Abstract

The utility model discloses a dustproof structure of an oil seal and a bearing of a motor. The dustproof structure of the oil seal and the bearing of the motor comprises a motor end cover, an elastic dustproof pad and a dustproof cover, an annular groove is arranged at the end part of the end cover, the inner peripheral surface of the dustproof cover is equipped with a convex ring matching the annular groove, and the elastic dustproof pad is arranged between the end cover and the dustproof cover. The advantages of the utility model are that: the dustproof structure of the oil seal and the bearing of the motor is simple in structure; the convex ring on the dustproof cover can match the annular groove on the end cover tightly, so that some sharp-pointed particles, such as silts, etc., can be effectively prevented from being contacted with the oil seal directly to there by cause wear, and accordingly, the service life of the motor can be improved substantially, and faults can be reduced.

Description

The dustproof construction of electric engine oil seal and bearing

Technical field

The utility model belongs to the electric vehicle motor technical field, especially relates to the dustproof construction of a kind of electric engine oil seal and bearing.

Background technology

Motor is the main parts size on the motor vehicle; it is the source of motor vehicle power; but existing motor vehicle for the protective device of motor seldom even do not have; when the silt of motor vehicle on the time channel face that travels under some rainwater weather easily proceeds to its inside; oil sealing and bearing are caused direct wearing and tearing; thereby affect the normal operation of motor, therefore be necessary to be improved.

Summary of the invention

The purpose of this utility model is the deficiency that exists for above-mentioned prior art, provides a kind of simple in structure, can effectively reduce outer boundry particle to the wearing and tearing of oil sealing, improves the anti-wear structure of the motor in motor useful life.

To achieve these goals, the technical scheme that the utility model adopts is: the dustproof construction of a kind of electric engine oil seal and bearing, comprise electric motor end cap, elasticity dust-proof cushion and dust cap, the end of described end cap is provided with annular groove, and the inner peripheral surface of dust cap is provided with the bulge loop that matches with annular groove; Described elasticity dust-proof cushion is arranged between end cap and the dust cap.

After adopting said structure, the utility model is compared with existing technology the advantage that has: of the present utility model simple in structure, bulge loop on the dust cap can with end cap on annular groove closely cooperate, so just can stop effectively that some sharp-pointed particles such as silt directly contact with oil sealing and cause its wearing and tearing, greatly improve the useful life of motor, and reduce the generation of fault.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified, the following stated only is preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.

Embodiment, see illustrated in figures 1 and 2: the dustproof construction of a kind of electric engine oil seal and bearing comprises electric motor end cap 10, elasticity dust-proof cushion 20 and dust cap 30; The end of described end cap 10 is provided with annular groove 11, the inner peripheral surface of dust cap 30 is provided with the bulge loop 31 that matches with annular groove 11, when annular groove 11 can be connected on the end cap 10 with dust cap 30 after bulge loop 31 cooperates, and elasticity dust-proof cushion 20 is between end cap 10 and dust cap 30, dust cap 30 and elasticity dust-proof cushion 20 just can some sharp-pointed particle gears externally, prevent that it from entering motor internal and oil sealing and bearing are caused wearing and tearing like this.

Claims
