PROBLEM TO BE SOLVED: To provide a conical ring transmission to be as less worn as possible. SOLUTION: The conical ring transmission 1 comprises two opposed conical friction wheels 2, 3, and a friction ring 8 encircling one of the conical friction wheels 2, 3. The friction ring 8 engages with the encircled conical friction wheel 2 via an internal contact surface 12 and engages with the other conical friction wheel 3 via an external contact surface 13. The cross section of at least one of the contact surfaces 12, 13, perpendicular to the rotating direction of the friction ring 8, has a profile P based on a relationship P(x)=A ln(F(x)), where P(x) is a profile function, x is a distance between centers 22, 23 of the contact surfaces 12, 13, F(x) is a function as the argument of a logarithmic function In, and A is a factor.
