A compact coupling reaming apparatus and method for reaming coupling bolt holes of a rotor coupling. The apparatus includes a fixture plate for mounting the apparatus to the face of the coupling via a plurality of the coupling bolt holes. The apparatus also includes a drill axially slidably, radially slidably, and axially rotatably mounted to the fixture plate. During the reaming process, the drill is first aligned with the center of a first coupling bolt hole, the drill having a fixed distance from an axis of the rotor after being aligned with the center of the first coupling bolt hole. After reaming the first coupling bolt hole, the drill is aligned with a center of the holes and all other coupling bolt holes to be reamed by axially rotating the drill to the center of the second coupling bolt hole while maintaining the fixed distance of the drill from the axis of the rotor.

Coupling reaming apparatus and method

A method of installing a seal having a sealing surface in a defined operating position in a rotating machine composed of a stationary part which carries the seal and a rotary part mounted to rotate about an axis of rotation and having a cylindrical surface located to rotate adjacent, and in close proximity, to the sealing surface, which method includes: installing the seal on the stationary part in a position corresponding to the defined operating position so that the seal is immovable relative to the stationary part; machining the sealing surface to a desired final dimension by mounting a machine tool to rotate about the axis of rotation and rotating the tool about that axis; withdrawing the tool; and modifying the installation of the seal so that the seal is supported in the defined operating position so as to be resiliently movable relative to the stationary part.
