Abstract
A torque transmitting gear includes a steel toothed annular flange having gear teeth defined on a periphery of the steel toothed annular flange. A steel hub is coaxially aligned with the steel toothed annular flange. A web is formed from a web material having a density less than or equal to 3.0 grams per cubic centimeter. The web is fixedly attached to the toothed annular flange and to the hub for rotation together with the toothed annular flange and the hub. The gear is to operatively transmit a torque of at least 500 Newton Meters for at least 6 million revolutions of the gear. An overall mass of the gear is less than two-thirds of an overall mass of a same-sized all steel gear having a solid steel web with a solid steel web thickness at least one-third of a face width of the toothed annular flange.
