Abstract
The utility model relates to a kind of motor dovetail slot segmental punching rotor, it comprises rotating shaft, gusset, segmental punching, gusset is located between rotating shaft and segmental punching, gusset one end is fixedly installed in rotating shaft, the other end end of described gusset is dove tail, the inner circle of described segmental punching is provided with the dovetail slot matched with gusset end dove tail, and the dove tail of gusset end embeds in the dovetail slot of segmental punching.The gusset of the utility model rotor and punching adopt dove tail damascene structures, can not produce the situation such as lug and skeleton spallation when rotor high-speed rotates, stable when ensure that rotor operation.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly relates to a kind of motor dovetail slot segmental punching rotor.
Background technology
Current domestic large-size horizontal motor rotor punching sheet all adopts fanning strip, fanning strip is laminated on hollow weldering muscle axle by burst, two ends are fixed with trim ring, by screw rod, fastening or wedge is sharp fastens firmly, during this structure is only adapted to, slow-revving motor, for the motor that middle and high speed rotates, if adopt this design, because root diameter is large, running speed is high, and the centrifugal force produced is very large, causes core stamping tab when motor runs up, serious likely causes skeleton spallation, and whole core stamping flies away from.Therefore, general large-scale high speed motor rotor core punching sheet is full circle sheet, but rotor iron core lamination adopts full circle sheet, and the stock utilization of punching is low, and material cost is high, simultaneously Making mold rather expensive.
Utility model content
The purpose of this utility model is to overcome above defect, provides a kind of rotor iron core lamination to be fanning strip, saves the stable motor dovetail slot segmental punching rotor of material, rotor structure.
The purpose of this utility model is by giving realization with following technical proposals, a kind of motor dovetail slot segmental punching rotor, it comprises rotating shaft, gusset, segmental punching, gusset is located between rotating shaft and segmental punching, gusset one end is fixedly installed in rotating shaft, the other end end of described gusset is dove tail, and the inner circle of described segmental punching is provided with the dovetail slot matched with gusset end dove tail, and the dove tail of gusset end embeds in the dovetail slot of segmental punching.
Described gusset end dove tail is fan-shaped convex tendon, and described dovetail slot is the scalloped recess matched with fan-shaped convex tendon.
Described gusset end dove tail is trapezoidal convex tendon, and described dovetail slot is the trapezoidal groove matched with trapezoidal convex tendon.
For ensureing that segmental punching can not move axially or loose, also comprise fastening screw, segmental punching is laminated on after on gusset one by one, described fastening screw by the segmental punching laminated from axially fastening into an entirety.
Technique effect of the present utility model is that the gusset of rotor and punching adopt dove tail damascene structures, can not produce the situation such as lug and skeleton spallation when rotor high-speed rotates, stable when ensure that rotor operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
With reference to accompanying drawing, a kind of motor dovetail slot segmental punching rotor, it comprises rotating shaft 3, gusset 2, segmental punching 1, gusset 2 is located between rotating shaft 3 and segmental punching 1, gusset 2 one end is fixedly installed in rotating shaft 3, the other end end of gusset 2 is dove tail 2-1, described gusset 2 end dove tail 2-1 is fan-shaped convex tendon, the inner circle of described segmental punching 1 is provided with the dovetail slot 1-1 matched with the dove tail 2-1 of gusset 2, described dovetail slot 1-1 is the scalloped recess matched with dove tail 2-1, the dove tail 2-1 of gusset 2 end embeds in the dovetail slot 1-1 of segmental punching 1, for ensureing that segmental punching 1 can not move axially or loose, also comprise fastening screw 4, segmental punching 1 is laminated on after on gusset 2 one by one, described fastening screw 4 by nut 5 by the segmental punching 1 laminated from axially fastening into an entirety.
Be more than an execution mode of the present utility model, the scope of the utility model application request protection has more than and is limited to described execution mode.Those skilled in the art directly derive or associate oher improvements and changes and all should think be included within protection range of the present utility model as fan-shaped convex tendon changes trapezoidal convex tendon etc. under the prerequisite of the spirit and design that do not depart from invention.
