Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a flexible protective ring and a motor. Background Technology

[0002] To prevent electro-corrosion of motor bearings from affecting their performance and lifespan, a protective ring is typically installed on the motor shaft. The protective ring grounds the shaft voltage generated on the motor shaft, preventing electro-corrosion of the bearings. Specifically, the protective ring contacts the outer circumferential surface of the motor shaft through conductive fiber bundles to conduct current away from the shaft. For example, patent CN221486157U discloses a protective ring including a receiving ring and a cover plate, with multiple conductive fiber bundles arranged circumferentially around the ring body, and each conductive fiber bundle extending radially along the ring body.

[0003] However, existing protective rings have a relatively complex structure, and the ring body is made of rigid material. When assembling them into a motor, either additional fasteners are required, or the motor structure must be modified, such as by creating slots, to accommodate the protective ring. This results in poor adaptability and high installation costs for this type of protective ring. Utility Model Content

[0004] The purpose of this invention is to provide a flexible protective ring and a motor to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model provides a flexible protective ring, comprising:

[0006] Flexible conductive fiber ring and two flexible conductive rings;

[0007] The flexible conductive fiber ring is partially sandwiched between two flexible conductive rings, with a portion of the ring exposed outside the central hole of the two flexible conductive rings; and

[0008] The flexible conductive fiber ring has an axle hole on the ring body exposed above the central hole.

[0009] In one embodiment of this application, an adhesive layer is provided between the flexible conductive fiber ring and the flexible conductive ring.

[0010] In one embodiment of this application, the flexible conductive ring is a metal mesh.

[0011] In one embodiment of this application, the flexible conductive ring is a conductive fabric tape.

[0012] In one embodiment of this application, the flexible conductive ring is a metal foil.

[0013] In one embodiment of this application, the flexible conductive fiber ring is carbon fiber cloth.

[0014] Accordingly, this application provides an electric motor, including: a motor shaft, and a flexible protective ring as described above sleeved on the motor shaft.

[0015] In one embodiment of this application, the motor further includes:

[0016] The bearing is mounted on the motor shaft;

[0017] End cap, which has a bearing housing for accommodating the bearing; wherein

[0018] The flexible protective ring is disposed between the bearing and the end cap.

[0019] The beneficial effects of this utility model are that, unlike the prior art, the flexible protective ring of this utility model includes: a flexible conductive fiber ring and two flexible conductive rings; a portion of the flexible conductive fiber ring is sandwiched between the two flexible conductive rings, and a portion of the ring is exposed in the central hole of the two flexible conductive rings; and a shaft hole is formed on the portion of the flexible conductive fiber ring exposed in the central hole. By making the protective ring a flexible material, it can be directly sleeved on the motor shaft. When installed on the motor, it can be, but is not limited to, directly clamped into the existing structure of the motor, without the need for additional fasteners or additional mounting structures, thus exhibiting good adaptability and low installation cost.

[0027] Flexible conductive fiber ring 1, shaft hole 11, flexible conductive ring 2, center hole 21, flexible protective ring 100, motor shaft 200, bearing 300, end cover 400, bearing chamber 410. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See Figure 1 and Figure 2 In one embodiment of this application, the flexible protective ring includes: a flexible conductive fiber ring 1 and two flexible conductive rings 2; a portion of the flexible conductive fiber ring 1 is sandwiched between the two flexible conductive rings 2, and a portion of the ring is exposed in the central hole 21 of the two flexible conductive rings 2; and a shaft hole 11 is provided on the ring of the flexible conductive fiber ring 1 exposed in the central hole 21.

[0030] In this embodiment, preferably, an adhesive layer is provided between the flexible conductive fiber ring 1 and the flexible conductive ring 2, and the two flexible conductive rings 2 can be attached to the two end faces of the flexible conductive fiber ring 1 by means of adhesive. The adhesive can be a conductive adhesive.

[0031] In this embodiment, preferably, the flexible conductive ring 2 is a metal mesh. For example, it can be a commercially available metal shielding mesh.

[0032] In this embodiment, preferably, the flexible conductive ring 2 is a metal foil, such as copper foil or aluminum foil.

[0033] More preferably, the flexible conductive ring 2 can be a conductive fabric tape.

[0034] Conductive fabric tape can be made from commercially available materials. For example, existing conductive fabric tape can be made by first electroplating nickel onto polyester fiber, then plating a highly conductive copper layer on top of the nickel, and finally electroplating an anti-oxidation and anti-corrosion nickel layer on top of the copper layer. The combination of copper and nickel provides conductivity. Conductive fabric tape is suitable for various electronic and electrical products such as computers, mobile phones, wires and cables.

[0035] Preferably, the flexible conductive fiber ring 1 is made of carbon fiber cloth. Carbon fiber cloth has conductive properties and is easy to cut and process.

[0036] In this embodiment, the flexible conductive fiber ring 1 has a shaft hole 11. Because it is made of flexible material, the shaft hole 11 can be adapted to motor shafts of different sizes.

[0037] Accordingly, in one embodiment of this application, an electric motor is provided, which includes: a motor shaft 200, and a flexible protective ring 100 as described above sleeved on the motor shaft 200.

[0038] In this embodiment, the flexible protective ring 100 can be fitted onto the motor shaft 200 through the shaft hole 11 and then clamped within the existing internal structure of the motor, without the need for additional fasteners or other specially designed fixing structures. For example, it can be clamped between the bearing and the end cover.

[0039] Specifically, the motor further includes: a bearing 300 disposed on the motor shaft 200; an end cover 400 having a bearing chamber 410 for accommodating the bearing 300; wherein the flexible protective ring 100 is disposed between the bearing 300 and the end cover 400.

[0040] In summary, the flexible protective ring of this utility model is made of flexible material and can be directly sleeved on the motor shaft. When installed on the motor, it can be, but is not limited to, directly clamped into the existing structure of the motor without additional fasteners or other installation structures. It has good adaptability and low installation cost. Because the flexible protective ring is made of flexible material, it has good contact with the motor shaft, bearings, end caps and other structures.

[0041] All the devices (parts whose specific structures are not specified) selected in this application are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
