Novel high speed rotating platform based on optical fiber rotating connector

Abstract

The invention discloses a high speed rotary platform device based on a fiber rotation connecting device. The device is provided with a base which is sequentially provided with a round inductosyn, a T-shaped fine hollow main shaft and a rotary working platform. The T-shaped fine hollow main shaft is internally provided with a connecting shaft and the lower end of the connecting shaft is provided with a regular hexagon skirt. A third bearing, an electric slide ring and a second bearing are arranged between the outer side of the connecting shaft and the inner side of the T-shaped fine hollow main shaft. The upper end of the connecting shaft is provided with a connecting shaft fixing hole and a connecting shaft groove. The connecting shaft groove is internally provided with the fiber rotation connecting device. A first bearing is arranged between the outer side of the T-shaped fine hollow main shaft and the base. The base is provided with a servo motor which is connected with the T-shaped fine hollow main shaft by a gear set. The base and the rotary working platform are provided with a base photoelectric-electrolight switch module and a rotary platform photoelectric-electrolight switch module. The invention ensures the stability and precision of the system under a situation that the rotary platform rotates at high speed and has the advantages of simple system structure, small yawp inference on a signal access, large bandwidth and small signal attenuation.

technical field [0001] The invention is a novel high-speed turntable based on an optical fiber rotary connector. Background technique [0002] As a kind of complex precision electromechanical equipment, turntable is the main instrument for inertial navigator and aircraft to carry out environmental experiments. The currently commonly used turntables have low precision, large volume, and slow response speed. This is because these turntables generally transmit signals through electrical slip rings in mechanical contact.

Problems solved by technology

The currently commonly used turntables have low precision, large volume, and slow response speed. This is because these turntables generally transmit signals through electrical slip rings in mechanical contact. Due to the instability of contact resistance and electrostatic interference in the circuit at the mechanical contact High-frequency noise caused by various factors such as magnetic field interference, voltage and current mutation interference, etc. affects the acquisition and utilization of useful signals, and there are crosstalk noises between power lines and signal lines and between signal lines in multiple transmission

Elimination of interference noise requires good shielding measures and complex signal processing circuits, which increases the complexity and instability of the system

[0003] The rapid development of navigation instruments and other aircraft requires that the performance of the turntable, such as accuracy and speed, must also be greatly improved, but in the current turntable scheme, the accuracy and speed are contradictory
