Abstract

The utility model relates to a carbon brush assembly used for contact type voltage regulators. The utility model comprises a carbon brush, a carbon brush holder, a radiating fin and a supporting frame, wherein, the carbon brush and the carbon brush holder are assembled into a body, and both are fixed on the radiating fin; the carbon brush holder penetrate in the supporting frame with an open slot; a helical compression spring is arranged between the supporting frame and the carbon brush holder which penetrates in the open slot of the supporting frame. The utility model has the advantages of easy control of the pressure centre position of the carbon brush, compact structure, etc.

Description

Carbon brush component

The utility model relates to a kind of special-purpose member of contact type voltage regulator.

At present, existing carbon brush component is made up of carbon brush, carboloy holder, bearing support, fin etc. on the market, and volute spring is housed between bearing support and the carboloy holder, the stressed shakiness of the carbon brush of this carbon brush component, and the center is difficult to control.

The purpose of this utility model just provides a kind of compact conformation, good heat dissipation effect, carbon brush centre-of-pressure position carbon brush component accurately.

For achieving the above object, technical scheme provided by the utility model is: a kind of carbon brush component, it comprises carbon brush, carboloy holder, fin, bearing support, carbon brush and carboloy holder are assembled into one, the two is fixed on the fin together, carboloy holder penetrates in the bearing support of band open slot, penetrates between carboloy holder in the bearing support open slot and the bearing support spiral compression spring is housed.

Compare with existing carbon brush component on the market, the utility model adopts a spiral compression spring between carboloy holder and bearing support, so the carbon brush centre-of-pressure position is controlled easily.And the utility model is installed spiral compression spring, compact conformation in the bearing support opening is poor.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Fig. 1 is the vertical view of the utility model carbon brush component.

Fig. 2 is that carbon brush component shown in Figure 1 is along A-A line cutaway view.

Fig. 3 is that Fig. 2 is along B-B line cutaway view.

Fig. 1, Fig. 2, carbon brush component shown in Figure 3, it is made up of carbon brush 1, carboloy holder 2, fin 3, bearing support 4 etc.Carbon brush 1 adopts interference assembling method or soldering connection to be assembled into one with carboloy holder 2, carboloy holder 2 adopts pressure sintering to be fixed into one with fin 3, carboloy holder 2 penetrates in the open slot of bearing support 3, adorn a spiral compression spring 5 between fin 3 and the bearing support 3, to guarantee between carbon brush 1 and the toroid bag 7 enough pressure being arranged.Fastening between bearing support 4 and the bearing 6 with screw, carbon brush component is fixed on the bearing 6 by bearing support 4, and rotates thereupon.

Claims

1, a kind of carbon brush component, it comprises carbon brush (1), carboloy holder (2), fin (3), bearing support (4), carbon brush (1) is assembled into one with carboloy holder (2), the two is fixed on the fin (3) together, carboloy holder (2) penetrates in the bearing support (4) of band open slot, it is characterized in that above-mentioned penetrating between carboloy holder (2) in bearing support (4) open slot and the bearing support (4) be equipped with a spiral compression spring (5).
