Abstract
Conical drives for changing the speed of an output shaft relative to an input shaft include a conical coupling between the output shaft and a conical driving member within the drive. The output and input shafts are aligned with a first axis and the conical driving member rolls around the first axis without slipping while rotating about a second axis disposed obliquely with respect to and intersecting the first axis at a coincidence point. The apexes of the conical coupling and the conical driving member are coincident with the coincidence point. The conical coupling is utilized with both single and multispeed drives.
