Abstract
The clamping arrangement has a pair of elements which are provided with mating conical surfaces in the self locking range. The elements can be axially displaced relative to each other by axial clamping screws for clamping purposes. Auxiliary rings are provided between the elements and have through bores for the clamping screws. With the clamping screws removed, the auxiliary rings can be turned to align a tapped bore in one ring and an abutment surface in the other ring with a clamping screw so that this screw can be used for separating the clamped elements from each other.
Claims8
A clamping arrangement for clamping a pair of concentrically disposed parts together, said arrangement comprising
- an inner element having a tapered conical surface;
- an outer element having a tapered conical surface for locking against said conical surface of said inner element;
- a plurality of clamping screws disposed in an annular array, each said screw passing through one of said elements into threaded engagement with the other of said elements to clamp said elements together;
- a first rotatable ring disposed between said elements with a plurality of through bores and a plurality of abutment surfaces disposed in alternating manner, each said bore being disposed coaxially of a respective screw for passage of said screws therethrough;
- and
- a second rotatable ring disposed between said first ring and said one element, said second ring having a plurality of through bores disposed on a pitch circle and a plurality of tapped bores disposed on said pitch circle in alternating manner with said through bores, each said through bore of said second ring being disposed coaxially of a threaded screw for passage of said screw therethrough whereby with said screws withdrawn from said other element and said rings, said rings can be rotated to align said screws with said tapped bores and said abutment surfaces to permit unclamping of said elements.
In combination
- a first part;
- a second part concentrically mounted on said first part;
- an inner element between said parts and having a tapered conical surface;
- an outer element between said parts and having a tapered conical surface for locking against said conical surface of said inner element;
- a plurality of clamping screws disposed in an annular array, each said screw passing through one of said elements into threaded engagement with the other of said elements to clamp said elements together;
- a first rotatable ring disposed between said elements with a plurality of through bores and a plurality of abutment surfaces disposed in alternating manner, each said bore being disposed coaxially of a respective screw for passage of said screw therethrough;
- and
- a second rotatable ring disposed between said first ring and said one element, said second ring having a plurality of through bores disposed on a pitch circle and a plurality of tapped bores disposed on said pitch circle in alternating manner with said through bores, each said through bore of said second ring being disposed coaxially of a threaded screw for passage of said screw therethrough.
