Description

Technical Field

[0001] The utility model belongs to the technical field of conductive rings, and in particular relates to a conductive ring. Background Art

[0002] With increasing low-carbon demands, the new energy vehicle industry is rapidly developing. This has significantly increased demand for drive motors, pushing the motor industry to new heights and placing higher demands on motor performance, safety, and service life. In drive motors, speed is primarily regulated by controlling voltage frequency. This speed regulation generates capacitive induction on the motor bearings, creating a common-mode voltage. This discharge can cause pitting and electrolytic corrosion on the bearing surface, damaging the bearings and leading to motor failure, thus impacting overall facility operation.

[0003] Currently, the main components for motor shaft electrocorrosion protection are insulating bearings or conductive rings. The working method of insulating bearings is mainly to block the capacitance generated in the motor bearings, thereby solving the shaft current problem. With the increasing demand for rapid regulation of motor high and low speeds, simple capacitor blocking can no longer solve the shaft current problem. At the same time, the balls in the insulating bearings are prone to wear, have a short service life, and have high maintenance costs. In addition, there is an oil film inside the insulating bearings. The oil film is thin and unstable, which is prone to arcing and creepage, causing the oil film to be destroyed and losing its protective effect. Existing conductive rings are single-layer or double-layer structures. Such conductive rings are prone to conductive fiber shedding. After the conductive fibers are worn, they cannot maintain effective contact with the motor shaft, and the protection effect on the motor bearings is poor. Therefore, for the conductive ring structure, how to effectively install the conductive fibers to prevent them from falling off is a problem that needs to be solved urgently. Utility Model Content

[0024] Example 1

[0025] The present embodiment provides a conductive ring having a simple structure. Compared with the existing single-layer structure or double-layer structure, the number of its parts is greatly reduced, thereby effectively reducing the preparation cost of the conductive ring. In addition, the conductive ring of the present invention is simple to assemble, and its assembly efficiency is greatly improved, thereby effectively improving the production and processing efficiency of the conductive ring and saving labor costs. In addition, it can stably install the conductive fiber 30 and effectively prevent the conductive fiber 30 from falling off.

[0026] Combine Figures 1 to 4 As shown, the conductive ring of this embodiment includes a conductive ring body 10 and a fastener 20. The conductive ring body 10 of this embodiment is provided with a plurality of mounting portions 11. The fastener 20 mounts the conductive fiber 30 on the conductive ring body 10 via the mounting portions 11. The mounting effect is good, and the conductive fiber 30 can be stably mounted, effectively preventing the conductive fiber 30 from falling off on the conductive ring body 10.

[0027] In this embodiment, the mounting portions 11 are used in groups of two, and there are multiple groups of mounting portions 11 distributed at intervals along the circumference of the conductive ring body 10 . Therefore, multiple fasteners 20 can be used on the conductive ring body 10 to respectively mount corresponding conductive fibers 30 .

[0028] Furthermore, a plurality of mounting blocks 40 are provided on the conductive ring body 10 of the present embodiment, and the mounting blocks 40 mount the ends of the conductive fibers 30. The number of the mounting blocks 40 is consistent with that of the mounting portion 11 and they are arranged correspondingly. The mounting blocks 40 of the present embodiment can mount the ends of the conductive fibers 30, which is beneficial to further strengthen the installation of the conductive fibers 30 and improve the installation effect of the conductive fibers 30.

[0029] Specifically, the mounting block 40 is provided with a hole 41 for mounting the end of the conductive fiber 30 .

[0030] Combine Figure 1 、 Figure 3 as well as Figure 4 As shown, the fastener 20 of this embodiment is a conductor. The fastener 20 is installed in the installation portion 11 to install the conductive fiber 30. The fastener 20 includes an embedded state and a tightened state. When the fastener 20 is in the embedded state, the fastener 20 is a door-shaped open-loop structure. When the fastener 20 is in the tightened state, the fastener 20 is a mouth-shaped closed-loop structure. Before the fastener 20 is installed in the installation portion 11, the fastener 20 is in the embedded state. At this time, the fastener 20 is a door-shaped open-loop structure. After the fastener 20 is installed in the installation portion 11, the conductive fiber 30 has been preliminarily positioned. Then the fastener 20 is bent to form a mouth-shaped closed-loop structure. At this time, the fastener 20 firmly fixes the conductive fiber 30 on the conductive ring body 10. The fastener 20 of this embodiment is a sheet-like structure. When the fastener 20 is in the tightened state, the conductive fiber 30 is completely wrapped to achieve positioning of the conductive fiber 30.

[0031] In this embodiment, a tough tail 21 is provided on the fastener 20. When the tough tail 21 is expanded, the fastener 20 is in an embedded state. When the tough tail 21 is closed, the fastener 20 is in a fastened state. The fastener 20 is a manganese steel sheet. The tough tail 21 on the fastener 20 in this embodiment can be bent so that the fastener 20 changes from the embedded state to the fastened state, thereby realizing the installation of the conductive fiber 30.

[0032] In actual use of the conductive ring of this embodiment, the conductive fiber 30 is installed on the conductive ring body 10 through the installation portion 11 using a fastener 20. The fastener 20 includes an embedded state and a fastened state. The state of the fastener 20 is adjusted by the tough tail 21 on the fastener 20, thereby facilitating the installation and removal of the conductive fiber 30 on the conductive ring body 10.

[0033] Example 2

[0034] The difference between this embodiment and the first embodiment is that the conductive ring body 10 is not provided with a mounting block 40, and the conductive fiber 30 is fixed to the conductive ring body 10 by a fastener 20. The fastener 20 is in the form of a sheet and can cover the conductive fiber 30 in the axial and radial directions. When the motor runs at high speed, the conductive fiber 30 is not easy to slide or fall off in the axial and radial directions. The fastener 20 of this embodiment can be any conductive material with certain strength and toughness, such as manganese steel sheet, copper sheet, etc.

[0035] Specifically, when a copper tube is fixed to the outside of the conductive fiber 30, the fastener 20 can be directly wrapped around the outside of the copper tube and fit tightly with the copper tube. When the conductive fiber 30 is directly placed on the conductive ring body 10, the fastener 20 is directly wrapped around the outside of the conductive fiber 30 and has a certain bundling effect on the conductive fiber 30. Therefore, when the fastener 20 is inserted into the mounting hole 11, it has a certain guiding and fixing effect on the conductive fiber 30, so that the ends of the conductive fiber 30 all point to the center of the conductive ring body 10.

[0036] In summary, the conductive ring of this embodiment has a simple structure. Compared with the existing single-layer structure or double-layer structure, its components are greatly reduced, thereby effectively reducing the preparation cost of the conductive ring. In addition, the conductive ring of the present invention is simple to assemble, and its assembly efficiency is greatly improved, thereby effectively improving the production and processing efficiency of the conductive ring and saving labor costs. In addition, it can stably install the conductive fiber 30 and effectively prevent the conductive fiber 30 from falling off.
