A kind of high-speed electric expreess locomotive
Technical field
The present invention relates to the motor cooled down by gaseous medium, especially a kind of high-speed electric expreess locomotive.
Background technology
It is known that high-speed electric expreess locomotive typically refers to the motor that rotating speed exceedes 10000r/min, it has small volume, transmission effect The characteristics of rate is high, noise is small, dynamic response is fast.Because the rotating speed of high-speed electric expreess locomotive is higher, compared with common electric machine, its radiating and Required in terms of vibration higher.Because there is the problems such as heating in winding, structural wear, each assembly temperature of motor is with the working time And raise, also limiting motor exports higher temperature while each part service life is shortened, and drags down electric efficiency.To understand The certainly heat dissipation problem of motor, at present, vast producer are mainly to install radiator fan additional by the non-shaft stretching end in motor, in motor Portion carries out forced cooling, but this mode has that radiating efficiency is low, can not meet the cooling requirements of high-speed electric expreess locomotive.In addition, The vibration of motor is often as the rotor of motor, caused by rotating shaft unbalance dynamic, and it not only can cause unnecessary energy to disappear Consumption, the parts such as the bearing of motor are also injured, shorten the service life of motor.At present, people are matched somebody with somebody by being riveted on rotor core The mode of weight adjusts rotor, the unbalance dynamic problem of rotating shaft, its complex operation and destruction rotor core, influences the magnetic of motor Flux density.
The content of the invention
In order to overcome existing high-speed electric expreess locomotive there is radiating efficiency it is low, plus counterweight speed governing complex operation and destroy rotor core Deficiency, the present invention provide it is a kind of it is reasonable in design, radiating efficiency is high, the simple high-speed electric expreess locomotive of balance adjustment.
The technical solution adopted for the present invention to solve the technical problems is:A kind of high-speed electric expreess locomotive, it include support, stator, Rotor, rotary shaft, two end cap and balancing frame, described rotor are fixed on the rotating shaft, and described stator respective rotor coordinates The inside of support, described end cap is individually enclosed on the both ends of support and warp beam forwards the axle stretch end of dynamic support rotating axle respectively With non-shaft stretching end, it is characterised in that:Air vent is had in described two end cap;It is non-close to rotary shaft in described support An air inlet is opened up in the side wall of axle stretch end, to fan housing should be sealed and installed with the support of air inlet, in the outer of the fan housing A blower fan is assembled in portion, and the output shaft of described blower fan stretches into fan housing and is being provided with impeller;Described balancing frame is assemblied in end Cover in the rotary shaft of inner side, some tapped through holes are provided with described balancing frame, select to be provided with described tapped through hole Mass.
Preferential, it is provided with dynamic seal between the axle stretch end and described end cap of described rotary shaft.
Preferential, described air vent is opened in side of the end cap away from air inlet.
Preferential, screen pack is installed on the air inlet of described support.
Preferential, described tapped through hole is distributed on balancing frame.
Preferential, the bearing between the axle stretch end and end cap of described rotary shaft is back-to-back duplex bearing.
The present invention is to open up an air inlet in side wall of the support close to rotary shaft non-shaft stretching end, in the machine of corresponding air inlet Fan housing is sealed and installed with seat, has blower fan in the external mounting of fan housing, the output shaft of blower fan stretches into fan housing and is provided with impeller, Blower fan drives wheel rotation, and air is sent into motor internal by impeller through the air inlet on support, and air completes heat in motor internal Amount is discharged after exchanging by the air vent being provided with two end cap, and its is reasonable in design;Fan housing, blower fan and impeller are independently arranged at support On outer wall, forced heat radiation is carried out to motor internal, its radiating efficiency is high, compared with installing fan additional in the non-shaft stretching end of motor, its The Double shaft-extension structure of motor is not influenceed, and does not increase the length of motor rotation axis, and it occupies little space, be compact-sized;Holding Cover in the rotary shaft of inner side and be equipped with balancing frame, some tapped through holes are provided with balancing frame, select to be provided with tapped through hole Dynamically balanced adjustment can be achieved in counterweight screws, and compared with riveting counterweight on rotor core, its weighting operation is simple, does not destroy Rotor core.
