Abstract

The invention discloses a stable platform with a differential structure based on flexible cable transmission. The stable platform comprises a platform body, a driving unit and a differential mechanism, wherein the differential mechanism comprises an azimuth axle, a pitching axle and a flexible cable component; the azimuth axle and the pitching axle are driven by the flexible cable component; the azimuth axle is rotationally arranged on the platform body; the pitching axle is rotationally arranged on the azimuth axle and is orthographic to the axis of the azimuth axle; and the output end of the driving unit is in driving connection with the azimuth axle. According to the stable platform disclosed by the invention, the limitation that a load weight ratio of an existing integral stable platform is difficult to increase can be broken, and high torque is outputted by a small motor; besides, higher transmission precision is ensured; the contradiction between precision requirements of the platform and transmission properties of the mechanism is effectively coordinated; the conflict between the compact design of the platform and improvement on adaptability is overcome; and the stable platform has the characteristics of high loading capacity, high adaptability, light weight, high precision and compact structure.

Description

technical field [0001] The invention relates to a two-degree-of-freedom stable platform for isolating carrier disturbance and stabilizing inertial pointing, and specifically relates to a differential structure stable platform based on flexible cable transmission. The type of load is suitable for but not limited to photoelectric detectors, and can be used for Various precision pointing mechanisms such as aircraft reconnaissance pods, ship-borne photoelectric tracking systems, and vehicle-mounted antenna systems. Background technique [0002] The stable platform is a precision pointing mechanism that compensates the carrier disturbance through multi-axis motion under the condition of the moving carrier, so as to keep the load pointing inertia stable and further realize other functions such as tracking the target. At present, in order to ensure high stability accuracy, the two-axis and two-frame integral stabilized platforms at home and abroad are often directly driven by torqu...
