Description

Technical Field

[0001] The present application relates to the technical field of conductive rings, and in particular to a stable and anti-deformation conductive ring. Background Art

[0002] The voltage on the bearing of the variable frequency motor is caused by the inverter drive, and the generated voltage will be released through the bearing through the current.

[0003] When the motor is changing frequency, the voltage on the motor bearings will increase. During the current release process, as static charge accumulates, the surface of the motor bearings becomes black and covered with grease. The motor bearings are gradually corroded by electricity, and the power of the motor becomes smaller and smaller until the motor is completely damaged. In order to prevent the above-mentioned electrical corrosion phenomenon from occurring, conductive rings need to be added to the motor bearings to release the current on the motor bearings.

[0004] In the prior art, in the patent document with patent publication number CN113178980A, a shaft grounding bearing protection device and a motor are disclosed, including: a device body, the device body is annular, and its side wall is provided with at least one mounting hole, the mounting hole opening direction is a first direction, the first direction is toward the center of the device body, and penetrates the device body radially; conductive fibers, the conductive fibers pass through the mounting holes to be arranged on the device body, and the conductive fibers extend in a direction toward the center of the device body; wherein, when the conductive fibers pass through the mounting holes, the device body is deformed by adjusting the clamping force in the second direction of the mounting holes to achieve clamping of the conductive fibers and the device body, the second direction is perpendicular to the first direction, and in the process of adjusting the clamping force in the second direction of the mounting holes, when the clamping force is applied to the end of the conductive fiber bundle, the conductive fiber bundle will be offset radially relative to the device body, resulting in poor stability of the conductive fiber bundle during installation, thereby affecting the conductive performance of the conductive ring.

[0005] Therefore, there is an urgent need for a stable and anti-deformation conductive ring that can solve the above problems, thereby improving the stability of the conductive fiber bundle during installation and ensuring the conductive performance of the conductive ring. Summary of the invention

[0006] In order to improve the stability of the conductive fiber bundle during the process and ensure the conductive performance of the conductive ring, the present application provides a stable and deformation-resistant conductive ring.

[0007] The present application provides a stable and anti-deformation conductive ring, which adopts the following technical solution: A stable and anti-deformation conductive ring comprises a conductive ring body and a conductive fiber bundle, wherein the conductive ring body comprises an outer fixing frame and an inner fixing frame, wherein the outer fixing frame is detachably mounted on the inner fixing frame, wherein a channel is provided between the outer fixing frame and the inner fixing frame, wherein a fixing strip bent into a ring shape is installed in the channel, wherein the conductive fiber bundle is fixedly mounted on one side of the fixing strip, wherein an elastic sheet is provided on the inner fixing frame, wherein after one side of the fixing strip elastically contacts with the elastic sheet, the other side opposite thereto contacts with the outer fixing frame.

[0008] By adopting the above technical scheme, the conductive fiber bundle is fixedly installed on one side of the fixing strip, and the radial length of the conductive fiber bundle relative to the conductive ring body remains unchanged. A channel is formed between the outer fixing frame and the inner fixing frame, and the fixing strip is bent into a ring shape and placed in the channel. The outer fixing frame and the inner fixing frame are detachably connected to facilitate the installation and disassembly of the fixing strip. An elastic sheet is provided on the inner fixing frame. After the fixing strip is installed on the channel, the elastic sheet contacts the fixing strip and makes the other side of the fixing strip contact the outer fixing frame, thereby limiting the radial displacement of the fixing strip relative to the conductive ring body. Compared with the prior art, this structure avoids the radial displacement of the conductive fiber bundle relative to the conductive ring body, improves the stability of the conductive fiber bundle installation process, and thereby ensures the stability of the overall conductive performance of the conductive ring.

[0009] Optionally, a step is provided on the inner side of the fixing strip, and an abutment portion is protruded from the inner side of the inner fixing frame, and the step abuts against the abutment portion.

[0010] By adopting the above technical solution, the fixing strip is installed between the outer fixing frame and the inner fixing frame, a step is provided on the inner side of the fixing strip, and a resistance portion is provided on the inner side of the inner fixing frame. The fixing strip resists against the inner fixing frame through the resistance portion. When the elastic sheet resists against the fixing strip, the fixing strip resists against the outer fixing frame and the resistance portion of the inner layer, thereby further enhancing the radial limiting effect of the fixing strip relative to the conductive ring body, thereby preventing the conductive fiber bundle from being offset in the radial direction relative to the conductive ring body.

[0011] Optionally, a fixing portion is protruded from one side of the fixing strip, a groove is formed on the conductive ring body, and the fixing portion penetrates into the groove and matches with the groove.

[0012] By adopting the above technical solution, the fixing strip is bent into a ring shape and placed in the channel, and the fixing portion on the fixing strip is inserted into the groove on the conductive ring body and matched with the groove, thereby preventing the fixing strip from being offset in the circumferential direction relative to the conductive ring body, and limiting the fixing strip, thereby preventing the conductive fiber bundle on the fixing strip from being offset in the circumferential direction relative to the conductive ring body.

[0013] Optionally, a clamping groove is formed on the inner fixing frame, and a clamping piece that is clamped and matched with the clamping groove is protruded from one side of the outer fixing frame, and one side of the clamping piece contacts the elastic sheet.

[0014] By adopting the above technical solution, the snap-in groove and the snap-in piece are snap-fitted to realize the detachable connection between the outer fixing frame and the inner fixing frame. After the outer fixing frame is installed on the inner fixing frame, the snap-in piece contacts the elastic sheet on the inner fixing frame, further strengthening the radial limiting effect of the fixing strip relative to the conductive ring body.

[0015] Optionally, a through hole is provided on the fixing portion, a reinforcing member is fixedly installed in the through hole, and the conductive fiber bundle is filled in a gap between the reinforcing member and the through hole.

[0016] By adopting the above technical solution, the reinforcement piece and the conductive fiber bundle are filled in the through hole. The provision of the reinforcement piece strengthens the strength of the conductive fiber bundle, thereby increasing the friction between the conductive fiber bundle and the fixing part, and making it more difficult for the conductive fiber bundle to fall off from the fixing part.

[0017] Optionally, a gap is formed between the ends of the fixing strip after being bent into a ring shape.

[0018] By adopting the above technical solution, a gap is left between the two ends of the fixing strip bent into a ring shape, which facilitates the adjustment of the diameter of the fixing strip and ensures that the axis of the fixing strip is consistent with the axis of the conductive ring body, thereby adapting to conductive ring bodies with different channel diameters. Compared with the prior art, the conductive fiber bundle fixed by this structure has stronger adaptability.

[0019] Optionally, the inner side or the outer side of the fixing strip is recessed to form a deformation groove, and the deformation groove is arranged to penetrate along the axial direction of the fixing strip.

[0020] By adopting the above technical solution, the deformation groove is opened along the axis of the fixing bar. When the diameter of the fixing bar is adjusted to adapt to different channels, the setting of the deformation groove facilitates the bending of the fixing bar and avoids the fixing bar from breaking when bending.

[0021] Optionally, the deformation groove is communicated with the channel, the clamping groove passes through the inner and outer surfaces of the inner fixing frame, and the deformation groove is communicated with the clamping groove.

[0022] By adopting the above technical solution, the clamping groove is opened through the inner fixing frame, and the deformation groove is connected with the channel and the clamping groove, which facilitates the heat inside the conductive ring body to diffuse outward, thereby enhancing the stability of the conductive ring body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The conductive fiber bundle is fixedly installed on one side of the fixing strip, and the length of the conductive fiber bundle in the radial direction relative to the conductive ring body remains unchanged. A channel is formed between the outer fixing frame and the inner fixing frame, and the fixing strip is bent into a ring shape and placed in the channel. The outer fixing frame and the inner fixing frame are detachably connected, which is convenient for the installation and removal of the fixing strip. The inner fixing frame is provided with an elastic sheet. After the fixing strip is installed on the channel, the elastic sheet contacts the fixing strip and makes the other side of the fixing strip contact the outer fixing frame, thereby limiting the displacement of the fixing strip in the radial direction relative to the conductive ring body. Compared with the prior art, this structure avoids the radial displacement of the conductive fiber bundle relative to the conductive ring body, improves the stability of the conductive fiber bundle during the installation process, and thus ensures the stability of the overall conductive performance of the conductive ring; 2. After the fixing strip is installed between the outer fixing frame and the inner fixing frame, a step is provided on the inner side of the fixing strip, and a contact portion is provided on the inner side of the inner fixing frame. The fixing strip contacts the inner fixing frame through the contact portion. Under the action of the elastic sheet contacting the fixing strip, the fixing strip contacts the outer fixing frame and the contact portion of the inner layer, further enhancing the radial limiting effect of the fixing strip relative to the conductive ring body, thereby preventing the conductive fiber bundle from being offset in the radial direction relative to the conductive ring body. 3. The fixing strip is bent into a ring shape and placed in the channel. The fixing portion on the fixing strip is inserted into the groove on the conductive ring body and matched with the groove to prevent the fixing strip from being offset in the circumferential direction relative to the conductive ring body, thereby limiting the fixing strip and preventing the conductive fiber bundle on the fixing strip from being offset in the circumferential direction relative to the conductive ring body.

In this embodiment, the material of the outer fixing frame 3 and the inner fixing frame 4 is copper. A snap-in groove 5 is provided on the inner fixing frame 4. A snap-in piece 6 which is snap-fitted with the snap-in groove 5 is protruded on the inner side of the outer fixing frame 3. The snap-in piece 6 is a protrusion on the outer fixing frame 3.

[0028] refer to Figure 2 A channel 8 for placing a fixing strip 7 is provided between the outer fixing frame 3 and the inner fixing frame 4. The channel 8 is annular and is adapted to the fixing strip 7 bent into a ring shape. The fixing strip 7 is made of a conductive material. In the present embodiment, the material of the fixing strip 7 is copper. Copper has good ductility, which is convenient for bending the fixing strip 7 into a ring shape. A fixing portion 9 is formed on the inner side of the fixing strip 7. The fixing portion 9 is a protrusion on the fixing strip 7. A through hole 10 is provided on the fixing portion 9. The through hole 10 runs through the inner and outer sides of the fixing strip 7. A reinforcing member 11 is provided in the through hole 10.
