Abstract
The utility model discloses a motor which comprises an end cover group, stators and rotors, wherein the stators and the rotors are arranged in the end cover group. Ball bearings are arranged on the end cover group. A rotation shaft of the rotors penetrates the ball bearings. Both ends of each rotor are sequentially sheathed with telescopic springs, gaskets and oil bearing felts. One end of each telescopic spring abuts against the end face of a rotor, and the other end of each telescopic spring supports a gasket. Each oil bearing felt is close to a ball bearing. Compared with the prior art, one end of each telescopic spring abuts against the end face of a rotor, and the other end supports a gasket; and each oil bearing felt is close to a ball bearing. When the rotors rotate, the rotors extrude the telescopic springs. The telescopic springs impose force on the oil bearing felts to extrude lubricating oil. When the telescopic springs support the rotors to home positions by using own characteristics, the oil bearing felts automatically suck released lubricating oil because no force is on the oil bearing felts. Repeatedly, the purpose of automatic lubrication is realized. The motor provided by the utility model has the advantages of stable operation and long service life.
Description
Technical field
The utility model relates to a kind of motor.
Background technology
Motor is when operation, because load is heavy, machine shaft produces axial motion, rotor contacts with the bearing collision, the noise and the strike note that produce are larger, for this situation, in the prior art, by the two ends at rotor rubber axle sleeve and pad are set, the problem of rotor and bearing axial impact has effectively been alleviated in the use of rubber axle sleeve, has reduced noise, yet rotating shaft in rotation with eccentric load, machine shaft and bearing have friction, need to consume more lubricating oil, and motor is in the situation that internal lubrication is inadequate motor is blocked do not turn, interpolation lubricating oil then needs to such an extent that open electric motor end cap or injects from oilhole, and is very inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of motor for above-mentioned the deficiencies in the prior art, can realize motor self-lubricate, improves the motor runnability and increases the service life.
For achieving the above object, the technical solution of the utility model is: a kind of motor, comprise the end cap group, and be installed in end cap group interior stator and rotor, and being provided with ball bearing on the described end cap group, the rotating shaft of rotor passes from described ball bearing, the two ends of rotor all are set with successively from inside to outside coil tension spring, pad and contain asphalt felt, one end of coil tension spring is near rotor end-face, and the other end of coil tension spring supports described pad, contains asphalt felt and is close to ball bearing.
As the further setting of such scheme, the described material that contains asphalt felt is string, contains the race diameter of asphalt felt less than the inner ring diameter of ball bearing.
The beneficial effects of the utility model are: compared with prior art, one end of coil tension spring is near rotor end-face, other end supporting contains asphalt felt and is close to ball bearing, when the rotor vibration, rotor extruding coil tension spring, coil tension spring then contains the asphalt felt active force, extrude lubricating oil, when coil tension spring utilizes himself characteristic with rotor bearing during to original position, contain asphalt felt and be not subject to the then automatic intussusception lubricating oil of emitting of active force, so repeatedly, reached self-lubricated purpose, so that the utility model operation is more steady, useful life is more permanent.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, end cap group, 2, stator, 3, rotor, 4, ball bearing, 5, rotating shaft, 6, coil tension spring, 7, pad, 8, contain asphalt felt.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, the utility model comprises end cap group 1, and be installed in stator 2 and rotor 3 in the end cap group 1, be provided with ball bearing 4 on the described end cap group 1, the rotating shaft 5 of rotor 3 passes from described ball bearing 4, and the two ends of rotor 3 all are set with successively from inside to outside coil tension spring 6, pad 7 and contain asphalt felt 8, and an end of coil tension spring 6 is near rotor 3 end faces, the other end of coil tension spring 6 supports described pad 7, contains asphalt felt 8 and is close to ball bearing 4.
The described material that contains asphalt felt 8 is string, contains the race diameter of asphalt felt 8 less than the inner ring diameter of ball bearing 4.
Operation principle of the present utility model is: the two ends of rotor 3 all are set with coil tension spring 6 from inside to outside successively, pad 7 and contain asphalt felt 8, one end of coil tension spring 6 is near rotor 3 end faces, other end bearing pad 7 makes and contains asphalt felt 8 and be close to ball bearing 4, contain the race diameter of asphalt felt 8 less than the inner ring diameter of ball bearing 4, so that ball bearing 4 in, the outer ring can normal rotation, when rotor 3 produces vibration, rotor 3 extruding coil tension springs 6,6 of coil tension springs contain 8 one active forces of asphalt felt by pad 7, contain asphalt felt 8 and extrude lubricating oil, when coil tension spring 6 utilizes himself characteristic that rotor 3 supportings are returned to original position, contain asphalt felt 8 and be not subject to active force, the automatic intussusception lubricating oil of emitting then, so repeatedly, reached self-lubricated purpose, so that the utility model operation is more steady, useful life is more permanent.
