Good tip.. Generally in a machine train with gearbox in between motor and driven machine, gearbox will be taken as the static machine and the motor, driven machine will be considered as movable machines. But it is not always possible to keep gearbox as a static machine. Some times base-bound and bolt-bound conditions for optimizing alignment correction, gearbox needs also be considered as movable machine.

Rao, it is true that in some instances, the gearbox is the stationary machine. I would say that for alignment purposes, this is an ideal scenario. With the gearbox being the stationary machine, the alignment becomes a bit easier because one now only needs to worry about two single coupling alignments, instead of one alignment of two couplings.
