ABSTRACT:
A length-measuring probe for gear measurement. The probe comprises a planar four-bar-guide with four hinges, each formed by plate springs; a stylus linearly guided by the bar-guide; a device for measuring the displacement of the stylus; and an additional coil spring which is adjustably arranged between the respective bars of each hinge in such a way that the plate springs are prestressed by a tensile force which decreases when the plate springs are deflected in either direction.
