Problems solved by technology
[0003] In the design of aviation inertial stabilized platforms, the existing support methods for the rotary shaft system of the frame use traditional mechanical supports to realize the swing of the roll frame and the pitch frame. If a larger load is to be achieved, a larger mechanical bearing is required. , which leads to an increase in the overall size of the shafting structure and a complex structure
When the load is large, the frictional force of the mechanical bearing support will also increase accordingly, which will increase the requirements for the drive torque of the platform and increase the difficulty of control

A frame shafting support system for a three-shaft inertially stabilized platform is suitable for the support of shaftings of a rolling frame and a pitching frame of a three-shaft inertially stabilized platform; the support system of the invention adopts a double-support mechanism of a mechanical bearing and a driven magnetic bearing, which is different from a traditional mechanical bearing support mode. The support system mainly comprises a revolving shaft, a mechanical bearing, a magnetic bearing, and the like. The structure of the system has the advantages of less friction and great load bearing, when compared with a traditional mechanical support mode. The support system of the invention is suitable for the support of frame shaftings of inertially stabilized and photoelectric servo platforms for aviation remote sensing, target tracking, and the like.
Description
technical field [0001] The invention belongs to the technical field of aviation remote sensing, and relates to the support of the roll and pitch frame shaft system of a three-axis inertial stabilization platform, which is suitable for the aerial remote sensing three-axis inertial stabilization platform system with a large load and a small self-weight, and can also be used in a vehicle , shipboard, radar and target surveillance and other servo tracking and stabilization platform 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...
