The alignment of high speed gears

摘要

This paper reviews the necessity for detailed specification, design and manufacture to achieve required performance in service. The precise definition of duty rating and a thorough understanding of the environmental conditions, whether it is in a marine or industrial application, is required to predict reliable performance of a gearbox through its service life. A case study relating to complex marine gears and other general practice is presented to review the techniques used by Allen Gears to design and develop a gearbox that integrates with the requirements of the whole machinery installation. Allen Gears has considerable experience in the design of a variety of industrial and marine gears (Ref. 1, 2). The requirements of different types of installations are reviewed to study the implications on gear alignment. Particular types of gearboxes have been developed in recent years to achieve more accurate alignment while also reducing the size and cost of a drive system.
