Abstract
The utility model provides a totally-enclosed self-ventilation type asynchronous traction motor, which comprises a traction motor stator, a traction motor driving end and a traction motor non-driving end, wherein the traction motor driving end comprises a driving end stator pressing ring and a driving end cover and is connected with the traction motor stator through a bolt; and the traction motor non-driving end comprises a non-driving end stator pressing ring and a non-driving end cover and is fixed with the traction motor stator through a bolt. An outer fan structure is adopted by the traction motor non-driving end and an inner fan structure is adopted by the traction motor driving end, so circulation of an internal wind path is increased, the heat produced by a rotor is exchanged with the inner surface of the traction motor stator in an air gap, and temperature rise of a bearing is effectively reduced. A discontinuous outer seam allowance structure is adopted by a traction motor stator core, and the positions where three phase outgoing line comes out of the driving end cover and the driving end stator pressing ring are designed into groove structures, so the operation space of the three phase outgoing line at the inner part of the motor can be increased.

Background technology
In the mobile devices such as railway locomotive, motor-car, electric automobile, traction electric machine works under the adverse circumstances such as high temperature, sleet, dust, vibration, and spatial volume is limited, and therefore, totally-enclosed is a kind of effective means that improves the motor reliability.But adopt totally-enclosed after, the heat that motor internal distributes is difficult to be taken away by cooling air, therefore, it is very fast that the rotor temperature rises, the heat of motor internal is passed to bearing rapidly by rotating shaft, end cap position, makes the bearing temperature fast rise.Because the permission temperature rise of motor stator and rotor is generally 180K even 200K, and the permission temperature rise of motor bearings 55K only, therefore, the heat radiation of the bearing of totally-enclosed traction electric machine becomes one of outstanding problem that influences its useful life and reliability.
At present, adopt the mode that reduces motor electromagnetic load and heating factor usually, reduce the temperature rise of motor stator and rotor, with the overheated bearing burnt that causes of prevention motor bearings.But so,, increased motor volume and weight, reduced the cost performance of motor though guaranteed the bearing reliability.Therefore need further to be improved.
Summary of the invention
The purpose of this utility model in order to overcome the deficiency that existing totally-enclosed machine exists, proposes a kind of totally-enclosed self-ventilation type asynchronous traction motor exactly, this structure can well reduce bearing temperature rise, increase the motor internal space, alleviate the weight of motor, reduce the volume of motor.
In order to reach above-mentioned specification requirement, the totally-enclosed self-ventilation type asynchronous traction motor contour structures that the utility model adopts is: a kind of totally-enclosed self-ventilation type asynchronous traction motor, comprise the traction electric machine stator, traction electric machine driving end and traction electric machine non-transmision end, wherein the traction electric machine driving end comprises driving end stator pressing ring and driving end end cap, the traction electric machine driving end links together by bolt and traction electric machine stator, the traction electric machine non-transmision end comprises non-transmision end stator pressing ring and non-transmision end end cap, traction electric machine non-transmision end and traction electric machine stator pass through bolt, the traction electric machine non-transmision end adopts the structure of external fan, the traction electric machine driving end adopts the structure of internal fan, increased the circulation of inner wind path, the heat that rotor is produced exchanges with the traction electric machine stator inner surface in air gap, effectively reduces bearing temperature rise.In order to increase the inner space of traction electric machine, alleviate the volume of traction electric machine, discrete male half coupling structure is adopted in the traction electric machine stator core.The Position Design that driving end end cap and driving end stator pressing ring are gone out the three-phase lead-out wire becomes the structure of groove, can increase the operating space of motor internal three-phase lead-out wire.
The utility model is a kind of totally-enclosed self-ventilation type asynchronous traction motor contour structures.This kind motor contour structures mainly contains following advantage: the one, effectively reduce bearing temperature rise; The 2nd, increase the motor internal space; The 3rd, alleviate the weight of motor.
