A frustoconical ring body comprises at least one and preferably a pile of tough and elastic, frustoconical ring elements (11) each having a central opening (11a) for slidably accepting therethrough a first cylindrical member (1) and an outer edge (11e) adapted for engagement with a second member (4). The ring element (Figs. 2a,2b, not shown) has a plurality of outer slits (11f) extending radially inwardly from the outer edge and a plurality of inner slits (11d) extending radially outwardly from the central opening. An inclination adjusting member (6) is displaceable along one of the (1,4) members so as to maintain a bearing contact with the ring body and to change a frustoconical angle, thereby regulating the state of engagement of the ring body with the first and second members. The assembly may be used either as a bearing; a brake; to mount a bearing race; or as a gear, in which case the outer edge of the ring body has gear teeth which mesh with teeth on the second member. |
