Motor shell water-cooling structure

Abstract

A motor shell water-cooling structure comprises a front end cover, a frame, and a rear end cover. The structure is characterized in that the wall of the frame is internally provided with a plurality of axial water guide holes; a groove is arranged between every two adjacent axial water guide holes at the rear end of the frame, a groove is arranged between every two adjacent axial water guide holes at the front end of the frame, and the rear grooves and the front grooves are staggered; there is one pair of front adjacent axial water guide holes which are not communicated; the end face of the front end cover is fixedly connected with the front end of the frame in a fitting way, and the end face of the rear end cover is fixedly connected with the rear end of the frame in a fitting way; the front end cover is provided with two holes which are respectively communicated with the pair of front adjacent axial water guide holes; and a sealing ring is arranged between the end face of the front end cover and the front end of the frame, and a sealing ring is arranged between the end face of the rear end cover and the rear end of the frame. Compared with the prior art, the motor shell water-cooling structure has the effects of simple structure, good sealing performance and reliable work and the advantages of firm fixation, wide range of application and higher efficiency of manufacture and production.

Description

technical field [0001] The invention relates to a motor casing. Background technique [0002] For the existing water-cooled structure motor housing, the manufacturing process is: after the machine base is extruded, a number of axial water channels are formed between the inner and outer walls, and the positions that need to be connected are cut and removed in the circumferential direction, so that the water channels are connected to each other. Then use the welding method to seal the two ends of the machine base to form a sealed circulating water channel, such as Figure 5 , Image 6 , Figure 7 As shown, when cooling, the cooling liquid is introduced from the water inlet 2 and exported from the water outlet 3 so as to take away the heat of the motor to achieve the effect of cooling the motor. [0003] The problem that this welding frame exists is: [0004] 1. Cracks are easy to occur at the position of the welding head, which is not easy to control and the process is diff...
