Abstract
The invention belongs to the technical field of motor appliances, and particularly relates to a commutator. The commutator comprises a cylinder, a shaft hole is formed in the center of the cylinder, a mica layer is arranged on the side portion of the cylinder, a plurality of conducting medium strips are evenly distributed on the outer side of the mica layer, the conducting medium strips are arranged in the axial direction of the cylinder in parallel, insulation medium layers are arranged between adjacent conducting medium layers, a commutator bar is arranged at one end of each conducting medium strip, and the commutator bars extend to the outer portion of the cylinder in an inverted V shape. The commutator is reasonable in structure, the strength and the function of the entire commutator are made to be further enhanced, and the service life of the commutator is prolonged.
Description
Technical field
The invention belongs to motor apparatus technical field, relate in particular to a kind of commutator.
Background technology
Commutator is the vitals of direct current machine, and effect is that the direct current will 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 the brush end.Principle is, after coil passes through electric current, can be under the effect of permanent magnet, by attracting and the repulsive force rotation, when it forwards to the magnet balance, the contact originally led 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 existed at present exists unreasonable structure, is easy to make commutator wear, thereby has shortened its service time.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of commutator is provided, 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, be provided with insulating medium layer between described conducting medium bar is adjacent, an end place of described conducting medium bar is provided with commutator segment, and described commutator segment is inverted V-shaped to cylindrical outside the 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.
Commutator provided by the invention, when in use, described cylindrical sidepiece is provided with mica layer, by mica sheet, can play preferably certain insulating effect and alleviate 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.Can well play the effect of conduction by the conducting medium bar, make steering gear can function reach optimization.Be provided with insulating medium layer between described conducting medium bar is adjacent, make the effect of playing insulation between each commutator segment.One end place of described conducting medium bar is provided with commutator segment, and described commutator segment is inverted V-shaped to cylindrical outside the extension.Can, so that whole commutator and motor combine, play the effect of commutator in motor by commutator segment.
Be provided with reinforcing ring in axis hole of the present invention, described reinforcing ring is positioned at the place, two ends of axis hole.By reinforcing ring, can make the intensity of whole commutator get a promotion so that the function of whole commutator is further promoted, be conducive to increase its service time.
Structure rationalization of the present invention, make the intensity of whole steering gear and function further be strengthened, and extends its service time.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
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, be provided with insulating medium layer between described conducting medium bar 4 is adjacent, one end place 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.
Commutator provided by the invention, when in use, described cylindrical sidepiece is provided with mica layer, by mica sheet, can play preferably certain insulating effect and alleviate 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.Can well play the effect of conduction by the conducting medium bar, make steering gear can function reach optimization.Be provided with insulating medium layer between described conducting medium bar is adjacent, make the effect of playing insulation between each commutator segment.One end place of described conducting medium bar is provided with commutator segment, and described commutator segment is inverted V-shaped to cylindrical outside the extension.Can, so that whole commutator and motor combine, play the effect of commutator in motor by commutator segment.
