Problems solved by technology

In this solution, however, operating states can arise in which the edge of the friction ring starts up on the edge of the step and leads to material wear and, in the worst case, damage to the friction ring

Embodiment Construction

[0023] The conical friction ring transmission 1 shown in the drawing comprises an outer cone 21 , an inner cone 11 and a friction ring 31 surrounding this inner cone 11 .

[0024] In order to limit the position of the friction ring 31 and to position it securely, the outer cone 21 of the conical friction ring transmission 1 has an outer step 23 at the constricted end of the outer cone running surface 22 . This outer step 23 also delimits the outer cone rolling surface 22 to the outer cone shaft 28 on which the outer cone 21 generally has a bearing. In this exemplary embodiment, the outer step 23 therefore additionally serves as a contact surface for the bearing on the outer tapered shaft 28 .

[0025] In order to securely position the friction ring 31 on the outer step 23 the outer step 23 also has an outer conical contact surface 24 which in this embodiment is aligned parallel to the outer friction surface 35 of the friction ring 31 .

[0026] The outer cone running surface ...

Abstract

The invention relates to a conical friction ring transmission, which is provided with at least an inner conical portion, at least an outer conical portion, and at least a friction ring enclosing the inner conical portion and disposed between the inner conical rolling surface of the inner conical portion and the outer conical rolling surface of the outer conical portion. Startup of the friction ring on the conical step is realized in a way that components of the conical friction ring transmission are not damaged. The friction ring has a circular friction ring outer edge between the friction ring outer surface and the outer friction surface, whose radius is 0.3-0.8 times of the friction ring width (B). The outer conical portion has a circular outer shoulder edge between the outer conical contact surface and the outer step surface, whose radius is 0.05-0.2 times of the friction ring width.

Description

technical field [0001] The invention relates to a conical friction ring transmission having at least one inner cone, at least one outer cone and at least one friction ring surrounding the inner cone. Background technique [0002] A large number of such conical friction ring transmissions are known in the prior art, it being possible for such known conical friction ring transmissions to have a friction ring freely displaceable in translation in such a way that the friction ring is arranged pivotably about an axis And it itself moves into frictional contact with the rotation about this pivot axis by the frictional force acting on it. A movement of the friction ring along the axis of rotation of the inner or outer cone is thereby achieved. The pivot axis of the friction cone lies in a plane which is supported by the axes of rotation of the inner and outer cones and is approximately at right angles to them. The angle of rotation is likewise at right angles to the axis of rotat...
