The method of the invention defines the steps to be practiced in loosening tightly-joined elements, i.e., loosening a rotor which has been shrunk onto a shaft, for example, in order that the relative positionings of such rotor and shaft may be altered. With the one element having a bore tightly fitted about the surface of the other element, the method teaches the introduction of fluid under pressure between the bore and the surface, whereby the latter is sufficiently expanded to accomplish the loosening. The invention further sets forth tightly-joined elements especially configured to enable a practice of the method. Hence, one of the elements has a conduit formed therein for introducing fluid under pressure to the interface formed by the surfaces of the elements which are in fast engagement. |
