Part of the "Machinery's Reference Series", this volume contains a complete guide to bevel gearing written by Ralph E. Flanders. Bevel gears refer to types of gears where the axes of the two shafts intersect each other and the tooth-bearing sides of the gears are conically shaped. Bevel gears are usually mounted on shafts that are 90 degrees apart, but they can also be made to work at other angles as well. This vintage book contains a wealth of useful information on the subject, and is not to be missed by those with a practical interest in tradition methods of bevel gearing. Ralph Edward Flanders (1880 - 1970) was an American industrialist, mechanical engineer, and Republican U.S. Senator from the state of Vermont. He served as the president of the Boston Federal Reserve Bank for two years before being elected U.S. Senator from Vermont. Contents include: "Bevel Gear Rules and Formulas", "Examples of Bevel Gear Calculations", "Systems of Tooth Outlines Used for Bevel Gearing", "Strength and Durability of Bevel Gears", "Design of Bevel Gearing", "Machines for Cutting Bevel Gear Teeth", and "Cutting the Teeth of Bevel Gears". Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
