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.
Claims7
Friction-ring transmission having two roller bodies spaced apart from one another by a gap, which correspond with one another, rotating on axial roller body axes, by way of a friction ring, in which the friction ring is disposed to be displaceable axially, along the gap, by an adjustment path, in an adjustment bridge that is freely displaceable axially,
- wherein the adjustment bridge is mounted by means of only two guide devices, wherein a first guide device of said two guide devices is an axial guide device;
- said axial guide device enabling said adjustment bridge to be displaced axially while preventing all transverse movement of the adjustment bridge in a plane perpendicular to said adjustment path;
- and a second guide device of said two guide devices enabling said adjustment bridge to be displaced axially and allowing transverse movement of the adjustment bridge in a plane perpendicular to said adjustment path;
- said second guide device of said two guide devices being rigidly connected to a housing of said friction-ring transmission, and wherein said first guide device is tiltable.

- wherein the adjustment bridge is mounted by means of two guide devices, wherein a first guide device of said two guide devices is an axial guide device;
- said axial guide device enabling said adjustment bridge to be displaced axially while preventing all transverse movement of the adjustment bridge in a plane perpendicular to said adjustment path;
- and a second guide device of said two guide devices enabling said adjustment bridge to be displaced axially and allowing transverse movement of the adjustment bridge in a plane perpendicular to said adjustment path;
- and wherein said axial guide device being said cage, and wherein an axis of rotation of the cage is disposed on one side with regard to a plane predetermined by the roller body axes;
- and
- said first guide device being tiltable;
- and
- said second guide device being rigidly connected to a transmission housing.
