Abstract
THE object of this volume is to present in a simple manner the general scientific principles which underlie the subject, and to give particulars of the most approved methods of solving problems connected with various forms of gears. Spur, bevel, worm, spiral and helical gears are included, and methods of cutting these gears are explained and illustrated by photographs. The calculations given are of the simplest possible character and should present no difficulty to anyone who knows ordinary arithmetic. Extensive tables are given which will simplify the process of finding the pitch, diameter, and outside diameter of wheels having a given circular pitch. A considerable amount of space is taken up with blacked drawings showing the comparative sizes of teeth having progressive diametral and circular pitches. The latter might have been omitted, and space found for a discussion of the new problems introduced by the applications of helical wheels in marine turbine speedreduction gears. The desire of the author to keep the matter treated within the limits of simplicity prescribed by the knowledge of the readers he has in view no doubt accounts for the many omissions in an otherwise useful volume.
