Abstract:
In a device for locking to a component rotatable about an axis; said device comprising collar means having an end wall with a bore defining a surface for confronting an outer surface of the rotatable component and a region extending axially from the end wall, a ring for disposing between the axial region of the collar means and the component, the ring having a first inner surface for confronting the outer surface of the component and a second outer surface which is inclined relative to the axis of rotation to converge with respect to the axis of rotation in a direction away from the end wall and at least two screw-threaded elements received in screw-threaded bores extending through the axial region of the collar means and spaced apart relative to the rotational axis other than at 180.degree., the screw-threaded elements being adjustable to tighten and contact the second inclined surface of the ring or to be released from such contact; wherein when the screw-threaded elements are released from such contact the collar means is free to rotate about the axis relative to the ring and when the screw-threaded elements are tightened to bear into or against the second outer surface of the ring radial displacement of the collar means and the ring relative to the axis then occurs thereby to cause the bore surface of the collar means and the first surface of the ring to act as contact surfaces with respect to the outer surface of the component and exert clamping force on the component at diametrically opposed zones; the improvement wherein the threaded bores are disposed in positions non-radial relative to the rotational axis.
