Abstract:

THIS PROJECT CONCERNS A DESIGN CONCEPT FOR REDUCING THE DYNAMIC LOADS ON GEAR TEETH BY ADDING TORSIONAL FLEXIBILITY TO THE PINION/SHAFT CONNECTION. IT IS ANTICIPATED THAT THIS RESILIENT MOUNT WILL REDUCE DYNAMIC FORCES BY THE FOLLOWING MEANS. FIRST, MULTIPLE GEARS CAN BE SECURED ON A SINGLE SHAFT AND EQUALLY SHARE THE LOAD. THIS INCREASE IN FACE WIDTH ALLOWS SMALLER PITCH DIAMETERS, THIS REDUCING PITCH LINE VELOCITY AND ALSO LOWERING THE COST OF TOOTH PROFILE ACCURACY. SECOND, THE GEARSET MASS IS REDUCED BY SMALLER PITCH DIAMETERS AND THE DECOUPLING OF THE CONNECTED MASSES. THE PROJECT RESEARCH GOALS ARE TO DEVELOP A SYSTEM MODEL TO ANALYZE THE DESIGN, TO INVESTIGATE NOISE AND VIBRATION CHARACTERISTICS, AND TO PROVIDE AN ECONOMIC EVALUATION TO VERIFY THE VALUE OF THIS PROJECT TO THE GEAR INDUSTRY.
