Description

Technical Field

[0001] This utility model relates to the field of motor accessories, and in particular to a motor cover sealing gasket. Background Technology

[0002] Motor parts refer to the original parts that assemble motors at the motor manufacturer, as well as the parts that are replaced due to damage caused by improper use or wear. Among them, the motor cover is an important component of the motor, mainly used to protect the internal mechanical parts of the motor, while also serving to fix and support them. The sealing gasket of the motor cover can effectively improve the motor's protective performance, prevent liquids, dust and other impurities from entering the motor, and ensure the stable and reliable operation of the motor.

[0003] As a widely used power device in industrial production and daily life, the stability and reliability of motor operation are of paramount importance. The sealing performance between the motor cover and the motor body directly affects the protection level and service life of the motor. Currently, common motor cover gaskets have the following problems: the gasket lacks a precise positioning structure during installation, which easily leads to misalignment between the gasket and the cover and motor body, greatly reducing the sealing effect. External impurities can easily enter the motor, accelerating the wear of motor parts. To address these issues, we propose a motor cover gasket that solves the above problems. Utility Model Content

[0010] In a further embodiment, the anti-stick layer is made of polytetrafluoroethylene coating, and the main sealing gasket is made of high-performance rubber material.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device achieves precise positioning of the main sealing gasket and the cover plate body through the cooperation of the positioning protrusion cylinder, the round insert rod, and the positioning port in the positioning assembly.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] 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.

[0017] Please see Figures 1-5In this utility model, a motor cover sealing gasket includes a cover body 1 and a main sealing gasket 3. A positioning component 4 is fixedly connected to the outer surface of the main sealing gasket 3. An anti-stick layer 7 is provided on the outer surface of the main sealing gasket 3. An elastic buffer layer 9 is provided inside the main sealing gasket 3. The positioning component 4 includes a plurality of positioning protrusions 401 fixedly connected to the outer surface of the main sealing gasket 3. A positioning opening 403 corresponding to the positioning protrusions 401 is opened on the outer surface of the main sealing gasket 3. A round insert 402 corresponding to the positioning protrusions 401 is fixedly connected to the outer surface of the cover body 1. The anti-stick layer 7 is made of polytetrafluoroethylene (PTFE). The fluoroethylene coating, made of polytetrafluoroethylene, has an extremely low coefficient of surface friction and good chemical stability, which can prevent the gasket from sticking to the motor components during installation and disassembly, making it easy to operate. The main sealing gasket 3 is made of high-performance rubber material, such as fluororubber, silicone rubber or EPDM rubber, which has good wear resistance, aging resistance and chemical corrosion resistance, and can adapt to different working environments. It forms the core structure for positioning, anti-sticking and buffering of the motor cover gasket. The positioning component 4 enables precise installation, the anti-sticking layer 7 is easy to disassemble, and the elastic buffer layer 9 improves the shock absorption performance. The multi-structure synergy improves the overall performance of the sealing gasket.

[0018] The elastic buffer layer 9 is located inside the main sealing gasket 3. It adopts a honeycomb structure. The honeycomb structure of the elastic buffer layer 9 has high elasticity and good energy absorption capacity. When the motor vibrates during operation, the deformation of the honeycomb holes effectively disperses the vibration energy and reduces the intensity of vibration transmitted to the cover plate. The outer surface of the cover plate body 1 has multiple main openings 2, and the outer surface of the main sealing gasket 3 has multiple secondary openings 6. Each secondary opening 6 is equipped with a sealing ring 10. The main openings 2, secondary openings 6 and sealing rings 10 cooperate to form a multi-layer sealing structure. When the cover plate body 1 is fastened to the motor body, the sealing ring 10 is deformed under pressure and fills the gaps, effectively preventing liquid and gas leakage and the entry of external impurities.

[0019] The outer surface of the main sealing gasket 3 is chamfered 5. The chamfer 5 design makes the edge of the sealing gasket smoother, reducing frictional resistance with the cover plate and the motor body during installation, and facilitating installation. At the same time, the chamfer 5 can prevent impurities from accumulating at the edge of the sealing gasket, avoiding affecting the sealing effect. The outer surface of the main sealing gasket 3 is provided with multiple grooves 8, and the grooves 8 are wavy. The wavy grooves 8 increase the contact area between the sealing gasket and the contact surface. When the cover plate is tightened, the grooves 8 deform and fill the tiny gaps, enhancing the sealing effect. It can also increase the friction between the main sealing gasket 3 and the cover plate body 1 and the motor body, preventing the main sealing gasket 3 from shifting.

[0020] The working principle of this utility model is as follows: When installing the sealing gasket, a positioning groove that matches the positioning protrusion 401 is pre-cut on the motor surface. The round insert 402 on the cover plate body 1 is aligned with the positioning protrusion 401 of the main sealing gasket 3 and inserted. Then, the positioning protrusion 401 is embedded into the positioning groove pre-cut on the motor that matches the positioning protrusion 401. The main sealing gasket 3 and the cover plate body 1 can be accurately installed in a short time. Compared with the traditional non-positioning structure, the installation efficiency is greatly improved. Then, the cover plate body 1, the main sealing gasket 3 and the motor can be fastened together with bolts. The wavy groove 8 increases the contact area between the sealing gasket and the contact surface. The anti-stick layer 7 has extremely low surface energy and friction coefficient, which makes the sealing gasket easily detach from the cover plate and the machine body when disassembling. Moreover, the honeycomb structure elastic buffer layer 9 has high elasticity and good energy absorption capacity. When the motor vibrates during operation, the deformation of the honeycomb holes effectively disperses the vibration energy and reduces the intensity of vibration transmitted to the cover plate. It can absorb pressure and vibration, ensuring that the main sealing gasket 3 and the motor components fit tightly and achieve a good sealing effect.
