Description
Technical field
The present invention relates to the wheels of rail vehicle truck to composition, more particularly, to a kind of torque for exporting traction electric machine
Or power is directly passed to the wheel of wheel pair or framework to composition.
Background technique
Currently, straight drive wheel both domestic and external is to composition, motor both ends are connect by plain bearing and transition axle sleeve with axle, only
Magnetic field is adjusted by adjusting the exciting current of stator, to realize the speed regulation to motor, there is detection motor rotor position not
Easily shake, the disadvantages of output power is unstable when enough accurate, electric motor starting.Meanwhile the bearing one end at motor both ends is positioning
End, the other end is floating end, in order to the transverse shifting of stator and rotor is discharged, to reduce between rotor and stator
Stress.But positioning end still will limit the transverse shifting of rotor and stator, stress still has, and energy consumption is larger, service life
Allowance is low.
Summary of the invention
Background technique there are aiming at the problem that, mesh of the invention is to provide the wheel pair that a kind of traction electric machine directly drives axle
Component devices, the lateral displacement of quick release stator and rotor eliminate stress, more accurately control motor, reduce energy consumption, are promoted
Service life safety allowance.
To achieve the above object, the present invention provides a kind of traction electric machine and directly drives the wheel of axle to component devices, special
Sign is: rotor is directly installed on axle, and conical bearing is installed at axle both ends, and assembly back axle both ends are to float
It holds, rotary transformer is installed on the bearing seal of axle one end, the rotor and axle of rotary transformer rotate synchronously, rotation
The stator of transformer and motor stator are relatively fixed, and rotary transformer connects the traction invertor on vehicle by data cable, from
And motor is more accurately controlled, keep the revolution of motor and output torque more stable.
The stator of the rotary transformer is assemblied in bearing seal and covers, and the rotor of rotary transformer passes through end ring
Locating slot location and installation is on end ring.
The rotor of the rotary transformer is equipped with convex key, is provided with keyway on outer retaining ring, the rotor of rotary transformer
The keyway of convex key and outer retaining ring passes through clearance fit.
Adjusting pad is installed between the motor stator and end cap, for adjusting the clearance of conical bearing, to guarantee to justify
The service life of cone bearing.
Compared to background technique, the good effect that the present invention generates is as follows:
(1) rotor of motor is directly assemblied on axle, omits transition axle sleeve, mitigates weight, both ends are assembled conical bearing, made
Both ends are all floating end, and energy quick release rotor and stator lateral displacement are eliminated the stress between rotor and stator, be precisely controlled
Motor reduces energy consumption to greatest extent, promotes service life safety allowance;
(2) rotary transformer is housed, rotary transformer connects traction invertor, provides axle movement for traction invertor on axle
Waveform more accurately controls motor to more accurately find the position of rotor, makes the revolution and output torque of motor
It is more stable.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention;
Fig. 2 is the enlarged drawing of I of the present invention.
Fig. 3 is the enlarged drawing of II of the present invention.
Specific embodiment
Referring to Fig.1, Fig. 2, Fig. 3, the specific embodiment of the invention are: 1 rigidity of rotor is assemblied on axle 2, with
Guarantee that the torque of motor output can be directly passed to axle.With the conical bearing 5 of 4 clamping motor of inner shield ring 3 and outer retaining ring, to protect
The conical bearing for demonstrate,proving motor can horizontally positioning motor stator 7 and carrying radially.Motor stator 7 is connected to end cap 6,
And conical bearing 5 is transferred load to by end cap 6, the clearance of conical bearing 5 can be adjusted, by adjusting pad 8 to guarantee to justify
The service life of cone bearing.It seals front cover 9 and rear sealing cover 10 and end cap 6 and provides the sealing space of operation for conical bearing.It is logical
Cross 11 sealed electric-motor chamber of O-ring.The running space of conical bearing is preferably sealed with diaphragm seal 12.The stator of rotary transformer
13-1 is assemblied on bearing seal cover 9, and the rotor 13-2 of rotary transformer passes through on convex key slot assembly thereon and outer retaining ring 4, outside
Retaining ring 4 is equipped with positioning spline, the convex key of the rotor of rotary transformer and outer retaining ring positioning spline and is cooperated by small―gap suture, thus
It realizes synchronous with axle turn, stop, by data cable 13-3, by waveform transfer to traction invertor, and then assist more accurately
Control revolution, the torque of motor.Traction invertor is assemblied in car body or other positions.Wheel 14 and 2 rigidity of axle are assembled, with
Guarantee that wheel 14 is rotated synchronously with axle 2.
