Abstract
The utility model belongs to the technical field of motor appliances and particularly relates to a lightweight commutator. The utility model discloses a lightweight commutator. The commutator comprises a cylinder provided with a through hole at the center and a mica layer on the side part. A glass fiber plastic layer is arranged around the mica layer, and the side part of the glass fiber plastic layer is provided with a plurality of snap grooves. Commutator segments are arranged inside the snap grooves, and comprise snap plates and hooks. A recessed groove is provided between each hook and the glass fiber plastic layer. An insulation layer is arranged between the snap plates. The commutator is reasonable in structure, so that the weight of the whole commutator is reduced, and thus the whole commutator is better adapted to work under high speed rotation.
Description
Technical field
The utility model belongs to motor apparatus technical field, relates in particular to a kind of lightweight steering gear.
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.Thereby current commutator exists unreasonable structure has caused the weight of whole steering gear heavier, so be unfavorable for working the in the situation that of high speed rotating.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of lightweight steering gear is provided, and its technical scheme is as follows:
A kind of lightweight steering gear, comprise cylinder, it is characterized in that, described cylindrical center is provided with through hole, and described cylindrical sidepiece is provided with mica layer, the outside of described mica layer is provided with fiberglass plastic layer, the sidepiece of described fiberglass plastic layer offers some draw-in grooves, in described draw-in groove, is provided with commutator segment, and described commutator segment comprises clamp and hook, between described hook and fiberglass plastic layer, be provided with groove, between described clamp is adjacent, be provided with insulating barrier.
Optimal way is that described insulating barrier extends to mica layer through fiberglass plastic layer.
The lightweight steering gear that the utility model provides, when in use, described cylindrical sidepiece is provided with mica layer, by mica layer, 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 provided with fiberglass plastic layer, by the further weight saving to whole steering gear of fiberglass plastic layer, steering gear is worked in the situation that being more suitable in high speed rotating.The sidepiece of described fiberglass plastic layer offers some draw-in grooves, in described draw-in groove, be provided with commutator segment, described commutator segment comprises clamp and hook, by hook, can be connected with motor, hook can bear pulling force more than 50N, spot welding pressure more than 500N does not occur loosening abnormal when 500 degrees Celsius of spot welded hots.Between described hook and fiberglass plastic layer, be provided with groove.Can be so that hook be more firm by groove.
Insulating barrier described in the utility model extends to mica layer through fiberglass plastic layer.Can be so that insulation resistance obtains raising by a relatively large margin by insulating barrier.Be conducive to the work of steering gear.
Structure rationalization of the present utility model, makes the weight of whole steering gear obtain alleviating, and makes whole steering gear more be adapted to the work in high speed rotating situation.
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 lightweight steering gear, comprise cylinder 1, it is characterized in that, the center of described cylinder 1 is provided with through hole 2, the sidepiece of described cylinder 1 is provided with mica layer 3, the outside of described mica layer 3 is provided with fiberglass plastic layer 4, the sidepiece of described fiberglass plastic layer 4 offers some draw-in grooves 5, in described draw-in groove 5, be provided with commutator segment 6, described commutator segment 6 comprises clamp 7 and hook 8, between described hook 8 and fiberglass plastic layer 4, be provided with groove 9, between described clamp 7 is adjacent, be provided with insulating barrier.
Optimal way is that described insulating barrier extends to mica layer through fiberglass plastic layer.
The lightweight steering gear that the utility model provides, when in use, described cylindrical sidepiece is provided with mica layer, by mica layer, 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 provided with fiberglass plastic layer, by the further weight saving to whole steering gear of fiberglass plastic layer, steering gear is worked in the situation that being more suitable in high speed rotating.The sidepiece of described fiberglass plastic layer offers some draw-in grooves, in described draw-in groove, be provided with commutator segment, described commutator segment comprises clamp and hook, by hook, can be connected with motor, hook can bear pulling force more than 50N, spot welding pressure more than 500N does not occur loosening abnormal when 500 degrees Celsius of spot welded hots.Between described hook and fiberglass plastic layer, be provided with groove.Can be so that hook be more firm by groove.
