An integrated shaft system for support and signal transmission

Abstract

The invention provides a support-signal transfer integrated shaft system. The support-signal transfer integrated shaft system comprises a first bearing, a power ring piece, an electric brush, a ring piece support, a housing, a signal ring piece and a bearing, a mounting flange, a hollow shaft, an insulating ring piece, a brush holder, a ring outlet wire and a brush outlet wire; the housing is fixedly connected with the mounting flange, and the fixed connection structure composed of the housing and the mounting flange is capable of rotating relatively to the hollow shaft; the power ring piece, the signal ring piece and the insulating ring piece are all of a circular ring piece structure and stacked to sleeve the ring piece support; the electric brush is a V-shaped alloy wire, the point of the V-shaped structure is welded on the brush holder, while the two open ends of the V-shaped structure are embedded in grooves of the power ring piece or the signal ring piece and tangential with the grooves, and the ring outlet wire and the brush outlet wire are used for realizing the transfer of a power signal and a control signal. The support-signal transfer integrated shaft system is capable of effectively reducing reuse of shaft system parts, greatly reducing the complexity of the structure and the difficulty of processing and assembling, remarkably improving the reliability of the system and reducing the space volume of the product, and reducing the weight and the economic cost of the product.

Description

technical field [0001] The invention relates to a shafting structure, in particular to an azimuth shafting structure suitable for a communication antenna stability control system in motion. Background technique [0002] On equipment with continuous rotary motion, traditional signal transmission devices usually use slip rings or joints. The former is a transmission device for low-frequency and DC signals, and the latter is a transmission device for high-frequency signals, which is not covered by this patent. Slip ring belongs to the application category of electrical contact sliding connection. It is also called collector ring, rotating electrical interface, collector ring, confluence ring, etc. It is a precision power transmission that realizes the image, data signal and power (power) transmission of two relative rotating mechanisms device. It is especially suitable for applications where unlimited continuous rotation is required, and at the same time power or data needs to...

AI Technical Summary

Problems solved by technology

Increased design cost and processing cost; at the same time, the weight and space size of the equipment are greatly increased, which is not conducive to the design direction of lightweight and low-profile equipment

Moreover, the two sets of shaft systems need to be docked and the coaxiality should be precisely adjusted, which also increases the workload of assembly adjustment
