Abstract
A friction-wheel epicyclic gear (10, 10a) is proposed. The friction-wheel epicyclic gear (10, 10a) has bevel wheels (12, 42), which roll on a friction wheel (14) and drive a gear output shaft (26). The contact pressure between the bevel wheels (12, 42) and the friction wheel (14) is variable. A detection of the slip between the bevel wheels (12, 42) and the friction wheel (14) is provided, and the contact pressure is variable as a function of the slip. In this way, the friction-wheel epicyclic gear (10, 10a) can always be operated at the slip limit, so that the wear is only slight and the efficiency is high.
