Abstract
A gearless mechanical transmission includes a housing which supports a high-speed shaft and a low-speed shaft along a main rotational axis. The housing also includes a precession link therein fixed for rotation about the high-speed shaft at an angle skewed with regard to the main rotational axis. A first cam surface is associated with the housing, a second cam surface with the low-speed shaft and a third and fourth cam surface with a precession link. Cam follower elements include rollers which establish rolling contact between the first and third and second and fourth cams respectively.
