Abstract: A friction ring-type transmission includes two roller bodies which are arranged at a distance from each other about a gap, which correspond to each other via the friction ring and which rotate (5) on axial roller body axes. The friction ring is arranged in an adjusting bridge in such a manner that it can be axially displaced about an adjusting path along the gap and the adjusting bridge is mounted by an individual, axial guiding device.

Abstract: The aim of the invention is to further develop a bevel friction ring gearing. The invention thus relates to a bevel friction ring gearing in which the friction ring can be displaced by means of an adjusting device that comprises a guide on which an adjusting bridge for the friction ring is arranged in a free axially displaceable manner. The adjusting device comprises a worm-gear drive that engages with the guide.

Abstract: A device for damping torsional vibration of a drive shaft with a liquid damping medium including a primary gear connected to the drive shaft. A secondary gear supports a series of planetary gears in meshed connection with the primary gear. The revolving primary gear and the planetary gears form a gear pump for closed circulation of the liquid damping medium through pressure ducts. The device further includes a control device for controlling the flow rate of the liquid damping medium based on the rotational speed of the primary gear.

Abstract: A device for changing the flow rate of a liquid damping medium is a torsional vibration damper. This damper has a rotating cylindrical damper housing, connected between a drive shaft and a power takeoff shaft. Pinions are surface-mounted in a planetary fashion without axle journals between the axial faceplates of a gear pump in recesses in the pump interior. The pinions are engaged with a central gear seated on the power takeoff shaft or on drive shaft, which form gear pumps for closed circulation of the damping medium.
