Description

Technical Field

[0001] This utility model relates to the field of conductive ring technology, and specifically to a conductive ring with a novel connection structure. Background Technology

[0002] In modern industrial automation and precision equipment, motors are the core power source, and their stability and reliability are of paramount importance. However, during high-speed operation, motors often generate static electricity on the shaft due to factors such as friction and electrical discharge. The higher the speed, the faster the static electricity is generated. If this problem is not properly addressed, it may lead to serious consequences such as electromagnetic interference, reduced motor lifespan, or even motor damage.

[0003] Shaft static electricity refers to the static charge accumulated on the motor shaft due to friction or other reasons. Shaft current flows through the motor bearings or other conductive parts, which may cause local overheating, accelerate bearing wear, and threaten the normal operation of the motor.

[0004] To eliminate static electricity on the shaft, one of the current technical solutions is to use conductive brushes. By contacting the motor shaft, the conductive brushes provide a low-impedance path to guide the shaft current to the outside, thereby protecting the bearings and internal components of the motor.

[0005] Traditional conductive rings contain conductive brushes made of aluminum tubes and carbon fiber bundles. However, during installation, the aluminum tubes and carbon fiber bundles are first fixed together by riveting, and then the aluminum tube and carbon fiber bundle assemblies are installed one by one into the slots inside the conductive ring. Finally, each slot needs to be riveted to fix the aluminum tube and carbon fiber bundle assemblies. This invention provides a conductive ring with a novel connection structure. Utility Model Content

[0031] The following will refer to Figures 1 to 11 The description provides a detailed description of each embodiment of the present invention.

[0032] Example 1, as shown in the appendix Figures 1-11 As shown, a conductive ring with a novel connection structure includes a conductive ring 1. The inner wall of the conductive ring 1 has several circumferentially distributed slots 2. Each slot 2 contains a carbon fiber bundle 3. A connector 4 is installed on the outer side of each carbon fiber bundle 3. The carbon fiber bundle 3 is composed of several carbon fiber filaments, which are fixed into a bundle shape by the connector 4. The carbon fiber bundle 3 is fixedly installed inside the slot 2 by the connector 4. After the carbon fiber bundle 3 is installed inside the slot 2, a cover plate can be installed on the side of the conductive ring 1 with screws to close the slots 2. The conductive ring 1 is then fitted onto the outer side of the motor shaft and fixed to the motor housing. At this time, one end of each carbon fiber bundle 3 extending towards the middle of the conductive ring 1 abuts against the outer wall of the motor shaft. During the operation of the motor shaft, static electricity is transmitted to the conductive ring 1 through the carbon fiber bundles 3 inside the conductive ring 1. The conductive ring 1 guides the shaft current to the outside, thereby reducing static electricity on the motor shaft and protecting the bearings and internal components of the motor.

[0033] As attached Figures 1-2 As shown, the connector 4 is a spirally wound metal wire 5. The metal wire 5 winds several carbon fiber filaments into a carbon fiber bundle 3, which is a metal wire carbon fiber bundle assembly. The metal wire 5 is fixedly installed inside the slot 2. The carbon fiber bundle 3 formed by the metal wire 5 can simplify the structural components, provide better outer protection, and reduce the damage to the carbon fiber filaments caused by the tubular crimping method.

[0034] As attached Figure 1 As shown, the metal wire 5 and the slot 2 are interference-fitted. The outer diameter of the metal wire 5 can be equal to or slightly larger than the width of the slot 2. During installation, a little force is needed to press the metal wire carbon fiber bundle assembly into the slot 2, thereby initially fixing the metal wire carbon fiber bundle assembly and preventing it from falling out of the slot 2 during the installation of subsequent metal wire carbon fiber bundle assemblies. After all the metal wire carbon fiber bundle assemblies are initially installed, they can be further fixed by attaching the attached... Figure 1 The riveting component shown in the figure rivets the two sides of the slot 2 toward the center, thereby squeezing the slot 2 together toward the center, thereby deforming the slot 2 to obtain a locking force on the metal wire carbon fiber bundle assembly, thereby achieving further fixation.

[0035] As attached Figure 3 , Figure 4As shown, the connecting piece 4 is a tin solder layer 6, one end of the carbon fiber bundle 3 is provided with a tin solder layer 6, the tin solder layer 6 fixes several carbon fiber filaments into a carbon fiber bundle 3, and the carbon fiber bundle 3 is welded in the inside of the clamping groove 2 through the tin solder layer 6. The carbon fiber bundle 3 can be quickly fixed in the inside of the clamping groove 2 through tin solder welding, and the fixation is most stable.

[0036] As shown in the accompanying drawings Figures 5-11 As shown, the connecting piece 4 is an aluminum hollow tube 7 and an insert 8, one end of the carbon fiber bundle 3 is sleeved with the aluminum hollow tube 7, and the aluminum hollow tube 7 is riveted with the carbon fiber bundle 3 in the inside thereof into an integrated body, and the insert 8 is fixedly installed at one end of the aluminum hollow tube 7, and the insert 8 is embedded and fixed in the inside of the clamping groove 2. The installation of the carbon fiber bundle 3 can be realized by embedding the insert 8 in the clamping groove 2. At this time, the installation of the carbon fiber bundle 3 is completed, and direct use can be performed. However, in order to further fix, the two sides of the clamping groove 2 can be riveted again, so that the clamping groove 2 is deformed to obtain the locking force of the insert 8.

[0037] As shown in the accompanying drawings Figure 8 、 Figure 9 As shown, the outer side of the aluminum hollow tube 7 is provided with an annular groove 9, the inner wall of the insert 8 is provided with an annular protrusion 10 matched with the annular groove 9, and the insert 8 and the annular protrusion 10 are integrally injection molded on the outer side of the aluminum hollow tube 7, so that the insert 8 cannot fall off from the outer side of the aluminum hollow tube 7.

[0038] As shown in the accompanying drawings Figure 10 、 Figure 11 As shown, the top of the two side surfaces of the clamping groove 2 is respectively provided with a clamping inclined surface 11, the inner walls of the two sides of the clamping groove 2 are respectively provided with a clamping groove 12, and the left and right sides of the insert 8 are respectively integrally connected with a clamping block 13. One end of the clamping block 13 away from the insert 8 is obliquely upwardly arranged and clamped into the inside of the two clamping grooves 12. When installing, the insert 8 only needs to be pressed into the inside of the clamping groove 2, the two clamping inclined surfaces 11 extrude the two clamping blocks 13 to the middle part, when the insert 8 completely enters the inside of the clamping groove 2, the two clamping blocks 13 are reset to the outside and enter the two clamping grooves 12, so as to realize the positioning and fixation of the insert 8.

[0039] The above-mentioned conductive ring can be used in various systems of automobiles, such as power steering, power motor and air conditioner compressor, and the reliability of the motor is very important. The use of the conductive ring can reduce the failure caused by shaft static electricity, and can also be used in the navigation and control system of an airplane or a satellite. The conductive ring can ensure the stable electrical connection between the rotating part and the fixed structure, avoid the interference of shaft static electricity, and improve the safety and operation efficiency of the rotating amusement facilities in the amusement park, such as the Ferris wheel.
