Title:
ULTRA-SHORT ELECTROMECHANICAL SERVO MECHANISM FOR MECHANICAL FAULT SELF-RECOVERY
Document Type and Number:
WIPO Patent Application WO/2024/060364
Kind Code:
A1
Abstract:
An ultra-short electromechanical servo mechanism for mechanical fault self-recovery. Two sets of lead screw transmission components having the same lead parameters and bearing capacity are redundantly and coaxially arranged, and are powered by a single servo motor set. A lead screw roll limiting electromagnetic clutch and a nut roll limiting electromagnetic clutch are used for realizing fault isolation when a primary bearing lead screw pair is stuck or jammed. Meanwhile, a standby bearing lead screw pair is started to synchronously complete mechanical fault self-recovery. Therefore, miniaturization and integration are aimed while the performance of the machine is not compromised. The null length is subjected to ultra-short design to improve the power density of a redundant EMA.
