Abstract: The present disclosure relates to a machine head reducer or assembly, including a housing with a central axis and a surface with a plurality of undulations substantially parallel and equidistant to the central axis, a first driven member having a central axis which is substantially concentric with the housing central axis, a second axis parallel and eccentric to the central axis, a second driven member having a central axis substantially concentric with the second axis of the first driven member with a first surface having a plurality of undulations in mesh contact with the undulations of the housing surface, a second surface having a plurality of undulations where the undulations of the first surface and the undulations of the second surface are parallel and equidistant to the second driven member central axis.
