Abstract
An adjusting device including a CVT planetary roller transmission having two axially-spaced sun wheels that are rotatable about a common axis of rotation and at different speeds of rotation. Planet wheels contact and ride against peripheral surfaces of each of the sun wheels, and an axially displaceable ring wheel lies radially outwardly of the sun wheels and engages a peripheral groove formed in the sun wheels. When the ring wheel is axially displaced relative to the sun wheels the axes of rotation of the planet wheels tilt relative to the sun wheel axis resulting in a difference in the rotational speed of the sun wheels changes. The device can be employed as an adjusting device for adjusting the rotational speed of connected units, and also as a drive line component having a variable transmission ratio and situated in a power train of a motor vehicle.
