Abstract
The utility model belongs to steering gear apparatus technical field, relates in particular to a kind of steering gear.The utility model discloses a kind of steering gear, comprise cylinder body, cylinder body is formed by the compacting of powder granulates, and the center of described cylinder body offers through hole, one outside of described cylinder body is connected with mica sheet, and the upper end of described mica sheet is connected with commutator segment; Described cylinder body and the junction of mica sheet are provided with fixing collar; Another outside of described cylinder body offers I-groove, and in described I-groove, card is established and is connected with copper bar, and the upper end of described copper bar is connected with commutator segment, and described fixing collar is fixedly located in the I-groove of copper bar and cylinder body junction.The beneficial effects of the utility model are: make the structure of steering gear more reasonable, stable, can extend its service time.
Description
Technical field
The utility model belongs to steering gear apparatus technical field, relates in particular to a kind of 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 attracting and repulsive force rotation, in the time that 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 contact corresponding to coil, so ceaselessly repeat down, DC motor has just been turned over.The commutator existing at present exists unreasonable structure, makes its insufficient strength, 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, provides a kind of rational in infrastructure, the steering gear that can extend its service time, and its technical scheme is as follows:
A kind of steering gear, comprises cylinder body, it is characterized in that, described cylinder body is formed by the compacting of powder granulates, the center of described cylinder body offers through hole, and an outside of described cylinder body is connected with mica sheet, and the upper end of described mica sheet is connected with commutator segment; Described cylinder body and the junction of mica sheet are provided with fixing collar; Another outside of described cylinder body offers I-groove, and in described I-groove, card is established and is connected with copper bar, and the upper end of described copper bar is connected with commutator segment, and described fixing collar is fixedly located in the I-groove of copper bar and cylinder body junction.
The steering gear that the utility model provides, an outside of described cylinder body is connected with mica sheet, and another outside of described cylinder body offers I-groove, and in described I-groove, card is established and is connected with copper bar.Cylinder body connects different materials by both sides, can improve the abrasion resistance of whole steering gear, thereby extends its service time.And cylinder both sides are connected with copper bar with mica sheet by different structures, can make the structure of whole steering gear more rationally stable.
The beneficial effects of the utility model are: make the structure of steering gear more reasonable, stable, can extend its service time.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
As shown in Figure 1, a kind of steering gear, comprises cylinder body 1, described cylinder body 1 is formed by the compacting of powder granulates, the center of described cylinder body 1 offers through hole 2, and an outside of described cylinder body 1 is connected with mica sheet 3, and the upper end of described mica sheet 3 is connected with commutator segment 4; Described cylinder body 1 is provided with fixing collar 5 with the junction of mica sheet 3; Another outside of described cylinder body 1 offers I-groove 6, in described I-groove 6, card is established and is connected with copper bar 7, the upper end of described copper bar 7 is connected with commutator segment 4, and described fixing collar 5 is fixedly located in the I-groove 6 of copper bar 7 and cylinder body 1 junction.
Cylinder body is formed by powder granulates compacting, weight reduction when can making whole steering gear more closely solid.
The steering gear that the utility model provides, an outside of described cylinder body is connected with mica sheet, and another outside of described cylinder body offers I-groove, and in described I-groove, card is established and is connected with copper bar.Cylinder body connects different materials by both sides, can improve the abrasion resistance of whole steering gear, thereby extends its service time.And cylinder both sides are connected with copper bar with mica sheet by different structures, can make the structure of whole steering gear more rationally stable.
