Abstract

The utility model discloses a vibration motor comprising a motor, an eccentric wheel 6, and a spring 4; wherein the eccentric wheel 6 is arranged on a motor shaft 1 of the motor, the spring 4 is sleeved on the motor shaft 1 between the eccentric wheel 6 and the motor; gaskets are provided between the spring 4 and an end face of the eccentric wheel 6 and between the spring 4 and an inner ring of a motor bearing 2; and one end of the spring 4 is arranged against the end face of the eccentric wheel 6 through the gasket 5, the other end of the spring 4 is arranged against the inner ring of the motor bearing 2 through the gasket 3. When the motor works, the spring 4 can effectively absorb an axial force generated by the eccentric wheel 6 on the motor shaft 1, thereby greatly reducing an impact force of a play, enabling the eccentric wheel 6 and the bearing in the motor to work stably, and effectively reducing abnormal noises, therefore, the bearing is not easy to wear, and a service life of the bearing can be prolonged.

Description

A kind of vibrating motor

Technical field

The utility model relates to a kind of vibrating motor, belongs to the motor technology field.

Background technology

On the motor shaft of vibrating motor eccentric wheel is installed; Motor shaft drives eccentric wheel and rotates, and eccentric inertia force produces needed vibrations, simultaneously; Eccentric inertia force also produces extra axial force on motor shaft; Make motor shaft back and forth constantly play axially take place, cause bearing easy abrasion, life-span low, bring extraordinary noise simultaneously.

The utility model content

The purpose of the utility model just is to provide a kind of vibrating motor, it can effectively protect bearing not frayed, increase the service life, effectively reduce extraordinary noise.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of vibrating motor; Comprise motor, eccentric wheel, spring; Eccentric wheel is installed on the motor shaft of motor, is with spring on the motor shaft between eccentric wheel and the motor, and spring one end is against the inner ring that eccentric end face, the other end are against motor bearings.For protecting the inner ring of eccentric end face and motor bearings, guarantee the long-term operate as normal of spring simultaneously, between spring and the eccentric end face, also be provided with packing ring between the inner ring of spring and motor bearings.

Adopt such structure; Though having, the axial force that eccentric wheel produces on motor shaft make motor shaft back and forth constantly in the trend that play axially takes place; But spring can absorb its kinetic energy effectively, greatly reduces the trend of play, makes eccentric wheel and motor inner bearing stable working; That bearing is difficult for is frayed, be able to prolong useful life, has effectively reduced extraordinary noise simultaneously.

Description of drawings

Fig. 1 is the structural principle sketch map of a kind of vibrating motor of the utility model.

Fig. 2 is the structural representation of a kind of vibrating motor embodiment of the utility model.

In the accompanying drawing:

1 motor shaft; 2 motor bearingss; 3 packing rings;

4 springs; 5 packing rings; 6 eccentric wheels.

Embodiment

Fig. 1 to Fig. 2 has provided the embodiment of a kind of vibrating motor of the utility model; A kind of vibrating motor of the utility model comprises motor, eccentric wheel 6, spring 4; Eccentric wheel 6 is installed on the motor shaft 1 of motor; Be with spring 4 on the motor shaft 1 between eccentric wheel 6 and the motor; Be provided with between the end face of spring 4 and eccentric wheel 6 between the inner ring of packing ring 5, spring 4 and motor bearings 2 and be provided with packing ring 3, an end of spring 4 is against the end face of eccentric wheel 6, the other end is against motor bearings 2 through packing ring 3 inner ring through packing ring 5.

During machine operation; Motor shaft 1 drives eccentric wheel 6 rotations; The axial force that eccentric wheel 6 produces on motor shaft 1 is absorbed the elastic potential energy that changes spring 4 into effectively by spring 4 and slowly discharges, and greatly reduces the impulsive force of play, makes eccentric wheel 6 and motor inner bearing stable working; Effectively reduced extraordinary noise, that bearing is difficult for is frayed, be able to prolong useful life.

If spring 4 directly contacts with the end face of eccentric wheel 6, the inner ring of motor bearings 2; The end face of easy scratch eccentric wheel 6, the inner ring of motor bearings 2; Therefore between the inner ring of the end face of spring 4 and eccentric wheel 6, motor bearings 2, be provided with packing ring, the while also guarantees spring 4 long-term operate as normal.

The above is merely the preferred embodiment of the utility model; It is not qualification to the utility model protection range; The those skilled in the art is in the spirit and scope of the utility model that does not break away from claims and limited; In form with details on many variations that the utility model is made, all fall into the protection range of the utility model.
