Description

Technical Field

[0001] This utility model relates to the field of conductive ring technology, specifically to a potting-connected conductive ring. Background Technology

[0002] As a critical drive device, the performance and reliability of the electric motor are essential for the normal operation of the entire system. However, during operation, motors can encounter the problem of shaft static electricity. Shaft static electricity refers to the electrostatic charge accumulated on the motor shaft due to friction or other reasons. Shaft current flows through the motor bearings or other conductive components, which may cause local overheating, accelerate bearing wear, and threaten the normal operation of the motor. The higher the speed, the faster shaft static electricity is generated. Static electricity can cause electromagnetic interference, reduce the service life of the motor, or even damage the motor. Currently, conductive brushes are used to provide a low-impedance path by contacting the motor shaft, guiding the shaft current to the outside, thereby protecting the bearings and internal components of the motor.

[0003] The conductive brush inside a traditional conductive ring consists of an aluminum tube and a carbon fiber bundle. The aluminum tube and the carbon fiber bundle are fixed together by riveting. The aluminum tube and carbon fiber bundle assembly is then installed in a slot inside the conductive ring. Finally, each slot is riveted to fix the aluminum tube and carbon fiber bundle assembly. However, the above riveting method is cumbersome and complicated, resulting in a decrease in efficiency.

[0004] Therefore, this invention provides a potting-connected conductive ring to solve the above problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a glue-filled connecting conductive ring, which effectively solves the problem that the existing riveting method is relatively cumbersome and the process is relatively complicated.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A potting-type conductive ring includes a conductive ring with a stepped ring fixedly installed at its top end. The top end of the conductive ring has a plurality of mounting grooves evenly distributed. Each mounting groove is located inside the stepped ring. A carbon fiber bundle is installed inside each mounting groove. One end of each carbon fiber bundle is in contact with a motor shaft. Conductive adhesive is provided inside each mounting groove. A fixing member is provided on each carbon fiber bundle.

[0008] Preferably, the conductive ring is provided with slots that communicate with each mounting slot, and one end of each mounting slot is provided with an arc-shaped positioning slot.

[0009] Preferably, the fastener includes a fastening block, each of the fastener slots is equipped with a fastening block, each of the fastening blocks has an arc-shaped opening at its bottom end, and each carbon fiber bundle is disposed in the corresponding arc-shaped opening.

[0010] Preferably, two elastic plates are fixedly installed at the left and right ends of each of the fixed blocks.

[0011] Preferably, each of the card slots is perpendicularly arranged to the corresponding mounting slot, and each of the arc-shaped positioning slots is arranged above the corresponding card slot.

[0012] Preferably, each of the fixing blocks has an external cavity at both its front and rear ends, a semi-circular ring is fixedly installed in each external cavity, and an internal block is fixedly installed on each semi-circular ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This glue-filling method is simpler and easier to operate, effectively improving the stability of the carbon fiber bundle, making it less prone to loosening, effectively preventing dust from entering, improving work efficiency, and enhancing the mechanical properties of the carbon fiber bundle.

[0015] 2. The elastic plate increases the friction with the slot, preventing the carbon fiber bundle from easily detaching from the slot and improving stability. At the same time, the conductive ring can guide the shaft current to the outside, thereby reducing static electricity on the motor shaft, protecting the bearings and internal components of the motor, reducing equipment failures, and extending the service life of the equipment.

[0024] The following reference Figures 1 to 7 The embodiments of this utility model will be described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0025] A type of potting adhesive-bonded conductive ring, such as Figure 1 , Figure 2 , Figure 3 As shown, the device includes a conductive ring 1, with a stepped ring 2 fixedly installed at the top end of the conductive ring 1. The outer diameter of the stepped ring 2 is the same as the outer diameter of the conductive ring 1, and the inner diameter of the stepped ring 2 is larger than the inner diameter of the conductive ring 1. A through shaft hole is opened in the middle of the conductive ring 1. Multiple mounting grooves 3 are evenly opened at the top end of the conductive ring 1. The number of mounting grooves 3 is set as needed. One end of the mounting groove 3 is connected to the shaft hole. Each mounting groove 3 is located inside the stepped ring 2. A carbon fiber bundle 4 is installed inside each mounting groove 3. One end of each carbon fiber bundle 4 is in contact with the motor shaft. Conductive adhesive 5 is provided inside each mounting groove 3. A fixing component is provided on each carbon fiber bundle 4.

[0026] Implementation Method 1: First, impregnate one end of each carbon fiber bundle 4 with adhesive to form a whole. Then, place the adhesive-impregnated end of the carbon fiber bundle 4 into the mounting groove 3 and press the carbon fiber bundle 4 into the mounting groove 3 with appropriate tools. Next, drip conductive adhesive 5 into the mounting groove 3 and make it contact with the carbon fiber bundle 4. Use tools to compact the conductive adhesive 5. After the conductive adhesive 5 solidifies, remove the tools. At this time, the conductive ring 1, carbon fiber bundle 4, and conductive adhesive 5 form a whole. Due to the adhesive injection treatment, the carbon fiber bundle 4 and the conductive ring 1 are more firmly connected. During use, the carbon fiber bundle 4 will not detach from the conductive ring 1. Compared with the riveting method, this adhesive injection method is simpler, improves work efficiency, and enhances the mechanical properties of the carbon fiber bundle 4.

[0027] Next, the shaft hole of the conductive ring 1 is fitted onto the outside of the motor shaft, and the conductive ring 1 is fixed to the outer casing of the motor. One end of the carbon fiber bundle 4 contacts the outer wall of the motor shaft. During the operation of the motor shaft, the static electricity of the shaft is transmitted to the conductive ring 1 through each carbon fiber bundle 4 inside the conductive ring 1. The conductive ring 1 guides the shaft current to the outside, thereby reducing the static electricity of the motor shaft, protecting the bearings and internal components of the motor, and thus improving stability.

[0028] like Figure 4 , Figure 5 As shown, the conductive ring 1 has uniformly formed clip slots 6 that communicate with each mounting slot 3, and each mounting slot 3 has an arc-shaped positioning slot 7 at one end, and the carbon fiber bundle 4 is installed in the arc-shaped positioning slot 7.

[0029] like Figure 5 , Figure 6 As shown, the fastener includes a fastening block 8, and a fastening block 8 is installed in each of the fastening slots 6. Each of the fastening blocks 8 has an arc-shaped opening 9 at its bottom end, and each of the carbon fiber bundles 4 is disposed in the corresponding arc-shaped opening 9. The arc-shaped opening 9 is fastened to the carbon fiber bundle 4.

[0030] like Figure 5 , Figure 6 As shown, two elastic plates 10 are fixedly installed at the left and right ends of each of the fixing blocks 8. The fixing blocks 8 and elastic plates 10 are made of plastic or rubber. Under normal conditions, the elastic plates 10 are flat. Each of the clip slots 6 is perpendicular to the corresponding mounting slot 3. Each of the arc-shaped positioning slots 7 is located above the corresponding clip slot 6 to facilitate the placement of the carbon fiber bundle 4.

[0031] like Figure 6 As shown, each of the fixed blocks 8 has an external cavity 11 at both the front and rear ends, and a semi-circular ring 12 is fixedly installed in each of the external cavities 11. An arc-shaped opening 9 is located below the semi-circular ring 12, and an internal block 13 is fixedly installed on each of the semi-circular rings 12. The other end of the internal block 13 is fixedly connected to the fixed block 8.

[0032] Implementation Method 2: First, impregnate one end of each carbon fiber bundle 4 with adhesive to form a single unit. Then, place the adhesive-impregnated end of the carbon fiber bundle 4 into the mounting groove 3 and press it firmly into the mounting groove 3 using appropriate tools. Next, drip conductive adhesive 5 into the mounting groove 3 and make it contact with the carbon fiber bundle 4. Use tools to compact the conductive adhesive 5. After the conductive adhesive 5 solidifies, remove the tools. At this point, the conductive ring 1, carbon fiber bundle 4, and conductive adhesive 5 form a single unit. Then, clamp the arc-shaped opening 9 onto the carbon fiber bundle 4 and press down on the fixing block 8 to move it. The semi-circular ring 12 and the fixing block 8 gradually install the carbon fiber bundle 4 into the corresponding clamping groove 6. As the fixing block 8 moves downward, the elastic plate 10 bends upward, finally completing the installation of the fixing block 8. Due to the bending state of the elastic plate 10, the friction with the clamping groove 6 is increased, and the carbon fiber bundle 4 will not easily detach from the clamping groove 6, further improving the stability of the carbon fiber bundle 4.

[0033] Next, a protective cover is installed on the side of the conductive ring 1 with screws to seal the carbon fiber bundle 4 and the fixing block 8. The shaft hole of the conductive ring 1 is fitted onto the outside of the motor shaft, and the conductive ring 1 is fixed to the motor housing. One end of the carbon fiber bundle 4 is in contact with the motor shaft. During the operation of the motor shaft, static electricity is transmitted to the conductive ring 1 through each carbon fiber bundle 4. The conductive ring 1 guides the shaft current to the outside, thereby reducing the static electricity of the motor shaft, protecting the bearings and internal components of the motor, reducing the occurrence of equipment failures, and extending the service life of the equipment.
