Title:
ELECTROMECHANICAL ACTUATOR AND METHOD FOR FORCED UNLOCKING OF FUZZY JAMMING FAULT OF TRANSMISSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/284102
Kind Code:
A1
Abstract:
An electromechanical actuator for forced unlocking of a fuzzy jamming fault of a transmission mechanism comprises a bidirectional electromagnetic braking assembly, a circumferential rotating housing assembly, an axial spline bearing assembly, an LVDT linear displacement sensor assembly, a potentiometer linear displacement sensor assembly, and an electromechanical actuator assembly. The axial spline bearing assembly is mounted inside the circumferential rotating housing assembly for a reciprocating linear motion, and the axial spline bearing assembly is connected to an output rotating shaft of the electromechanical actuator assembly to form a spiral transmission pair; the bidirectional electromagnetic braking assembly is actively energized to generate radial and axial attraction forces, so that the circumferential rotating housing assembly is disengaged from a fixed connection with the electromechanical actuator assembly to rotate, thereby forcing the connection between the axial spline bearing assembly and the electromechanical actuator assembly to fail, and forcibly releasing a transmission jamming or stagnation fault of a rotor screw rod (9) in the electromechanical actuator assembly and the axial spline bearing assembly; and when two linear displacement sensors arrive at a switching position instantaneously, a recovery control signal is sent to the bidirectional electromagnetic braking assembly to complete the recovery of a mechanical transmission function.
