Abstract
The utility model relates to a cooling sleeve for an electric main shaft. The cooling sleeve comprises a sleeve body, wherein a cooling flow channel is formed in the sleeve body along the circumferential direction and comprises a water inlet gathering flow channel, a water outlet gathering flow channel and at least two cooling branches distributed along the circumferential direction; the water inlet gathering flow channel is communicated with water inlets of the cooling branches and provided with a main water inlet communicated with the exterior of the sleeve body; and the water outlet gathering flow channel is communicated with water outlets of the cooling branches and provided with a main water outlet communicated with the exterior of the sleeve body. A plurality of cooling branches are arranged on a shell along the circumferential direction, so that the circulation period of cooling water in the branches is short, and absorbed heat can be quickly brought away from an inner sleeve; furthermore, due to the short circulation period, the temperature difference of the cooling water and the inner sleeve, heat conduction is facilitated, and the cooling effect is good; and moreover, each branch share the main water inlet and the main water outlet, so that a cooling water circulation system is simplified, and the cost is saved.
