Author: Earle Buckingham Publisher: ISBN: Category : Technology & Engineering Languages : en Pages : 472
Book Description
Discusses the nature of the action involved in screw gearing, the attendant contact conditions and how all-recess action design concepts can improve load-carrying and life capacity. Provides observations based on the authors' experience and worked-out step-by-step examples that will sharpen the reader's judgement of what to do and what not to do in spiral and worm gear design. Contains the formulas, diagrams, and methods needed to solve bearing load problems. Discusses in detail how graphical methods are used to determine contact conditions on spiral drives and worm drives that are based on the use of both the screw helicoid thread form and the involute helicoid form. Shows how beam strength, limiting loads for wear, and dynamic loads on spiral and worm gears are evaluated.

Book Description
The book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as: straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. Includes fully-developed exercises to draw the reader's attention to the problems that are of interest to the designer, as well as to clarify the calculation procedure Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

Book Description
Excerpt from Spiral and Worm Gearing: A Treatise on the Principles, Dimensions, Calculation and Design of Spiral and Worm Gearing, Together With Chapters on the Methods of Cutting the Teeth in These Types of Gears The manner in which machinery's book, Spur and Bevel Gearing, has been received by the mechanical world has prompted the compilation and publication of a companion book on Spiral and Worm Gearing. This subject has often been presented in so theoretical a manner that many have assumed it to be very difficult to master. It is possible, however, to present the principles of design and calculation of spiral and worm gearing in such a way that they can be readily under stood without resorting to a highly theoretical treatment; and in preparing this book, the first consideration on the part of the editor has therefore been to treat the subject in such'a way as to meet the practical requirementsof the machine-building trade. As a result, in this book, as well as in the companion book, Spur and Bevel Gearing, mere theory and academic discus sions have been avoided. The rules, formulas and instruc tions given are illustrated with engravings whenever necessary, and numerous examples are given to show their application to problems met with in machine design. Theoretical considera tions, however, have not been neglected in cases where they have been found necessary to fully explain a practical process, and this book is, therefore, a treatise on both the theory and practice of spiral and worm gearing along such lines as will make it especially useful to practical men.
