Abstract

The utility model relates to a neodymium iron boron magnetic steel and rotor core's connection structure, neodymium iron boron magnetic steel's interior circular arc matees with rotor core's outer circular arc, the symmetry sets up the outside about rotor core, neodymium iron boron magnetic steel's inboard is provided with the swallow -tail form arch, rotor core's the outside is provided with the dovetail groove who matches with the swallow -tail form arch, the swallow -tail form is protruding to slide in preventing rotation in the dovetail groove along the axis is parallel, both sides are provided with the clamp plate respectively around the rotor core, thereby and compress tightly neodymium iron boron magnetic steel at rotor core through the bolt fastening and prevent axial displacement, finally realize neodymium iron boron magnetic steel and rotor core's installation. Do not need radially to play the screw, install convenient and fast more, promote production efficiency, be particularly suitable for adopting the rotor core who is formed by stacking towards the piece to use.

Description

Nd-Fe-B magnet steel and the attachment structure of rotor core

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.

Brief description

Fig. 1 is structural representation of the present utility model (not including pressing plate).

Fig. 2 is the inner side view of Nd-Fe-B magnet steel.

Fig. 3 is the upward view of Fig. 2.

Specific embodiment

Below by embodiment and combine accompanying drawing, the utility model is described in further detail:

In conjunction with shown in Fig. 1 Fig. 3, the attachment structure of a kind of Nd-Fe-B magnet steel and rotor core, Nd-Fe-B magnet steel 1 is arc Bar, rotor core 2 is cylinder.At least two pieces of Nd-Fe-B magnet steel 1, preferably four pieces of Nd-Fe-B magnet steel 1, one group two-by-two, but It is not limited to four pieces, occur in even number, belong to the common knowledge of this area.

The Inner arc of Nd-Fe-B magnet steel 1 is mated with the external arc of rotor core 2, and is symmetricly set on a left side for rotor core 2 Right outside.

The inner side of Nd-Fe-B magnet steel 1 is provided with swallow-tail form projection 1a, and the outside of rotor core 2 is provided with and swallow-tail form projection The dovetail groove 2a of 1a coupling.Swallow-tail form projection 1a prevents from dovetail groove 2a rotating along slipping into of diameter parallel.Rotor Before and after iron core 2, both sides are respectively arranged with pressing plate (not shown), and are bolted on rotor core 2 thus by neodymium iron boron Magnet steel 1 compression prevents from moving axially, and finally realizes the installation of Nd-Fe-B magnet steel 1 and rotor core 2.It is provided with rotor core 2 The bolt through-hole 2b of pressing plate is installed.

Preferably, rotor core 2 is formed by stacking using punching, the dovetail groove 2a directly punching in punching rotor punching Form.
