Abstract
The invention belongs to the technical field of motor production and particularly relates to a motor. The motor comprises a shell and an end cap. The shell is internally provided with a rotor and a rotary shaft. A commutator is arranged on one side of the rotor. Two ends of the rotary shaft rotationally support in the end cap through bearings. A wear washer set is arranged between each bearing and a step which is arranged at each of two ends of the rotary shaft. Elastic adjusting rings are clamped between the wear washer sets and made of rubber material. The motor is simple in structure and reasonable in design, allows the axial play of the rotor of the motor to be effectively adjusted to allow the play clearances being consistent and is low in vibration and noise, long in service life, convenient to use and suitable to promotion and application.
Description
Technical field
The invention belongs to motor manufacturing technology field, particularly relate to a kind of motor.
Background technology
Existing motor itself is owing to there being defect in structure, cause the axial endplay of rotor larger, make originally should not relative motion binding site gap become large, and then make vibrations, the noise of motor become large, even there is " sweeping thorax " possibility, the useful life of reducing motor.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of reasonable in design is provided, and can effectively regulate the axial motion of rotor, axial motion gap is consistent, and reduce vibrations, the noise of motor, improve the motor in useful life.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of motor, comprise shell and end cap, in shell, be provided with rotor and rotating shaft, and rotor one side is provided with commutator, rotating shaft two ends are rotatably supported in end cap inner side by bearing, between the set step in rotating shaft two ends and bearing, be separately installed with one group of wear washer, among every group of wear washer, clamp flexible adjusting ring, and this flexible adjustment circle adopts quality of rubber materials to make.
Described bearing is oily globule bearing.
Every group of wear washer has two or three.
The beneficial effect of technical solution of the present invention is:
1, structurally, the present invention is the position near wear washer at motor two ends, increases a flexible adjustment circle, utilizes its suitable elasticity, both can effectively regulate the axial motion of rotor, and axial motion gap is consistent; Can utilize again its elasticity and quality of rubber materials to effectively reduce vibration and the frictional noise of motor, improve the useful life of motor.
2, structurally, bearing of the present invention is oily globule bearing, have cost low, can absorbing, noise is little, within the longer operating time without features such as apply oils, be specially adapted to be difficult in motor housing lubricated or do not allow the dirty operational environment of oil, easy to use, be conducive to promotion and implementation.
3, to sum up, electric machine structure of the present invention is simple, reasonable in design, can effectively regulate the axial motion of rotor, axial motion gap is consistent, reduces vibrations, the noise of motor, improve motor useful life, and easy to use, therefore, be very suitable for promotion and implementation.

embodiment
Embodiment mono-:
Referring to Fig. 1, Fig. 2, in figure, motor of the present invention, comprise shell 1 and end cap 2, in shell, be provided with rotor 3 and rotating shaft 4, and rotor one side is provided with commutator 5, rotating shaft two ends are rotatably supported in end cap inner side by bearing, between the set step in rotating shaft two ends and bearing, be separately installed with one group of wear washer 6, among every group of wear washer, clamp flexible adjusting ring 7, and this flexible adjustment circle adopts quality of rubber materials to make.Described bearing is oily globule bearing 8.The one group of wear washer in motor left side has two, and one group, right side wear washer has three.
The present invention is the position near wear washer at motor two ends, increases a flexible adjustment circle, utilizes its suitable elasticity, both can effectively regulate the axial motion of rotor, and axial motion gap is consistent; Can utilize again its elasticity and quality of rubber materials 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 is little, within the longer operating time without features such as apply oils, be specially adapted to be difficult in motor housing lubricated or do not allow the dirty operational environment of oil, easy to use, be conducive to promotion and implementation.
The foregoing is only the schematic embodiment of the present invention; not in order to limit scope of the present invention; any those skilled in the art, not departing from equivalent variations and the modification of making under the prerequisite of design of the present invention and principle, all should belong to the scope of protection of the invention.
