Abstract
The utility model provides an iron core of motor rotor with spiral air-flow groove. The iron core 1 is an integral structure with flat bar-shaped steel belt 4 which is provided with a neck gear 3 winding through an auger type flat jointing, the external periphery of the iron core 1 is provided with an auger type air slide 5, the two ends of the iron core 1 is fixedly jointed with an end cap 6, and the end cap 6 is fixedly connected with an axle 2. The utility model changes the traditional stamping steel plate fundamentally, which overlaps the steel plates in order to form an iron core, so the raw material is saved, and the manufacturing cost is reduced. The utility model can accomplish mechanize flow operation, overcome the anthropogenic factors, steady the production quality and increase the working efficiency, the opening of the auger type flow slot 5 assures the air flowing between the rotator and the stator, which is profitable for the motor cooling and prolonging the service life of the motor.
Description
Affiliated technical field
The utility model relates to the motor rotor core production technical field.
Background technology
Existing so far more than the 200 year history of motor development, the moulding process of its rotor core does not all change always, that is to say: get the monolithic steel disc by common punch press punching, get rotor core base just through artificial lamination, through the welding or rivet semi-finished product, get finished product through lathe turning again.Mainly there is following drawback in the rotor core that makes through conventional method: the one, and the monolithic steel disc stays a large amount of leftover pieces after the punch press punching, and the waste of material that causes is very huge.As calculated, the waste of the weight of every leftover pieces reaches 45 percent of full wafer steel weight.The 2nd, what piecemeal steel disc will be by artificial slices is superimposed, and the cost plenty of time, wherein human factor is many, causes the quality stability of finished product poor, and work efficiency is low.
The utility model content
The utility model fundamentally changes the moulding process of motor rotor core, and a kind of motor rotor core with spiral air flow groove is provided, and has overcome above-mentioned all weak points that present motor rotor core product exists very effectively.
The utility model is for solving its technical problem, adopted following technical scheme: motor rotor core with spiral air flow groove, comprise iron core 1, rotating shaft 2 etc., architectural feature shows: iron core 1 is an overall structure of being reeled and forming through spiral flat applying by a flat strip steel band 4 that has a jet-bedding tooth 3, the outer garden of iron core 1 offers helical flow groove 5, and the two ends of iron core 1 are applying end cap 6 fixedly, between end cap 6 and the rotating shaft 2 for fixedlying connected.Fixedly connected between end cap 6 and the rotating shaft 2 is that rectangular spline is connected or stationary fit connects or the like.
The beneficial effects of the utility model are: overcome the huge wastage of material that the blocks of punching press of present rotor core is caused, reduced production cost; Accessory production and combination forming are all realized mechanized continuous productive process, have reduced many human factors, help the raising of product quality, have reduced producers and other producing cost simultaneously, help enterprise and increase economic efficiency; The helical flow groove 5 that the outer garden of iron core is offered can make between rotor and the stator and produce circulation of air, reduces motor and heats up, and has prolonged the time and the useful life of motor continuous operation; Rotor core after the moulding is a hollow body, can reduce starting current, makes the electric elements supporting with it not fragile.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to cutaway view.
Fig. 4 is the front view of flat strip steel band 4.
Among the figure, 1, iron core, 2, rotating shaft, 3, the jet-bedding tooth, 4, flat strip steel band, 5, the helical flow groove, 6, end cap.
Embodiment
Iron core raw material of the present utility model, promptly flat strip steel band 4, it has jet-bedding tooth 3.In spiral flat applying winding process, two tooth limits of jet-bedding tooth 3 realize overlapping, so following horizontal line of steel band 4 just become the inner ring of hollow garden cylindricality iron core, and the last bar horizontal line of steel band 4 has just become the outer ring of hollow garden cylindricality iron core.The length of steel band 4 is determined according to the length of iron core 1.In fact Fig. 4 can be regarded as the expanded view of iron core 1 under the situation of not offering helical flow groove 5 as yet.Need to allocate into simultaneously end cap and rotating shaft in winding process, the inner face of the two sides of steel band 4 and two end caps is all answered gluing.By static pressure equipment hydrostatic profile and after treating the gluing drying, go up the spiral airslide 5 of lathe turning again, finally obtain the utility model finished product.
