[0002] A motor grounding ring is a device used in electrical systems. Its main function is to guide the shaft current through the end cover to the ground, thereby preventing the shaft current from damaging the bearings and related equipment, effectively solving the shaft voltage problem, and preventing the bearings from being damaged by electrolytic corrosion.

[0003] Common motor grounding rings have a relatively simple structure. Typically, the current from the motor shaft flows through the grounding ring, through the casing, and then to the ground. This grounding method has certain drawbacks. In actual use, there is a risk of electric shock due to contact with the casing, resulting in insufficient safety. Therefore, we propose an integrated insulating sheath type motor grounding ring. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: an integrated insulating sheath type motor grounding ring, including a motor housing 1, a connecting mechanism 2 installed inside the motor housing 1 near the front, a motor shaft 101 installed inside the motor housing 1 near the center, and a grounding component 102 sleeved on the outer periphery of the motor housing 1 near the front. The connecting mechanism 2 includes a grounding ring 201, which is sleeved on the outer periphery of the motor shaft 101. A fixing ring 202 is provided on the outer periphery of the grounding ring 201. Support components 203 are installed on the left and right sides and the bottom of the fixing ring 202. Several slots 204 are equidistantly opened at the top of the fixing ring 202. Example

[0035] like Figure 1-4As shown, the grounding assembly 102 includes a grounding rod 1021, with a plug rod 1022 welded to the inner side of the grounding rod 1021 corresponding to the slot 204. An integrated insulating sleeve 1023 is fitted around the grounding rod 1021 and the plug rod 1022. Grounding screws 1024 are threaded through the top ends of both ends of the grounding rod 1021 and its bottom. The integrated insulating sleeve 1023 prevents the grounding rod 1021 and plug rod 1022 from contacting the motor housing 1, and allows the grounding rod 1021 to directly guide the shaft current to the grounding screws 1024 through the plug rod 1022. 24. To improve safety, a cap 1025 is provided at the top of the grounding screw 1024. The cap 1025 is threadedly connected to the integrated insulating sleeve 1023. The cap 1025 prevents accidental contact between the user and the grounding screw 1024, thus improving safety. The grounding ring 201 is made of titanium, and conductive fibers 2011 are installed on its inner side where it contacts the motor shaft 101. The conductive fibers 2011 ensure full-circumferential conductive contact with the surface of the motor shaft 101, facilitating improved shaft current conduction. The fixing ring 202 is... Made of copper, the inner side of the fixing ring 202 is tightly fitted to the grounding ring 201. This tight fit between the fixing ring 202 and the grounding ring 201 allows shaft current to be conducted through the grounding ring 201 to the fixing ring 202, and then discharged through the grounding assembly 102, improving ease of use. The support assembly 203 includes a support rod 2031, which is fixedly connected to the motor housing 1. A clip 2032 is fixedly connected to the inner end of the support rod 2031, located on the periphery of the fixing ring 202. The fixing ring 202 can be adjusted via the support rod 2031. To prevent loosening, the retaining ring 202 is prevented from directly contacting the support rod 2031 by the clip 2032. The clip 2032 is made of rubber and engages with the retaining ring 202. The clip 2032 also insulates the retaining ring 202 from the support rod 2031, improving the insulation effect. The outer periphery of the slot 204 is threaded to the threaded rod 2041 through the insertion rod 1022. By rotating the threaded rod 2041, the insertion rod 1022 and the slot 204 can be fixed to prevent loosening and improve the stability of use.

[0036] The working process of this utility model is as follows: When conducting shaft current through the integrated insulating sheath type motor grounding ring, the shaft current on the motor shaft 101 is first guided to the grounding ring 201 through the close contact between the conductive fiber 2011 and the motor shaft 101. The shaft current is then guided into the fixing ring 202 through the grounding ring 201. The shaft current flows through the slot 204 and the insertion rod 1022 to the grounding rod 1021, and finally to the ground through the grounding screw 1024. Under the action of the clip 2032 and the integrated insulating sheath 1023, the shaft current remains insulated from the motor housing 1 throughout the entire conduction process. Compared with the traditional grounding method, this greatly reduces the risk of electric shock and effectively improves the safety of use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
