<p>Hydraulically actuatable friction clamp coupling of the type which can be used for clamp connecting a hollow shaft (2) to a drive shaft (3) and which comprises a shape deformable inner ring (4) which is adapted to engage the sleeve or the hollow shaft (2), and which, at the outer surface thereof, is formed as a double, counter directed screw having two screw portions (8, 9) which meet substantially at the longitudinal centre of the inner ring (4), and the screw flange sides of which have the shape of saw tooth formed cone surfaces (10) as seen in an axial cross section, and two outer rings (5, 6) which, at the inner race thereof, are formed with screw like cone surfaces (11) which are saw tooth shaped in a cross section view, and which match the cone surfaces (10) of the inner ring (4), and in which the two outer rings (5, 6) in form, in common, an intermediate, sealed pressure chamber (14) which is filled with a hydraulic pressure medium adapted to be pressurized from an internal or external source of pressure (7), whereby the outer rings (5, 6) are being pressed apart and the inner ring (4) is being compressed thereby clamping the hollow shaft (2) onto the drive shaft (3). Means are provided for mechanically blocking the outer rings with full clamp action in their moved-apart conditions.</p> |
