Description

technical field [0001] The invention relates to a device for simulating modular rolling conductive rotary motion in a vacuum environment, which is used for simulating the relative rotation of the "conductive rotary joint", a key component of power transmission of a space super-power and expandable power spacecraft, during the electrification process. Background technique [0002] Conductive rotary joints are essential electromechanical components for satellites, spacecraft and large-scale space facilities in space. They are responsible for the orientation of solar panels to the sun and the transmission of collected energy to the body of satellite spacecraft. The power transmission level of traditional conductive rotary joints is within 10kW. With the substantial increase in space transmission power requirements, the power transmission requirements of large spacecraft and ultra-large space facilities can reach 100kW, or even 1MW. In order to reduce power loss, it has become a...

Problems solved by technology

When this confluence ring device transmits power and information, it has to go through two rolling transmission processes of the rolling plate and the rolling ring. Due to the addition of a rolling transmission process, the fluctuation resistance will be increased, the manufacturing cost will be increased, and the reliability of the rolling ring will be reduced. sex
