Abstract
The utility model relates to a kind of novel light steering gear, comprise cylinder, the center of described cylinder is provided with through hole, a mica sleeve is socketed outward at described cylinder, an insulating sleeve is socketed in the outside of mica sleeve, to be connected two commutator segments by one group of retainer ring outside insulating sleeve, to be equipped with a commutation flange in the end of each described commutator segment.Advantage of the present utility model: diverter structure provided by the utility model is reasonable, lighter in weight, makes steering gear still can stablize in high speed rotating situation and works for a long time.
Description
Technical field
The utility model relates to machine field, particularly relates to a kind of novel light steering gear.
Background technology
Commutator is the vitals of direct current machine, and effect is the alternating current that is converted to by the direct current that brush passes through 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 under the effect of permanent magnet, by attracting and repulsive force rotation, when it forward to balance with magnet time, the contact originally led on the line more corresponding commutator 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.Current commutator also exists unreasonable structure, thus causes its weight comparatively large, and insufficient strength, is easy to wearing and tearing, the shortcoming that the life-span is short.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of novel light steering gear proposed.
To achieve these goals, the utility model have employed following technical scheme:
A kind of novel light steering gear, comprise cylinder, the center of described cylinder is provided with through hole, the sidewall of described cylinder comprises one group of cylindrical shell annulus, all be connected and fixed by one group of cylindrical shell connecting rod between two cylindrical shell annulus of arbitrary neighborhood, a mica sleeve is socketed outward at described cylinder, described mica sleeve comprises one group of mica annulus, all be connected and fixed by one group of mica connecting rod between two mica annulus of arbitrary neighborhood, gap corresponding matching between described mica annulus with described two corresponding adjacent cylindrical shell annulus, an insulating sleeve is socketed in the outside of mica sleeve, described insulating sleeve is identical with the structure of described cylinder, it comprises one group of edge collar, all be connected and fixed by one group of edge cover connecting rod between two edge collars of arbitrary neighborhood, and the gap corresponding matching between the described edge collar with described two corresponding adjacent mica annulus, to be connected two commutator segments by one group of retainer ring outside insulating sleeve, a commutation flange is equipped with in the end of each described commutator segment.
Preferably, described cylinder is suppressed by powder granulates and is formed.
Preferably, described insulating sleeve is made up of fiberglass plastic.
Preferably, the outside of each described retainer ring is equipped with one group of T-shape fixture block, is equipped with one group of T-shape draw-in groove, described T at the medial surface of each described commutator segment " type draw-in groove and corresponding T-shape fixture block slip snap-fit engagement.
The utility model has the advantage of: diverter structure provided by the utility model is reasonable, lighter in weight, steering gear still can be stablized in high speed rotating situation and work for a long time.

Fig. 1 is basic structure schematic diagram of the present utility model;
Fig. 2 is Fig. 1 using state schematic diagram;
Fig. 3 is commutator segment structural representation.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of novel light steering gear that the utility model provides, comprises cylinder 1, and described cylinder 1 is suppressed by powder granulates and formed.The center of described cylinder 1 is provided with through hole 1.1, the sidewall of described cylinder 1 comprises one group of cylindrical shell annulus 1.2, all be connected and fixed by one group of cylindrical shell connecting rod 1.3 between two cylindrical shell annulus 1.2 of arbitrary neighborhood, at a described cylinder 1 outer socket mica sleeve 2, described mica sleeve 2 comprises one group of mica annulus 2.1, all be connected and fixed by one group of mica connecting rod 2.2 between two mica annulus 2.1 of arbitrary neighborhood, gap corresponding matching between described mica annulus 2.1 with described two corresponding adjacent cylindrical shell annulus 1.2, an insulating sleeve 3 is socketed in the outside of mica sleeve 2, described insulating sleeve 3 is made up of fiberglass plastic.Described insulating sleeve 3 is identical with the structure of described cylinder 1, it comprises one group of edge collar 3.1, all be connected and fixed by one group of edge cover connecting rod 3.2 between two edge collars 3.1 of arbitrary neighborhood, and the gap corresponding matching between the described edge collar 3.1 with described two corresponding adjacent mica annulus 2.1, to be connected two commutator segments 4 by one group of retainer ring 6 outside insulating sleeve 3, to be equipped with a commutation flange 5 in the end of each described commutator segment 4.
The outside of each described retainer ring 6 is equipped with one group of T-shape fixture block 6.1, is equipped with one group of T-shape draw-in groove 4.2, described T at the medial surface of each described commutator segment 4 " type draw-in groove 4.2 and corresponding T-shape fixture block 6.1 slide snap-fit engagement.
The outside socket mica sleeve 2 of described cylinder 1, can play certain insulating effect preferably by mica sleeve 2 and alleviate the weight of whole steering gear.The effect that whole steering gear better can reach optimum when in use can be made.The insulating sleeve 3 of described mica sleeve 2 outside is made for fiberglass plastic, and steering gear is worked when being more suitable in high speed rotating.Described insulating sleeve 3 connects commutator segment 4 by retainer ring 6, is connected, can bears larger pulling force and spot welding pressure, when spot welded hot 500 degrees Celsius, loosening phenomenon can not occur by commutation flange 5 with motor.
