High-accuracy and heavy-load bearing support system for inertially stabilized platform

Abstract

Disclosed is a high-accuracy and heavy-load bearing support system for an inertially stabilized platform. The bearing support system comprises a rotor inner ring, rolling elements, a first fastening screw, a bearing drive bracket, a pitching frame, a second fastening screw, an adjusting washer, a stator outer ring, a third fastening screw, a seal cover and an upper seal ring. The rotor inner ring, the rolling elements and the stator outer ring form a rotation base body and installed on the pitching frame integrally, and accordingly, + / -360-degree rotation of the rotor inner ring relative to the stator outer ring can be achieved. During operation, the rotor inner ring is connected with an external camera to serve as a bearing frame of the inertially stabilized platform to drive the external camera to adjust bearing attitudes. According to the high-accuracy and heavy-load bearing support system for the inertially stabilized platform, technologies that steel rolling tracks are embedded into hard aluminum substrates, ceramic ball rolling elements are filled, and the like are utilized, so that the bearing support and the stabilized platform system are compatible and integrated, and the structure height is compact. The system has the advantages of high accuracy, heavy load, small size, light weight, corrosion resistance and the like, and is applicable to aerial remote sensing system and other inertially stabilized and tracking surveillance systems.

Description

technical field [0001] The invention belongs to the technical field of aerial remote sensing, and relates to an azimuth support system for a high-precision, large-load inertial stabilization platform, which is suitable for an aerial remote sensing three-axis inertial stabilization platform with requirements such as large load, high precision, light weight, and small volume, and is also applicable to Other types of inertial stabilization and tracking and targeting monitoring systems. Background technique [0002] The aerial remote sensing three-axis inertial stabilization platform is one of the key equipment for airborne earth observation. 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 can always track in the inertial space. And perpendicular to the local level, improving imaging resolution. However, due to the limitation of the...
