A high-power rolling slip ring device

Abstract

The invention provides a high-power rolling collector ring device. The high-power rolling collector ring device comprises rolling circle rotor assemblies, a fixed supporting seat and multiple rolling block assemblies. Each rolling circle rotor assembly comprises a main shaft, multiple conductive rings, multiple separating rings and a fastening component, wherein the conductive rings and the separating rings are arranged on the main shaft in a sleeved mode at intervals, and the main shaft is connected with the fixed supporting seat through first bearings. Each rolling block assembly comprises a stand, two guiding rods, two adjusting nuts, two compressed springs, a base plate, two first checking rings, a rolling block and multiple flexible rings, wherein the stand is connected with the fixed supporting seat, the guiding rods are connected with the stand, the adjusting nuts, the compressed springs, the base plate and the first checking rings are sequentially arranged on the guiding rods in a sleeved mode, the adjusting nuts are connected with the guiding rods in a threaded mode, a rotary shaft of the rolling block is connected with the base plate through second bearings, the flexible rings are arranged on the inner side of the rolling block in an embedded mode, and the outer side of the rolling block can be in contact with the conductive rings. Due to the rolling contact between the conductive rings and the rolling blocks and the rolling contact between the rolling blocks and the flexible rings, transmitting of an electric signal and power is carried out, the abrasion is low, abrasive fragments do not exist, the service life is long, and the electric performance is good.

Description

technical field [0001] The invention relates to a slip ring device, in particular to a high-power rolling slip ring device. Background technique [0002] Slip rings have a wide range of demands in the fields of aerospace, aviation, navigation and various precision instruments. The bus ring is used to realize the transmission of electric power or electric signal between two relatively rotating parts, so as to avoid twisting and breaking the wire during relative rotation. [0003] At present, the commonly used slip ring device mainly realizes this transmission function through the frictional contact between the fixed wire brush (or carbon brush) and the rotating ring. However, when this kind of slip ring works, sliding friction is formed between the contact surfaces. As the working time prolongs, wear debris will be generated, and the wear debris will continue to accumulate on the contact surface, which will reduce the electrical performance of the slip ring device and shorte...

However, when this kind of slip ring works, sliding friction is formed between the contact surfaces. As the working time prolongs, wear debris will be generated, and the wear debris will continue to accumulate on the contact surface, which will reduce the electrical performance of the slip ring device and shorten the life of the slip ring device. service life
