ABSTRACT:
The present invention relates to a process for shrinking a ring to be shrunk, placed around an object to be clamped on a cylindrical support and behind an axial obstacle connected to said support. The process comprises the following steps of: a) fitting a shrinking tool around the support, over the axial obstacle, until its jaws in expanded position are disposed in the radial plane of the ring to be shrunk, b) positioning in the jaws, by the rear of the axial obstacle, a spacer presenting a central opening adapted to the ring to be shrunk, and c) finally, tightening the shrinking tool to bring the jaws and the spacer that they contain in their retracted positions.
