Technical field
The utility model relates to the rotor fanning strip, relates 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.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of large-size asynchronous motor rotor fanning strip laminated structure, under assurance motor magnetic property characteristic acceptance condition, reduced the difficulty that the rotor fanning strip laminates, and improved the reliability of rotor.
The technical solution of the utility model 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 utility model is:
The utility model 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.
