It has been hard for me to escape the imprint of my early, strong, but scattered trains of thought. There was, at the beginning, little to go by; and I saw no clear way to go. This book is accordingly filled with internal tensions that are not, as yet, fully annealed. Subsequent writers may re-present the work, explaining it in a simpler way. Others may simply invert it. I mean by this that, by writing it backwards, from its found ends {practical machinable teeth) to its tentative beginnings (dimly perceived geometrical notions), one might conceivably write a manual, not on how to understand these kinds of gears, but on how to make them. Indeed a manual will need to be written. If this gearing is to be further investigated, evaluated and checked for applicability, prototypes will need to be made. I wish to say again however that my somewhat convoluted way of presenting these early ideas has been inevitable. It has simply not been possible to present a tidy set of explanations and rules without exploring first (and in a somewhat backwards-going direction) the complexities of the kinematic geometry. There remains, now in this book, a putting together of primitive geometric intuition, computer aided exploration of certain areas, geometric explanations of the discovered phenomena, and a loose sprinkling of a relevant algebra cementing the parts together.

Computational kinematics is an enthralling area of science with a rich spectrum of problems at the junction of mechanics, robotics, computer science, mathematics, and computer graphics. The present book collects up-to-date methods as presented during the Fifth International Workshop on Computational Kinematics (CK2009) held at the University of Duisburg-Essen, Germany. The covered topics include design and optimization of cable-driven robots, analysis of parallel manipulators, motion planning, numerical methods for mechanism calibration and optimization, geometric approaches to mechanism analysis and design, synthesis of mechanisms, kinematical issues in biomechanics, balancing and construction of novel mechanical devices, detection and treatment of singularities, as well as computational methods for gear design. The results should be of interest for practicing and research engineers as well as Ph.D. students from the fields of mechanical and electrical engineering, computer science, and computer graphics.

The first book of its kind, Theory of Gearing: Kinematics, Geometry, and Synthesis systematically develops a scientific theory of gearing that makes it possible to synthesize novel gears with the desired performance. Written by a leading gearing expert who holds more than 200 patents, it presents a modern methodology for gear design. The proposed theory is based on a key postulate: all the design parameters for an optimal gear pair for a particular application can be derived from (a) a given configuration of the rotation vectors of the driving and driven shafts and (b) the power transmitted by the gear pair. This allows engineers to synthesize the desired gear pairs with only the following input information: The rotation and torque on the driving shaft The configuration of the driven shaft in relation to the driving shaft The desired rotation and torque of the driven shaft Beginning with the fundamentals, the book reconsiders the basic theory of kinematics and geometry of gears to provide a sound basis for the evaluation and development of future designs. It then examines ideal and real gearing for parallel-axis, intersected-axis, and crossed-axis gearing. The book addresses how to minimize vibration and noise in gears, discusses aspects of implementing the theory of gearing, and analyzes principal features of power transmission and the loading of gear teeth. More than 500 figures clearly illustrate the principles. This is an invaluable resource for engineers and researchers who work in gear design, gear production, and the application of gears as well as for students in mechanical and manufacturing engineering. Covering all known gear designs, this book offers an analytical solution to the problem of designing optimal gear pairs for any given application. It also encourages researchers to further develop the theory of gearing.

This is the first part of a series of books whose aim is to collect contributed papers describing the work of famous persons in MMS (Mechanism and Machine Science). The current work treats mainly technical developments in the historical evolution of the fields that today are grouped in MMS. The emphasis is on biographical notes describing the efforts and experiences of people who have contributed to technical achievements.

Building on the first edition published in 1995 this new edition ofKinematic Geometry of Gearing has been extensively revised andupdated with new and original material. This includes themethodology for general tooth forms, radius of torsure’,cylinder of osculation, and cylindroid of torsure; the author hasalso completely reworked the ‘3 laws of gearing’, thefirst law re-written to better parallel the existing ‘Law ofGearing” as pioneered by Leonard Euler, expanded fromEuler’s original law to encompass non-circular gears andhypoid gears, the 2nd law of gearing describing a unique relationbetween gear sizes, and the 3rd law completely reworked from itsoriginal form to uniquely describe a limiting condition oncurvature between gear teeth, with new relations for gearefficiency are presented based on the kinematics of general toothedwheels in mesh. There is also a completely new chapter ongear vibration load factor and impact. Progressing from the fundamentals of geometry to construction ofgear geometry and application, Kinematic Geometry of Gearingpresents a generalized approach for the integrated design andmanufacture of gear pairs, cams and all other types oftoothed/motion/force transmission mechanisms using computerimplementation based on algebraic geometry.

This new edition provides extensive information to designers on various aspects of gears and gearing systems. Very comprehensive in its coverage, the handbook contains enough tables, illustrative examples and diagrams to enable designers arrive at quick solutions for their problems. The handbook is based on ISO specifications and is a unique blend of practical as well as the theoretical aspects of gear designs. The new edition includes more on spiral bevel gears, arcoid gears, klingelnberg and gleason systems and gear tooth checking.
