Description

Technical Field

[0001] This application belongs to the field of conductive ring manufacturing technology, specifically a conductive ring. Background Technology

[0002] With increasing low-carbon requirements, the new energy vehicle industry is developing rapidly. This has led to a significant increase in demand for drive motors, propelling the motor industry to new heights and placing higher demands on motor performance, safety, and lifespan. In drive motors, the motor speed is primarily controlled by regulating the voltage frequency. When adjusting the speed, capacitive induction occurs on the motor's output shaft, generating a common-mode voltage. This voltage discharges on the output shaft, causing pitting and electrolytic corrosion spots, damaging the output shaft and leading to motor failure, thus affecting the operation of the entire system. Therefore, protection of the motor's output shaft is necessary.

[0003] Currently, the main components for protecting the output shaft of motors from electrical erosion are insulating bearings and conductive rings.

[0004] Currently, when manufacturing conductive rings, the process of radially arranging several conductive fibers on the inner wall of the ring body requires arranging each conductive fiber on the inner wall of the ring body and then fixing each conductive fiber in place. Since each conductive fiber is relatively small, positioning it is quite complicated. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies by using a mounting ring frame. This allows conductive fibers to be wound around the mounting ring frame and then cut after the mounting ring frame is fixed to the main ring frame and the secondary ring frame. This eliminates the need for positioning each conductive fiber, thus saving time in installing conductive fibers and solving the problem of cumbersome conductive fiber positioning in traditional manufacturing methods.

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

[0007] A conductive ring includes a main ring frame, a secondary ring frame, a mounting ring frame, and conductive fibers. The secondary ring frame is coaxially fixed to the main ring frame, and the mounting ring frame is coaxially located between the main ring frame and the secondary ring frame. The mounting ring frame has a plurality of conductive fibers evenly arranged radially around the center of the mounting ring frame, pointing towards the center of the mounting ring frame.

[0008] Preferably, the outer circumference of the mounting ring frame is provided with a plurality of notches evenly distributed around the center of the mounting ring frame, the two ends of the conductive fiber are located at the notches, and the two ends of each conductive fiber point to the center of the mounting ring frame.

[0009] Preferably, one side of the inner circumferential surface of the main ring frame is coaxially provided with an annular convex ring, and the inner diameter of the secondary ring frame is smaller than the inner diameter of the main ring frame.

[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, one side of the inner circumferential surface of the main ring frame, which is opposite to the annular convex ring, is coaxially provided with an expansion ring groove, the inner diameter of the expansion ring groove is greater 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 the two end surfaces of the mounting ring frame.

[0014] Preferably, the side wall of the expansion ring groove, which is opposite to the center of the expansion ring groove, is a first inclined surface in projection on a parallel to the axis of the expansion ring groove, and the outer circumferential wall of the secondary ring frame is a second inclined surface matched with the first inclined surface in projection on the parallel to the axis of the expansion ring groove.

[0015] Compared with the prior art, the application has the following beneficial effects:

[0016] The application sets the mounting ring frame, so that the positioning step for each conductive fiber is omitted by winding the conductive fiber on the mounting ring frame and then cutting after the mounting ring frame, the main ring frame and the secondary ring frame are fixed, thereby saving the time for installing the conductive fiber and solving the problem of complicated positioning of the conductive fiber in the traditional manufacturing method.

[0023] As shown in Figures 1-5 Fig. 1, 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 with 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 a plurality of conductive fibers 4 are evenly radially arranged on the mounting ring frame 3 around the center of the mounting ring frame 3 and pointing to the center of the mounting ring frame 3.

[0024] In this embodiment, when in use, the conductive fibers 4 are first wound on the mounting ring frame 3 in a manner that the conductive fibers 4 are parallel to the end face of the mounting ring frame 3 and pass 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 secondary ring frame 2 is coaxially placed on the mounting ring frame 3, so that the main ring frame 1 and the secondary ring frame 2 clamp the mounting ring frame 3, and then the main ring frame 1 and the secondary ring frame 2 are fixed together, thereby fixing the main ring frame 1, the secondary ring frame 2, and the mounting ring frame 3 together, and then the conductive fibers 4 inside the mounting ring frame 3 are cut off by shearing, and after shearing, the end portions of all the conductive fibers 4 pointing to 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 diameters of the main ring frame 1, the secondary ring frame 2, and the mounting ring frame 3, and the radius of the virtual circle is greater than 0. In this way, a conductive ring is obtained, and the manufacturing method is relatively simple, so that positioning and limiting of each conductive fiber 4 are not required.

[0025] As a preferred manner, 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 each conductive fiber 4 are located at the notches 5 and point to the center of the mounting ring frame 3. By arranging the notches 5, it is convenient to wind the 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.

[0026] As a preferred manner, a ring-shaped convex ring 6 is coaxially arranged 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 arranging the convex ring 6, it is convenient to make the side of the convex ring 6 facing the secondary ring frame 2 clamp the mounting ring frame 3 and the conductive fibers 4 together with the secondary ring frame 2.

[0027] As a preferred way, the outer diameter of the secondary ring frame 2 is equal to the inner diameter of the primary ring frame 1. After such an arrangement, the secondary ring frame 2 can be embedded into the primary ring frame 1, and then the secondary ring frame 2 and the convex ring 6 limit the installation ring frame 3, thereby preventing the installation ring frame 3 from falling off the end surface of the primary ring frame 1. In actual use, the secondary ring frame 2 is embedded into the primary ring frame 1, and the secondary ring frame 2 and the primary ring frame 1 are in interference fit, and the secondary ring frame 2 is pressed into the primary ring frame 1 by press riveting.

[0028] As a preferred way, the inner diameter of the secondary ring frame 2 is equal to the inner diameter of the annular convex ring 6. After such an arrangement, the inner diameters of the upper and lower ends of the whole composed of the secondary ring frame 2 and the primary ring frame 1 are equal, which avoids the whole composed of the secondary ring frame 2 and the primary ring frame 1 from shaking after being set on the output shaft of the motor.

[0029] As a preferred way, the inner circumferential surface of the primary ring frame 1 opposite to the annular convex ring 6 is coaxially provided with an expansion ring groove 7, the inner diameter of the expansion ring groove 7 is greater than the inner diameter of the primary ring frame 1, and the outer diameter of the secondary ring frame 2 is equal to the outer diameter of the expansion ring groove 7. Through the design of the expansion groove 7, it is prevented that the secondary ring frame 2 is extruded to the conductive fiber 4 and the installation ring frame 3 during the process of pressing the secondary ring frame 2 into the primary ring frame 1.

[0030] As a preferred way, the distance from the expansion ring groove 7 to the annular convex ring 6 is greater than the distance between the two end surfaces of the installation ring frame 3. After such a design, there is still enough gap to accommodate the conductive fiber 4 after the installation ring frame 3 is installed between the primary ring frame 1 and the secondary ring frame 2.

[0031] As a preferred way, as shown in Figure 4 the side wall of the expansion ring groove 7 opposite to the center of the expansion ring groove 7 is a first inclined surface, and the projection of the outer circumferential wall of the secondary ring frame 2 on the parallel to the axis of the expansion ring groove 7 is a second inclined surface matched with the first inclined surface. In this way, by setting the first inclined surface and the second inclined surface, the secondary ring frame 2 is facilitated to be pressed into the primary ring frame 1.
