Abstract
A friction drive (10) having a plurality of planet assemblies (24A, 24B, 24C) pivotally mounted to a carrier (12), a sun shaft (14) rotatably mounted with the carrier (12) and having a first raceway (16), and an outer ring member (18) having a second raceway (22) concentric to the first raceway (16) and having a ring shaft (20). The plurality of planet assemblies (24A, 24B, 24C) frictionally engaged with the first raceway (16) and the second raceway (22) for transferring power between the sun shaft (14) and the outer ring member (18).
