| description | The invention discloses a direct-drive type disc spring energy storage and return type linear-motion quick shut-off performing mechanism. The direct-drive type disc spring energy storage and return type linear-motion quick shut-off performing mechanism comprises a power mechanism, a power switching mechanism, a transmission system and an energy storage and return mechanism, wherein the power mechanism drives the transmission system to realize motion output; the power mechanism comprises an electric drive system and a manual operation system; the power switching mechanism is used for realizingswitching between the electric drive system and the manual operation system; and the energy storage and return mechanism is used for performing shut-on and shut-off on an electric performing mechanismwhile the electric drive system is shut off. An alternating-current servo motor drives a nut to rotate under a shut-on condition, so that a lead screw moves up and down; and under a sudden power-losing condition, the motor an |
