Description

Technical Field

[0001] This utility model relates to the field of motor cover technology, specifically an anti-slip bushing cover for a synchronous motor. Background Technology

[0002] Traditional synchronous motor shaft sleeve structures typically employ a single-layer seal or a simple shaft sleeve connection design. This type of design mainly consists of a sleeve fixed to the outside of the shaft sleeve and secured to the motor housing with fasteners. This structure provides only basic support and sealing functions, relying on a single sealing ring or gasket to prevent the ingress of external contaminants. However, during motor operation, the poor sealing performance and anti-slip capability of the shaft sleeve allow dust, moisture, and other external contaminants to easily enter the device, damaging the normal operation of internal motor components. Simultaneously, the single-layer sealing material is prone to wear under long-term rotational friction, leading to seal failure and reducing the device's service life and operational stability.

[0003] Addressing the shortcomings of traditional technologies, existing solutions struggle to effectively prevent slippage and sealing failures during rotation. Due to their anti-contamination design, the intrusion of external contaminants exacerbates component wear and shortens device lifespan. Furthermore, traditional reduction gear sets typically employ direct drive, hindering efficient power transmission. Insufficient isolation and protection of the reduction gear set structure makes transmission components susceptible to contamination, leading to unstable power transmission and impacting motor operational stability.

[0004] In view of this, we have studied and improved the existing problems and provided an anti-slip bushing cover for synchronous motors to solve the current problems. The aim of this technology is to solve the problems and improve the practical value. Utility Model Content

The main motor cover has a transmission box on its surface, and the output gear sleeve is rotatably mounted inside the main motor cover. This design effectively improves the anti-slip and sealing performance of the synchronous motor during operation, extending the service life of the equipment.

[0007] A synchronous motor anti-slip shaft sleeve cover includes: a main motor cover, an output gear sleeve, and a mechanical seal assembly. The main motor cover has a transmission box on its surface. The output gear sleeve is rotatably mounted inside the main motor cover. The top surface of the main motor cover has a sealing shaft cover.

The inner side of the output gear sleeve has a planetary gear set. The inner side of the planetary gear set has an input gear shaft rotatably mounted for connection with the motor rotor. The mechanical seal assembly includes a fixed sleeve seat, a ring sleeve, and a slip ring rotatably mounted inside the fixed sleeve seat. The ring sleeve is fixedly sleeved outside the output shaft. The fixed sleeve seat is fixedly mounted on the top surface of the sealing shaft cover. The surface of the slip ring has several abutment rings that slide against the surface of the ring sleeve. This structure, through the sleeve and fixation of the mechanical seal assembly, effectively improves the anti-slip and sealing effect of the motor, prevents slippage during operation and the entry of external contaminants, and extends the service life of the equipment.

[0011] By adopting the above technical solutions, the meshing of planetary gears and ring gears makes power transmission more uniform, reduces vibration, and improves the smoothness of motor operation and transmission efficiency.

[0012] In a preferred embodiment, the present invention can be further configured such that: the inner side of the ring sleeve is provided with a sealing ring that fits against the surface of the output shaft, and the abutment ring is in interference fit with the surface of the ring sleeve.

[0013] By adopting the above technical solutions, the sealing ring design further enhances the sealing effect, prevents lubricating oil leakage and external contaminants from entering the equipment, and ensures the long-term stable operation of the equipment.

[0014] In a preferred embodiment, the present invention can be further configured such that the abutment ring is a polytetrafluoroethylene component, and a plurality of abutment rings are arranged in a stacked parallel manner.

[0015] Performance: The use of polytetrafluoroethylene provides excellent wear resistance, and the stacked parallel arrangement enhances the sealing effect and anti-slip performance, allowing the equipment to maintain good condition during long-term operation.

[0016] In a preferred embodiment, the present invention can be further configured such that: the outer side of the slip ring is provided with an oil passage located inside the fixed sleeve, and the surface of the fixed sleeve is provided with an oil inlet.

[0017] By adopting the above technical solutions, the oil passage design enables the lubricating oil to flow smoothly, effectively reducing frictional heat and wear, and ensuring the stable and efficient operation of the equipment.

[0018] The beneficial effects achieved by this utility model are as follows:

[0019] 1. In this utility model, by setting up a mechanical seal assembly structure, the mechanical seal assembly can be firmly fitted onto the inner side of the output shaft.

The embodiments described are combined with each other in a non-conflicting manner to form a variety of possible specific applications.

[0031] This embodiment provides an anti-slip shaft sleeve cover for a synchronous motor.

The main motor cover 100 has a transmission box 110 on its surface, and the output gear sleeve 200 is rotatably mounted inside the main motor cover 100. A sealing shaft cover 120 is provided on the top surface of the main motor cover 100. The top end of the output gear sleeve 200 penetrates the surface of the sealing shaft cover 120 and is fixedly mounted on an output shaft 230. The mechanical seal assembly 300 is sleeved inside the output shaft 230 to ensure structural stability and sealing.

[0032] A planetary gear set 210 is provided on the inner side of the output gear sleeve 200, and an input gear shaft 220 for connection with the motor rotor is rotatably mounted on the inner side of the planetary gear set 210. The mechanical seal assembly 300 further includes a fixed sleeve 310, an annular sleeve 320, and a slip ring 330 rotatably mounted on the inner side of the fixed sleeve 310. The annular sleeve 320 is fixedly sleeved on the outer side of the output shaft 230, forming a good anti-slip effect and improving the sealing performance of the device. The fixed sleeve 310 is fixedly mounted on the top surface of the sealing shaft cover 120, enhancing the overall structural stability.

[0033] In addition, the surface of the slip ring 330 is provided with several abutment rings 331 that slide against the surface of the ring sleeve 320.

Furthermore, the design of the sealing ring enhances sealing performance, ensuring the cleanliness of the device's interior and effectively preventing malfunctions caused by contaminants entering.

[0039] In this embodiment, the design of the abutment ring 331 and the slip ring 330 is optimized. Several abutment rings 331 are made of polytetrafluoroethylene (PTFE) and arranged in a stacked parallel configuration, providing excellent wear resistance and anti-slip properties. The slip ring 330 has an oil passage located inside the fixed sleeve seat 310 on its outer side. The fixed sleeve seat 310 has an oil inlet 311 on its surface, allowing for smooth flow of lubricating oil, ensuring effective lubrication during operation, reducing heat generated by friction, and improving the durability of the device.
