Abstract

The invention provides a moment motor driving shafting module for an inner frame of an airborne photoelectric platform, belongs to the technical field of space optoelectronics, and relates to a moment motor driving shafting module. The invention aims to solve the technical problem to provide a moment motor driving shafting module for the inner frame of the airborne photoelectric platform. The technical scheme for solving the technical problem is that: the moment motor driving shafting module comprises a socket head cap screw, a motor cabinet, a moment motor, a bearing, a ring spacer, a hollow shaft, a sunk screw, a pressing ring, and a motor output shaft. The rotor of the moment motor is directly connected with the outer race of the bearing; the inner race of the bearing is connected with the hollow shaft; the hollow shaft and the stator of the moment motor are separately connected to the motor cabinet; one side of the rotor of the moment motor is provided with the motor output shaft, while the other side adopts the pressing ring to press the outer race of the bearing to eliminate a gap; and the relative concentric rotation of the rotor and the stator of the moment motor drives the frame connected with the motor output shaft and stator of the moment motor to move. The moment motor driving shafting module has a compact structure, so that the moment motor driving shafting module has the advantages of convenient installation, adjustment, detection and maintenance, and good application effect.

Description

Technical field: [0001] The invention belongs to the technical field of space optoelectronics and relates to a torque motor driving shafting module for an airborne optoelectronic platform. Background technique: [0002] The airborne optoelectronic platform is the most commonly used cutting-edge technology in modern weapon systems in the field of space optoelectronics, and is mainly used in aerial reconnaissance systems. The photoelectric imaging equipment is installed on the photoelectric platform, and the attitude of the aircraft will change at any time during flight. When the flight attitude changes, the photoelectric platform is controlled so that the optical axis of the reconnaissance camera does not deviate from the expected reconnaissance line and target, so as to achieve reconnaissance purpose and reconnaissance effects. [0003] Due to the limitation of volume and weight of the airborne optoelectronic platform, the volume and payload of the optoelectronic platform a...
