Description

Technical Field

[0001] The utility model belongs to the technical field of speed reducers, and in particular relates to a speed reducer with an auxiliary heat dissipation structure. Background Art

[0002] A reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a prime mover to reduce the speed of a working machine. According to its structure, it can be divided into gear reducers, planetary gear reducers, and worm reducers, etc. It is widely used in various modern machinery.

[0003] The existing document with announcement number CN218408443U discloses a reducer with an efficient heat dissipation structure, including a base and an upper cover. The base supports an input shaft, an output shaft, and a conversion shaft. The input shaft and the output shaft are connected by gear meshing. The output shaft and the conversion shaft are connected by gear meshing. The conversion shaft is located between the input shaft and the output shaft. A heat dissipation unit is detachably provided on the input shaft. The heat dissipation unit is provided with a main blade. The rotating surface of the main blade is perpendicular to the axis of the input shaft. An air duct is provided on the inner side of the upper cover. The air duct is used to transfer the cold air generated by the rotation of the main blade to a side away from the input shaft.

[0004] However, it still has the following disadvantages in actual use:

[0005] In the above-mentioned reducer, the input shaft and the output shaft are meshed with each other through the gear and the conversion shaft, so that the speed between the input shaft and the output shaft is changed by the conversion shaft. However, during use, since the directions of the input shaft and the output shaft are consistent, it can only transmit and connect two devices in the same direction, which has poor practicality.

[0006] The reducer mentioned above has a detachable heat dissipation unit on its input shaft, the heat dissipation unit is provided with a main blade, and an air duct is also provided on one side of the main blade. The main blade and the air duct are used to cool the reduction structure in the base and the upper cover. However, during use, it is cooled by the outside air, and the cooling effect is poor. At the same time, the outside air contains impurities such as dust, which will affect the transmission between the input shaft, the conversion shaft and the output shaft.

[0007] To this end, we provide a reducer with an auxiliary heat dissipation structure to solve the above problems. Utility Model Content
