Description

A kind of motor

Technical field

The utility model belongs to technical field of motor manufacture, particularly relates to a kind of motor.

Background technology

Existing motor itself is due to existing defects in structure, the axial endplay causing rotor is comparatively large, makes originally the binding site gap of relative motion should not to become large, and then make the vibrations of motor, noise becomes large, even there is " sweeping thorax " possibility, reduce the useful life of motor.

Summary of the invention

The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of reasonable in design is provided, effectively can regulate the axial endplay of rotor, axial movement space is consistent, and reduce vibrations, the noise of motor, improve the motor in useful life.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A kind of motor, comprise shell and end cap, rotor and rotating shaft is provided with in shell, and rotor side is provided with commutator, rotating shaft two ends are rotatably supported in inside end cap by bearing, set by rotating shaft two ends, between step and bearing, be separately installed with one group of wear washer, clamp flexible adjusting ring often organizing among wear washer, and this flexible adjustment circle adopts quality of rubber materials to make.

Described bearing is oily globule bearing.

Often organize wear washer and have two or three.

The beneficial effect of technical solutions of the utility model is:

1, structurally, the utility model, at the position of motor two ends near wear washer, increases a flexible adjustment circle, utilizes the elasticity that it is suitable, both effectively can regulate the axial endplay of rotor, axial movement space is consistent; Its elasticity and quality of rubber materials can be utilized again to effectively reduce vibration and the frictional noise of motor, improve the useful life of motor.

2, structurally, bearing described in the utility model is oily globule bearing, have cost low, can absorbing, noise little, within the longer operating time without features such as apply oils, be specially adapted to the operational environment not easily lubricating in motor housing or do not allow oil dirty, easy to use, be conducive to promotion and implementation.

3, to sum up, the utility model electric machine structure is simple, reasonable in design, effectively can regulate the axial endplay of rotor, axial movement space is consistent, reduces the vibrations of motor, noise, improve motor useful life, and easy to use, therefore, be very suitable for promotion and implementation.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:

Fig. 1 is the structural representation of the utility model motor;

The side-looking structural representation that Fig. 2 is motor shown in Fig. 1;

The structure for amplifying schematic diagram of the local I that Fig. 3 is motor shown in Fig. 1;

Sequence number in figure: 1, shell, 2, end cap, 3, rotor, 4, rotating shaft, 5, commutator, 6, wear washer, 7, flexible adjustment circle, 8, oily globule bearing.

Embodiment

Embodiment one:

See Fig. 1-Fig. 3, in figure, the utility model motor, comprise shell 1 and end cap 2, be provided with rotor 3 and rotating shaft 4 in shell, and rotor side is provided with commutator 5, rotating shaft two ends are rotatably supported in inside end cap by bearing, set by rotating shaft two ends, between step and bearing, be separately installed with one group of wear washer 6, clamp flexible adjusting ring 7 often organizing among wear washer, and this flexible adjustment circle adopts quality of rubber materials to make.Described bearing is oily globule bearing 8.On the left of motor, one group of wear washer has two, and one group, right side wear washer has three.

The utility model, at the position of motor two ends near wear washer, increases a flexible adjustment circle, utilizes the elasticity that it is suitable, both effectively can regulate the axial endplay of rotor, axial movement space is consistent; Its elasticity and quality of rubber materials can be utilized again to effectively reduce vibration and the frictional noise of motor, improve the useful life of motor.In addition, described bearing is oily globule bearing, have cost low, can absorbing, noise little, within the longer operating time without features such as apply oils, the operational environment being specially adapted in motor housing not easily lubrication or not allowing oil dirty, easy to use, be conducive to promotion and implementation.

The foregoing is only the schematic embodiment of the utility model; and be not used to limit scope of the present utility model; the equivalent variations that any those skilled in the art makes under the prerequisite not departing from the utility model design and principle and amendment, all should belong to the scope of the utility model protection.
