Abstract
The utility model relates to a traction motor casing for high-speed electric multiple units. The traction motor casing (1) takes the form of an integral cast unit and has a frame structure as follows: a heat-dissipating opening (2) is formed at the upper end of the traction motor casing (1) and communicated with the inner cavity of the traction motor casing (1); the traction motor casing is integrally cast of a material with resistance against low-temperature impact (50 DEG C below zero), has good installation stability and remarkably-high strength, and can meet the requirement for high-speed impact at 350 mph; the traction motor casing is a thin-walled frame structure with light weight and less space occupancy; and a ventilation opening is arranged at the upper end of the traction motor casing to improve the heat dissipation effect.
Description
Technical field
The utility model relates to a kind of isolated plant as electric machine casing, particularly a kind of electric machine casing that is used for the EMU traction electric machine.
Background technology
Along with the develop rapidly of Chinese national economy, the contradiction between railway capacity and the freight volume becomes increasingly conspicuous.Further excavating the railway capacity is the major issue that current Chinese Railway needs to be resolved hurrily.And raise speed, heavy duty is further to enlarge the most effectively means of railway capacity.Motor train unit is the most effectively one of means of transportation of railway high speed passenger traffic.
The general split processing of prior motor housing welds together each assembly then, and less stable is installed, and bulk strength is relatively poor.On the other hand, existing electric machine casing generally has thicker seat wall, causes that overall volume is big, self body weight is big, takies more installing space.The third aspect, the electric machine casing heat dispersion can not be satisfactory.Key a bit is that the prior motor housing only adapts to the motor operation trailer system under the normal temperature, does not possess the characteristic of low-temperature resistant and shock resistant.Therefore, the prior motor housing can not adapt to the instructions for use of high speed motor car traction electric machine.
The utility model content
Technical problem to be solved in the utility model is, overcome the defective of above-mentioned existing procucts, a kind of EMU traction electric machine housing is provided, guarantee its low-temperature impact toughness, improve its job stability, reduce its volume, weight, and improve its heat dispersion, reach shock proof requirement under its low temperature.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme.
A kind of EMU traction electric machine housing is characterized in that: the traction electric machine housing is the monoblock cast form, adopts frame structure; Traction electric machine housing upper end has the thermovent that communicates with traction electric machine housing inner chamber.
The material of traction electric machine housing adopts-50 ℃ of low-temperature impact resistance materials.
The sidewall thickness of traction electric machine housing is the 8--10 millimeter.
Good effect of the present utility model is: (1) electric machine casing monoblock cast forms, and good stability is installed, and intensity significantly improves.(2) adopt-50 ℃ of low-temperature impact resistance made, shock resistance is good, and every performance is up to standard, can satisfy the low-temperature impact requirement that runs up of 350 kilometers of speed per hours.(3) adopt thin walled framed structure, case weight is light, and it is little to take up room.(4) upper end is provided with the ventilation and heat mouth, and radiating effect is better.

Fig. 3 is the A-A cutaway view of Fig. 1.
Embodiment
As shown in Figure 1, 2, 3, this traction electric machine housing 1 adopts-50 ℃ of low-temperature impact resistance material monolithic castings to form, and has thin walled framed structure.
As shown in Figure 2, traction electric machine housing 1 upper end has the thermovent 2 that communicates with the housing inner chamber.
As shown in Figure 3, sidewall 3 thickness of traction electric machine housing 1 are 9 millimeters.
Ballistic work 〉=12J when described-50 ℃ of low-temperature impact resistance materials, performance requirement-50 ℃, room temperature tensile strength 〉=400Mpa, elongation 〉=18%.
Claims (2)
1, a kind of EMU traction electric machine housing is characterized in that: traction electric machine housing (1) is the monoblock cast form, adopts frame structure; Traction electric machine housing (1) upper end has the thermovent (2) that communicates with traction electric machine housing (1) inner chamber.
2, EMU traction electric machine housing according to claim 1 is characterized in that: sidewall (3) thickness of traction electric machine housing (1) is the 8--10 millimeter.
