Embodiment
Core of the present invention is to provide a kind of rotor for magneto, and this rotor can prevent from occurring between its each parts rotating.Another core of the present invention is to provide a kind of magneto comprising above-mentioned rotor.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
See the structure chart of the rotor that Fig. 1 and Fig. 2, Fig. 1 provide for the embodiment of the present invention, Fig. 2 be Fig. 1 viewed from P direction time cross-sectional schematic.
The rotor that the embodiment of the present invention provides, comprise the front trim ring 2 be set on successively in rotating shaft 1, rotor core and block 7, rear trim ring 6 is set in block 7 periphery and compresses rotor core, rotor core is provided with magnet slot, permanent magnet 4 embeds in magnet slot, the gap of permanent magnet 4 and magnet slot is provided with binding agent 3, also comprise back-up ring 9, the excircle of block 7 offers ring-shaped groove 71, back-up ring 9 may be stuck in ring-shaped groove 71, the excircle of back-up ring 9 is provided with the breach 91 corresponding with the radial installing hole of rear trim ring 6, the head being arranged on the fixed part 8 in the installing hole of rear trim ring 6 may be stuck in the breach 91 of back-up ring 9.
The rotor that the embodiment of the present invention provides, can ensure that fixed part 8, back-up ring 9 and block 7 connect as a whole, thus prevent between each parts of permanent magnet machine rotor and relatively rotate, and relative to the existing mode being provided with bolt and rotating to prevent each parts of rotor on block 7, above-mentioned the axial arranged length that effectively can shorten permanent magnet machine rotor is set, realizes the lightweight of motor.
Above-mentioned magnet slot can be arranged on the inside of rotor core, also can be arranged on the surface of rotor core.If when magnet slot is arranged on the inside of rotor core, when fill in magnet slot for permanent magnet 4 and magnet slot are bonded together binding agent time, the access aperture entered for binding agent can be provided with on front trim ring 2; When magnet slot is arranged on rotor core surperficial, binding agent can directly enter from the surface of rotor core.S and N in Fig. 2 is the pole orientation of permanent magnet 4.Front trim ring 2 and rear trim ring 6 are processed to form by non-permeable material.
Fixation portions part 8 is for fixing rear trim ring 6, block 7 and back-up ring 9, and can ensure relative motion not to occur between each parts in rotor, fixed part 8 can be screw, bolt or pin.
Above-mentioned rotor core stacks by tack silicon steel sheet 5 is sticky the hollow cylinder formed.
Above-mentioned tack silicon steel sheet 5 is adopted to form rotor core, instead of adopt existing rotor punching, because existing rotor punching needs repeatedly to be inserted on machine shaft, then laminate in rotating shaft, and by miscellaneous part axial restraint, production process is various, tack silicon steel sheet 5 can at constant temperature, mutually pasted together by pressure under constant voltage, then entirety is enclosed within rotating shaft 1, relative to rotor punching of the prior art, production process is relatively simple, and tack silicon steel sheet 5 is bonded together by the cohesive force of self, improve the efficiency and the mechanized continuous productive process being beneficial to magneto that manufacture magneto.
