Abstract
A sealing element of a motor is an integrated element consisting of a seal lip and a connection part, wherein the connection part is provided with an annular boss; an annular concave groove is formed on the inner side of the seal lip; and an annular elastic steel piece is clamped in the annular concave groove. In the utility model, the annular elastic steel piece is clamped in the concave groove on the inner side of the seal lip. When the motor is used, with the seal lip being abraded continuously, the elasticity of the annular elastic steel piece can apply an inward pressure for the seal lip, so that the seal lip is always in close contact with an output shaft of the motor for sealing, water is prevented from entering into the motor and damaging the motor through the output shaft of the motor, and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of seal, relates in particular to a kind of seal of motor.
Background technology
The waterproof sealing of motor is extremely important, and the water that enters motor internal can burn out motor, thereby reduces the useful life of motor.Seal on the motor is a circular steel part at present, because motor in use steel part constantly is worn, cause forming certain clearance between seal and the axle, make outside water enter motor internal and damage motor, the useful life of having reduced motor by axle.
The utility model content
The technical problems to be solved in the utility model provides a kind of seal of motor of good airproof performance.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of seal of motor, it is the integral piece that is made of sealing lip and coupling part, and described coupling part is provided with annular boss, and described sealing lip inboard is provided with annular groove, and card has the cyclic spring steel disc in the described annular groove.
The seal of the utility model motor, the vertical section of wherein said annular groove are V-arrangement or U-shaped, and correspondingly, the vertical section of described cyclic spring steel disc is V-arrangement or U-shaped.
The seal of the utility model motor, wherein said vertical section are that the angle α of the annular groove of V-arrangement can be made as 30-60 degree.Angle α preferably is made as 45 degree.
The seal of the utility model motor, wherein said sealing lip slopes inwardly along circumference, and it is 15-45 degree with respect to axial angle of inclination beta.Angle of inclination beta preferably is made as 22.5 degree.
The seal of the utility model motor, wherein said sealing lip, coupling part are made by waterproof material.
The seal of the utility model motor blocks in the groove of sealing lip inboard the cyclic spring steel disc, in the motor use, along with sealing lip constantly is worn, the elastic force of cyclic spring steel disc can be given the inside pressure of sealing lip, make sealing lip tightly contact and seal with motor output shaft all the time, anti-sealing enters motor internal by motor output shaft and damages motor, has prolonged the useful life of motor.
Description of drawings
Fig. 1 is that the seal of the utility model motor is installed in the structural representation on the motor;
Fig. 2 is an A place enlarged drawing among Fig. 1;
Fig. 3 is the cutaway view of the seal of the utility model motor.
Embodiment
As shown in Figure 3, the seal 6 of the utility model motor is the integral piece that is made of sealing lip 1 and coupling part 2, and coupling part 2 is provided with annular boss 3, and sealing lip 1 inboard is provided with annular groove 4, and card has cyclic spring steel disc 5 in the annular groove 4.The vertical section of annular groove 4 can be V-arrangement or U-shaped, and correspondingly, the vertical section of cyclic spring steel disc 5 is V-arrangement or U-shaped, is V-arrangement in the present embodiment.The vertical section is that the angle α of the annular groove 4 of V-arrangement can be made as 30-60 degree, and angle α preferably is made as 45 degree.Sealing lip 1 slopes inwardly along circumference, and it is 15-45 degree with respect to axial angle of inclination beta, and angle of inclination beta preferably is made as 22.5 degree.Sealing lip 1, coupling part 2 are made by waterproof material such as polyvinyl chloride, polyurethane.
Fig. 1, the seal 6 that Figure 2 shows that the utility model motor are installed in the structural representation on the motor 11.Bearing (ball) cover 9 is housed on the electric motor end cap 8, bearing (ball) cover 9 be provided with seal 6 on the groove that is complementary of annular boss 3, so that seal 6 is fixed on the bearing (ball) cover 9, between bearing (ball) cover 9 and seal 6, sealing ring 10 is housed also.Sealing lip 1 and motor output shaft 7 slipper seals.Motor 11 in use, along with the sealing lip 1 of seal 6 constantly is worn, the elastic force of cyclic spring steel disc 5 can give sealing lip 1 inside pressure, make sealing lip 1 tightly contact and seal with motor output shaft 7 all the time, anti-sealing enters motor 11 internal damage motors 11 by motor output shaft 7, has prolonged the useful life of motor 11.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection range of the utility model claims.
