PURPOSE: A jackscrew device is provided to drive a high power gearbox with a relatively small low-torque motor and to endure the drive load of a nut exceeding the steady stop torque of the motor. CONSTITUTION: A jackscrew device(10) for converting a reciprocal rotational motion into a reciprocal linear motion is composed of a nut(12) threaded on a screw(14) for reciprocal translational motion and against rotational motion, a motor drive-connected to the screw and the motor reversibly rotating the screw for a longitudinal screw axis(18) to drive the nut through the reciprocal translational motion, and a lost motion drive linkage connected between the motor and the nut. The lost motion drive linkage allows a lost rotational motion between the motor and the nut for the motor to accelerate before bearing the load of the rotation of the screw and the driving of the nut translational motion. 왕복 회전 운동을 왕복 선형 운동으로 변환시키기 위한 잭 스크루 장치가 개시된다. 본 발명의 잭 스크루 장치는 왕복 병진 운동에 적합하고 회전 운동이 부적합하게 스크루에 나사 결합되는 너트를 구비한다. 스크루에 연결된 모터가 종방향 스크루축을 중심으로 스크루를 가역 회전시켜 왕복 병진 운동을 통해 너트를 구동시킨다. 헛돌기 회전 이동에 따라 모터는 스크루를 회전시키고 너트의 병진 운동을 구동시키는 부하가 걸리기 전에 가속할 수 있다.
