    摘要： A linear actuator (1), comprising a threaded spindle (10) with a longitudinal extension along a longitudinal axis (X), the spindle (10) having a right hand thread (11) and a left hand thread (12), both threads provided over a common longitudinal length of the spindle, the spindle (10) being adapted to be rotated by a driving device (60). The linear actuator further comprises a first nut member (20) provided with a right hand thread (21) and a second nut member (30) provided with a left hand thread (31). The first and the second nut members (20, 30) are in threaded connection with the spindle (10) in such a way that rotation of the spindle provides opposite linear movement of the nut members (20, 30) relative to each other along the longitudinal axis (X). Thereby, a linear actuator is provided with three parts that all move linearly relative to each other during rotation of the spindle.

    摘要： A twin screw spur gear drive in the form of an electromotive linear drive, useful for furniture in the field of hospital and nursing care, includes a housing for attachment of a flanged tube, and a screw drive having at least two spur wheels and a screw, which is wedged onto a journal of an electric motor and engaging the spur wheels, for operating a spindle. A drive nut is placed in threaded engagement with the spindle and secured against rotation. The drive nut carries a lifting tube which is connected to a component to be operated and moves back and forth as the spindle rotates and the nut is advanced along the spindle. In order to protect the twin screw drive from ingress of contaminants such as cleaning liquid, seals are provided for sealing at least some of the abutting surfaces between the housing and adjoining components.

    摘要： This invention relates to a device for producing precise linear movement in response to a rotary input. More particularily, the invention comprises two threaded shafts respectively having threads of different pitches, one of the shafts being secured against both axial and rotation movements and the other shaft being connected to an actuated device in such fashion that only axial movements of the other shaft is permitted, and cylindrical member rotated by a power source connected by separate threaded sections to both said threaded shafts, whereby rotation of the cylindrical member results in a low speed movement of the actuated member at a rate proportional to the difference in the reciprocals of the thread pitches.
