Abstract
The utility model belongs to the technical field of motor appliances and particularly relates to a commutator. The utility model discloses a commutator. The commutator comprises a cylinder provided with a shaft hole at the center and a mica layer on the side part. A plurality of conductive medium strips are evenly distributed on the outer side of the mica layer. The conductive medium strips are parallelly arranged along the axial direction of the cylinder, and insulating medium layers are arranged between the adjacent conductive medium strips. Commutator segments are arranged at one ends of the conductive medium strips and extend out of the cylinder in V shapes. The commutator is reasonable in structure, and strength and functions of the entire commutator are further reinforced, so that the service life of the commutator is extended.
Description
Technical field
The utility model belongs to motor apparatus technical field, relates in particular to a kind of commutator.
Background technology
Commutator is the vitals of direct current machine, and effect is that the direct current being passed through on brush is converted to the alternating current in winding or the alternating electromotive force in winding is converted to the direct electromotive force. on brush end.Principle is, when coil is by after electric current, can be under the effect of permanent magnet, by attraction and repulsive force, rotate, when it forwards to magnet balance, the contact originally leading on the more corresponding commutator of line of electricity is just separated with brush, and brush is connected to and meets that produce motive force and organize on the contact that coil is corresponding, so ceaselessly repeat down, DC motor has just been turned over.The commutator existing at present exists unreasonable structure, is easy to make commutator wear, thereby has shortened its service time.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of commutator is provided, and its technical scheme is as follows:
A kind of commutator, comprise cylinder, it is characterized in that, described cylindrical center is provided with axis hole, and described cylindrical sidepiece is provided with mica layer, and the outside of described mica layer is evenly distributed with some conducting medium bars, described conducting medium bar be arranged in parallel in cylindrical axially on, between described conducting medium bar is adjacent, be provided with insulating medium layer, the place, one end of described conducting medium bar is provided with commutator segment, and described commutator segment is inverted V-shaped to cylindrical outside extension.
Optimal way is, in described axis hole, is provided with reinforcing ring, and described reinforcing ring is positioned at the place, two ends of axis hole.
The commutator that the utility model provides, when in use, described cylindrical sidepiece is provided with mica layer, by mica sheet, can be played preferably certain insulating effect and be alleviated the weight of whole steering gear.Can be so that whole steering gear can better reach optimum effect when in use.The outside of described mica layer is evenly distributed with some conducting medium bars, described conducting medium bar be arranged in parallel in cylindrical axially on.By conducting medium bar, can well play the effect of conduction, make steering gear can function reach optimization.Between described conducting medium bar is adjacent, be provided with insulating medium layer, make to play between each commutator segment the effect of insulation.The place, one end of described conducting medium bar is provided with commutator segment, and described commutator segment is inverted V-shaped to cylindrical outside extension.By commutator segment, can, so that whole commutator and motor combine, play the effect of commutator in motor.
In axis hole described in the utility model, be provided with reinforcing ring, described reinforcing ring is positioned at the place, two ends of axis hole.By reinforcing ring, can the intensity of whole commutator be got a promotion so that the function of whole commutator is further promoted, be conducive to increase its service time.
Structure rationalization of the present utility model, is further strengthened the intensity of whole steering gear and function, extends its service time.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
A kind of commutator, comprise cylinder 1, it is characterized in that, the center of described cylinder 1 is provided with axis hole 2, the sidepiece of described cylinder 1 is provided with mica layer 3, the outside of described mica layer 3 is evenly distributed with some conducting medium bars 4, described conducting medium bar 4 be arranged in parallel in cylinder 1 axially on, between described conducting medium bar 4 is adjacent, be provided with insulating medium layer, the place, one end of described conducting medium bar 4 is provided with commutator segment 5, and described commutator segment 5 is inverted V-shaped and extends to the outside of cylinder 1.
Optimal way is, in described axis hole 2, is provided with reinforcing ring 6, and described reinforcing ring 6 is positioned at the place, two ends of axis hole 2.
The commutator that the utility model provides, when in use, described cylindrical sidepiece is provided with mica layer, by mica sheet, can be played preferably certain insulating effect and be alleviated the weight of whole steering gear.Can be so that whole steering gear can better reach optimum effect when in use.The outside of described mica layer is evenly distributed with some conducting medium bars, described conducting medium bar be arranged in parallel in cylindrical axially on.By conducting medium bar, can well play the effect of conduction, make steering gear can function reach optimization.Between described conducting medium bar is adjacent, be provided with insulating medium layer, make to play between each commutator segment the effect of insulation.The place, one end of described conducting medium bar is provided with commutator segment, and described commutator segment is inverted V-shaped to cylindrical outside extension.By commutator segment, can, so that whole commutator and motor combine, play the effect of commutator in motor.
