Pinion Shaft - an overview | ScienceDirect Topics

The typical IGC pinion shaft arrangement, having the impellers outboard of the seals and bearings, allows access for the application of VIGV mechanisms at the inlet of each stage (Fig. 4.5 A), if desired, and similar accessibility exists for VDVs (Fig. 4.5 B) with similar actuation mechanisms. In both cases, a single actuator rotates a control ring, which subsequently rotates each IGV or VDV ...
