Abstract

A device for isolating fluctuations in drive torque of a rotary drive shaft to a pulley comprising first 2 and second 3 members for connection to drive shaft and driven member respectively and an annular, externally hexagonal resilient member 22 interposed between the first and second members which has apertures 27 each containing a sleeve 28, wherein a first aperture receives a projection 30 connected to the first member and a second of said apertures receives a projection 31 connected to the second member. In use the resilient member is compressed between the projections which may be studs or integral with the respective member formed by cutting and bending (150, 151 Fig. 3). The first member has an axial ring 7 carrying an inertia member 16 via an elastomeric layer 19 and there are PTFE or nylon tape bearings 11, 18, 20 between the parts.
