[0030] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] With reference to Figures 1-3 The utility model provides an embodiment: a worm and gear speed reducer, including base 1, the upper part height of base 1 is connected with gantry 2, the lower part of the inner wall of gantry 2 is opened left and right and is equipped with the sliding slot 3, the inside sliding connection of sliding slot 3 has the sliding block 4, the opposite side fixed connection of sliding block 4 has the mounting plate 5, the upper part fixed connection of mounting plate 5 has the speed reducer body 6, the middle part of base 1 is evenly fixed connection around and is equipped with telescopic column 16, the outside of telescopic column 16 is equipped with spring no. 2 17, spring no. 2 17 one end is fixedly connected with telescopic column 16, spring no. 2 17 other end is fixedly connected with mounting plate 5, the lower part of mounting plate 5 is equipped with buffer assembly, for the buffer of mounting plate 5, buffer assembly includes the installation slot 7 of the middle part of base 1, the inside both sides of installation slot 7 are fixedly connected with installation rod 8, the outside of installation rod 8 is equipped with spring no. 1 9, the outside sliding connection of installation rod 8 has the sliding plate 10, the middle part fixed connection of sliding plate 10 has the mounting block 11, the both sides fixed connection of mounting block 11 has the mounting shaft 12 mounting plate 5 lower part fixedly connected with connecting block 14, the front side fixed connection of connecting block 14 has the connecting shaft 15, the both sides rotationally connected of connecting shaft 15 outside front and back have connecting plate 13, the side rotationally connected of connecting plate 13 and disconnecting connecting shaft 15 is connected in the outside of mounting shaft 12, spring no. 1 9 one end is fixedly connected with installation rod 8, spring no. 1 9 other end is fixedly connected with sliding plate 10.

[0032] When the worm gear reducer produces vibration during operation, in order to effectively alleviate these vibrations and prevent damage to the structure of the reducer, the system absorbs and weakens the vibration through a series of buffering mechanisms. First, the reducer body 6 exerts a downward force, extruding the connecting block 14 and the spring 17. The movement of the connecting block 14 drives the connecting shaft 15 to move forward along the predetermined path, thereby pulling the connecting plate 13. The connecting plate 13 pushes the mounting block 11 through the mounting shaft 12, and the mounting block 11 drives the sliding plate 10 to slide outside the mounting rod 8. The sliding process of the sliding plate 10 effectively extrudes the spring 9, which provides elastic force to buffer the vibration generated by the reducer body 6. At the same time, the spring 17 also plays a buffering role while further absorbing vibration energy. Through the dual action of the spring 9 and the spring 17, the entire system can smoothly absorb the vibration from the reducer body 6, reducing the impact of vibration on the equipment structure, thereby preventing the reducer structure from loosening or other damage due to excessive vibration. This buffering design not only effectively improves the running stability of the worm gear reducer, but also prolongs the service life of the reducer and its related components, ensuring that the equipment can maintain a low vibration level during long-term operation, thereby improving overall work efficiency and safety.

[0033] With reference to Figures 3-5 The front side of the reducer body 6 is provided with a fixed groove 18, and the inside of the fixed groove 18 is provided with a cooling assembly for cooling the reducer body 6. The cooling assembly includes a heat dissipation fin 19 fixedly connected to the inside upper part of the fixed groove 18. The inside lower part of the fixed groove 18 is fixedly connected with a mounting frame 20. The inside of the mounting frame 20 is fixedly connected with a fixed plate 21. The lower part of the fixed plate 21 is fixedly connected with a motor 22. The output end of the motor 22 is fixedly connected with a rotating shaft 23. The end of the rotating shaft 23 away from the motor 22 is fixedly connected with a fan blade 24. The rotating shaft 23 penetrates through the fixed plate 21.

[0034] In the operation process of the worm gear reducer, in order to ensure its efficient and stable work, timely cooling is crucial, when the reducer needs to be cooled, the heat dissipation fins 19 first play an important role, they are designed to directly dissipate heat from the reducer body 6, the design of the heat dissipation fins 19 optimizes the heat exchange surface area, thereby enhancing the heat dissipation, next, the control system starts the motor 22, so that it starts to run, and then drives the rotating shaft 23 to rotate, the rotation of the rotating shaft 23 directly drives the fan blade 24 to rotate rapidly to form a strong airflow, the function of the fan blade 24 is to blow the surrounding air rapidly to the heat dissipation fins 19, which not only accelerates the heat exchange process between the heat dissipation fins 19 and the air, but also effectively improves the heat dissipation effect, through the mutual cooperation of this system, the worm gear reducer can realize the efficient self-cooling mechanism, this automatic cooling mode not only significantly reduces the temperature inside the reducer, but also effectively prevents potential damage to the equipment caused by overheating, thereby greatly improving the service life and operation efficiency of the worm gear reducer.

[0035] Working principle: when the vibration generated by the operation of the worm gear reducer needs to be buffered, the reducer body 6 exerts a downward force to press the connecting block 14 and the spring 2 17, the connecting block 14 drives the connecting shaft 15 to move, so that the connecting shaft 15 pulls the connecting plate 13, the connecting plate 13 pushes the mounting block 11 through the mounting shaft 12, the mounting block 11 drives the sliding plate 10 to slide outside the mounting rod 8 and press the spring 1 9, the vibration is buffered by the spring 2 17 and the spring 1 9, so that the worm gear reducer can buffer the vibration generated by the operation, prevent the vibration from loosening the structure of the reducer, when the worm gear reducer needs to be cooled, the reducer body 6 is cooled by the heat dissipation fins 19, then the motor 22 is controlled to start and run, driving the rotating shaft 23 to rotate, the rotating shaft 23 drives the fan blade 24 to rotate, the air is blown to the heat dissipation fins 19 by the fan blade 24 to improve the heat dissipation effect, so that the worm gear reducer can be efficiently self-cooled, and the service life of the worm gear reducer is improved.
