Two types of traction-drive testing machines were designed and made to analyze changes in the speed ratio and the power transmission efficiency of a planetary traction drive. One of the trial testing machines is of the two-roller-type with two continuously variable speed drives. This machine is used to analyze the effects of spin motion upon both the shape of the traction-coefficient curve and the power transmission efficiency between two taper-rollers. The other trial testing machine belongs to a planetary traction drive with a contact-pressure control device. Changes in the speed ratio and power loss caused by the spin motion in the planetary traction drive can be exactly predicted by the two-roller-type testing machine. Prediction of the total efficiency of the planetary traction drive becomes almost complete when the oil churning and rolling bearing losses are taken into account in the calculation.
