Abstract
The utility model provides a low temperature high ductility shock resistance high speed motor train unit pulling motor driving motion end cover device which includes an end cover body (1) with an inner hole in centre, one end of the end cover body (1) is equipped with a connecting table (2) for connecting with a motor stand, the connecting table (2) is opened with some breathing places (3) with pylome shape; an exterior side wall surrounding the end cover body (1) is equipped with some muscle plates (4). The device is made of the high ductility ball iron material satisfying low temperature impact test requirement which has high intension, shock resistance and better heat dispersion ability, the inner hole is not easy deformed after processing which can satisfy performance requirement of the high speed motor train unit accessory.
Description
(1), technical field
The utility model relates to a kind of drive of motor end end cap device, specifically a kind of low-temperature high-toughness shock resistance EMU traction electric machine driving end end cap device.
(2), background technology
For adapting to the high-speed overload requirement, the traction electric machine driving end end cap of EMU need be selected the shock proof ductile iron material of low-temperature high-toughness for use, and the material of existing traction electric machine driving end end cap can not satisfy the shock proof requirement of low-temperature high-toughness.On the other hand, existing traction electric machine driving end end cover structure is reasonable inadequately, ubiquity end cover body intensity can not be satisfactory, endoporus is easily deformable, and end cap and the unfavorable shortcoming of electric machine stand junction radiating effect are not only brought difficulty to assembling, and also can occur vibration and noise when the train high-speed cruising, influence the useful life of electric machine stand, even burn-out motor.
(3), utility model content
Technical problem to be solved in the utility model is, a kind of low-temperature high-toughness shock resistance EMU traction electric machine driving end end cap device is provided, and it is shock-resistant to resist low temperature, high tenacity, perfect heat-dissipating, not yielding after the endoporus processing, to overcome the defective of above-mentioned existing procucts.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme.
A kind of low-temperature high-toughness shock resistance EMU traction electric machine driving end end cap device, the end cover body that comprises center band endoporus, it is characterized in that: an end of end cover body is provided with and is used for the connection platform that is connected with electric machine stand, offers the ventilating opening of several through-hole forms on this connection platform; On the lateral wall of end cover body, some gussets are set.
Described gusset is ten.
The utlity model has following characteristics.
(1), this device adopts the high-toughness ductile iron material of low-temperature impact resistance test requirements document to make, under the situation that satisfies driving end end cap requirement of strength, not only can economical with materials, alleviate own wt, and alleviated the weight of whole motor train unit greatly.
(2), the end cover body lateral wall is provided with the reinforcement gusset, under the prerequisite that does not increase wall thickness, makes bulk strength improve, and is convenient to the processing of endoporus, the endoporus of processing is not yielding, satisfies the requirement of bullet train accessory.
(3), on the connection platform that is connected with electric machine stand, offer ventilating opening, can strengthen the area of dissipation of driving end end cap, reach the temperature around the quick reduction support, prolong the useful life of motor.
(4), description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a front elevational schematic of the present utility model.
Fig. 3 is a schematic side view of the present utility model.
(5), embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, 2, present embodiment comprises end cover body 1, offers the ventilating opening 3 of a plurality of through-hole forms on the connection platform 2 that an end of end cover body 1 is used for being connected with electric machine stand, and ventilating opening 3 is evenly distributed on connection platform 2.On the lateral wall of end cover body 1, ten place's gussets 4 are set.
As shown in Figure 3, gusset 4 can be connected with the two ends of end cover body 1, also can be connected with an end of end cover body 1.
This device adopts the impact-resistant high-toughness ductile iron material of the anti-low temperature of QT400-18L to make.
Claims (2)
1, a kind of low-temperature high-toughness shock resistance EMU traction electric machine driving end end cap device, the end cover body (1) that comprises center band endoporus, it is characterized in that: an end of end cover body (1) is provided with and is used for the connection platform (2) that is connected with electric machine stand, offers the ventilating opening (3) of several through-hole forms on this connection platform (2); On the lateral wall of end cover body (1), some gussets (4) are set.
2, low-temperature high-toughness shock resistance EMU traction electric machine driving end end cap device as claimed in claim 1, it is characterized in that: described gusset (4) is ten.
