ABSTRACT:
A roller drive system comprises two coaxial bevelled central rollers (32,32a) each coupled to a bevelled annulus (37) by way of a respective set of bevelled rollers (34,34a) each engaging the respective central roller and the annulus. The generatrices of the engagement surfaces of the rollers in each set and the annulus intersect at a respective common point on the axis of the central rollers. Hydraulic conduits (47,49,54) are provided for communicating hydraulic pressure in common to each roller to urge each roller axially into engagement with the surfaces of the central roller and the annulus.
