Title:
ELECTRICCHYDRAULIC FOLLOW TOGGLE JOINT
Document Type and Number:
Japanese Patent JPS55126105
Kind Code:
A
Abstract:
A servomechanism in which the mutual angular position of a threaded spindle relative to a tap is adjustable by a stepper motor wherein the unit of the threaded spindle and tap is connected directly or indirectly with a hydraulic working unit, the servomechanism includes a ball bearing arranged between the spindle and the tap. Consequently, by actuating the stepper motor to which the tap is connected via a coupling, the tap being rotated and moved in axial direction relative to the spindle, thereby actuating a switching mechanism connected to the working unit by which the spindle is caused to rotate. Accordingly, the relative axial movement between the spindle and the tap is compensated and the working unit is in a different position.
