Description

Technical Field

[0001] The invention relates to a stable conductive structure for ensuring the combination of multiple flexible bodies and isolated idler wheels, which is applicable to the technical field of rolling electrical contact, and in particular to a contact load-stabilized rolling conductive ring contact structure for the combination of multiple flexible bodies and isolated idler wheels. Background Art

[0002] High-power rolling rotational transmission technology uses multiple flexible bodies to carry current and is a new type of rotating electrical transmission structure that rolls stably. Compared with traditional sliding electrical transmission technology, rolling electrical transmission technology has the advantages of large transmission current (60A~600A), small friction resistance torque (1 order of magnitude smaller than sliding friction), and stable contact performance (6~24 multiple flexible bodies). It has gradually developed into the preferred solution for electric rotational transmission in the field of spacecraft, aircraft and radar equipment.

[0003] Foreign high-power rolling and rotating transmission products have been basically occupied by American companies such as Diamond and Moog for a long time, achieving technology and price monopoly, which has seriously restricted my country's design and manufacturing capabilities of high-power rolling and rotating transmission products. When working, high-power rolling and rotating transmission products realize data signal and power transmission through the rolling contact between multiple flexible bodies and inner and outer tracks, and the movement stability between the multiple flexible bodies and the inner and outer tracks directly affects the stability of power transmission of high-power rolling and rotating transmission products. When the structural dimensions between the multiple flexible bodies and the inner and outer tracks do not match, a large amount of sliding occurs in the multiple flexible bodies, resulting in unstable rolling structures, which in turn leads to structural damage and causes failure of high-power rolling and rotating transmission products. Therefore, how to ensure the stability of the structural movement of the multiple flexible bodies can effectively improve the transmission power and reliability of high-power rolling and rotating transmission products. Summary of the invention

[0004] The purpose of the present invention is to provide a stable conductive structure composed of multiple flexible bodies and isolation idlers. Based on the motion-stable conductive structure, a method for controlling the motion dimensions among the multiple flexible bodies, isolation idlers, track plates, inner tracks and outer tracks is proposed to achieve structural motion stability composed of the multiple flexible bodies, isolation idlers, track plates, inner tracks and outer tracks at different rotation speeds, improve the efficiency and reliability of pure rolling, and realize high-power transmission of a rolling conductive ring based on multiple flexible bodies and isolation idlers.

[0005] The object of the present invention is achieved in this way: a stable conductive structure composed of multiple flexible bodies and isolated idlers, composed of an outer track, a flexible body, an inner track, a track plate, an isolated idler and an insulating ring, characterized in that the outer track, the flexible body and the inner track are made of copper material with good conductive properties, the outer track and the inner track are combined and installed in the same horizontal plane, 12 flexible bodies are arranged in sequence according to 360° equally divided angles and installed between the outer track and the inner track; 12 isolated idlers rely on two tracks and are installed between two flexible bodies to form a stable conductive structure composed of multiple flexible bodies and isolated idlers; the outer track is installed on the insulating ring, and the inner track is installed on the track plate, and they are combined to form a stable conductive structure composed of multiple flexible bodies and isolated idlers. The 12 flexible bodies of the stable structure are installed on the tracks of the inner track and the outer track at intervals of 30° through their own elastic deformation; the 12 isolation idler wheels of the stable structure are installed on the track plate and fixed to the cylindrical surfaces of the flexible bodies spaced apart from each other to form a stable structure; the stable structure, based on the inner track, 12 flexible bodies, 12 isolation idler wheels, the track plate and the outer track, forms a wheel train structure to achieve precise control of the contact load of the rolling conductive structure.

[0006] Furthermore, the outer track, multiple flexible bodies, isolated idler wheels and inner track form a stable conductive structure, so that when the inner track, outer track and track plate are in rotational motion, the multiple flexible bodies and isolated idler wheels respectively rotate and revolve, and the current of the inner track is transmitted to the outer track in rotation through multiple flexible bodies in parallel.

[0007] Furthermore, the outer track, multiple flexible bodies, isolation idler wheels and inner track form a stable conductive structure that needs to meet the following speed and diameter mathematical model characteristics: In the above formula, d1 is the inner track diameter, d3 is the outer track diameter, and d J is the track plate diameter, R1 is the radius of the flexible body, d D1 d is the inner diameter of the isolation idler (matched with the flexible ring), D is the diameter of the outer circle of the isolation idler wheel (matching with the guide rail), ω1 is the angular velocity of the inner track and the track plate, ω H is the revolution speed of the flexible body and the isolation idler wheel, ω2 is the rotation speed of the flexible body, and ω3 is the rotation speed of the isolation idler ring.

[0008] Furthermore, in order to effectively improve the reliability of the motion structure of the combination of multiple flexible bodies and isolation idlers, the isolation idler is made of self-lubricating material and can be pre-run in with the multiple flexible bodies so that the surface has good lubrication properties, further improving its conductivity and wear resistance, and can meet the stable rolling of the outer track, flexible body, inner track and isolation idler in the stable conductive structure.

[0012] In the stable conductive structure of the combination of multiple flexible bodies and isolated idler wheels, 12 flexible bodies (2) are installed on an outer track (1) and an inner track (3). When the inner track (3) rotates, the flexible bodies (2) realize self-rotation and revolution, and the electric power of the inner track (3) is rotationally transmitted to the outer track (1) by means of current diversion, thereby realizing the rotational electric transmission of a high-power rolling conductive ring.

[0013] The outer track (1) passes through an insulating ring (6), and the inner track (3) passes through a track plate (4), and is stacked layer by layer in an axial series manner, thereby realizing the engineering application of a stable conductive structure composed of multiple flexible bodies and isolated idler wheels.

[0014] The contact structure dimensions of the outer track (1), the flexible body (2), the inner track (3), the track plate (4), and the isolating idler wheel (5) in the stable conductive structure of the combination of multiple flexible bodies and isolating idler wheels meet the following speed and diameter mathematical model characteristics: In the above formula, d1 is the inner track diameter, d3 is the outer track diameter, and d J is the track plate diameter, R1 is the radius of the flexible body, d D1 d is the inner diameter of the isolation idler (matched with the flexible ring), D is the diameter of the outer circle of the isolation idler wheel (matching with the guide rail), ω1 is the angular velocity of the inner track and the track plate, ω H is the revolution speed of the flexible body and the isolation idler wheel, ω2 is the rotation speed of the flexible body, and ω3 is the rotation speed of the isolation idler ring.

[0015] The mathematical model establishes the principle of combined motion matching of a multi-flexible rolling electric transmission elastic component and an isolation idler wheel, which can effectively improve the reliability of the stable conductive structure of the rolling conductive ring, prevent the rolling conductive structure from being damaged due to the instability of the motion structure of the multi-flexible body-isolation idler wheel, control the sliding ratio to be below 2%, and reduce the risk of arc discharge failure and misalignment of the flexible body or isolation idler wheel. It is a necessary condition for the outer track (1), the flexible body (2), the inner track (3), the track plate (4), and the isolation idler wheel (5) to form a stable conductive structure.

[0016] In order to effectively improve the reliability of the motion structure of the combination of multiple flexible bodies and isolation idlers, the isolation idlers are made of self-lubricating materials and can be pre-runned with the multiple flexible bodies so that the surface has good lubrication properties, further improving its electrical conductivity and wear resistance, and can meet the stable rolling of the outer track (1), the flexible body (2), the inner track (3) and the isolation idler (5) in the stable conductive structure.
