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 lead screw pair is stuck or jammed. Meanwhile, a standby bearing lead screw pair is started to synchronously complete mechanical fault self-recovery.
