<p>A form of gearing having teeth (21) with different face widths (W, W') along the tooth height and a method thereof of designing and manufacturing. Different gear tooth face widths (Figs. 2, 3, 3A, 4A, 4B, 4C, 4D) are introduced along the tooth height to alter the tooth stiffness characteristic to provide a pair of gears (12, 14) with reduced mesh stiffness variation. The use of variable face widths (Figs. 2, 3, 3A, 4A, 4B, 4C, 4D) 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.</p> |
