Hollow single-channel rotary joint

Abstract

The invention discloses a hollow single-channel rotary joint. The hollow single-channel rotary joint comprises a rotor outer shell and a stator outer shell which are installed in a facing mode, wherein a bearing is arranged in a space formed by the outer side of the rotor outer shell and the inner side of the stator outer shell, an insulating supporting plate is installed in an inner side cavity of the rotor outer shell through screws, and the other side of the insulating support plate is provided with a rotor center needle through a screw; a stator hole is formed in the side, away from the rotor center pin, of the stator outer shell, a PEEK supporting piece is fixedly installed in the stator hole, a stator center pin is fixedly installed on the PEEK supporting piece, and a special-shaped elastic piece is fixedly connected to the inner side of the stator center pin; and a friction ring welded with the insulating support plate is arranged between the rotor center pin and the stator center pin; and one end of the special-shaped elastic piece is in contact with the friction ring. The problems of miniaturization, consistency, reliability, stability, productivity improvement, cost reduction and the like of all channel indexes in the multi-channel rotary joint are solved, and economic benefit maximization is achieved.

Description

technical field [0001] The invention relates to the technical field of signal transmission, in particular to a hollow single-channel rotary joint. Background technique [0002] At present, the rotary joints in the domestic common frequency band are large in size and poor in performance indicators. The fixed and rotary joints must not only rotate smoothly, but also ensure a good electrical connection between the moving and fixed parts, so that the signal can be transmitted stably; Some assembly methods are very cumbersome, and the cavity size is too long, which increases the time and path of signal transmission, and at the same time increases the cost. Consistency, the increase of production cost, cause unnecessary waste of cost. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] In view of the above-mentioned technical problems in the related art, the present invention proposes a ho...
