Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor vibration reduction technology, specifically to an embedded explosion-proof aluminum shell vibration damping pad for motors. Background Technology
[0002] In industrial production, explosion-proof motors are widely used in flammable and explosive environments due to their excellent safety performance. Because of the complex working environment, motor operation is often accompanied by vibration and noise, affecting the stability and service life of the equipment. Therefore, installing a vibration damping structure between the motor and the mounting base has become an important means of improving the overall performance of the equipment. Traditional vibration damping methods mostly use rubber pads, springs, or composite material gaskets, absorbing vibration energy through elastic deformation.
[0003] Most existing explosion-proof motor vibration damping pads are external structures, requiring additional bolts, clips, and other fasteners for positioning during installation. This not only increases the assembly process but also makes the pads prone to shifting or even falling off due to insecure fastening. Furthermore, traditional vibration damping pads are typically planar, making it difficult to fit well with the bottom contour of the aluminum shell, resulting in a small contact area and uneven force distribution, which affects the damping effect. Especially after long-term operation, due to the cumulative effect of vibration, the vibration damping pads are prone to aging and cracking, thereby reducing the overall protection level and operational safety of the motor. Utility Model Content

[0010] Preferably, there are four shock-absorbing pads evenly distributed in the gap between the built-in support ring and the aluminum shell body, and the shock-absorbing pads are in contact with the inner wall of the aluminum shell body.
[0011] Compared with existing technologies, the advantages of this utility model are: the embedded explosion-proof motor aluminum shell shock absorber has a simple and compact structure, is easy to install, and can achieve a stable connection without additional fasteners, thus improving shock absorption performance and long-term reliability.

[0017] 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.
[0018] Please see Figure 1-4This utility model provides a technical solution: an embedded explosion-proof motor aluminum shell shock absorber, including an aluminum shell body 1. The aluminum shell body 1 has a ring structure and is provided with feet at its bottom. Built-in support rings 2 are provided at both the front and rear edges of the aluminum shell body 1. The built-in support rings 2 are connected to the outer edges of the aluminum shell body 1 by multiple fixing bolts 5. Multiple shock absorber blocks 3 are embedded around the gap formed between the built-in support rings 2 and the aluminum shell body 1. A fitting block 4 is provided on one side of the shock absorber block 3 located on the built-in support ring 2. Several fitting grooves that match the structure of the fitting block 4 are provided around the built-in support ring 2. Each fitting groove of the built-in support ring 2 has a positioning post 7 that penetrates the fitting block 4. This structure provides shock absorber blocks 3 at both the front and rear edges of the aluminum shell body 1. An internal support ring 2 is fixedly installed at the edge using multiple fixing bolts 5, forming a stable basic frame. The shock-absorbing pads 3 are then embedded around the gap between the internal support ring 2 and the aluminum shell body 1. Each shock-absorbing pad 3 is equipped with a fitting block 4 on one side. These fitting blocks 4 are precisely embedded into the fitting grooves on the internal support ring 2, ensuring accurate positioning and stable installation of the shock-absorbing pads 3. Positioning posts 7 penetrate the fitting blocks 4, further enhancing the fixing effect of the shock-absorbing pads 3. This allows the entire structure to achieve a stable connection without additional fasteners. This structure not only simplifies the assembly process but also avoids the problems of displacement or detachment caused by loose fastening in traditional external shock-absorbing pads. Furthermore, the shock-absorbing pads 3 fit tightly against the inner wall of the aluminum shell body 1, increasing the contact area and... To ensure uniform stress distribution, the vibration energy generated during motor operation is effectively absorbed and dispersed, reducing the risk of aging and cracking of the damping pads due to long-term vibration accumulation. This improves the overall vibration damping performance and operational stability of the explosion-proof motor, solving the problems of complex installation, insecure fixing, small contact area, uneven stress, and poor long-term reliability in existing technologies. The interlocking block 4 has a through hole that matches the structure of the positioning post 7, and a convex ring 9 is welded and fixed at the outer edge of the through hole of the interlocking block 4. A positioning pin 8 is inserted between the convex ring 9 and the outer end of the positioning post 7. This structure allows the positioning pin 8 to pass through the convex ring 9 and the outer end of the positioning post 7 in sequence, making the connection between the interlocking block 4 and the built-in support ring 2 more secure and stable. This multi-point linkage locking mechanism effectively prevents the shock-absorbing pad 3 from loosening or shifting during operation. Both sides of the convex ring 9 are equipped with reinforcing members 10 fixed to the outside of the interlocking block 4 by screws, and both ends of the positioning pin 8 are also embedded inside the reinforcing members 10. With this structure, after the positioning pin 8 passes through the convex ring 9 and the positioning post 7, the reinforcing members 10 are fastened to the interlocking block 4 by screws, further pressing and covering the ends of the positioning pin 8, enhancing the overall connection rigidity and vibration resistance, and preventing loosening or detachment due to long-term vibration. This effectively improves the stability and durability of the connection between the shock-absorbing pad 3 and the built-in support ring 2. The middle part of the reinforcing member 10 has an arc-shaped structure, and an elastic pad is bonded and fixed to the inner wall of the arc-shaped structure in the middle of the reinforcing member 10.The middle part of the reinforcement component 10 is used to form a close contact with the outer wall of the corresponding positioning pin 8, and the elastic pad is in close contact with the surface of the positioning pin 8 to generate a certain preload, further improving the frictional resistance and shock absorption effect of the connection part. Several mating screw rings 6 are welded and fixed around the outer wall of the front and rear ends of the aluminum shell body 1, and the positions of the mating screw rings 6 and the fixing bolts 5 correspond one-to-one. The fixing bolts 5 pass through the threaded ring on the inner support ring 2 and screw into the corresponding mating screw rings 6, so that the inner support ring 2 and the aluminum shell body 1 form a stable and reliable connection structure, ensuring that the force of each connection point is uniform and the assembly is convenient. There are four shock-absorbing pads 3 in total, and they are all The damping pads 3 are evenly distributed in the gap between the built-in support ring 2 and the aluminum shell body 1, and are in close contact with the inner wall of the aluminum shell body 1. These damping pads 3 are made of existing high-polymer elastic rubber material, possessing excellent damping and wear resistance, effectively absorbing the vibration energy generated during motor operation. They also exhibit excellent aging resistance and structural stability, making them suitable for various complex working conditions. Specifically, when the motor vibrates, the tight contact between the damping pads 3 and the inner wall of the aluminum shell body 1 achieves uniform absorption and dispersion of vibration energy. Simultaneously, the built-in support ring 2 provides a stable support foundation for the damping pads 3, preventing displacement or deformation due to uneven stress.
[0019] Working principle: When using this embedded explosion-proof motor aluminum shell shock absorber, firstly, place the built-in support ring 2 at the front and rear edges inside the aluminum shell body 1, and tighten it one by one with the corresponding fixing bolts 5 and mating screw rings 6. After the built-in support ring 2 is installed, an annular gap is formed between it and the aluminum shell body 1. Then, the shock absorber block 3 with the fitting block 4 is embedded into the gap between the built-in support ring 2 and the aluminum shell body 1 in sequence, so that the fitting block 4 is accurately inserted into the fitting groove on the built-in support ring 2. Next, the positioning pin 7 is passed through the through hole on the fitting block 4 in sequence. After the initial positioning is completed, the positioning pin 8 is inserted between the convex ring 9 and the outer end of the positioning pin 7 to achieve further locking. At the same time, when the positioning pin 8 is inserted, both ends will be embedded into the interior of the reinforcement part 10. The reinforcement part 10 covers and presses the two ends of the positioning pin 8 to ensure that the connection is firm and reliable. In this way, the four shock absorber blocks 3 are evenly distributed in the gap and fit against the inner wall of the aluminum shell body 1, thus completing the assembly process of a series of tasks.
[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
