Rotary conducting structure

Abstract

The invention provides a rotary conducting structure. The rotary conducting structure comprises an inner insulation sleeve and an outer insulation sleeve, the axes of the inner and outer insulation sleeves extend in the front and back direction, the inner insulation sleeve is arranged coaxial with the outer insulation sleeve, and at least one bearing is arranged in an annular space formed between the inner and outer insulation sleeves. Each bearing includes a circumferentially enclosed bearing outer ring, a circumferentially enclosed bearing inner ring and a conducting ball, wherein the bearing outer ring is fixedly assembled at the internal circumferential surface of the outer insulation sleeve, the bearing inner ring is fixedly assembled at the external circumferential surface of the inner insulation sleeve, and the conductive ball is connected between the bearing inner ring and the bearing outer ring. The bearing inner and outer rings of the rotary conducting structure are enclosed circumferentially and fixed to the inner insulation sleeve and the outer insulation sleeve which are arranged coaxially, the radial sizes of the different positions of the annular space formed between the bearing inner and outer rings are the same, the ball makes stable and unchanged contact with the bearing inner and outer rings when rotating circumferentially in the annular space in a circulated manner, and the rotary conducting performance is high.

Description

technical field [0001] The invention relates to the field of conductive connection, in particular to a rotating conductive structure. Background technique [0002] At present, in the field of electric slip rings, the brush and the conductive ring mainly adopt the sliding contact method, and composite brush blocks or precious metal monofilaments or fiber brushes are used to make sliding conductive contact with the conductive ring. When the electric slip ring is applied to high-power transmission, the above three Both need to use multi-channel parallel to transmit power together. Due to the influence of machining accuracy and assembly accuracy, the actual power transmitted by each channel is not the same. When the design redundancy is small, due to the difference in actual transmission power, some path brushes will burn out, resulting in product failure; when the design redundancy is large, the axial dimension needs to be increased, and the product cost will increase according...
