Problems solved by technology

The roller uses a thin-walled elastic ring. Since the wall thickness must not only meet the electrical path impedance, but also must achieve the required radial stiffness and stress requirements to meet the required fatigue life requirements, the selection of materials and assembly requirements are more demanding. high, cost increase

Abstract

The invention provides a high-power rolling type collector ring device comprising first connectors (1), second connectors (2), connecting shafts (3), maintaining frames (4), internal rings (5), external rings (6), springs (7), first ear holes (8), second ear holes (9) and main shafts (14). The connecting shafts (3) and the springs (7) are arranged between pairs of the first connectors (1) and the second connectors (2), and the side surface ends of the first connectors (1) and the side surface ends of the second connectors (2) are pressed to the internal side surface of the grooves of the internal rings (5) and the internal side surfaces of the grooves of the external rings (6) so that current and signal transmission is completed. The springs are installed in the pairs of the connectors of connector rings, and the side surfaces of the connectors are enabled to be contacted with rails via the springs without major influence on fatigue and elasticity of the connectors so that the service life is prolonged. Meanwhile, only the conduction characteristic is considered in connector ring material selection so that material selection range is enlarged.

Description

technical field [0001] The invention relates to a signal and power transmission device between full-degree-of-freedom rotating mechanisms, in particular to a high-power rolling slip ring device. Background technique [0002] The slip ring is a device for transmitting signals and power between two full-degree-of-freedom rotating mechanisms. It is an essential and important part of equipment such as satellites, radars, and space stations. The transmission performance and service life of the slip ring directly affect the performance of these devices. and longevity. At present, the slip ring mainly includes a sliding slip ring and a rolling slip ring, among which [0003] The manufacturing technology of the sliding collector ring is relatively mature, and it is being widely used on the interface of two full-degree-of-freedom rotating mechanisms. However, the friction torque of the sliding collector ring is relatively large, and the sliding contact method causes serious surface ...
