Abstract

The utility model relates to a carbon brush assembly with a heat radiating sheet. The utility model comprises a carbon brush, a carbon brush handle, and a heat radiating sheet, wherein, he carbon brush is embedded on the carbon brush handle, and the carbon brush handle is connected with the heat radiating sheet; a reed which is fixed on the heat radiating sheet extends out a cantilever on the heat radiating sheet; the reed is provided with a bearing disk which is sheathed on a bearing axle, and the bearing disk is fixed on the bearing axle; simultaneously, the carbon brush contacts a wire bag, and the reed which is in predeformation accumulates spring force. When the carbon brush is worn, the reed releases the spring force to cause the carbon brush move with the heat radiating sheet, and the carbon brush is immediately in an elastic feeding state. Distinctly, an elastic feeding device is of simple structure. In addition, because no relative movement exists between the carbon brush and the heat radiating sheet, the utility model has the advantages of good heat conduction and good heat radiating effect.

Description

Flange-cooled carbon brush component

The utility model relates to a kind of flange-cooled carbon brush component, particularly the flange-cooled carbon brush component that contacts with the line bag polished surface of voltage regulator and pressurizer.

Carbon brush is a wear-out part, in the process of wearing and tearing, continue to keep excellent contact between the collinear bag of carbon brush in order to make, carbon brush must be in continuous state to the feeding of line bag direction, realize that this feeding has two kinds of methods, a kind of is that the carboloy holder of setting-in carbon brush is located at the slideway of fin to line bag direction slippage feeding in the effect lower edge of feeding spring; Another kind is fin is fixed in support plate in the effect lower edge of feeding spring guide pillar slippage, and make confession setting-in carbon brush and keep feeding to line bag direction with the carboloy holder that fin connects, 98215468.2 disclosed technology that Here it is, it has the characteristics of carbon brush good heat dissipation effect, but realizes the elastic feeding apparatus structure more complicated that the carbon brush feeding is adopted.

The purpose of this utility model provides a kind of carbon brush good heat dissipation effect, and the simple again flange-cooled carbon brush component of structure.

Solution of the present utility model is that described carboloy holder connects with fin, has a reed that is fixed on the fin to stretch out from the fin upper cantilever, and reed is provided with for the supporting disk that is set in bolster.

Above-mentioned supporting disk is set in bolster and is fixed, with the contact of the collinear bag of carbon brush and make the pre-deformation savings of reed spring force, when carbon brush wore and tore, reed was that retracting spring power makes carbon brush move with fin simultaneously, carbon brush promptly is in the elastic feeding state, obviously, this elastic feeding apparatus structure is simple, in addition, because carbon brush is with there not being relative motion between the fin, therefore, heat conduction is good, and radiating effect is also all right.

Illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Fig. 1: structure chart of the present utility model;

The right side view of Fig. 2: Fig. 1.

As shown in the figure, described flange-cooled carbon brush component has carbon brush 1, carboloy holder 2 and fin 3, carbon brush 1 is inlaid on the carboloy holder 2, carboloy holder 2 connects with fin 3, have a reed 4 that is fixed on the fin 3 to stretch out from fin 3 upper cantilevers, reed 4 is provided with for the supporting disk 5 that is set in bolster.The end face of this supporting disk 5 is the installation base surfaces that connect with reed 4, except being provided with axis hole 6, also being provided with and being used for the radially fixing radial location screw 7 of bolster on the supporting disk 5; Carbon brush 1 is flush-mounted in the carbon brush groove that is located at carboloy holder 2, carboloy holder 2 can adopt detachable connection with the connection of fin 3, also can adopt not detachable connection, the advantage of detachable connection is the finished machined that makes things convenient for carbon brush, instant packed transportation, be easy to remove and repair, present embodiment adopts screw to connect, and belongs to detachable connection.

Claims

1, a kind of flange-cooled carbon brush, have carbon brush, carboloy holder and fin, carbon brush is inlaid on the carboloy holder, it is characterized in that: the same fin of described carboloy holder (2) (3) connects, have a reed (4) that is fixed on the fin (3) to stretch out from fin (3) upper cantilever, reed (4) is provided with for the supporting disk (5) that is set in bolster.
