Abstract

La présente invention concerne un micromètre linéaire. Dans ce micromètre, la broche de mesure 3 est réalisée sous forme d'un tube monté mobile en translation dans le carter 1 du micromètre. Dans la broche 3, à son extrémité pénétrant dans le carter est montée glissante dans le sens de l'axe 4 de la broche, la première extrémité d'une échelle graduée 11 portant une graduation 12, dont l'autre extrémité est reliée au carter 1 du micromètre par l'intermédiaire d'un appui 13 en un seul point. La broche 3 est guidée dans le carter 1 par au moins un palier à glissement cylindrique 5, 6 et l'échelle 11 est guidée dans la broche 3 par au moins un palier cylindrique 10. La broche 3 est réglée perpendiculairement à son axe 4 à l'aide d'un mécanisme d'arrêt 8, 22, 23, 24 et son réglage de précision est assuré par un dispositif correspondant 33, 35. L'invention sert à effectuer des mesures de précision.
