Abstract
The utility model relates to a pulling motor, especially a simple and convenient pulling motor water-cooling mechanism, which is characterized in that an electric motor case is divided into an inner cylinder and an outer cylinder, the outer wall of the inner cylinder is provided with a flow passage, a heating sleeve of the outer cylinder is interference fit with the inner cylinder, a cooling water channel is formed between the walls of the outer cylinder and the inner cylinder, and the cooling water channel is communicated with a water inlet and a water outlet. The utility model has simple structure, combines the cooling water and the machine body as a whole, a spiral cooling water channel is formed between the outer cylinder and the inner cylinder, thereby no needing to add other cooling mechanism, uniformly distributing the cooling medium and directly exchanging the heat, and improving the cooling effect. The outer cylinder is provided with a water inlet and a water outlet of the cooling channel, and the water inlet and the water outlet are respectively arranged at the start end and the tail end of the screw thread, the end of the combination of the inner cylinder and the outer cylinder adopts welding sealing, and the watertightness is detected by a hydraulic test. The utility model greatly simplifies the manufacturing technology, reduces the processing cost, and improves the electric motor performance.
Description
One, technical field:
The utility model relates to traction electric machine, particularly its water-cooled mechanism.
Two, background technology:
Traction electric machine is in the course of the work because heat makes motor self heat up, the too high life-span and the operating efficiency that will influence motor of temperature, therefore be equipped with cooling body on the traction electric machine, cooling body is a water-cooled mechanism at present, adopts usually cavity is set in the motor case, heeling-in copper pipe in the cavity, with the logical cooling water of copper pipe, its preparation process complexity, cost height, because heat exchange is hindered by structure between coolant and the body, cooling effect is poor.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of easy traction electric machine water-cooled mechanism is provided, and simple in structure, cooling effect is good.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of simple traction electric machine water-cooled mechanism, motor case is divided into inner core and urceolus, the inner tank theca face offers runner, urceolus heat hot jacket and inner core interference fit, form cooling water channel between the inside and outside barrel, cooling water channel is communicated with water inlet and delivery port.
Described urceolus is offered cooling water channel water inlet and delivery port, and water inlet and delivery port lay respectively at the top of runner with terminal.
The runner that described inner tank theca face is offered is the screw thread runner.
Described screw thread runner is the rectangular thread runner.
The utility model is simple in structure, cooling water and body combination are one, spiral cooling water channel between the inner/outer tube, need not to add cooling body, coolant distribution is even and heat exchange is direct, has improved cooling effect again, urceolus is provided with the water inlet and the delivery port of cooling water channel, water inlet and delivery port lay respectively at the top of screw thread with terminal, and welded seal is adopted in the end of inner/outer tube combination, detects the watertightness of welding by the hydraulic test.The utility model has been simplified manufacturing process greatly, cuts down finished cost, and improves motor performance.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Five, embodiment:
A kind of simple traction electric machine water-cooled mechanism as shown in Figure 1, motor case is divided into inner core 4 and urceolus 2, inner core 4 outside wall surface offer rectangular thread, urceolus 2 heat hot jacket and inner core interference fit, form screw thread cooling water channel 3 between the inside and outside barrel, urceolus is offered cooling water channel water inlet 1 and delivery port 5, and water inlet and delivery port lay respectively at the top of screw thread with terminal, and cooling water channel is communicated with water inlet and delivery port.
