Abstract
The friction gear disclosed includes driven and driving shafts whose rotational axes are parallel to but spaced from each other. One of the shafts has an axial bearing surface mounted on its facing end. The other shaft includes means for mounting at least two rollers that are spaced from the rotational axis of the one shaft and that bear against the axial bearing surface. While several different embodiments are disclosed, the means for mounting and aligning the rollers holds each of the rollers such that its rotational axis is directed toward and intersects a straight line which extends parallel to the rotational axes of the shaft and which lies in a plane determined by the two rotational axes of the shafts.
