Description
Technical field
The present invention relates to a kind of motor train unit locomotive definite purpose motor, have dual rigors to dimensional space and useful life, be specifically related to a kind of disk synchronous belt wheel motor manufacture method.
Background technology
The motor performance of EMU to trailer system has special rigors, and e.g., high pulling torque, low noise, bending resistance square and dispel the heat efficient etc., for this reason, European and American developed countries mostly adopt disc type electric machine.The motor of current application, its rated power is only 0.01 ~ 3kW, and starting torque is only 1.8 ~ 2.0 times of nominal torque, and therefore its application is very restricted.Through the retrieval of patent documentation, find " disc type outward turning spinner motor " patent of invention that the patent No. is 94228082.2, the magnetic pole that it adopts wide different length billot to laminate forms disc type internal stator iron core and outward turning dual-rotor structure.But starting torque is little, power is large not defect that this motor also exists.In addition, motor is except exporting with associated mode, and machine shaft only bears pure torsion.That the torsional forces mode being attended by radial moment of flexure exports time more, as: synchronous pulley etc.When equal-wattage and rotating speed, the machine shaft diameter of carrying bending synthesis is that more than the twice of the machine shaft diameter of carrying pure torsion just can guarantee there are enough coefficient of safetys.Therefore, in order to allow machine shaft bear bending moment force, have to machine shaft diameter to increase exponentially, finally cause series of malpractice: motor bearings linear velocity also increases exponentially, self in-fighting increases exponentially, and in-fighting causes caloric value to increase exponentially.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to be to provide a kind of disk synchronous belt wheel motor manufacture method, moment of flexure load shared by extension supporting component, to reduce the diameter dimension of machine shaft to adapt to this special occasions dimensional space and useful life being had to dual rigors of motor train unit locomotive.

The data of the radius run-out degree micron at table 1 fore bearing section 45 position compare
Contrasting data from table 1 can draw: it is after 80s that fore bearing 25 outer end have employed supporting member, and load suffered by fore bearing 25 alleviates wearing and tearing and reduces, cause fore bearing 25 the radius run-out degree at fore bearing section 45 position of machine shaft 40 of fixing micro-
Table 2 is that the outer bearing in the present invention props up and holds round 89 surfaces to have employed a layer thickness be that copper alloy hard wear-resistant layer and the outer bearing of 0.2 to 0.3 millimeter props up and hold round 89 surfaces and do not adopt a layer thickness to be that the corrosion resistant wear test data of the copper alloy hard wear-resistant layer of 0.2 to 0.3 millimeter compare.
The outer bearing of table 2 supporting member 80 props up and holds round 89 surface abrasion data and compare
Contrasting data from table 2 can draw: the outer bearing of supporting member 80 props up and holds round 89 surfaces and have a layer thickness to be the copper alloy hard wear-resistant layer of 0.2 to 0.3 millimeter, possesses superpower resistance to wear.
The present invention has following outstanding substantive distinguishing features and significant progressive effect:
1, component for adjusting ring 82 cylindrical and outer bearing prop up and hold round 89 employings and once clamped processing, ensure that component for adjusting ring 82 cylindrical and described outer bearing prop up the axiality relation holding round and have Pyatyi tolerance grade between 89, guarantee that electric machine main shaft 40 and synchronous pulley 90 also have axiality relation, realize synchronous pulley 90 steadily coaxial rotating;
2, machine shaft 40 and fore bearing 25 and rear bearing 35 need bear pure torsion, and synchronous belt produce radial load react to synchronous pulley 90 be can completely bear by no inner-ring bearing 60, only act on supporting member 80, the rotating shaft that completely avoid on machine shaft 40 bears radial load for overhanging section 46; Owing to meeting under the prerequisite of rated power, can accomplish that the limit is little by asking the diameter of machine shaft 40 in design, only bearing pure torsion, simultaneously, because supporting member 80 global shape belongs to hollow short tube, therefore structural rigidity is superpower, can bear larger radial load.Both combine, and present invention achieves and can do compact by whole motor size, can bear larger radial load again, run more reliable, thus extend the useful life of motor;
3, the outer bearing outside component flange 87 props up to hold round between 89 and component for adjusting ring cylindrical has axiality relation, guarantees that machine shaft 40 and synchronous pulley 90 also have axiality relation, realizes synchronous pulley 90 steadily coaxial rotating.Motor front end cover arranges supporting member 80, has shared all moment of flexure loads, made machine shaft 40 only bear pure torsion, machine shaft 40 diameter under equal-wattage can reduce half, finally realizes motor entirety and has breakthrough compact;
4, the outer bearing of supporting member 80 props up and holds round 89 surfaces and have a layer thickness to be the copper alloy hard wear-resistant layer of 0.4 to 0.6 millimeter, first through roughing and laser spraying before fine grinding, possesses superpower resistance to wear.
A key technology of the present invention is: it is that the error of 100 millimeters of unit sizes is less than or equal to 0.01 millimeter that the outer bearing among supporting member 80 outside component flange 87 props up the axiality held round between 89 and component for adjusting ring 82 cylindrical, is similar to absolute concentric shafts.Prop up to hold round between 89 and component for adjusting ring 82 cylindrical in order to ensure the outer bearing on supporting member 80 and there is high accuracy axiality.
