[0002] A reducer is a device that reduces and transmits high-speed rotation. A gear reducer is a common reducer, which achieves the effect of speed reduction through the transmission between gears at all levels.
[0003] During the working process of a gear reducer, the main shaft and multiple reduction gears inside it rotate, resulting in vibrations generated by the gear reducer during operation.
[0004] Currently, a rubber gasket is set between the gear reducer and external equipment for buffering and shock absorption, so that the gear reducer can achieve a self-protection effect during the working process. However, in order to ensure the distance between the gear reducer and external equipment, the thickness of the rubber gasket is limited. If the thickness of the rubber pad is set too large, the distance between the gear reducer and external equipment will be too large, affecting stability. However, the connecting gasket with a smaller thickness has lower strength and a short service life. For this reason, we propose a self-protection structure of a reducer and the reducer.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] The present utility model provides a self - protection structure for a speed reducer as shown in Figures 1 - 4 , which includes a housing 101 and a strengthening mechanism. A first rubber gasket 102 is provided at the top end of the housing 101. A connection structure is provided at the top end of the housing 101. Through the setting of the first rubber gasket 102, when the output end of the speed reducer is fixed to an external device, the first rubber gasket 102 is located between the housing 101 and the mounting surface of the external device. Thus, when the speed reducer is working, the first rubber gasket 102 can absorb the vibration generated during work, thereby achieving the effect of shock absorption, and enabling the speed reducer to achieve the self - protection effect.
[0024] In a preferred embodiment, the strengthening mechanism is arranged at the bottom end of the first rubber gasket 102. The strengthening mechanism includes a second rubber gasket 202. The top end of the second rubber gasket 202 is fixedly connected to the bottom end of the first rubber gasket 102. An annular groove 201 is opened at the top end of the housing 101. The outer wall of the second rubber gasket 202 is movably inserted into the inner wall of the annular groove 201. A plug - in mechanism is provided at the bottom end of the second rubber gasket 202. By providing the annular groove 201 to accommodate the second rubber gasket 202, the combined thickness of the first rubber gasket 102 and the second rubber gasket 202 is greater than that of the first rubber gasket 102 itself, thereby improving the use strength of the self - protection structure and extending the service life of the self - protection structure. At the same time, through the setting of the annular groove 201, the distance between the housing 101 and the mounting surface of the external device does not change with the thickening of the self - protection structure.
[0025] Among them, the connection structure includes a plurality of connection threaded holes 301. The plurality of connection threaded holes 301 are arranged in an annular array at the top end of the housing 101. A convex structure is provided inside the annular groove 201. When the output end of the speed reducer is connected to an external device, the mounting bolts inserted from the mounting surface of the external device are screwed into the connection threaded holes 301 until the mounting surface of the external device abuts against the first rubber gasket 102, thereby completing the installation of the speed reducer.
[0026] Among them, the convex mechanism includes a plurality of annular protrusions 401. The plurality of annular protrusions 401 are arranged in an annular array inside the annular card slot 201. The annular protrusions 401 are opposite to the connection threaded holes 301 in position. A first card hole 402 is opened at the top end of the second rubber washer 202. The outer wall of the annular protrusion 401 is movably inserted and connected with the inner wall of the first card hole 402. A communication hole 403 is opened at the top end of the first rubber washer 102. The communication hole 403 is opposite to the first card hole 402 in position. The annular protrusion 401 and the housing 101 are integrally arranged, and the depth of the connection threaded hole 301 is greater than the height of the annular protrusion 401, so that the installation bolt is more stable when screwed into the connection threaded hole 301, and the connection part of the installation bolt and the connection threaded hole 301 is not prone to deformation. When the second rubber washer 202 is inserted into the annular card slot 201, at this time, the annular protrusion 401 is also inserted into the first card hole 402, and the first rubber washer 102 can be limited by the first card hole 402 and the annular protrusion 401, so that the first rubber washer 102 will not shift, thereby improving the stability of the use of the first rubber washer 102. Through the arrangement of the communication hole 403, the installation bolt inserted from the installation surface of the external device can stably enter the connection threaded hole 301, ensuring the stability of the installation of the speed reducer.
[0027] Among them, the plugging mechanism includes a plug rod 501. The bottom end of the plug rod 501 is fixedly connected to the bottom end of the inner wall of the annular card slot 201. A jack 502 is opened at the bottom end of the second rubber washer 202. The outer wall of the plug rod 501 is movably inserted and connected with the inner wall of the jack 502. A clamping mechanism is arranged at the top end of the plug rod 501. When the second rubber washer 202 is inserted into the annular card slot 201, and the plug rod 501 is inserted into the jack 502, the second rubber washer 202 can be positioned in the annular card slot 201, improving the stability of the use of the second rubber washer 202.
[0028] Among them, the clamping mechanism includes a chuck 602. The bottom end of the chuck 602 is fixedly connected to the top end of the plug rod 501. A second card hole 601 is opened at the top end of the inner wall of the jack 502. The chuck 602 is clamped inside the second card hole 601. The outer diameter of the chuck 602 is larger than the outer diameter of the plug rod 501. When the plug rod 501 is inserted into the jack 502, the chuck 602 will squeeze the jack 502 in the jack 502 to make it deform until the chuck 602 is clamped into the second card hole 601, and the second rubber washer 202 can be positioned in the annular card slot 201. That is, when the second rubber washer 202 is not subjected to a large external pulling force, the second rubber washer 202 can be stably clamped in the annular card slot 201, thereby improving the stability of the use of the second rubber washer 202.
[0029] The present utility model also provides a speed reducer, including a speed reducer self-protection structure according to any one of the above.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
