[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine.

[0003] Reducers are widely used and applied in production and life. With the continuous expansion of application fields, the types and functions of reducers are becoming more and more diverse and complete. Various types of reducers are also commonly used in the field of industrial robots, one of which is harmonic reducer. Some traditional harmonic reducers usually do not have good heat dissipation performance. If the heat dissipation of the harmonic reducer is not good, the aging of the harmonic reducer will be accelerated. Therefore, a structure is set to solve the problem of poor heat dissipation performance of some harmonic reducers.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] The heat dissipation reducer, such as Figure 1 and Figure 2 As shown, it includes a motor 1 and a reduction body 2 that is transmission-connected to the motor 1, the reduction body 2 includes a casing 3, and a heat-conducting heat dissipation part that is in contact with the casing 3 is fixedly connected to the outer wall of the casing 3 by welding. The heat-conducting heat dissipation part and the casing 3 are in contact with each other, so that the heat-conducting heat dissipation part can absorb the heat from the casing, and then the heat exchange between the heat-conducting heat dissipation part and the air can realize the stable auxiliary heat dissipation function of the heat-conducting heat dissipation part, further enhance the heat dissipation stability of the overall structure, realize stable protection of the reduction body 2 during operation, and ensure better stability and service life of the reduction body 2.

[0019] like Figure 1 and Figure 2As shown, the heat-conducting and heat-dissipating part includes circumferentially respectively and alternately arranged fitted heat dissipating strips 4 and suspended heat dissipating strips 5, the fitted heat dissipating strips 4 and the outer side wall of the casing 3 are fitted with each other, and by virtue of the mutual fitting between the fitted heat dissipating strips 4 and the casing 3, the fitted heat dissipating strips 4 can fully exchange heat with the casing 3 through the contact with the casing 3, so that the fitted heat dissipating strips 4 can stably absorb the heat on the casing 3, thereby ensuring that the heat dissipation performance of the overall structure is more stable, and auxiliary heat dissipation grooves 6 are arranged between the suspended heat dissipating strips 5 and the outer side wall of the casing, and under the action of the auxiliary heat dissipation grooves 6, it is ensured that the suspended heat dissipating strips 5 can better contact with the air and exchange heat with the air, ensuring that the suspended heat dissipating strips 5 can better exchange heat with the air.

[0020] like Figure 1 and Figure 2 As shown, the cross-sectional shapes along the width direction of the fitted heat dissipation strip 4 and the suspended heat dissipation strip 5 are both set to be arc-shaped with the concave surface facing the outer wall of the casing 3. On the one hand, this setting ensures that the fitted heat dissipation strip 4 can be more fully fitted and contacted with the casing 3, so that the fitted heat dissipation strip 4 can better absorb heat from the casing 3 and perform auxiliary heat dissipation. On the other hand, with the help of the concave surface of the suspended heat dissipation strip 5, the auxiliary heat dissipation slot 6 can be more fully opened, and at the same time, the contact area between the suspended heat dissipation strip 5 and the air and the heat exchange area can be increased, so that the auxiliary heat dissipation function of the suspended heat dissipation strip 5 is more complete and stable.

[0021] like Figure 1 and Figure 2 As shown, the suspended heat sink 5 is mutually attached to the two adjacent bonded heat sinks 4 and fixed to each other by welding. The heat absorption of the machine housing 3, the bonded heat sink 4 and the suspended heat sink 5 increases gradually. The suspended heat sink 5 is made of silver material, the bonded heat sink 4 is made of copper material, and the machine housing 3 is made of cast iron. This arrangement ensures that the heat absorption of the machine housing 3, the bonded heat sink 4 and the suspended heat sink 5 increases gradually. The heat absorbed by the machine housing 3 will be absorbed by the bonded heat sink 4, and the heat absorbed by the bonded heat sink 4 will be transferred to the suspended heat sink 5, so that the heat generated by the reducer body 2 can be stably absorbed by the heat conduction and heat dissipation part and be transferred to the air. Heat exchange makes the heat dissipation performance and use stability of the whole structure better. The heat dissipation strip 4 on the side away from the machine casing 3 is fixedly connected with a plurality of heat sinks 7 distributed in an array along its length direction by welding. The heat sink 7 is made of silver material. With the help of the heat sink 7, the contact area between the whole heat dissipation strip 4 and the air can be further increased, so that the area of heat exchange between the whole structure and the air is larger, and the heat dissipation performance and use stability of the whole structure are further enhanced. The heat sink 7 is set to be a silver material, so that the heat sink 7 can better absorb the heat on the heat dissipation strip 4 and exchange heat with the air.

All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
