CA 2268054

A mounting device (10, 10') for coaxially anchoring a machine element (11, 11') upon a rotary shaft (12, 12'). The device fits between the interior bore (13, 13') of the machine element and the cylindrical surface of the shaft and is effective to position the element at any desired position longitudinally of the shaft and at any angular position circumferentially of the shaft. The device has inner (20, 20') and outer (50, 50') sleeves, the mating surfaces of which are similarly tapered so that relative axial displacement of the sleeves effects expansion and contraction of the interior bore (13, 13') and external surface of the combined elements. Rotation of a threaded nut (23, 45') at one end of the device effects the relative axial displacement of the inner and outer sleeves to afford expansion and contraction of the outer sleeve (50, 50').

L'invention concerne un dispositif (10, 10') de fixation destiné à ancrer de manière coaxiale un élément (11, 11') de machine sur une tige (12, 12') rotative. Le dispositif est ajusté entre l'alésage (13, 13') intérieur de l'élément de machine et la surface cylindrique de la tige et sert à placer l'élément dans n'importe qu'elle position longitudinale voulue par rapport à la tige et dans n'importe qu'elle position angulaire autour de la tige. Le dispositif comporte des manchons intérieurs (20, 20') et extérieurs (50, 50'), dont les surfaces de contact sont effilées de manière similaire de sorte qu'un déplacement axial relatif des manchons entraîne une expansion et une contraction de l'alésage (13, 13') intérieur et de la surface extérieure des éléments combinés. La rotation d'un écrou (23, 45') fileté situé à une extrémité entraîne le déplacement axial relatif des manchons intérieurs et extérieurs pour permettre une expansion et une contraction du manchon extérieur (50, 50').
