Description
Technical field
The utility model is relevant with collector machine, is meant that in more detail a kind of carbon brush that improves the effect that electrically conducts keeps seat.
Background technology
Shown in Figure 1 is that a kind of known carbon brush keeps seat 1, and its composition includes a bracing frame 2, two carbon brush 3, two leads 4 and two torque springs 5.Wherein, the both sides of bracing frame 2 respectively have a tank 2a, and each tank 2a has a microscler profile groove 2b; This two carbon brush 3 is positioned over respectively among each tank 2a; These two leads, 4 external packets insulating layer coatings, and lead 4 one end 4a are fixed in the top of bracing frame 2, and other end 4b is then affixed with the first half of carbon brush 3; This two torque spring 5 is wound in respectively on the steady pin 6 that is arranged on bracing frame 2, and its jacking force impels carbon brush 3 to move down, and then guarantees that the bottom of carbon brush 3 can keep the surface of contact collector ring 7.
Really said structure can conduct to collector ring 7 with electric current through carbon brush 3 effectively, and only, it still has not attain and improves and remain improvements again, that is:
1, well-known, the jacking force size of torque spring 5 is relevant with the angle theta size between its two leg 5a, the 5b, and has a maximum expansion angle between this two leg 5a, 5b.Under state shown in Figure 2, when this angle theta is added wide-angle along with carbon brush 3 by abrasion gradually, bestow the active force of carbon brush 3 with reducing torque spring 5; Jointly; To make and so, will definitely influence the effect that electrically conducts in butt collector ring 7 surfaces no longer really, carbon brush 3 bottoms.Especially under the higher situation in steady pin 6 positions, launch angle and weaken jacking force making leg 5a and the leg 5b of this torque spring 5 be expanded to this maximum more easily.
