In the rolling type conducting ring assembly, the retainer is arranged on the bosses of the inner ring and the outer ring, so that relative positions among the rollers are fixed to make the plurality of rollers kept mutual isolation during rolling and avoid abrasion caused by friction; higher assembling precision can be achieved under a condition of lower processing precision of the rollers; and the reliability of a rolling ring is improved.
Description
Technical field
The invention belongs to electromechanical integration technology area, particularly a kind of conducting ring for the windsurfing driving mechanism transmission energy and signal of telecommunication in the star.
Background technology
The solar array driving mechanism is the requisite vitals of long-life three axis stabilized satellite, and major function is to support and drive the solar battery array Direct to the sun, and the energy that solar battery array is obtained and electric signal transmission are in celestial body.Owing to can't back up, the solar array driving mechanism is one of Single Point of Faliure source of minority on the star, will directly cause whole star to lose whole energy and lost efficacy in case lose efficacy.
The critical component of the conducting ring transmission energy that is the windsurfing driving mechanism in the star and the signal of telecommunication.The conducting ring of domestic and international most satellite sailboard driving mechanism application is the slidingtype conducting ring now, mainly by apply certain elastic pressure to brush, makes itself and conducting ring ring plate reliably contact the formation electric pathway and comes transmission current.But the problem such as that it exists is easy to wear, the velocity-stabilization degree is poor, the life-span is limited.
The rolling type conducting ring belongs to the device for transporting electricity at heavy of a new generation, can substitute slip ring is that the windsurfing driving mechanism transmits the energy and the signal of telecommunication in star, its maximum advantage is exactly long-life, low wearing and tearing, is mainly used on the solar array driving mechanism of long-life, high-power, high-speed stability requirement.
The United States Patent (USP) of application number 255021 discloses a kind of large current delivery and has rolled loop device, mainly comprises roller, interior ring, outer shroud and maintenance roller.Its operation principle is: signal or power are transferred to outer shroud from interior ring by roller, the purpose of the interrupted transmission of settling signal between static and motion.This mode is mainly by keeping roller to make a plurality of rollers keep relative position relation stable when moving.Therefore, when many roller assemblings, because the tolerance between roller is high, higher to the machining accuracy of roller and maintenance roller, assembly difficulty is large, produces easily waste product, is unfavorable for practical application, has strengthened simultaneously the wearing and tearing of roller, has reduced the reliability of rolling ring.
Summary of the invention
Technology of the present invention is dealt with problems and is, overcomes the deficiencies in the prior art, provides a kind of processing simple, and assembly difficulty is little, and volume is little, and small-size rolling type conducting ring assembly is used in the space that reliability is high.
Technical solution of the present invention is: small-size rolling type conducting ring assembly is used in a kind of space, comprises roller, interior ring, outer shroud and retainer; Interior ring and outer shroud are concentric; The outer surface of interior ring and the inner surface of outer shroud are processed with respectively the raceway groove that two-way holds roller, between two raceway grooves boss are set; Retainer is fixed on the boss of interior ring and outer shroud by equally distributed locating wheel; Roller is installed between locating wheel; In the up and down both sides of retainer, roller sleeve is on roller, and roller relies on the strain of self to be stuck in the raceway groove of interior ring outer surface and outer ring inner surface; Interior ring inner surface and outer ring outer surface arrange weld groove and are used for welding lead.
The quantity of described roller is 1-12.
The quantity of described locating wheel is 3-4.
Described rolling type conducting ring can be according to the way multiple-layer stacked of the windsurfing driving mechanism transmission energy and signal of telecommunication in the star, insulate by sheet ring-type end face insulating barrier between every layer of ring and the ring.
The present invention's beneficial effect compared with prior art is:
(1) the present invention arranges the form of retainer by the boss at interior ring and outer shroud, fix the relative position between many rollers, make a plurality of rollers when rolling, keep each other mutually isolation, the wearing and tearing of avoiding rubbing and bringing, can in the lower situation of roller machining accuracy, realize higher assembly precision, improve the reliability of rolling ring.
(2) the present invention on roller, therefore can arrange roller sleeve more roller, and then improve the current delivery power of circuit by roller is installed between locating wheel in limited space.
(3) the present invention can according to the actual demand of electric current, by the quantity of change locating wheel and roller, adjust the installation quantity of roller on every layer of conducting ring, thereby improve the adaptability of rolling ring flexibly.
