Abstract

The utility model relates to a motor device, which comprises a motor, a bearing and a commutator. The bearing and the commutator are sleeved on a spindle of the motor, a shaft sleeve is disposed between the bearing and the commutator, and an annular oil baffle plate is arranged at one end, which is close to the commutator, of the shaft sleeve. The shaft sleeve with a special structure is mounted between the bearing and the commutator, accordingly, oil in the bearing is prevented from being splashed into the commutator, the service life of the motor is prolonged, maintenance cost of the motor is reduced, and the motor device is simple in structure and convenient in modification, and has better market prospect.

Description

A kind of electric machine

Technical field

The utility model relates to a kind of electric machine.

Background technology

Growing along with mechanical technique, motor is as a kind of drive unit, and application is seen everywhere.Machine does not have motor just not have heart as the people, can't work, so it is most important to protect motor.We know that rotor rotates, and can not import rotor coil to power supply with fixing line, so, the power supply electric energy is imported in the rotor coil through the carbon brush on the commutator and the sliding contact of slip ring.Because the commutator position of motor and the position of bearing are close, under high-temperature condition, the oil of bearing may fly into commutator under the effect of rotation, cause motor to lose efficacy, influenced the operation of a machine, and maintenance motor or change motor again and both lost time and sink money brings very big loss to the mankind.So how to avoid the oil in the bearing to fly into the emphasis that commutator is the field of bearings scientific research always.

Summary of the invention

At above-mentioned defective, the utility model provides a kind of electric machine, can effectively avoid the oil at motion middle (center) bearing place to fly into commutator, has improved the useful life of motor.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of electric machine, comprise motor, bearing, commutator, described bearing and commutator are enclosed within on the main shaft of motor, be provided with axle sleeve between described bearing and the commutator, described axle sleeve is provided with annular oil baffle near an end of commutator.

As further improvement of the utility model: described annular oil baffle is to the bent camber structure of bearing one lateral bending, further dwindle the gap between oil baffle and the end cap, reduce the probability that oil flies out, can make the oil that splashes when the bump curved baffle, one reaction force that glides be arranged again, can reduce baffle plate simultaneously and take up space.

The utility model is by installing the axle sleeve of special construction between bearing and commutator, avoid the oil in the bearing to fly into commutator, prolonged the life-span of motor, reduced the maintenance cost of motor, and the utility model is simple in structure, repacking is convenient, has market prospects preferably.

Description of drawings

Fig. 1 is the cutaway view of the utility model structure;

Fig. 2 is the front view of the utility model bottom bracket axle;

Fig. 3 is the A-A cutaway view of Fig. 2;

Among the figure: motor 1, main shaft 1-1, bearing 2, commutator 3, axle sleeve 4, oil baffle 4-1.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment, referring to accompanying drawing 1, the utility model relates to a kind of electric machine, comprises motor 1, bearing 2, commutator 3 and axle sleeve 4, bearing 2 and commutator 3 are socketed on the main shaft 1-1 of motor 1, and described axle sleeve 4 is socketed on the electric machine main shaft 1-1 and between bearing 2 and commutator 3.

As shown in Figures 2 and 3: a side of axle sleeve 4 also is provided with annular oil baffle 4-1, and described oil baffle 4-1 bends to arcuate structure to the other end direction of axle sleeve 4.

As shown in Figure 1: when the utility model was installed, an end that axle sleeve 4 is had oil baffle 4-1 was installed near commutator 3; When oil flew out from bearing 2, the cambered surface along with bearing 2 under action of centrifugal force flew out, and glided with running into arc oil baffle 4-1, thereby had avoided oil to fly into the normal operation that commutator 3 influences motor 1.

The utility model is simple in structure, repacking is convenient, can postpone the useful life of motor greatly, has reduced the maintenance cost of motor, has good actual use value.

Claims
