Abstract
A form of gearing having teeth with different face widths along the tooth height and a method thereof of designing and manufacturing. Different gear tooth face widths are introduced along the tooth height to alter the tooth stiffness characteristic to provide a pair of gears with reduced mesh stiffness variation. The use of variable face widths along the tooth height changes both the geometric properties of the tooth and the load distribution/concentration to reduce the self-excited component of dynamic load, in effect reducing gear noise and increasing power density.
