Abstract
The utility model discloses a rare earth permanent magnet generator rotor sheet, which is formed by machining wastes produced by punching stators of same specifications. When a punching mold is designed, molds of two sheets are designed into a combined mold, namely, a rotor sheet and a stator sheet can be machined once in the punching process. The rotor sheet comprises a rotor sheet body, wherein the round edge of the rotor sheet body is symmetrically provided with a group of magnetic shoe mounting holes, 8 circular holes are symmetrically formed in the circumference of the magnetic shoe mounting holes, a circular hole is formed in the center of the rotor sheet body, and a semicircular groove is formed in the circumference of the circular hole. According to the rare earth permanent magnet generator rotor sheet disclosed by the utility model, the rotor sheet is adopted instead of a round steel material used by the original rare earth permanent magnet generator rotor, therefore the raw material utilization rate is greatly improved, the rotor machining complexity is also reduced, the product process is improved and the product cost is reduced.
Description
Technical field
The utility model belongs to the rare earth permanent-magnetic generator field, specifically, relates to a kind of rare-earth permanent magnet generator rotor punching.
Background technology
Along with the development of rare earth permanent-magnetic generator technology, its product more and more is subject to the welcome in market, and demand is also in continuous increase.It is that raw material are processed into that the rotor core of present rare-earth generator all adopts round steel, and processing cost is high, and the raw-material waste that processing causes is also taught greatly, and when this rotor core was made rotor assembly more simultaneously, technological requirement was higher.And the used stator punching of rare-earth generator all adopts silicon steel sheet to make, and can produce a large amount of waste materials after the stator punching processing, and the general difficulty of these waste materials finds suitable product with it utilization, and general all as waste disposal, waste greatly.
Summary of the invention
The utilance of raw materials and reduction product cost when producing for improving rare earth permanent-magnetic generator, a kind of rare-earth permanent magnet generator rotor punching that the utility model provides, not only the used round steel of alternative former rotor material is processed the rear waste material that produces but also can take full advantage of stator punching.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rare-earth permanent magnet generator rotor punching, adopt the waste material of the stator punching generation of same specification to process, namely utilize the gap that exists between generator amature and the stator, Design of Dies with two kinds of punchings when the design Lamination mould becomes compound die, can time processing go out rotor punching and stator punching when punching.This rotor punching comprises the rotor punching body, and the round edge symmetry of rotor punching body has one group of magnetic shoe installing hole, is arranged with 8 circular holes around described magnetic shoe installing hole, and the aperture is 3mm.
Described a kind of rare-earth permanent magnet generator rotor punching is provided with a circular hole, the half slot that it is 2.5mm that the circumference of circular hole is provided with a radius at the center of this rotor punching body.
Adopt such scheme, the beneficial effects of the utility model are: the stator punching of employing same specification adds the waste material that produces man-hour and is processed into rotor punching, substituted the used round steel material of former rare-earth permanent magnet generator rotor, when greatly improving utilization rate of raw materials, also reduced the complexity of rotor machining, improve Product Process, reduced product cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Accompanying drawing is the structural representation of a kind of rare-earth permanent magnet generator rotor punching of the utility model.
Embodiment
As shown in drawings, a kind of rare-earth permanent magnet generator rotor punching, comprise rotor punching body 1, the round edge place symmetry of this rotor punching body 1 has one group of magnetic shoe installing hole 2, the used magnetic shoe of rare-earth generator is fixed in this magnetic shoe installing hole 2, magnetic shoe can be avoided when generator operation and stator inner wall occurs to wipe and bumps, the break infringement of rear generation of magnetic shoe can be effectively prevented simultaneously.Be symmetrical arranged 8 circular holes 3 around described magnetic shoe installing hole 2, this circular hole aperture is 3mm, for formation rare-earth permanent magnet generator rotor that rotor punching is riveted together.The center of rotor punching body 1 is provided with a centre bore 4, at the circumference of the centre bore semicircle orifice 5 that to have a radius be 2.5mm.
Claims (2)
1. rare-earth permanent magnet generator rotor punching, adopt the waste material of the stator punching generation of same specification to process, substitute the used material of former rare-earth permanent magnet generator rotor---round steel, this rotor punching comprises the rotor punching body, it is characterized in that, the round edge symmetry of rotor punching body has one group of magnetic shoe installing hole, is arranged with 8 circular holes around described magnetic shoe installing hole, and the aperture is 3mm.
2. a kind of rare-earth permanent magnet generator rotor punching according to claim 1 is characterized in that, the center of rotor punching body is provided with a circular hole, the half slot that it is 2.5mm that the circumference of circular hole is provided with a radius.
