Description

Conductive slip ring capable of automatically removing scraps and preventing friction excess

Technical Field

The invention relates to a conductive slip ring, in particular to a conductive slip ring capable of automatically removing scraps and preventing friction redundancy.

Background

The electric transmission device realizes the transmission of electric signals and electric power between two relatively rotating structural bodies, and realizes the sliding electric transmission in a rotary state by the sliding electric friction contact between the brush wires of the brush of the stator part of the slip ring and the rotor part of the slip ring.

In the actual use process of the conductive slip ring, because the relative friction between the fixed part and the rotating part of the conductive slip ring is inevitable, a large amount of black or brown grinding dust is generated at the contact part due to long-time work, the friction redundancy is usually an insulator and is accumulated at the contact part, the slip ring is broken, the common work failure fault mode is realized, the conductive performance and the service life are seriously influenced, and the technical problem is solved. The specific reason for the above problem is caused by the fact that the amount of generated abrasive dust is too large and the abrasive dust cannot be automatically discharged from the contact area in time.

Disclosure of Invention

The invention aims to provide a conductive slip ring which can reduce the generation amount of abrasive dust and has the function of automatically discharging friction excess.

The purpose of the invention is realized as follows:

the utility model provides a from conducting electrical slip ring of chip removal antifriction surplus thing, includes carousel and stator, and the outer end of the reed of "Z" shape is fixed on the inner wall of carousel, is fixed with the slider with the contact of stator outer wall in the inner of reed, through the rotation work of carousel, drives slider and the relative rotation of the stator that does not rotate and contact friction each other, the characteristic is: the edge of the working contact surface of the sliding block is provided with a front arc angle and a rear arc angle, and the middle part of the working contact surface of the sliding block is provided with an inwards concave semicircular chip removal through groove.

The semicircular chip removal through groove is a through groove.

The working contact surface of the slide block and the opposite mounting surface have a micro-inclination angle, and the inclination angle value is 0.2-2 degrees.

The invention has the advantages that: the edge of the working contact surface of the sliding block of the conductive sliding ring is provided with two arc angles, so that the surface of the sliding block serving as a contact is smoother, the abrasion dust generated in the rotating work is obviously reduced, and the service life of the conductive sliding ring is longer; because the semicircular chip removal through groove is formed in the middle of the working contact surface, more abrasive dust generated by the sliding block and the stator is discharged into the semicircular chip removal through groove, the abrasive dust enters the non-contact surface, residual insulating redundancy of the conductive contact surface is obviously reduced, and the conductivity of the conductive sliding ring is ensured, so that the problem that the conductive sliding ring is easy to break during working is solved; because the working contact surface of the sliding block and the mounting surface have a micro-inclination angle which is calculated to be closer to the contact angle of the stator and the sliding block during actual working, the conductive sliding ring can be more reliably contacted during working; because the material of the sliding block is gold ternary alloy AuCuPt with higher hardness, the content of abraded redundant substances is lower, the conductivity of abrasive dust is improved, and the influence of the abrasive dust on conductive work is smaller; the reed is made of QBe2 beryllium bronze, so that the reed has better elasticity than other materials, and the conductive slip ring can be contacted more stably during rotation and work. The conductive slip ring has the characteristics of simple structural design, reliable work, suitability for industrial production and easiness in popularization.
