Abstract

Disclosed is a harmonic wave speed reducing mechanism of an inertance stabilizing tracking platform. The harmonic wave speed reducing mechanism of the inertance stabilizing tracking platform comprises a driving structure part, a harmonic wave transmission part and a transmission output structure part, wherein the driving structure part comprises a motor rotor assembly, a motor stator assembly, a motor shaft assembly and a motor installation assembly, the harmonic wave transmission part comprises a harmonic wave generator, a harmonic wave steel wheel and a harmonic wave flexible wheel, and the transmission output structure part comprises a transmission shaft assembly, a transmission shaft sleeve assembly and a lead wire slip ring assembly. Control of the degree of freedom of rotation is achieved through a driving structure, and power support is provided to movement of the platform. A harmonic wave transmission structure is a belt of the driving structure and a transmission structure, and driving of loads of different levels can be achieved through different gear ratios. Speed reduction and twist increase of an output shaft are achieved through a transmission output structure, and servo control of an angle movement of a transmission shaft is achieved according to a programming instruction. The harmonic wave speed reducing mechanism of the inertance stabilizing tracking platform is suitable for control of the inertance stabilizing platform and has the advantages of being large in transmission ratio, good in transmission rigidity, small in size of the driving unit, light in weight, simple in structure and the like. The harmonic wave speed reducing mechanism of the inertance stabilizing tracking platform is capable of improving carrying capacity and stabilization precision of the platform and is suitable for framework driving of aerial remote sensing and target tracking.

Description

technical field [0001] The invention belongs to the technical field of aerial photoelectric imaging, and relates to a harmonic deceleration mechanism of an inertial stable tracking platform, which is suitable for power transmission drive in an aerial photoelectric imaging system using a helicopter or a light and small aircraft as a flight platform. Background technique [0002] The power transmission mechanism of the inertial stable tracking platform is one of the key equipment of the airborne earth observation platform. Its function is to support the imaging load and isolate the attitude angle movement and external disturbance of the flight carrier in three directions, so that the visual axis of the imaging load is in the inertial space. Always track and perpendicular to the local horizon, increasing imaging resolution. However, due to the limitation of the aviation application environment, the power transmission mechanism of the inertial stable tracking platform needs to h...
