Abstract
The utility model provides a magnetic-shoe built-in permanent-magnetic motor rotor, which comprises a rotating shaft and a rotor, and is characterized in that: the rotor is formed by press mounting a plurality of rotor punching sheets with square slotted holes and screw rod holes, wherein the square slotted hole and the screw rod hole of each rotor punching sheet are correspondently communicated with each other to form a square groove for mounting a magnetic shoe and a screw rod hole for mounting and locking a screw rod, the magnetic shoe is plugged inside each square groove, two ends of the rotor are respectively provided with a sealed end cover, and each sealed end cover is locked and fixed through a locking screw rod. The magnetic-shoe built-in permanent-magnetic motor rotor is formed by press mounting a plurality of rotor punching sheets with the square slotted holes and the screw rod holes, and the magnetic shoe is plugged inside the rotor, so the magnetic shoe can be prevented from dropping during the work of a motor; and an antirust layer is coated outside the rotor, so the rusty phenomenon of the rotor can be avoided. The magnetic-shoe built-in permanent-magnetic motor rotor is convenient to manufacture, and the precision and the safety performance are greatly improved.
Description
Technical field
The utility model relates to the rotor of magneto, particularly a kind of magnetic shoe interior permanent magnet machines rotor.
Background technology
The magnetic shoe of permanent magnet machine rotor generally adopts external labeling type at present, promptly through adhesive magnetic shoe is sticked on the rotor external cylindrical surface, perhaps through panel magnetic shoe is fastened again.There is following shortcoming in a this porcelain watt external labeling type rotor rotor: 1. external cylindrical surface is beated and can't be guaranteed; 2, after motor worked long hours, the adhesive of pasting magnetic shoe was aging, even trip bolt is loosening, and magnetic shoe is prone to come off; 3, magnetic shoe dew is put at rotor outer surface easy-to-rust.
Summary of the invention
The purpose of the utility model provides a kind of raising rotor precision of beating, and guarantees that magnetic shoe does not come off because of the long-play of motor, thereby improves the magnetic shoe interior permanent magnet machines rotor of the security performance of motor.
Said a kind of magnetic shoe interior permanent magnet machines rotor comprises rotating shaft and rotor; It is characterized in that: said rotor is press-fited by a plurality of rotor punchings that have square slotted eye and screw and forms; The corresponding respectively groove and the screw hole that tie down screw is installed that is formed for inserting magnetic shoe that be communicated with of the square slotted eye of each rotor punching and screw; In each groove, inserted magnetic shoe, be provided with end cover at the two ends of rotor, end cover is locked through tie down screw.
Each rotor punching is provided with a plurality of square slotted eyes and screw, circularizes distribution respectively.
Said slotted eye is a rectangle, and a plurality of slotted eyes surround annular.
Outside at rotor is provided with antirust coat.
The utility model adopts a plurality of slotted eyes and screw rotor punching to press-fit and forms; Porcelain watt is inserted the inside at rotor; Can prevent that porcelain from watt coming off, and at the antirust coat that is externally coated with of rotor, can avoid rotor the phenomenon of corrosion to occur in machine operation; It is easily manufactured, and precision and security performance also improve greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the vertical view of the utility model,
Fig. 3 is the structural representation of rotor punching.
Among the figure: 1-rotating shaft, 2-rotor punching, 2-1-slotted eye, 2-2-screw, 3-porcelain watt, 4-tie down screw, 5-end cover, 6-rotor.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further; Among Fig. 1; Said a kind of magnetic shoe interior permanent magnet machines rotor comprises rotating shaft 1 and rotor 6, it is characterized in that: said rotor 6 is press-fited by a plurality of rotor punchings 2 that have slotted eye 2-1 and screw 2-2 and forms; The corresponding respectively groove and the screw hole that tie down screw 4 is installed that is formed for inserting magnetic shoe 3 that be communicated with of the slotted eye 2-1 of each rotor punching 2 and screw 2-2; In each groove, inserted magnetic shoe 3, be provided with end cover 5 at the two ends of rotor 6, end cover 5 is locked through tie down screw 4.
Each rotor punching 2 is provided with a plurality of slotted eye 2-1 and screw 2-2, circularizes distribution respectively.
Said slotted eye 2-1 is square, and a plurality of slotted eye 2-1 surround annular.
Outside at rotor 6 is provided with antirust coat.
The manufacturing process of the utility model: a plurality of rotor punchings 2 are press fit in the rotating shaft 1; The slotted eye 2-1 of its each rotor punching 2 and screw 2-2 are corresponding one by one respectively; Then tie down screw 4 is inserted among the screw 2-2, a plurality of rotor punchings 2 are fixedly locked, but can not lock too tight; Afterwards porcelain watts 3 is inserted in the groove that a plurality of slotted eye 2-1 form successively; A plurality of slotted eyes on each rotor punching 2 surround annular successively, and the porcelain of insertion watts 3 just forms a cylindrical shape, is wrapped in the inside of rotor 6; Then two ends end cap 5 is installed, and through tie down screw 4 lockings; Rotor outer surface finish turning with installing reaches dimensional requirement, eliminates cylindrical simultaneously and beats, and prepare the dynamic balancing piece, externally coats antirust coat then.
