This second edition of Design for Mechanical Power Transmission contains more than twice the content of the original monograph. New materials include the addition of a chapter on Flexible Element Drives covering flat and v belt systems, chain link drives and an overview of CVT., more design example applications with solutions in all chapters, material on selecting commercially available transmissions and added case studies of matching power source to load requirements where performance characteristics vary with speed. In addressing the classic engineering problem of matching power source outputs to driven load requirements this revision continues to emphasize: modeling and analyzing the kinematics and operational performance of mechanical transmissions, applying the resulting mathematical relationships to the solution of steady state power transmission design problems and demonstrating how power source outputs and load requirements that vary with speed can be matched to accommodate start up transients. The following list of chapters and subheadings summarize the specific topics covered. Chap. 1 Definitions - force, torque, work, power, torque / power versus powerChap. 2 Gear kinematics - involute properties simple & compound trains, reverted compound trainsChap. 3 Epicyclic gear trains - epicyclic kinematics, compound epicyclic trains, planetary gear trainsChap. 4 Gear train applications - hybrid reduction systems, continuous ratio planetary, engine speed governor, Chap. 5 Fixed ratio transmission - operational performance, restraint requirements, power loss effectsChap. 6 Variable ratio transmissions - fluid couplings, torque convertersChap. 7 Flexible element drives flat and v belt drives, chain drives, CVTsChap. 8 Matching power source to load - performance criteria, speed effects, startup time
