Title:
FRICTION ROLLER TYPE TRANSMISSION
Document Type and Number:
Japanese Patent JPH1172152
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a structure which can be constituted in a small type and by which high transmission efficiency can be obtained in spite of a change in torque to be transmitted. SOLUTION: An inner ring 33 whose outer peripheral surface is formed as a conical projecting surface, is supported in an intermediate part of an input shaft 26 so as to be freely displaceable in the shaft direction. Transmission rollers 40 whose respective ones are formed in a hollow conical roller shape, are sandwiched between an outer peripheral surface 34 of this inner ring 33 and an inner peripheral surface 36 of a fixed outer ring 35. A pivot 38 to pivot these respective transmission rollers 40 is joined to an output shaft 30. A loading cam device 42 is also arranged between the input shaft 26 and the inner ring 33.
