Abstract
The utility model discloses a shockproof rotor which comprises rotation shafts, a rotor body and permanent magnets. The rotation shaft is fixedly connected with the rotor body; the rotor body is provided with a plurality of permanent magnet holding grooves. The rotation shafts at two sides of the rotor body are provided with fixed discs. The fixed discs are provided with a plurality of clamp grooves for having the permanent magnets fixed. The permanent magnets are in a strip shape and are provided with two fixing parts extending outwardly. The long strip parts are embedded to the rotor body holding groove. The fixing parts are arranged in the clamp grooves of the fixed discs. The rotor body is hollow in the middle part and the middle part is filled with soft materials. The rotor body and the rotation shafts are fixedly connected through key grooves; the key grooves are provided with a plurality of surrounding rotation shafts on the circumferences in a uniform manner. The shockproof rotor of the utility model overcomes the shortcomings in prior art. Designed with a compact structure, the permanent magnets are fixed in a fastened manner and do not deviate easily. The service lifetime is also prolonged. The soft materials filled inside the rotor body and the fixed connection of the rotation shafts with the key grooves all help reduce the inertia impacts.
Description
Technical field
The utility model relates to motor component technical field, specifically belongs to a kind of Shockproof rotor.
Background technology
Motor is the conversion equipment for realizing electric energy and mechanical energy and mechanical energy and electric energy, and rotor is the rotating parts in motor, belongs to easy wearing detail.Existing rotor is in running, and permanent magnet is easily shifted or departs from rotor block, has shortened the useful life of rotating, and motor is difficult to work long hours simultaneously, reduces the durability of motor.Although the patent that existing special issue is CN203278437U has adopted some technological means to reinforce permanent magnet fixing in rotor block, but be all some conventional reinforcing modes that adopt, and be mostly to adopt some connectors to reinforce the connection, cause like this, install loaded down with trivial details, easily long easily appearance becomes flexible, and overall Use Limitation fruit is undesirable.Not deflate of such vibration while also having rotor to rotate under some specific rotating speed, can there is very large distortion and cause resonance, if will affect the fastness that permanent magnet is installed.
Utility model content
The purpose of this utility model has been to provide a kind of Shockproof rotor, has overcome the deficiencies in the prior art, project organization compactness, and permanent magnet fixation, is not prone to skew, long service life; The keyway passing through between its interior flexible material of rotor block and rotor block and rotating shaft is fixedly connected with, and reduces its inertia impulsive force.
The technical solution adopted in the utility model is as follows:
A kind of Shockproof rotor, comprise rotating shaft, rotor block and permanent magnet, described rotating shaft is fixedly connected with rotor block, rotor block is provided with multiple permanent magnet standing grooves, the rotating shaft of rotor block two side positions is provided with fixed disk, fixed disk is provided with multiple permanent magnet fixed card slots, described permanent magnet is strip, two have outward extending standing part, microscler being partly embedded in rotor block standing groove, standing part is arranged in fixed disk draw-in groove, described rotor block inside middle hollow, hollow space is filled with flexible material, between rotor block and rotating shaft, be connected and fixed by keyway, keyway is provided with and is multiplely uniformly distributed around shaft circumference.
Described rotating shaft two ends are all fixed with radiator fan.
On described rotor block both ends, be equipped with retainer ring.
Described flexible material is foam, flexible plastics.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The fixation of the utility model permanent magnet, is not prone to skew, long service life; The keyway passing through between its interior flexible material of rotor block and rotor block and rotating shaft is fixedly connected with, and reduces its inertia impulsive force.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of Shockproof rotor, comprise rotating shaft 1, rotor block 2 and permanent magnet 3, rotating shaft 1 is fixedly connected with rotor block 2, rotor block 2 is provided with multiple permanent magnet standing grooves 201, the rotating shaft of 2 liang of side positions of rotor block is provided with fixed disk 3, fixed disk is provided with multiple permanent magnet fixed card slots 301, described permanent magnet 3 is strip, two have outward extending standing part, microscler being partly embedded in rotor block standing groove, standing part is arranged in fixed disk draw-in groove, planform is just equivalent to and permanent magnet and rotor block is fixedly secured in one like this, permanent magnet is carried out to horizontal and vertical location, described rotor block 2 inside middle hollows, hollow space is filled with foam 202, between rotor block and rotating shaft, be connected and fixed by keyway 101, keyway is provided with and is multiplely uniformly distributed around shaft circumference.On rotor block both ends, be equipped with retainer ring 203, further reinforced permanent magnet and be fixed on rotor block, project organization compactness, described rotating shaft two ends are all fixed with radiator fan 4, improve its radiating effect.
