Description

Technical Field

[0001] This utility model relates to the field of motor accessories technology, specifically to a weight-reducing conductive ring. Background Technology

[0002] Conductive rings are used in motor components. They are generally composed of a ring body and a carbon brush head. However, existing conductive rings generally use a metal ring body structure, which results in a relatively heavy weight, which does not meet the weight reduction requirements to some extent. In addition, the manufacturing cost of metal rings is relatively high, which is not suitable for the current development trend. Therefore, in order to better adapt to development, conductive rings need to be optimized. Utility Model Content

[0003] This invention proposes a weight-reducing conductive ring, which solves the problems of high cost and relatively large weight of existing conductive rings made of metal.

[0004] The technical solution of this utility model is as follows: A weight-reducing conductive ring includes a support ring and a plurality of carbon brush heads. The inner sidewall of the support ring is provided with a plurality of mounting holes, and the carbon brush heads are disposed in the mounting holes. At least the annular portion of the support ring corresponding to the carbon brush head is a conductive portion, and at least the portion of the support ring other than the portion corresponding to the carbon brush head is a weight-reducing portion.

[0005] The bearing ring is also provided with a dispensing through hole, which corresponds to the mounting hole on the inner sidewall of the bearing ring, and the orientation of the dispensing through hole is perpendicular to the corresponding mounting hole.

[0006] The outer surface of the end of the carbon brush head that is inserted into the mounting hole is threaded.

[0007] The bearing ring includes a conductive metal ring and two plastic rings, with the plastic rings disposed on both sides of the conductive metal ring.

[0008] The bearing ring is configured as a conductive rubber ring, and the conductive rubber ring is an integral structure.

[0009] The carbon brush head includes a carbon fiber inner core and a metal shell, with the carbon fiber inner core disposed inside the metal shell.

[0010] The working principle and beneficial effects of this utility model are as follows: This invention discloses a weight-reducing conductive ring. Multiple carbon brush heads are installed in mounting holes on the inner sidewall of a support ring to form the basic structure of the conductive ring. From the perspective of optimizing the conductive ring, it is necessary to meet its conductivity and weight reduction requirements. Therefore, the structure of the support ring can be optimized in a targeted manner. The improved concept is that the annular part on the support ring corresponding to the carbon brush head is the conductive part, thereby ensuring conductivity. Secondly, the part on the support ring other than the position corresponding to the carbon brush head is the weight-reducing part, thereby reducing the overall weight and reducing the use of metal materials, thus reducing costs and achieving the purpose of optimizing the conductive ring.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0014] like Figures 1-2 As shown, this embodiment proposes a weight-reducing conductive ring, which includes a support ring 1 and a plurality of carbon brush heads 2. The inner sidewall of the support ring 1 is provided with a plurality of mounting holes 3. The carbon brush heads 2 are disposed in the mounting holes 3. The support ring 1 has at least the annular portion corresponding to the carbon brush head 2 as a conductive part, and the support ring 1 has at least the portion other than the portion corresponding to the carbon brush head 2 as a weight-reducing part.

[0015] In this embodiment, a weight-reducing conductive ring is disclosed. Multiple carbon brush heads 2 are installed in mounting holes 3 on the inner sidewall of a support ring 1 to form the basic structure of the conductive ring. From the perspective of optimizing the conductive ring, it is necessary to meet its conductivity and weight reduction requirements. Therefore, the structure of the support ring 1 can be optimized in a targeted manner. The improvement idea is that the annular part on the support ring 1 corresponding to the carbon brush head 2 is the conductive part, thereby ensuring conductivity. Secondly, the part on the support ring 1 other than the position corresponding to the carbon brush head 2 is the weight-reducing part, thereby reducing the overall weight and reducing the use of metal materials, thus reducing costs and achieving the purpose of optimizing the conductive ring.

[0016] The bearing ring 1 is also provided with a dispensing through hole 4, which corresponds to the mounting hole 3 on the inner side wall of the bearing ring 1, and the orientation of the dispensing through hole 4 is perpendicular to the corresponding mounting hole 3.

[0017] In this embodiment, the mounting hole 3 provided on the inner side of the support ring 1 is used for the initial fixation of the carbon brush head 2 by insertion. A dispensing through hole 4 is also provided on the support ring 1. After the carbon brush head 2 is inserted into the mounting hole 3, the part of the carbon brush head 2 that extends into the dispensing through hole 4 is fixed for a second time by dispensing glue.

[0018] The outer surface of the end of the carbon brush head 2 that is inserted into the mounting hole 3 is threaded.

[0019] In this embodiment, the stability of the carbon brush head 2 is further improved. The part of the carbon brush head 2 located in the dispensing through hole 4 is provided with threads to improve the tightness of the connection with the secondary sealing adhesive, so as to prevent the carbon brush head 2 from rotating and falling off.

[0020] The bearing ring 1 includes a conductive metal ring 5 and two plastic rings 6, with the plastic rings 6 disposed on both sides of the conductive metal ring 5.

[0021] Based on the above embodiments, in one possible embodiment, the bearing ring 1 can be configured as a combination of a conductive metal ring 5 and two plastic rings 6, with the two plastic rings 6 located on both sides of the conductive metal ring 5. The conductive metal ring 5 is the conductive part, and the plastic rings 6 are the weight-reducing part, thereby achieving weight reduction while maintaining overall conductivity.

[0022] The bearing ring 1 is configured as a conductive rubber ring 7, which is an integral structure.

[0023] Based on the above embodiments, in another possible embodiment, the bearing ring 1 adopts an integral conductive rubber ring 7. The circular part of the conductive rubber ring 7 corresponding to the carbon brush head 2 can still be a conductive part to meet the conductivity requirement. At the same time, the conductive rubber ring 7 is lighter than the metal ring as a whole, which can also meet the purpose of conductivity and weight reduction.

[0024] The carbon brush head 2 includes a carbon fiber inner core 8 and a metal shell 9, with the carbon fiber inner core 8 disposed inside the metal shell 9.

[0025] In this embodiment, the carbon brush head 2 has a carbon fiber core 8 inside a metal shell 9. The carbon fiber core 8 is wear-resistant, lubricated, and conductive. The metal shell 9 protects and binds the carbon fiber core 8.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
