Airborne photoelectric-platform outer frame elimination clearance torque motor driving shafting module

Abstract

An airborne photoelectric-platform outer frame elimination clearance torque motor driving shafting module belongs to a torque motor driving shafting module in an aviation optoelectronics technology field. The invention aims at providing a photoelectric-platform outer frame elimination clearance torque motor driving shafting module. In a technical scheme, a torque motor base, a torque motor stator, a torque motor shaft, a harmonic reducer input shaft, a bearing, a harmonic reducer, a torque motor rotor, an outer orientation frame, an outer high-low frame and the like are comprised. The torque motor base is fixed on the outer orientation frame. The harmonic reducer is fixed on the torque motor base. The harmonic reducer input shaft is connected with a wave generator of the harmonic reducer.The torque motor shaft is connected with the harmonic reducer input shaft. The torque motor rotor forms interference fit with the torque motor shaft. The torque motor stator is fixed on the torque motor base. The outer high-low frame is connected with a flexible gear of the harmonic reducer. By using the torque motor driving shafting module, gear transmission clearance can be eliminated and resetting is easy.

Description

technical field [0001] The invention belongs to the technical field of aviation optoelectronics and relates to a backlash-eliminating torque motor driving shafting module for an airborne optoelectronic platform. Background technique [0002] The airborne optoelectronic platform is a kind of reconnaissance equipment in the field of aviation optoelectronics. It has the characteristics of flexible maneuverability, real-time accuracy, and strong pertinence. It is mainly used in aerial reconnaissance systems. The airborne optoelectronic platform is usually equipped with a variety of optoelectronic mission loads such as visible light and infrared. When performing tasks, no matter how the flight attitude and route of the carrier aircraft change, the optoelectronic platform is controlled so that the visual axis of the optoelectronic task load does not deviate from the expected detection. Lines and targets, so as to achieve the intended reconnaissance purpose and reconnaissance effec...
