Abstract
The utility model discloses a kind of novel vibration motor rotor, it includes metal iron core and longitudinally through the rotating shaft being arranged on the metal iron core, the metal iron core is circumferentially provided with three metal-toothed blocks by spacing distance, depression is provided with the first metal-toothed block outer peripheral face, the weight of the first metal-toothed block is less than the second metal-toothed block, the weight of the 3rd metal-toothed block.The utility model removes portion of material by the outer peripheral face of the metal-toothed block on metal iron core, and the quality of whole metal iron core is uneven, makes rotor uneven during rotation, so as to drive motor oscillating；To than conventional micromachine, more preferably, motor quality is guaranteed vibrating effect of the present utility model, and noise is small, and service life is longer.
Description
Technical field
Motor manufacture technology field is the utility model is related to, more particularly to a kind of novel vibration motor rotor.
Background technology
Current many micro-burst motors, all it is that eccentric wheel is riveted by output shaft end, so that rotor dynamic balancing amount changes
Become, after powered up, rotor banding movable eccentric wheel rotates motor, motor is integrally beated, so as to obtain vibrating function.In daily life
In, many daily necessitiess use the micro-burst motor of this type, and because eccentric wheel is to be riveted on during use
Output shaft end, caused vibration easily releases eccentric wheel to motor in use in itself, causes product vibrating effect to reduce or go out
The problems such as existing interference noise, motor quality decline, service life are short.
The content of the invention
The purpose of this utility model is, in view of the above-mentioned problems, providing a kind of novel vibration motor rotor.
Used technical scheme is the utility model to achieve the above object：
A kind of novel vibration motor rotor, it includes metal iron core and turned longitudinally through being arranged on the metal iron core
Axle, the metal iron core are circumferentially provided with three metal-toothed blocks by spacing distance, are set on the first metal-toothed block outer peripheral face
There is depression, the weight of the first metal-toothed block is less than the second metal-toothed block, the weight of the 3rd metal-toothed block.
The second metal-toothed block, the outer peripheral face of the 3rd metal-toothed block are circular arc camber.
The upper and lower both sides of the metal iron core are provided with insulating trip and lower insulating trip in structure identical, insulating trip on this,
Lower insulating trip is set in the rotating shaft.
It also includes piezo-resistance, commutator and the oil baffle set gradually, and the piezo-resistance, commutator and oil baffle are equal
It is set in the rotating shaft, the piezo-resistance, commutator and oil baffle are above the upper insulating trip.
The metal iron core is silicon steel component.
The beneficial effects of the utility model：The utility model is simple and reasonable, ingenious in design, by metal iron core
Metal-toothed block outer peripheral face remove portion of material, the quality of whole metal iron core is uneven, makes rotor during rotation
Imbalance, so as to drive motor oscillating；To than conventional micromachine, vibrating effect of the present utility model more preferably, motor quality
It is guaranteed, and noise is small, and service life is longer.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is the structural representation of metal iron core in the utility model；
Fig. 2 is the front view of metal iron core in the utility model；
Fig. 3 is structural representation of the present utility model.
Embodiment
Embodiment：As shown in Figure 1 to Figure 3, the utility model is a kind of novel vibration motor rotor, and it includes metal iron core
1 by spacing distance longitudinally through the rotating shaft 2 being arranged on the metal iron core 1, the metal iron core 1 with being circumferentially provided with three
Metal-toothed block, depression 4 is provided with the outer peripheral face of the first metal-toothed block 3, the weight of the first metal-toothed block 3 is less than second gold medal
Belong to tooth block 5, the weight of the 3rd metal-toothed block 6.
The second metal-toothed block 5, the outer peripheral face of the 3rd metal-toothed block 6 are circular arc camber.
The upper and lower both sides of the metal iron core 1 are provided with insulating trip 7 and lower insulating trip 8, insulation on this in structure identical
Piece 7, lower insulating trip 8 are set in the rotating shaft 2.
It also includes the piezo-resistance 9, commutator 10 and the oil baffle 11 that set gradually, the piezo-resistance 9, commutator 10 and
Oil baffle 11 is set in the rotating shaft 2, and the piezo-resistance 9, commutator 10 and oil baffle 11 are located on the upper insulating trip
Side,
The metal iron core 1 is silicon steel component.
By remove portion of material metal iron core 1 be set in rotating shaft 2, and set gradually piezo-resistance 9, commutator 10 and
Oil baffle 11.
The utility model is simple and reasonable, ingenious in design, is gone by the outer peripheral face of the metal-toothed block on metal iron core 1
Except portion of material, the quality of whole metal iron core 1 is uneven, makes rotor uneven during rotation, so as to drive motor
Vibration；To than conventional micromachine, vibrating effect of the present utility model more preferably, motor quality be guaranteed, and noise is small,
Service life is longer.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation.Any those skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore every content without departing from technical solutions of the utility model, the shape according to the utility model
The equivalence changes that shape, construction and principle are made, it all should be covered by the scope of protection of the utility model.
