Considerations to Be Taken in the Design of Speed Increasers for Hydroturbine Service

by R. S. Pelczar,

Abstract: The paper discusses the incorporation of a speed increaser specification that is primarily functional yet one that will address the cost, reliability, efficiency, and life requirements intended for the overall configuration. The following topics are covered: adaptability of the speed increaser, designing and configuration of housings to suit powerhouse configuration, appropriate methods of rating gear elements, selection and types of bearings, designing for extreme operational conditions, design of couplings, and design of supporting lubrication systems.
