ABSTRACT:
In a driving mechanism of the kind having a drive part and a driven part with a shear-type coupling therebetween, the drive and driven parts have respective cylindrical surfaces which are spaced apart from, and substantially coaxial with, one another to define an annular space centered on the rotational axis of the parts. A fluid is disposed in the annular space to provide, at least in part, the said shear-type fluid coupling, and the spaced cylindrical surfaces together with the fluid therebetween constitute the sole bearing for the drive part. The fluid may contain an anti-creep additive. One of the said cylindrical surfaces, preferably the inner circumferential surface, may be constituted, at least in part, by a porous member impregnated with a shear-type fluid.
