In order to enhance the heat dissipation performance of the reducer, the existing technology will add an air cooling structure to the outside of the reducer to achieve better heat dissipation performance by increasing the air flow rate on the reducer surface. However, when the reducer is used in a working environment with a lot of smoke and dust, the air cooling structure is affected by the smoke and dust and needs to be cleaned more frequently. The existing air cooling structure is not easy to disassemble after installation, which makes it inconvenient to perform maintenance operations on the reducer during use.

[0003] In view of the above problems, the present invention makes improvements. Utility Model Content

[0023] The following is a combination of the appended examples of the present invention Figure 1-7 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] As shown in the figure, a high-speed reducer includes a body 1, the lower end of the body 1 is connected to a mounting base 2, the mounting base 2 is provided with an air guide cover 3 covering the body 1 and having an inverted U-shaped cross-section, the air guide cover 3 has a front port and a rear port that are connected, and a connecting foot 31 with an inverted T-shaped cross-section is formed at the lower end of the air guide cover 3, the mounting base 2 is provided with a connecting groove 22 with an inverted T-shaped cross-section that matches the connecting foot 31, the connecting foot 31 is inserted into the connecting groove 22 to connect the air guide cover 3 to the mounting base 2, the front port of the air guide cover 3 is connected to a mounting plate 4, a plurality of air inlets 41 are provided on the mounting plate 4, and a plurality of cooling fans 5 aligned one by one with the air inlets 41 are provided on the inner side of the mounting plate 4.

[0025] Specifically, the air guide cover 3 is limited on the mounting base 2: a connecting platform 21 is formed on the mounting base 2, the connecting groove 22 is arranged on the upper end surface of the connecting platform 21 and passes through the connecting platform 21 front to back, a limiting foot 42 is formed at the lower end of the mounting plate 4, and a first elastic plate 6 is fixedly connected to the side of the air guide cover 3, and a first limiting protrusion 61 is formed on the first elastic plate 6. When the connecting foot 31 is inserted into the connecting groove 22 so that the limiting foot 42 is against the front end of the connecting platform 21, the first limiting protrusion 61 is stuck on the rear end of the connecting platform 21.

[0026] In the above embodiment, the air guide cover 3 is connected to the mounting base 2 by plugging the connecting foot 31 into the connecting groove 22 and covers the body 1 inside it. The cooling fan 5 arranged on the mounting plate 4 is located in the front port of the air guide cover 3. When the reducer passes through, the cooling fan 5 works to draw the external air into the air guide cover 3 through the air inlet 41, so that a fast-flowing airflow is generated in the air guide cover 3, thereby taking away the heat generated by the reducer and the body 1 when the reducer is working, achieving a better heat dissipation effect and ensuring the stability of the reducer when working. When it is necessary to clean the air-cooling structure composed of the air guide cover 3, the mounting plate 4 and the cooling fan 5, the air guide cover 3 is pushed to drive the connecting foot 31 to slide in the connecting groove 22 so that the connecting foot 31 is withdrawn from the connecting groove 22 , the air guide cover 3 can be removed from the mounting base 2, making it convenient to clean the air guide cover 3, the air inlet 41 and the cooling fan 5. The operation is very simple and convenient. When the air guide cover 3 is installed on the mounting base, the limiting feet 42 and the first limiting protrusion 61 are abutted against the front and rear ends of the connecting platform 21, and the sliding of the connecting feet 31 in the connecting groove 22 is limited, which also limits the relative displacement between the air guide cover 3 and the mounting base 2, so that the air guide cover 3 can be more firmly connected to the mounting base 2 to dissipate heat for the machine body 1. When the air guide cover 3 needs to be disassembled for cleaning, the first elastic plate 6 is moved to make the first limiting protrusion 61 leave the position abutting against the end of the connecting platform 21, and the air guide cover 3 can be pushed forward to make the connecting feet 31 slide out of the connecting groove 22.

[0027] Preferably, the mounting plate 4 is connected to the structure on the front port of the air guide cover 3: the inner side edge of the mounting plate 4 is formed with an arc-shaped first plug-in plate 43 and a second plug-in plate 44, a plug-in slot 45 matching the air guide cover 3 is formed between the first plug-in plate 43 and the second plug-in plate 44, a plurality of second elastic plates 7 are fixedly connected to the outer side of the first plug-in plate 43, a second limiting protrusion 71 is formed on the inner side of the second elastic plate 7, a plurality of limiting holes 32 matching the second limiting protrusion 71 are opened on the air guide cover 3, the front end of the air guide cover 3 is inserted into the plug-in slot 45 so that the second limiting protrusion 71 is stuck in the limiting hole 32, and through the above structure, after the front end of the air guide cover 3 is inserted into the plug-in slot 45, the air guide cover 3 is connected to the plug-in slot 45. The function of 5 is to impose radial limitation between the mounting plate 4 and the air guide cover 3. After the second limiting protrusion 71 is inserted into the limiting hole 32, the axial limitation is imposed between the mounting plate 4 and the air guide cover 3 through the cooperation between the limiting hole 32 and the second limiting protrusion 71, thereby realizing the fixed connection between the mounting plate 4 and the air guide cover 3, and the connection operation between the mounting plate 4 and the air guide cover 3 is very convenient. The front end of the air guide cover 3 can be inserted into the plug-in groove 45. When the air guide cover 3 and the mounting plate 4 are removed from the mounting base 2 for cleaning, the second elastic plate 7 is moved to make the second limiting protrusion 71 withdraw from the limiting hole 32, and the mounting plate 4 can be removed from the air guide cover 3 to realize the separation of the two, thereby making it easier to clean the air guide cover 3 and the mounting plate 4.

[0028] Preferably, a plurality of spaced-apart air guide plates 33 are fixedly connected to the inner wall of the air guide cover 3, and an air guide channel 34 aligned with the cooling fan 5 is formed between two adjacent air guide plates 33. Through the above structure, the airflow drawn into the air guide cover 3 by each cooling fan 5 through the air inlet 41 flows rapidly along the air guide channel 34 corresponding to the cooling fan 5 on the surface of the body 1 to dissipate heat for the body 1, so that the airflow entering the air guide cover 3 when multiple cooling fans 5 are working will not interfere with each other to generate turbulence, thereby ensuring the rapid flow of the airflow in the air guide cover 3, and further ensuring the heat dissipation effect on the body 1.

[0029] Preferably, a support plate 46 is formed on the inner side surface of the mounting plate 4, which is against the body 1. Through the above structure, the support plate 46 supports the mounting plate 4 when the air guide cover 3 is connected to the mounting base 2 to cover the body 1, and then supports the cooling fan 5 and the air guide cover 3, so that the cooling fan 5 is more stably located in the front port of the air guide cover 3 to draw in the outside air to form a fast-flowing airflow, thereby ensuring the heat dissipation effect of the body 1.

[0030] Preferably, a shock-absorbing pad layer 47 is provided between the support plate 46 and the body 1. Through the above structure, the shock-absorbing pad layer 47 absorbs the vibration generated when the body 1 and the cooling fan 5 are working, thereby ensuring the stability of the connection between the mounting plate 4 and the air guide cover 3 and the air guide cover 3 and the mounting base 2.

[0031] Preferably, a plurality of heat dissipation fins 35 are fixedly connected to the outer wall of the air guide cover 3. Through the above structure, the heat dissipation fins 35 increase the contact area between the air guide cover 3 and the outside air, thereby dissipating the heat transferred to the air guide cover 3 into the air more quickly, thereby enhancing the overall heat dissipation efficiency of the air-cooling structure.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
