Abstract
The invention discloses a two-pole winding motor rotor ring pressing structure. The front end and the rear end of a rotor sheet are tightly pressed by rotor end plates and rotor pressing rings to be fixed to a shaft, the rotor pressing ring at one end is fixed by an upper blocking shoulder of the shaft, and the rotor pressing ring at the other end is arranged on the shaft and is fixed by an firmly welded arc key. The shaft is sleeved with a coil support in a heating mode, rotor coils are sequentially embedded in grooves of the rotor sheet, teeth are evenly distributed on the outer circumstance of each rotor pressing ring, and a boss with the thickness of 1mm and the height of 20mm is arranged at the outer circle position of each tooth. The two-pole winding motor rotor ring pressing structure is reasonable in structure and ingenious in design. Under the condition that efficiency, the power factor, vibration and the like of an electric motor meet the requirements, a structure that many teeth are formed by cutting the outer circles of the rotor pressing rings and the bosses are added at the positions of the tooth outer circles is adopted. Meanwhile, a part installation and fixing method is optimized, and the tooth loosening situation of the rotor sheet is greatly improved.
Description
Technical field
The invention belongs to motor technology field, specifically relate to a kind of the two poles of the earth coiling motor rotor ring pressing construction.
Background technology
In prior art, the two poles of the earth coiling electric motor designs, manufacture difficulty is large, with high content of technology, and the producer of domestic capable this type of motor of production is few.Bipolar machine rated speed is close to 3000 revs/min, and rotating speed is high, and material stress allowable is had relatively high expectations, and also has noise, vibration, ventilation and heat etc. a series of needs to consider a problem.
The two poles of the earth coiling is at present high-power, pot-motor application demand is increasingly extensive, motor rotor core is divided into a lot of lamination sections, the punching that point is welded with tooth pressing plates (or vent segment) has been placed at rotor core section two ends, i.e. rotor end plates, and rotor pressing ring has been placed at rotor end plates two ends.Power of motor is large, rotating speed is high, and iron core is also longer, and the longer rotor core of iron core easily produces tooth pine phenomenon.After machine operation, rotor core high-speed cruising also produces disturbance, and tooth pine phenomenon does not solve early stage, can produce very large hidden danger, therefore needs a kind of rotor pressing ring structure that can prevent tooth pine.
Summary of the invention
The object of the invention is to overcome weak point of the prior art, thereby a kind of the two poles of the earth coiling motor rotor ring pressing construction is provided, guaranteeing that motor efficiency, power factor, vibration etc. all meet the requirements of under prerequisite, improve rotor punching tooth pine phenomenon.
Technical scheme of the present invention is as follows:
A coiling motor rotor ring pressing construction, is fixed on axle on after compressing before and after rotor punching by rotor end plates and rotor pressing ring, and the rotor pressing ring of one end is fixing by the shoulder that performs of axle, the rotor pressing ring of the other end be placed on axle also electric welding firmly arc key fix; Coil brace hot jacket is on axle; Rotor coil embeds in the groove of rotor punching successively; On the excircle of rotor pressing ring, be evenly distributed with tooth, it is 1mm that the cylindrical place of tooth has thickness, is highly the boss of 20mm.
Useful technique effect of the present invention is:
The present invention is rational in infrastructure, designs ingeniously, in motor efficiency, power factor, vibration etc., all meets the requirements of under prerequisite, employing is cut a lot of teeth at rotor pressing ring cylindrical, tooth cylindrical place increases the structure of boss, and optimization component is installed fixed form simultaneously, significantly improves rotor punching tooth pine situation.The theoretical analysis and experimental study prove, rotor pressing ring cuts the outer round belt boss structure of tooth, by same model motor contrast verification, adopts this effect structure obvious, can greatly improve rotor punching tooth pine phenomenon.
Advantage of the present invention will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of rotor pressing ring
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, rotor punching 6 front and back are fixed on axle 1 after compressing by rotor end plates 5 and rotor pressing ring 4, form an integral body, and this whole one end is fixing by the shoulder that performs of axle 1, and the other end is fixing by arc key 7.Arc key 7 needs electric welding firm after putting on axle 1.Coil brace 2 hot jackets are on axle 1, and rotor coil 3 embeds in the groove of rotor punching 6 successively.
As shown in Figure 2, the cylindrical of rotor pressing ring 4 is with a lot of teeth 8.For guaranteeing the electric clearance uniformity of rotor coil 3 and rotor pressing ring tooth 8, first processing plane, then line cutting teeth 8, the equal indicative of assurance tooth 8.
As shown in Figure 3, the cylindrical place of the tooth 8 of rotor pressing ring 4 has boss 9, and the thickness of boss 9 is 1mm, is highly 20mm.After motor laminates by the rotor pressing ring 4 with tooth 8, the 1mm thickness of boss 8 is tightly pushed down the cylindrical of rotor punching 6, and the 20mm of boss 8 highly guarantees that boss is not yielding.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
