Abstract: A torsional vibration damper includes a planetary gear set connected to a transmission input shaft, including a sun gear, a carrier, and a ring gear. A spring cage includes a first spring support member connected to the ring gear having multiple first spring contact members. A second spring support member is connected to the carrier and rotates with respect to the first spring support member. The second spring support member has multiple second spring contact members angularly oriented with respect to the first spring contact members. Multiple springs having opposed ends are positioned between and are compressed by rotation of the first or the second spring support member. The springs compress and extend to absorb vehicle engine vibration pulses. Each end of the springs has one of the multiple first spring contact members and or one of the multiple second spring contact members positioned proximate thereto.

Abstract: Methods for generating gear teeth of a double involute-face gear drive system, curved in their longitudinal direction in form of either shortened, normal or an extended involute curve, include methods for generating the teeth of both components. Methods for generating the teeth of a double involute pinion, shaped in form of a normal involute in their profile direction and curved in their longitudinal direction in form of an either shortened, a normal or an extended involute curve, include the use of one of the following tools (1) a face hob and (2) a conical hob. Methods for generating the teeth of a face gear curved in their longitudinal direction in form of an either shortened, a normal or an extended involute curve include the use of one of the following tools (1) a rack cutter, (2) a shaper cutter and (3) a conical hob.
