Abstract

PURPOSE: To improve transmission efficiency of a transmission wherein conical rotors making orbital friction motions with three elements are included, by holding each rotor with a retainer which has openings respectively larger than a sectional area of said rotor.
CONSTITUTION: A power transmission train between an input shaft 1 and an output shaft 2 is provided with a transmission element 5 connected to the input shaft, conical rotor 3, transmission element 6 connected to the output shaft and pressure generator 7 creating a thrust depending on an outut torque. The conical rotor 3 has a conical face 8, circular curved transmission face 9 in contact with the transmission element 5 and circular flat tranmission face 10 in contact with the transmission element 6. A shaft 12 projects at the center of the circular transmission face 10 and is inserted through each opening 13 drilled in a retainer 11, whose area is larger than a sectional area of the shaft 12. Therefore the retainer 11 can prevent rotors 3 from slipping so that transmission efficiency can be improved.
