Abstract:
1. A gear train for an actuator for use in a vehicle, the gear train comprising: a drive for being rotated about a rotational axis; at least one eccentric for being driven by the drive; a ring gear; a pinion that is meshed with the ring gear and is for being driven by the eccentric so that, relative to the ring gear, the pinion carries out a rolling motion defining a point of rolling contact; and an output for rotating in response to the rolling motion of the pinion, wherein the pinion's material that is proximate the point of rolling contact is at least partially elastically deformable, the ring gear's material that is proximate the point of rolling contact is at least partially elastically deformable, or any combination thereof, so that there is surface contact at the point of rolling contact, and wherein the pinion comprises recesses configured for making the pinion's material that is proximate the point of rolling contact at least partially elastically deformable, the ring gear comprise recesses configured for making the ring gear's material that is proximate the point of rolling contact at least partially elastically deformable, or any combination thereof.
