Description

Long-life motor carbon brush

Technical Field

The utility model relates to a motor carbon brush technical field specifically is a long-life motor carbon brush.

Background

Carbon brushes, also called brushes, are widely used as a sliding contact in many electrical devices. The carbon brush mainly comprises graphite, impregnated graphite and metal (copper and silver) graphite in product application. The carbon brush is a device for transmitting energy or signals between a fixed part and a rotating part of a motor or a generator or other rotating machinery, and the carbon brush is easy to wear and needs to be replaced due to friction between a current collecting ring and a previous carbon brush, so that the problem needs to be solved by prolonging the service life of the carbon brush.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a long-life motor carbon brush.

The technical scheme of the utility model is that: a carbon brush of a long-service-life motor comprises a carbon brush body, wherein a carbon brush frame is installed at the top of the carbon brush body, an inward slide way is arranged in the carbon brush body, a collecting ring is installed on the carbon brush body, an outer frame is arranged below the carbon brush body, a wire is arranged between the outer frame and the bottom of the carbon brush body, and a spring is arranged between the bottom of the carbon brush body outside the wire and the outer frame.

Further, the carbon brush body is circular, and the middle part of the carbon brush body is hollow.

Furthermore, the slide way is an inward smooth arc-shaped groove, and the shape of the slide way is matched with the shape of the outer edge of the power collecting ring.

Furthermore, the collector ring is tightly contacted with a slideway of the carbon brush body, and the depth of the slideway is not more than one half of the thickness of the carbon brush body.

The utility model discloses an useful part: this application simple structure through the contact mode who changes between collecting ring and the carbon brush body, effectively prolongs motor carbon brush's life.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of a side view of the carbon brush body of the present invention;

wherein: 1. the carbon brush comprises a collector ring 2, a carbon brush body 3, a slide way 4, a carbon brush holder 5, a lead 6, a spring 7 and an outer frame.

Detailed Description

In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.

As shown in fig. 1-2, a long-life carbon brush for a motor includes a carbon brush body 2, the carbon brush body 2 is circular, the middle of the carbon brush body 2 is hollow, a carbon brush holder 4 is installed on the top of the carbon brush body 2, an inward slideway 3 is arranged in the carbon brush body 2, the slideway 3 is an inward smooth arc-shaped groove, the shape of the slideway 3 is matched with the shape of the outer edge of the current collecting ring 1, the current collecting ring 1 is installed on the carbon brush body 2, the current collecting ring 1 is in close contact with the slideway 3 of the carbon brush body 2, the depth of the slideway 3 is not more than one half of the thickness of the carbon brush body 2, an outer frame 7 is arranged below the carbon brush body 2, a wire 5 is arranged between the outer frame 7 and the bottom of the carbon brush body 2, and a spring 6 is arranged between the bottom of the carbon brush body 2 outside the wire 5 and the outer frame 7.

Through set up the slide in carbon brush body, the collecting ring contacts with the slide in carbon brush body, and be slick and sly shape in the slide, the collecting ring is almost the point contact with it, can reach the brush effect, can prevent the wearing and tearing of brush again, effectively improves the life of motor carbon brush.
