Abstract
The invention relates to a large asynchronous motor rotor fanning strip lamination structure comprising a rotor fanning strip, a tie bolt, a stop pin, a rotor clamping ring, a rotor ventilation trough plate, a rotor end plate and an inclined key, wherein the rotor fanning strip, the rotor fanning ventilation trough plate and the rotor end plate are positioned by pins during the laminating process; and after the rotor fanning strip and the like are laminated, a screw tightly pulls the rotor fanning strip and the rotor clamping ring, and the inclined key is subject to thermal beating. Screw holes and pin holes are punched on the rotor fanning strip, the number of the pin holes is two times of that of the screw holes, a gap between each screw hole and the screw is 0.3-0.5 mm, and a gap between each pin hole and the pin is 0.1 mm. The invention has simple and compact structure and obvious acting effect; under the condition of not changing a structural material and ensuring qualified motor magnetic property characteristics, the laminating difficulty of the rotor fanning strip is lowered, and the reliability of the rotor is improved.
Description
Technical field
The present invention relates to the rotor fanning strip, relate in particular to the laminated structure of large-scale threephase asynchronous machine rotor fanning strip.
Background technology
When large-size asynchronous motor surpasses 1200mm (or 1250mm) when root diameter.Because be subjected to the restriction of silicon steel sheet width dimensions, rotor core need be made fan-shaped lamination press mounting structure, one of iron core formation behind the closed assembly is circular.When rotor rotates, need bear under punching self and the action of centrifugal force that coil produced in the rotor core groove, laminated core should keep globality and and rotor field spider (or welding axle) between remain stop enough in the required magnitude of interference of moment of friction between transmitter shaft and the rotor core.The traditional structure of large-size asynchronous motor uses the screw rod location, and the gap between screw rod and screw hole is 0.1mm, and this mechanism exists rotor fanning strip suit work efficiency low, and screw rod takes place sometimes bending slightly, situation that can not lamination after above being stacked to.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of large-size asynchronous motor rotor fanning strip laminated structure is provided, under assurance motor magnetic property characteristic acceptance condition, reduced the difficulty that the rotor fanning strip laminates, and improved the reliability of rotor.
Technical scheme of the present invention is as follows:
Large-size asynchronous motor rotor fanning strip laminated structure, comprise rotor fanning strip, screw rod, hex nut, rotor end plates, pin, rotor ventilation frid, rotor pressing ring, taper key and rotor field spider, described rotor pressing ring puts together on the rotor field spider, rotor end plates, rotor ventilation frid and rotor fanning strip by pin location be laminated on the rotor field spider, between two rotor pressing rings, screw rod is among the rotor end plates that laminates, rotor ventilation frid and rotor fanning strip, and hex nut is anchored on the screw rod two ends; Taper key is fastening with the structural entity between above-mentioned two rotor pressing rings.
Its further technical scheme is: described rotor fanning strip upper punch is shaped on the screw hole that is used to wear screw rod, and the pinhole that is used to wear pin; The number of described pinhole is 2 times of screw hole, and the both sides of each screw hole respectively are provided with a pinhole.Gap between described screw hole and screw rod is 0.3～0.5mm, and the gap between pinhole and pin is 0.1mm.
And its further technical scheme is: the length of described pin is 200mm～300mm, comprises two kinds of different length, and the length pin is staggered to be placed at interval, and the length pin is placed continuously, between do not have the gap.
Useful technique effect of the present invention is:
The present invention is simple in structure, compact, and action effect is obvious: under the situation that does not change structural material, under assurance motor magnetic property characteristic acceptance condition, reduced the difficulty that laminates of rotor fanning strip, and improved the reliability of rotor.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes rotor fanning strip 1, screw rod 2, hex nut 3, rotor end plates 4, pin 5, rotor ventilation frid 6, rotor pressing ring 7, taper key 8 and rotor field spider 9.Rotor pressing ring 7 puts together on the rotor field spider 9.Rotor end plates 4, rotor ventilation frid 6 and rotor fanning strip 1 by pin 5 location be laminated on the rotor field spider 9, between two rotor pressing rings 7.Screw rod 2 is among the rotor end plates 4 that laminates, rotor ventilation frid 6 and rotor fanning strip 1, and hex nut 3 is anchored on screw rod 2 two ends.Taper key 8 is fastening with the structural entity between above-mentioned two rotor pressing rings 7.
Lamination process is as follows: earlier a rotor pressing ring 7 is put together on the rotor field spider 9, a rotor end plates 4 is laminated on the rotor field spider 9, then rotor ventilation frid 6 and rotor fanning strip 1 alternately are laminated on the rotor field spider 9, laminate a rotor end plates 4 again, locate with pin 5 when laminating, put another one rotor pressing ring 7 after laminating, with the rotor core tension that screw rod 2 and hex nut 3 will laminate, heat is beaten taper key 8 then.
As shown in Figure 2, rotor fanning strip 1 upper punch is shaped on the screw hole 10 that is used to wear screw rod 2, and the pinhole 11 that is used to wear pin 5.The number of pinhole 11 is 2 times of screw hole 10, and the both sides of each screw hole 10 respectively are provided with a pinhole 11.The gap that screw hole 10 and screw rod are 2 is 0.3～0.5mm, and the gap that pinhole 11 and pin are 5 is 0.1mm.
As shown in Figure 3, it is long that pin 5 length should be made 200mm～300mm, and adopt two kinds of length, and place at have strong market potential sub-5a and the staggered interval of short pin 5b.Have strong market potential sub-5a and short pin 5b places continuously, between do not have the gap.And the sub-5a that has strong market potential in adjacent two pinholes 11 is different with arranging of short pin 5b, and pin is staggered mutually at the weld of circumferencial direction, reaches balance.
