[Also in Division F2] In e.g. a torsional vibration damper, resilient gear, or vehicle wheel comprising an inner hub 13 and an outer rigid ring 15 with a radiallycompressed rubber annulus 17 therebetween, the rubber annulus is made from more than one strip bent round into the annular gap. The rubber annulus may consist of two or more strips which together form a ring or of two or more strips, each of ring form, the rings lying in concentric nested relation, and preferably having the same radial thickness. In this latter arrangement one or more of the rings may be composed of two or more strips. In another arrangement, the annulus is composed of two or more strips of ring form which lie, one behind the other, in the gap between the hub 13 and the ring 15, the rings preferably having the same radial thickness. One or both of the rings may be composed of two or more strips. In a method of assembling a torsional vibration damper the strips of the compound annulus 17 are placed between rings 18, 19 which clamp the parts 13, 15 on to a bed 27, Fig. 6 (not shown), and a pressure ring 23 is then pushed axially to force the annulus into the space 16 between the parts 13, 15. In an alternative method, the parts 13, 15 are moved eccentrically to facilitate the introduction of the first and second strips, the final strip being inserted when the parts are concentric or, when the parts are moved to a third eccentric position temporarily overstressing the strips which have already been inserted. |
