Description

Technical Field

[0001] This utility model relates to the field of motor end cap technology, specifically an insulating end cap with an anti-detachment structure. Background Technology

[0002] In the operating system of motor equipment, the insulating end cover is a key component that ensures the safe and stable operation of the motor, and its performance and reliability are of paramount importance. With the increasing expansion and diversification of motor applications, the technical requirements for insulating end covers are becoming increasingly stringent, leading to the development of insulating end covers with anti-detachment structures. From a structural stability perspective, traditional insulating end covers are prone to loosening at their connection points with other motor components in complex motor operating environments, especially when facing continuous mechanical vibration, impact, and thermal expansion and contraction caused by temperature changes.

[0003] Existing devices primarily place an insulating pad between the motor end cover and the bearing sleeve. Many existing technologies resemble an insulating end cover for electric motors. The structure of CN211791039U includes an insulating end cover body, a bearing sleeve fitted at the center of the insulating end cover body, insulating paper corresponding to the insulating end cover body wrapped around the outer wall of the bearing sleeve, and a rotating bearing installed at the center of the bearing sleeve. An inner bearing end cover and an outer bearing end cover, corresponding to the bearing sleeve and rotating bearing, are respectively installed at the center of the inner and outer walls of the insulating end cover body. This invention effectively prevents bearing electro-corrosion and improves the overall performance of the motor; however, there are still areas for optimization in this device.

[0004] Existing devices mainly assemble insulating end caps by using inner and outer sleeves, which makes some insulating pads prone to falling off due to vibration. At the same time, it is difficult to stably connect some end cap bodies and bearing sleeves with insulating pads in place, reducing the stability and practicality of the device. Therefore, in order to solve the above problems, an insulating end cap with an anti-fall-off structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an insulating end cap with an anti-detachment structure to solve the problems mentioned in the background art. The existing devices mainly use inner and outer sleeves to complete the assembly of the insulating end cap, which makes some insulating pads easy to fall off due to vibration. At the same time, it is difficult to stably connect the end cap body and the bearing sleeve together with the insulating pads in the isolation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an insulating end cap with an anti-detachment structure, comprising an end cap body, an insulating pad disposed inside the end cap body, the main body of the insulating pad being annular in shape, the single-sided cross-section of the main body of the insulating pad being L-shaped, a bearing sleeve disposed on the inner wall of the insulating pad; a sealing ring disposed in the annular groove at the bottom of the bearing sleeve, an anti-detachment mechanism provided on the inner wall of the insulating pad, and an assembly mechanism provided inside the insulating pad.

[0007] Preferably, the anti-fall-off mechanism includes a first anti-slip texture, which is formed on the upper inner wall of the insulating pad, and a second anti-slip texture corresponding to the first anti-slip texture is formed on the upper outer wall of the bearing sleeve.

[0008] Preferably, the bottom outer ring of the insulating pad is provided with a hook edge, and the outer wall of the bearing sleeve is provided with a groove corresponding to the hook edge.

[0009] Preferably, the bottom inner ring of the insulating pad has pins arranged in a ring array, and the inner outer ring of the bearing sleeve has insertion holes corresponding to the pins.

[0010] Preferably, the main structure, first anti-slip texture, hook edge and pin of the insulating pad are integrally molded from SMC material.

[0011] Preferably, the assembly mechanism includes a bolt hole, which is opened inside the pin, and a mounting bolt is inserted into the lower part of the bolt hole. The inner wall of the end cap body has a threaded groove corresponding to the mounting bolt.

[0012] Preferably, the top of the sealing ring is provided with a sealing post corresponding to the insertion hole, and the bottom of the sealing ring is fixedly connected with an outer pull ring strip.

[0013] Preferably, the outer wall of the sealing ring is provided with a limiting ring strip, and the annular groove of the bearing sleeve is provided with a limiting ring groove corresponding to the limiting ring strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the combination of the first and second anti-slip textures, can increase sliding resistance and effectively prevent the insulating pad from sliding up and down. Furthermore, the hooked edge and hooked groove further prevent the insulating pad from falling off. Simultaneously, the insertion pin, which limits the insertion into the socket, prevents the insulating pad from rotating horizontally relative to the outer wall of the bearing sleeve, thus preventing the insulating pad from falling off. This allows the insulating material to be stably fitted onto the bearing sleeve, improving the stability and practicality of the device.

[0015] 2. The main structure, first anti-slip texture, hook edge, and pins of this utility model's insulating pad are integrally molded from SMC material, reducing the number of parts and simplifying assembly. The assembly mechanism facilitates the insulated connection of the end cap body and bearing sleeve. Furthermore, the addition of a sealing ring structure allows the sealing ring to seal and cover the insertion bolts, effectively reducing the risk of shaft current leakage and improving the device's insulation and practicality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 One embodiment provided by this utility model: An insulating end cap with an anti-detachment structure includes an end cap body 11, an insulating pad 12 is disposed inside the end cap body 11, the main body of the insulating pad 12 is circular in shape, the single-sided cross-section of the main body of the insulating pad 12 is L-shaped, a bearing sleeve 13 is disposed on the inner wall of the insulating pad 12, a sealing ring 14 is disposed in the circular groove at the bottom of the bearing sleeve 13, an anti-detachment mechanism 2 is provided on the inner wall of the insulating pad 12, and an assembly mechanism 3 is provided inside the insulating pad 12.

[0020] The anti-detachment mechanism 2 includes a first anti-slip groove 21, which is formed on the upper inner wall of the insulating pad 12. A second anti-slip groove 22, corresponding to the first anti-slip groove 21, is formed on the upper outer wall of the bearing sleeve 13. Through this design, the sliding resistance between the bearing sleeve 13 and the insulating pad 12 can be increased by the first anti-slip groove 21 and the second anti-slip groove 22, thereby effectively preventing the insulating pad 12 from sliding up and down and falling off.

[0021] The bottom outer ring of the insulating pad 12 is provided with a hook edge 23, and the outer wall of the bearing sleeve 13 is provided with a groove 24 corresponding to the hook edge 23. Through this design, the hook edge 23 of the insulating pad 12 can be fitted into the groove 24 of the bearing sleeve 13, effectively improving the stability of the insulating pad 12.

[0022] The bottom inner ring of the insulating pad 12 has pins 25 arranged in a ring, and the inner outer ring of the bearing sleeve 13 has corresponding insertion holes 26. This design allows the pins 25 to be inserted into the insertion holes 26, effectively preventing the insulating pad 12 from rotating horizontally relative to the outer wall of the bearing sleeve 13.

[0023] The main structure of the insulating pad 12, the first anti-slip texture 21, the hook edge 23, and the pin 25 are integrally molded from SMC material. This design effectively reduces the gaps between the insulating pads 12, lowering the risk of axial current leakage through these gaps. The assembly mechanism 3 includes a bolt hole 31 located inside the pin 25. A mounting bolt 32 is inserted into the lower part of the bolt hole 31. The inner wall of the end cap body 11 has a threaded groove 33 corresponding to the mounting bolt 32. This design allows the mounting bolt 32 to pass through the insulating pad 12 and the bearing sleeve 13 and be threaded into the threaded groove 33 of the end cap body 11, facilitating the insulating connection of the end cap body 11 and the bearing sleeve 13 together.

[0024] The top of the sealing ring 14 is provided with a sealing post 41 corresponding to the insertion hole 26, and the bottom of the sealing ring 14 is fixedly connected with an outer pull ring strip 42. This design allows the sealing post 41 to seal and cover the mounting bolt 32 inside the insertion hole 26, while the outer pull ring strip 42 facilitates the removal of the sealing ring 14 from the annular groove. The outer wall of the sealing ring 14 is provided with a limiting ring strip 43, and the annular groove of the bearing sleeve 13 is provided with a limiting ring groove 44 corresponding to the limiting ring strip 43. Through this design, the limiting ring strip 43 can cooperate with the limiting ring groove 44 to limit and position the sealing ring 14 in the annular groove.

[0025] Working principle: When it is necessary to prevent the insulating pad 12 from falling off, the sliding resistance is first increased by the first anti-slip texture 21 and the second anti-slip texture 22, and the hook edge 23 of the insulating pad 12 is fitted into the hook groove 24 of the bearing sleeve 13, thereby further preventing the insulating pad 12 from falling off. At the same time, the pin 25 is inserted into the socket 26 to limit the movement, thereby preventing the insulating pad 12 from rotating horizontally relative to the outer wall of the bearing sleeve 13, thus realizing the anti-falling operation of the insulating pad 12.

[0026] When it is necessary to assemble the insulating pad 12, first insert the mounting bolt 32 into the bolt hole 31 so that the mounting bolt 32 passes through the insulating pad 12 and the bearing sleeve 13. Then, turn the mounting bolt 32 clockwise with an Allen wrench so that the thread of the mounting bolt 32 is inserted into the thread groove 33 of the end cover body 11, which facilitates the insulating connection of the end cover body 11 and the bearing sleeve 13 together, thus realizing the assembly operation of the insulating pad 12. The operation is now complete.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
