then the main ring frame 1 and the auxiliary ring frame 2 are fixed together, so that the main ring frame 1, the auxiliary ring frame 2, and the mounting ring frame 3 are fixed together, and then, by shearing, part of the conductive fiber 4 in the ring of the mounting ring frame 3 is sheared off, and after shearing, the ends of all the conductive fibers 4 facing the center of the mounting ring frame 3 are located on the same virtual circle, thereby forming a plurality of radial conductive fibers 4; the radius of the virtual circle is smaller than the inner diameter of the main ring frame 1, the inner diameter of the auxiliary ring frame 2, and the inner diameter of the mounting ring frame 3, and the radius of the virtual circle is greater than 0. In this way, a conductive ring is obtained. This manufacturing method is relatively simple and there is no need to position and limit each conductive fiber 4.

[0030] As a preferred mode, a plurality of notches 5 are evenly arranged on the outer circumferential surface of the mounting ring frame 3 around the center of the mounting ring frame 3, and the two ends of the conductive fiber 4 are located at the notches 3, and the two ends of each conductive fiber 4 point to the center of the mounting ring frame 3. After the notches 5 are arranged, it is convenient to wind a whole conductive fiber 4 on the mounting ring frame 3, and the conductive fiber 4 wound on the mounting ring frame 3 will not slide along the outer circumferential surface of the mounting ring frame 3.

[0031] As a preferred embodiment, an annular convex ring 6 is coaxially provided on one side of the inner circumferential surface of the main ring frame 1, and the inner diameter of the secondary ring frame 2 is smaller than the inner diameter of the main ring frame 1. By providing the convex ring 6, it is convenient for the convex ring 6 to clamp the mounting ring frame 3 and the conductive fiber 4 with the secondary ring frame 2 on one side facing the secondary ring frame 2.

[0032] As a preferred embodiment, the outer diameter of the secondary ring frame 2 is equal to the inner diameter of the main ring frame 1. After such a configuration, the secondary ring frame 2 can be embedded in the main ring frame 1, and then the secondary ring frame 2 and the convex ring 6 restrict the mounting ring frame 3, thereby preventing the mounting ring frame 3 from falling off from the end surface of the main ring frame 1. In actual use, after the secondary ring frame 2 is embedded in the main ring frame 1, there is an interference fit between the secondary ring frame 2 and the main ring frame 1, and the secondary ring frame 2 is pressed into the main ring frame 1 by riveting.

[0033] As a preferred embodiment, the inner diameter of the secondary ring frame 2 is equal to the inner diameter of the annular convex ring 6. After such arrangement, the inner diameters of the upper and lower ends of the whole formed by the secondary ring frame 2 and the main ring frame 1 are equal, so as to avoid shaking after the whole formed by the secondary ring frame 2 and the main ring frame 1 is sleeved on the output shaft of the motor.

[0034] As a preferred embodiment, an expansion annular groove 7 is coaxially provided on the inner circumferential surface of the main ring frame 1 on the side facing away from the annular convex ring 6, the inner diameter of the expansion annular groove 7 is larger than the inner diameter of the main ring frame 1, and the outer diameter of the secondary ring frame 2 is equal to the outer diameter of the expansion annular groove 7. The design of the expansion groove 7 prevents the secondary ring frame 2 from squeezing the conductive fiber 4 and the mounting ring frame 3 during the process of pressing the secondary ring frame 2 into the main ring frame 1.

[0035] As a preferred embodiment, the distance between the expansion ring groove 7 and the annular convex ring 6 is greater than the distance between the two end faces of the mounting ring frame 3. With this design, after the mounting ring frame 3 is installed between the main ring frame 1 and the auxiliary ring frame 2, there is still enough space to accommodate the conductive fiber 4.

[0036] As a preferred method, Figure 4 As shown, the side wall of the expansion ring groove 7 facing away from the center of the expansion ring groove 7 is projected on a plane parallel to the axis of the expansion ring groove 7 as a first inclined plane, and the outer circumferential wall of the secondary ring frame 2 is projected on a plane parallel to the axis of the expansion ring groove 7 as a second inclined plane matching the first inclined plane. In this way, by providing the first inclined plane and the second inclined plane, it is convenient to press the secondary ring frame 2 into the main ring frame 1.

[0037] A method for making the above conductive ring, comprising a main ring frame 1, a secondary ring frame 2, a mounting ring frame 3, and a conductive fiber 4, comprising the following steps:

[0038] 1) First, the conductive fiber 4 is passed from the front side of the mounting ring frame 3 through the outer circumferential wall and the back side of the mounting ring frame 3 and then returned to the front side of the mounting ring frame 3, so that each conductive fiber 4 located on the end face of the mounting ring frame 3 is parallel to the end face of the mounting ring frame 3, and the conductive fiber 4 passes through the center of the mounting ring frame 3; that is, a conductive fiber 4 is formed.
