Three-axis simulation flight simulator executing mechanism

Abstract

The invention discloses a three-axis simulation flight simulator executing mechanism. The mechanism includes a roll platform, a pitch platform, a yaw platform, and a base platform. The roll platform includes a front cabin, a rear cabin, a roll motor, a roll reducer, a roll sprocket pair minor sprocket, a roll cylindrical bore self-aligning roller bearing, and a large-diameter rubber roller pivotalbearing inner ring. The pitch platform includes a pivotal bearing outer ring, a U-shaped frame, a roll sprocket pair large sprocket, a roll bearing seat, a pitch sprocket pair large sprocket, a pitchright shaft, a pitch cylindrical bore self-aligning roller bearing, and a pitch left shaft. The yaw platform includes a U-shaped bracket, a pitch bearing seat, a pitch motor, a pitch reducer, a pitchsprocket pair minor sprocket and a yaw bearing seat. The base platform includes a base, a base bracket, a large-diameter pivotal bearing, a yaw motor, a yaw reducer, an open internal gear meshing pair small gear, and support feet. The mechanism of the invention can simulate that a single person operates an aircraft to perform three degrees of freedom of roll, pitch and yaw movements to realize asimulated flight function.

Description

technical field [0001] The invention relates to the technical field of mechanical structure and transmission, in particular to an actuator for a three-axis simulation flight simulator. Background technique [0002] The actuator of the three-axis simulation flight simulator is the main component of the three-axis simulation flight simulator. It combines relevant flight software and numerical control drive technology to simulate a single-person control of the aircraft and perform three-degree-of-freedom movements of roll, pitch, and yaw. Realize the flight simulation function. [0003] At present, most of the existing three-axis simulation flight simulators in China are rigid structures. The rolling part adopts large-diameter slewing bearings, and the roll and pitch drives all adopt structural forms such as gear reduction transmission mechanisms, so that the actuators of the three-axis simulation flight simulator It is bulky, heavy in structure, loud in operation noise, and h...

[0003] At present, most of the existing three-axis simulation flight simulators in China are rigid structures. The rolling part adopts large-diameter slewing bearings, and the roll and pitch drives all adopt structural forms such as gear reduction transmission mechanisms, so that the actuators of the three-axis simulation flight simulator Huge volume, heavy structure weight, loud operation noise, high power consumption, and relatively high requirements for the manufacturing and assembly precision of structural parts, which increases the manufacturing cost
