Welding-free water-cooled motor shell and motor thereof

Abstract

The invention discloses a welding-free water-cooled motor shell, which comprises a shell, a water inlet and a water outlet arranged on the shell, a front end cover arranged at the front end of the shell and a rear end cover arranged at the rear end of the shell, and is characterized in that the shell is fixedly connected with the front end cover and the rear end cover, and is provided with a plurality of axial water channels which are circumferentially distributed and penetrate through the shell; and the front end cover and the rear end cover are provided with a plurality of arc-shaped water channels used for being connected with the axial water channels, the axial water channels are connected in series through the arc-shaped water channels, and water inlets and water outlets are formed in the water channels. The axial water channels of the casing and the arc-shaped water channels of the front end cover and the rear end cover jointly form the U-shaped water channel, and the two ends of the water channel do not need to be blocked by a welding process, so that the influence on the product quality and the yield caused by welding defects or welding slag falling into the water channel is avoided, the product yield is improved, and the product cost is reduced.

Description

technical field [0001] The invention relates to the technical field of motor housing structures, in particular to a welding-free water-cooled motor housing and a motor thereof. Background technique [0002] At present, the cooling water channels of water-cooled motors are all internal water channels in the casing, mainly in two forms: spiral water channels and U-shaped water channels. Among them, the spiral water channel needs to be cast, while the U-shaped water channel can be formed by extrusion mold, and the forming process is simpler. At the same time, because the U-shaped waterway casing is an extruded material, the length of the casing can be adjusted, which is more suitable for motors of the same diameter series and different lengths, so that the casing is more versatile. [0003] The casing of the current U-shaped water channel basically adopts a welding process to seal the two ends of the profile. In the welding process, it is easy to cause welding defects, result...

AI Technical Summary

Problems solved by technology

In the welding process, welding defects are prone to occur, which affects product quality and yield

At the same time, in terms of technology, rough machining is required first, and then welding is required. After welding, finishing machining is required. The process is too complicated and the cost is high.
