Description
Technical field
This utility model is related to technical field of generators and in particular to the connection of a kind of Nd-Fe-B magnet steel and rotor core is tied
Structure.
Background technology
Existing be Nd-Fe-B magnet steel with rotor core connection when, Nd-Fe-B magnet steel is arc strip, and rotor core is cylinder
Shape, at least two pieces of Nd-Fe-B magnet steel, the Inner arc of Nd-Fe-B magnet steel is mated with the external arc of rotor core, and is symmetricly set on
Outside the left and right of rotor core.Nd-Fe-B magnet steel is fixed on rotor core by way of radial direction plays screw.Existing rotor
Iron core processes according to steel part, and it is even easy to play screw, is formed by stacking according to punching and cannot process screw thread.
Utility model content
This utility model aims to provide the attachment structure of a kind of Nd-Fe-B magnet steel and rotor core it is not necessary to radially beat spiral shell
Nail, easier for installation quick.
For this reason, the technical scheme that this utility model is adopted is：A kind of Nd-Fe-B magnet steel and the attachment structure of rotor core,
Described Nd-Fe-B magnet steel is arc strip, and rotor core is cylinder, at least two pieces of Nd-Fe-B magnet steel, the inner circle of Nd-Fe-B magnet steel
Arc is mated with the external arc of rotor core, and is symmetricly set on outside the left and right of rotor core, the inner side of described Nd-Fe-B magnet steel
It is provided with swallow-tail form projection, the outside of rotor core is provided with the dovetail groove mating with swallow-tail form projection, described swallow-tail form
Projection prevents from dovetail groove rotating along slipping into of diameter parallel, and before and after rotor core, both sides are respectively arranged with pressing plate, and lead to
Cross and be bolted to rotor core thus preventing from moving axially Nd-Fe-B magnet steel compression, finally realize Nd-Fe-B magnet steel and rotor
The installation of iron core.
Preferred as such scheme, described Nd-Fe-B magnet steel is four pieces, one group two-by-two, from appropriate number of neodymium iron boron
Magnet steel is it is ensured that performance reduce manufacturing cost.
Further, described rotor core is formed by stacking using punching, and dovetail groove directly rushes in punching rotor punching
System forms.
The beneficial effects of the utility model：Anti-rotation is connected using dovetail groove, and prevents from moving axially with reference to platen clamp, real
Showed Nd-Fe-B magnet steel and rotor core is reliably connected it is not necessary to radially play screw, easier for installation quick, lifting production
Efficiency, is particularly suitable for using using the rotor core that punching is formed by stacking.Need to go during using Nd-Fe-B magnet steel processing Inner arc
The waste part processing swallow-tail form removed is raised, and rotor core is formed by stacking using punching, compares steel part machine addition originally lower.
