Abstract
The invention specially relates to a shaft removing method formotor rotor core and solves problems that series waste, long manufacture period and inconvenience for motor repair due to direct discard of prior damaged motor rotor cores. The method includes steps of (a) placing the a rotor core vertically, uniformly spraying grease on the lower end of a sleeve and sleeving a press ring with the sleeve; (b) pouring a small amount of kerosene into the sleeve; (c) placing press boards on press rings on two ends of a rotary shaft, wherein fastening pull rods are distributed between the two press boards and are provided with fastening nuts and butterfly-shaped gaskets are arranged between the fastening nuts and the adjacent press boards; (d) pressuring the rotor core to 20T and screwing the fastening nuts; (e) removing support blocks and pressuring with an upper pressure limit of 60T by using an oil press to make the rotary shaft withdraw and adding a round iron rod on the head of the rotary shaft to facilitate rotary shaft removal when the head of the rotary shaft moves to a position below the fastening pull rods. According to the invention, shaft removal of the rotor iron core is facilitated and a requirement for mass maintenance of rotor cores is met.
Description
Technical field
The present invention relates to electric machine iron core and axle separation method, be specially a kind of electric machine rotor iron core and move back axle method.
Background technology
Along with the successful introduction of external motor advanced manufacturing technology, high speed motor car is universal.The maintenance of rotor core, reclamation work normalization increasingly, make unshakable in one's determination separation with axle be one of its groundwork.That how to guarantee both quality and quantity moves back axle, effectively reduces the problem that percent defective becomes industry scientific worker general concern.The damage of motor-car motor CRH2/3/5, locomotive engine HXD2/3, HXN3 rotor core axle is more serious.
The mode that in the domestic and international motor same industry, the many employings of the type electric machine rotor iron core whole rotor product is directly scrapped, like this significant wastage is caused to iron-core lamination, pressing plate, end plate, rotating shaft, end ring, sliver, solder and solder flux etc., manufacturing cycle is long, waste is large, is unfavorable for reprocessing motor in time.
Summary of the invention
The present invention exists that waste is serious, the manufacturing cycle long to directly scrap after solving the damage of existing electric machine rotor iron core and is unfavorable for the problem that motor is reprocessed, and provides a kind of electric machine rotor iron core and moves back axle method.
The present invention adopts following technical scheme to realize: a kind of electric machine rotor iron core moves back axle method, adopt following steps: a, rotor core is vertically placed, and rotating shaft non-transmision end upward, sleeve lower end uniform application butter is enclosed within the trim ring of rotating shaft non-transmision end; Pour the immersion of a small amount of kerosene in b, sleeve into and be more than or equal to 24 hours; C, on the trim ring at rotating shaft two ends, all place pressing plate, and uniformly between two pressing plates be provided with some fastening pull rods through trim ring ventilation hole, fastening pull rod is screwed with the clamp nut be positioned at outside two pressing plates, between clamp nut and adjacent pressing plates, is provided with the butterfly gasket be enclosed within fastening pull rod; D, rotor core is hung on hydraulic press platform, back-up block placed by the trim ring of rotating shaft non-transmision end, back-up block is placed hydraulic press and be forced into 20T, clamp nut is tightened; E, remove back-up block, hydraulic press pressurizes, and requires that pressure is no more than 60T, rotating shaft is extruded, when shaft head retreats to fastening pull rod with upper/lower positions, increases circular iron staff rotating shaft exited at shaft head.
This moves back axle method and realizes the fixing of rotor core by the combination of pressing plate and pull bar, and the setting of elasticity butterfly gasket ensure that the pressure oscillation caused owing to expanding with heat and contract with cold in heating cooling procedure, ensure that packing unshakable in one's determination is constant, force value is determined under not changing the prerequisite of intrinsic sliver tensioner and rotor core natural frequency, and the heating-up temperature of iron core, and adopt volatility oil bath lubrication, conveniently move back axle, directly scrap after overcoming the damage of existing electric machine rotor iron core and have that waste is serious, the manufacturing cycle long and be unfavorable for the problem that motor is reprocessed.
Of the present invention move back that axle method is convenient to rotor core move back axle, fabrication cycle is short, time saving and energy saving, each a set of frock and reusable of only need dropping into, operating space is large, easy to maintenance, meet the needs that rotor core is reprocessed in enormous quantities, have that technique is simple, operating reliability is high and the advantage of good economy performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-rotor core, 2-rotating shaft, 3-sleeve, 4-trim ring, 5-pressing plate, 6-fastening pull rod, 7-clamp nut, 8-saucer washer.
Embodiment
A kind of electric machine rotor iron core moves back axle method, adopt following steps: a, rotor core 1 vertically placed, and rotating shaft 2 non-transmision end upward, is enclosed within the trim ring 4 of rotating shaft 2 non-transmision end by sleeve 3 lower end uniform application butter; Pour the immersion of a small amount of kerosene in b, sleeve 3 into and be more than or equal to 24 hours; C, on the trim ring 4 at rotating shaft 2 two ends, all place pressing plate 5, and uniformly between two pressing plates 5 be provided with some fastening pull rods 6 through trim ring 4 ventilation hole, fastening pull rod 6 is screwed with the clamp nut 7 be positioned at outside two pressing plates 5, between clamp nut 7 and adjacent pressing plates 5, is provided with the butterfly gasket 8 be enclosed within fastening pull rod 6; D, rotor core 1 is hung on hydraulic press platform, back-up block placed by the trim ring 4 of rotating shaft 2 non-transmision end, back-up block is placed hydraulic press and be forced into 20T, clamp nut 7 is tightened; E, remove back-up block, hydraulic press pressurizes, and requires that pressure is no more than 60T, rotating shaft 2 is extruded, when rotating shaft 2 head retreats to fastening pull rod 6 with upper/lower positions, increase circular iron staff rotating shaft exited at rotating shaft 2 head.
