ABSTRACT:
The drive has axially opposed pairs of conical discs on parallel driving and driven shafts interconnected by a chain having traction members on the ends of the chain joint pins. The traction members are shaped to collect and wedge a high pressure lubricating film at the disc contacts. The driving shaft has lever control means for moving the discs axially to vary the drive speed ratio and the driven shaft has spring members maintaining chain tension. The driven shaft includes means limiting initial contact with the discs to permit graduated chain engagement and the chain link members have a rocking bearing contact with the pins.
