Abstract
The utility model discloses a rotor piece for permanent -magnet machine, it includes rotor piece body, seted up the centre bore on the rotor piece body, wherein, set up the mounting hole that a plurality of is used for installing the magnet steel on being close to the same circumference of its outer fringe on the rotor piece body, just offer the recess that is used for reducing the magnetic leakage in the outer fringe of rotor piece body between adjacent two mounting holes, a plurality of fixed orifices and ventilation hole have been seted up on the rotor piece body. Above -mentioned a rotor piece for permanent -magnet machine installs the magnet steel in the mounting hole through set up the mounting hole on the lamellar body, ensures the magnet steel and can not follow the lamellar body and drop, has improved the fail safe nature of the whole operation of permanent -magnet machine greatly.
Description
Technical field
The utility model relates to a kind of magneto, particularly relates to a kind of rotor sheet for magneto.
Background technology
At present, the magnet steel of traditional magneto is all be adhered in the outer rim of rotor sheet, this bonding mode is also unreliable, because in rotor rotation process there is larger centrifugal force in itself, if the adhesive effect that simultaneously bonded adhesives of later adhesive magnetic steel grown service time by motor is certain to reduce, so just there is the risk that magnet steel comes off, and magnet steel is just easily adsorbed on the miscellaneous part of magneto once come off because it has magnetic force, affect normal use and the security reliability of whole magneto.
Utility model content
The purpose of this utility model is to provide a kind of rotor sheet for magneto, and it can guarantee that magnet steel can not come off from rotor sheet, to solve the problems referred to above in prior art, magnetic steel of magnetoelectric machine mounting means existed.
For reaching this object, the utility model by the following technical solutions:
A kind of rotor sheet for magneto, it comprises rotor sheet body, described rotor sheet body offers centre bore, wherein, described rotor sheet body circumferentially offers several installing holes for mounting magnetic steel near its outer rim same, and the groove outer rim of described rotor sheet body offered between adjacent two installing holes for reducing leakage field, described rotor sheet body offers several fixing holes and ventilation hole.
Especially, described installing hole is shoulder hole, comprise external holes and internal holes, the whole height of described installing hole coordinates the thickness of magnet steel to arrange, the width of described external holes is less than the width of described internal holes, and the width of the width fits magnet steel of described external holes is arranged, this structural design can be convenient to magnet steel and be installed in described installing hole.
Especially, described groove is set to arc-shaped structure.
Especially, the number of described installing hole is set to 16, and equi-spaced apart is distributed on described rotor sheet body.
Especially, described fixing hole and ventilation hole are arranged at the circumferentially same of rotor sheet body, and circumferentially, arrange a ventilation hole between adjacent two fixing holes, the aperture of described ventilation hole is greater than the aperture of described fixing hole to described fixing hole uniform.
The beneficial effects of the utility model are, compared with prior art the described rotor sheet for magneto by offering installing hole on lamellar body, magnet steel is installed in installing hole, guarantees that magnet steel can not come off from lamellar body, substantially increase the security reliability of magneto overall operation.
