Ask, and in particular to a kind of evanohm disc type vee-pulley motor.
Background technology
EMU has special rigors to the motor performance of trailer system, e.g., high pulling torque, low noise, bending resistance
Square and radiating efficiently etc., for this purpose, European and American developed countries mostly adopt disc type electric machine.Traditional radial magnetic field magneto by
Spatially there is the relation of vying each other in electric load and magnetic loading, therefore, power of motor density and output torque density are little, one
As make the torque motor of big torque, but material cost is high.Existing disc-type permanent magnet motor, its air gap main field are axial direction,
Also known as axial magnetic field permanent magnet motor, which using radial direction and axial space, is able to power of motor density and torque density well
Improve.Advantage is：Axial dimension is short, compact conformation, and torque inertia is low.From from topological structure, its rotor point surface is bonded
And built-in embedded, both of which easily makes the axial air-gap magnetic field saturation of inner radius, and the effective rate of utilization of permanent magnet is low, causes forever
The waste of magnet.Additionally, motor is in addition to being exported with associated mode, machine shaft is solely subjected to pure torsion.It is companion when more
Export with the torsional forces mode for having radial direction moment of flexure, such as：Vee-pulley etc..In the case of equal-wattage and rotating speed, bending is carried
The machine shaft diameter of synthesis is that more than the twice of the machine shaft diameter for carrying pure torsion just can ensure that enough safety systems
Number.Therefore, in order to allow machine shaft bear bending moment force, it has to increase exponentially machine shaft diameter, ultimately result in one
Serial drawback：Motor bearings linear velocity is also increased exponentially, and itself in-fighting is increased exponentially, and in-fighting causes caloric value to increase exponentially.

The rotational clearance 48 of rice；
（Two）, needle roller outer ring 69 is installed, no inner-ring bearing 60 selects RNA type separate type no inner-ring bearings.First by V-belt
92 gap of wheel adjusting ring coordinates among the belt wheel stepped hole 96 being put on vee-pulley 90 and crosses vee-pulley escape 93 pastes
On vee-pulley bottom hole face 95；Again by the needle roller outer ring 69 slight interference fit press-in vee-pulley 90 on no inner-ring bearing 60
On belt wheel stepped hole 96 among, finally V-belt wheel bore snap ring 91 is put in vee-pulley draw-in groove 98 with specific purpose tool,
So that 69 both sides of needle roller outer ring are respectively close to V-belt wheel bore snap ring 91 and vee-pulley adjusting ring 92；
（Three）, connection between vee-pulley 90 and machine shaft 40：By the needle roller outer ring being fixed on vee-pulley 90
69 are inserted in together with cylinder needle roller 68 and are fixed on outer bearing and hold round 89 last points, slowly rotate vee-pulley 90 so that
V-belt splined hole 94 on vee-pulley 90 is aligned with the shaft end spline 49 on machine shaft 40 and is engaged, and continues to push against triangle
Belt wheel 90 so that 68 entirety of cylinder needle roller on needle roller outer ring 69 holds round 89 with outer bearing and is engaged completely；
First take step backing-up screw 74 pass through after 70 centre bore of axially position back-up ring with machine shaft 40 on shaft end spiral shell
Hole 47 is engaged so that outside on step backing-up screw 74 the two flat side bumper of axially position back-up ring 70 shoulder cap 73 and shaft end spline 49
There is one millimeter of axially free amount between end face；
With vee-pulley 90 after the positioning retainer ring through hole 76 for being passed through on axially position back-up ring 70 with five back-up ring screws 77 again
On vee-pulley end face screw 97 be engaged, axially position back-up ring 70 is also fastened on 90 outer face of vee-pulley；
Determining on the through hole and axially position back-up ring 70 for finally being passed through on locking catch 71 successively with a back-up ring screw 77
Also it is engaged with the vee-pulley end face screw 97 on vee-pulley 90 after position back-up ring through hole 76 so that the gear on locking catch 71
On any one flat side on two flat side bumper shoulder cap 73 of the alignment of piece corner edges 72, play and loosen effect.
Install.
5th, run：
When the motor is energized, the moment of torsion that electromagnetic force is produced passes through the shaft end spline 49 on machine shaft 40, through vee-pulley
V-belt splined hole 94 on 90 passes to the V-type trough of belt 99 on vee-pulley 90, realizes torque output.
Table 1 is the fore bearing section 45 that present invention employs the machine shaft 40 fixed by component component fore bearing 25 after 80s
Radius run-out degree micron and the front axle of the machine shaft 40 that is not fixed using the fore bearing 2 of the constant power motor of component component 80
The experimental data for holding 45 radius run-out degree micron of section compares.
The data of the radius run-out degree micron at 1 fore bearing section of table, 45 position compare
Contrasting data from table 1 can draw：It is after 80s that 25 outer end of fore bearing employs component component, suffered by fore bearing 25
Mitigate abrasion to load to reduce, the radius run-out degree at 45 position of fore bearing section of the machine shaft 40 for causing fore bearing 25 to be fixed
Micron is more stable.
Component component 80 is set on the drive end bearing bracket 20 of motor, has shared all of moment of flexure load so that machine shaft 40
The machine shaft diameter being solely subjected under pure torsion, equal-wattage can reduce half, finally realize that motor integrally has breakthrough
Compact.Due to meeting on the premise of rated power, the diameter for seeking machine shaft 40 can be accomplished that the limit is little in design,
Pure torsion is solely subjected to, simultaneously as 80 global shape of component component belongs to hollow short tube, therefore structural rigidity is superpower, can bear
Bigger radial load.Both combine, present invention achieves can be made compact motor overall dimensions, can bear bigger footpath again
Xiang Li, operation are relatively reliable, so as to extend the service life of motor.
Table 2 is that outer bearing in the present invention holds round 89 surfaces and employs the evanohm that a layer thickness is 0.2 to 0.3 millimeter
Hard wear-resistant layer and outer bearing hold round 89 surfaces and do not adopt a layer thickness for 0.2 to 0.3 millimeter of evanohm hard wear-resistant layer
Corrosion resistant wear test data compare.
The outer bearing of 2 component component 80 of table holds round 89 surface abrasion data and compares
Contrasting data from table 2 can draw：The outer bearing of component component 80 holds round 89 surfaces has a layer thickness to be
0.2 to 0.3 millimeter of evanohm hard wear-resistant layer, possesses superpower wearability.
The present invention has substantive distinguishing features following prominent and significant progressive effect.
12 section of permanent magnet in the present invention is isosceles trapezoid, and axial magnetic field gradually increases from inside to outside, it is to avoid magnetic field exists
There is saturation in inner radius, improve the utilization ratio of permanent magnet 12.Further, since stator core 26 and rotor core 11 and permanent magnet
Taper seat air gap being formed between 12, increasing air gap effective area, further improve permanent magnet 12 utilizes effect.
87 outside outer bearing of component flange is located among component component 80 in the present invention holds round 89 with component for adjusting ring
82 cylindrical between axiality be the error of 100 millimeters of unit sizes less than or equal to 0.01 millimeter, be similar to absolute concentric shafts.
In order to ensure the outer bearing on component component 80 hold round 89 and component for adjusting ring 82 cylindrical between there is high accuracy axiality, really
Protect machine shaft 40 and there is axiality relation also with vee-pulley 90, realize 90 steady coaxial rotating of vee-pulley.
Said structure achieves machine shaft 40 and fore bearing 25 and rear bearing 35 is only subjected to pure torsion, and three cuticles
It is but to be born by no inner-ring bearing 60 completely that vee-pulley 90 is reacted to produced radial load, is only operated at
On component component 80, it is entirely avoided the rotating shaft on machine shaft 40 bears radial load for overhanging section 46.
