Abstract
The present invention is specially that a kind of electric machine rotor iron core moves back axle method, solve directly scrapped after the damage of existing electric machine rotor iron core in the presence of waste seriously, manufacturing cycle length and be unfavorable for the problem of motor is reprocessed.A, rotor core is disposed vertically, the uniform coating butter in sleeve lower end is enclosed on trim ring；A small amount of kerosene immersion is poured into b, sleeve；C, place to be uniformly arranged between pressing plate, and two pressing plates on fastening pull rod, fastening pull rod on the trim ring at rotating shaft two ends and be screwed with clamp nut, butterfly gasket is provided between clamp nut and adjacent pressing plates；D, rotor core is forced into 20T, clamp nut is tightened；E, remove support block, hydraulic press pressurization, it is desirable to which pressure is no more than 60T, and rotating shaft is extruded, when shaft head retreats to below fastening pull rod position increases circular iron staff in shaft head and exits rotating shaft.What the present invention was easy to rotor core moves back axle, meets the need for rotor core high-volume reprocesses.
Description
Technical field
The present invention relates to electric machine iron core and axle separation method, specially a kind of electric machine rotor iron core moves back axle method.
Background technology
With the successful introduction of external motor advanced manufacturing technology, high speed motor car has been popularized.The maintenance of rotor core, reprocess
Work normalization increasingly, and it is one of its groundwork to make unshakable in one's determination separated with axle.That how to guarantee both quality and quantity moves back axle, effectively reduces waste product
The problem of rate turns into industry scientific worker's general concern.Motor-car motor CRH2/3/5, locomotive engine HXD2/3, HXN3 rotor iron
The damage of heart axle is more serious.
Directly scrapped using whole rotor product more than the type electric machine rotor iron core during domestic and international motor is of the same trade
Mode, so causes significant wastage, manufacture week to iron-core lamination, pressing plate, end plate, rotating shaft, end ring, sliver, solder and solder flux etc.
Phase is long, wastes big, is unfavorable for reprocessing motor in time.
The content of the invention
The present invention in order to solve directly to scrap after the damage of existing electric machine rotor iron core in the presence of waste seriously, manufacturing cycle length and
It is unfavorable for the problem of motor is reprocessed and moves back axle method there is provided a kind of electric machine rotor iron core.
The present invention adopts the following technical scheme that realization：A kind of electric machine rotor iron core moves back axle method, using following steps：
A, rotor core is disposed vertically, and rotating shaft non-transmision end is upward, it is non-drive that the uniform coating butter in sleeve lower end is enclosed on into rotating shaft
On the trim ring at end；A small amount of kerosene immersion is poured into b, sleeve to be more than or equal to 24 hours；C, place on the trim ring at rotating shaft two ends
It is uniformly arranged on some fastening pull rods through trim ring air vent, fastening pull rod and is screwed with positioned at two between pressing plate, and two pressing plates
Clamp nut on the outside of pressing plate, is provided with the butterfly gasket being enclosed on fastening pull rod between clamp nut and adjacent pressing plates；D, general
Rotor core is hung on oil pressure machine platform, is placed on the trim ring of rotating shaft non-transmision end and is placed oil pressure in support block, support block
Machine is forced into 20T, and clamp nut is tightened；E, remove support block, hydraulic press pressurization, it is desirable to which pressure is no more than 60T, by rotating shaft pressure
Go out, when shaft head retreats to below fastening pull rod position, increase circular iron staff in shaft head and exit rotating shaft.
This moves back the fixation that axle method realizes rotor core by the combination of pressing plate and pull bar, and elastic butterfly gasket is set
Put the pressure oscillation that ensure that and caused in heating cooling procedure due to expanding with heat and contract with cold, it is ensured that compactness unshakable in one's determination is constant, does not change
Intrinsic sliver tensioner is waved with determining pressure value, and heating-up temperature unshakable in one's determination on the premise of rotor core intrinsic frequency, and using
Hair property oil bath lubrication, conveniently moves back axle, overcome directly scrapped after the damage of existing electric machine rotor iron core it is all in the presence of serious, manufacture is wasted
Phase length and it is unfavorable for the problem of motor is reprocessed.
Of the present invention to move back the axle that moves back that axle method is easy to rotor core, fabrication cycle is short, time saving and energy saving, only needs to throw every time
Enter a set of frock i.e. reusable, operating space is big, easy to maintenance, meet the need for rotor core high-volume reprocesses, have
Technique is simple, operating reliability is high and good economy performance advantage.

Upward, the uniform coating butter in the lower end of sleeve 3 is enclosed on the trim ring 4 of the non-transmision end of rotating shaft 2 for driving end；Poured into b, sleeve 3 few
Kerosene immersion is measured to be more than or equal to 24 hours；C, place between pressing plate 5, and two pressing plates 5 uniform on the trim ring 4 at the two ends of rotating shaft 2
It is provided with the clamp nut being screwed with some fastening pull rods 6 through the air vent of trim ring 4, fastening pull rod 6 positioned at the outside of two pressing plate 5
7, the butterfly gasket 8 being enclosed on fastening pull rod 6 is provided between clamp nut 7 and adjacent pressing plates 5；D, rotor core 1 hung
On oil pressure machine platform, placement hydraulic press in support block, support block is placed on the trim ring 4 of the non-transmision end of rotating shaft 2 and is forced into
20T, clamp nut 7 is tightened；E, remove support block, hydraulic press pressurization, it is desirable to which pressure is no more than 60T, and rotating shaft 2 is extruded, when
The head of rotating shaft 2 retreats to fastening pull rod below 6 during position, increases circular iron staff on the head of rotating shaft 2 and exits rotating shaft.
