Abstract
The utility model discloses a motor shell provided with a cooling water jacket, which comprises a motor shell. An inner sleeve is sheathed at the inner wall of the motor shell; a water cavity is arranged between the outer wall of the inner sleeve and the inner wall of the shell; a guiding strip-shaped rib is arranged on the inner wall of the shell or the outer wall of the inner sleeve; two ends of the inner sleeve are sealed relative to the inner wall of the shell; and a water inlet opening and a water outlet opening are arranged in the motor shell. For the motor shell, the inner sleeve is sheathed at the inner wall of the shell, the water cavity is arranged between the outer wall of the inner sleeve and the inner wall of the shell, and the guiding strip-shaped rib is arranged on the inner wall of the shell or the outer wall of the inner sleeve; the motor shell is simple in structure; and due to the arrangement of the guiding strip-shaped rib, the flow direction and the flow speed of cooling liquid can be optimized, and the cooling effect and the processing manufacturability of the water jacket can be improved.
Description
Technical field
The utility model belongs to auto parts and components, is specifically related to a kind of HEV gearbox motor cooling device.
Background technology
The ambient temperature of machine operation directly influences operating efficiency, life-span of motor etc., if the motor inhomogeneous cooling is spared and is worked under the continuous high temperature environment, then electric efficiency, life-span can decrease, simultaneously rotor, stator and cylinder sleeve may expanded by heating and cause distortion, reduced bulk strength, thereby the gap between cylinder sleeve and the stator increases, and vibration noise also may produce.In order to make automobile-used motor be in good working environment, the motor water cooling technology is fast-developing at present.The jacket structure for water of existing water-cooled machine is comparatively complicated, has increased manufacturing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of electric machine casing of band cooling jacket simple in structure, to overcome the defective of above-mentioned technology.
The technical solution of the utility model is: the electric machine casing of band cooling jacket, and it comprises electric machine casing, the electric machine casing inner wall sleeve is provided with interior cover, is provided with water cavity between outer wall of inside race and the inner walls; On the inner walls or outer wall of inside race be provided with water conservancy diversion bar shaped muscle, seal between the two ends of interior cover and the inner walls, offer inlet opening and apopore on the electric machine casing.
Staggered respectively vertically two ends or the outer wall of inside race two ends that are located at inner walls of described water conservancy diversion bar shaped muscle; The length of water conservancy diversion bar shaped muscle is less than the axial length of water cavity, greater than half of the axial length of water cavity.
The two ends of described inner walls are provided with first sealed step and second sealed step, and water cavity is located between first sealed step and second sealed step; First sealed step is connected spacing sealing with the two ends of interior cover respectively with second sealed step.
The utility model is provided with interior cover at the electric machine casing inner wall sleeve, is provided with water cavity between outer wall of inside race and the inner walls; On the inner walls or outer wall of inside race be provided with water conservancy diversion bar shaped muscle, it is simple in structure, the setting of water conservancy diversion bar shaped muscle is optimized cooling fluid and is flowed to and flow velocity, improves the processing technology of cooling effect and water jacket.
