Abstract

The utility model relates to a slip ring, which comprises a dust cover, a rear end cover, a rear baffle, a first bearing, an electric brush frame, an aluminum ring, a front end cover, a second bearing, and a conducting ring, wherein, the rear end cover is arranged at the bottom end in the dust cover; the rear baffle is arranged on the rear end cover; the first bearing is arranged between the rear end cover and the rear baffle; the electric brush frame is arranged at the upper end of the first bearing; athe aluminum ring is positioned at the upper end of the electric brush frame; the front end cover is arranged at the upper end of the aluminum ring; the front baffle is positioned in the front end cover; the second bearing is arranged between the front end cover and the front baffle, and the conducting ring is positioned at the periphery of the electric brush frame. Because electric brush wire on the electric brush frame contacts with the conductng ring to form a symmetric dual-contact ring groove, the electric brush wire contacts with and is communicated with the conducting ring to transmit signals and current. Thus the utility model prevents the electric brush wire in the prior art from directly transmitting signals and current so as to prevent the potential danger to the electric brush wire in the slip ring when the slip ring rotates. Simultaneously, the mechanical performance of the whole slip ring can be improved. In addition, the utility model has the advantage of simple structure.

Description

Slip ring

[technical field]

The utility model relates to a kind of slip ring.

[background technology]

[utility model content]

Technical purpose of the present utility model is in order to solve the problem that above-mentioned prior art exists, and provide a kind of hidden danger of damaging the brush wire that is arranged at slip ring inside not only can avoid rotating the time to take place, but also can improve mechanical performance and have slip ring simple in structure.

In order to realize above-mentioned technical problem, the utility model provides a kind of slip ring, it comprises dust cover, be arranged at the rear end cap of dust cover inner bottom, be arranged at the backboard on the rear end cap, be arranged at the clutch shaft bearing between rear end cap and the backboard, be arranged at the brush carrier of clutch shaft bearing upper end, be arranged at the aluminium ring of brush carrier upper end, be arranged at the front end housing of aluminium ring upper end, be arranged at the front apron of front end housing inside, be arranged at second bearing between front end housing and the front apron and the conducting ring of brush carrier periphery, what be arranged at that brush wire and conducting ring on the brush carrier be in contact with one another formation is used to transmit the annular groove that the symmetric double of signal and electric current contacts.

According to above-mentioned major technique feature, described brush carrier comprises main shaft, is arranged at the brush plate of main shaft periphery and divides supplementary biography to be located at the brush wire with elastic pressure of the plural number bundle in the brush plate.

According to above-mentioned major technique feature, be arranged at a plurality of insulators of placing every stack between the upper and lower mutually that are provided with between the brush wire of brush carrier periphery and the brush wire.

According to above-mentioned major technique feature, described conducting ring is made of copper ring.

According to above-mentioned major technique feature, the periphery of described main shaft offers the storage tank that is used to accommodate plural number bundle brush wire respectively.

According to above-mentioned major technique feature, also be provided with the spline sheet on the described main shaft.

According to above-mentioned major technique feature, described insulator is made of insulating trip

Useful technique effect of the present utility model: be in contact with one another the annular groove that the symmetric double of formation contacts because of being arranged at brush wire and conducting ring on the brush carrier, make it brush wire and conducting ring can be in contact with one another conducting, transmit the effect of signal and electric current, avoid brush wire of the prior art directly to transmit signal and electric current, take place thereby reach the hidden danger of damaging the brush wire that is arranged at slip ring inside when avoiding rotating; Simultaneously, also can improve the mechanical performance of whole slip ring.In addition, the utility model also has purpose simple in structure.

Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
