Abstract
A traction drive unit for transmitting rotary motion about an axis of rotation has an inner sun roller, an outer ring and planet rollers arranged in two circular rows between the sun roller and outer ring. The sun roller takes the form of a double cone having outwardly presented raceways which taper downwardly toward each other and thrust ribs that project radially beyond the large ends of the raceways. The outer ring has two inwardly presented tapered raceways which taper downwardly toward the ends of the ring. The inner planet rollers are tapered rollers which are organized in two circular rows along the raceways of the sun member. The outer planet rollers have crowned peripheral surfaces which contact the tapered raceways of the outer ring and the tapered side surfaces of the inner planet rollers. They are captured axially by reason of the taper of the outer raceways and inner planet rollers. The outer rollers revolve in pairs about axles which are fitted to end disks.
