Optimal gear design method

Failure and pitting of teeth of gear affects transmission error. So, aim of this study was to define optimal tooth modifications introduced by performing static contact and deformation analysis, while trying to design spur gears to resist failure and pitting of the teeth. Behaviour of unusual contact between flywheel ring gear and starter motor pinion was analysed and optimized root fillet was introduced in spur gear.

In this paper, a method for optimal design of structure parameters of gears in order to reduce the vibration of the car gearbox during the work process is presented. The model of a pair of interlocking gears was simplified by the two pairs of useful volume and elastic springs. From this model, it is established the formulas in order to determine elastic stiffness of gear, synthetic hardness a pair of interlocking gears, useful volume of gears, private frequency and the speed limit of the gear.

This research project was motivated by the possibility of using fracture mechanics to assist in optimizing gear design. The primary goal is to develop a state-of-the-art capability for modeling three-dimensional crack propagation in gears using boundary element method, finite element method, and fracture mechanics. It is being conducted by a grant between Cornell University and the NASA-Glenn Research Center (formerly known as Lewis Research Center).
