Abstract:
A device for longitudinal measurement, comprisinga sleeve having an inner surface being at least partially threaded and an outer surface of said sleeve being at least partially threaded, said outer surface of the sleeve comprising at least one deformable tapered portion,a screw engaged in said inner surface of said sleeve, said screw being completely, continuously encircled by said sleeve when set in rotation with respect to said sleeve in such a way as to displace, said screw being displaced along a longitudinal measuring axis (x) of the device,a nut engaged on the outer surface of said sleeve and contacting said deformable tapered portion in such a way as to deform said sleeve in order to reduce an inner diameter of said sleeve to eliminate play between said screw and said sleeve,wherein said tapered portion is devoid of longitudinal slits and deformability of said sleeve, to reduce the inner diameter of the sleeve, is provided by an outer diameter of said sleeve, varied in diameter along a continuous, integral periphery of said sleeve at said outer surface of said sleeve.
