Conical drive.

摘要

Conical drives for changing the speed of an output shaft (12) relative to aninput shaft (10) include a conical coupling between the output shaft and and a conical driving member (30;62) within the drive. The output and input shafts are aligned with a first axis (14) and the conical driving member (30;62) rolls around the first axis without slipping while rotating about a second axis (27) disposed obliquely with respect to and intersecting the first axis at a coincidence point (38;85). The apexes of the conical coupling and the conical driving member are coincident with the coincidence point. The conical coupling is utilised with both single and multispeed drives.
