Tensioning device for fixing inner ring of friction bearing to shaft has journals used as clamping elements

摘要

The tensioning device (2) consists of a sleeve (9) and clamping elements in the shape of journals (10) radial guided in a cage (11). The shaft (3) is inserted through a bore (12) into the sleeve. One end of the clamping sleeve is equipped with radial arranged grooves (13) to facilitate the rotation of the sleeve in relation to the inner ring (4). One of the segments (14) formed by the grooves is folded over and locks the shaft inside the sleeve.
