A planetary-roller transmission for transmitting power from one rotating shaft to another by means of a plurality of planet rollers pivotally supported, in contact with the outer periphery of a sun roller fixedly mounted on one rotating shaft and also with the inner periphery of an internal contact ring secured to a stationary member and made unmovable circumferentially of the rotating shaft, by a carrier connected to the other rotating shaft, characterized in that either the internal contact ring or the sun roller or both are in the form of an elastic element or elements adapted to receive, on one side thereof, a compressive force axially of the rotating shafts to change the radius of the element surface in pressure contact with the mating rollers, and a presser device is provided which applies the compressive force to one side of each elastic element and brings the element into or out of engagement with the mating rollers by increasing or decreasing the compressive force.
A planetary-roller transmission comprising:
A planetary-roller transmission device for transmitting power from one rotating shaft to another by means of a plurality of planet rollers so supported by a carrier connected to said other rotating shaft as to be in contact with the outer periphery of a sun roller fixedly mounted on said one rotating shaft and also in contact with the inner periphery of an internal contact ring secured to a stationary member and made immovable circumferentially of said one rotating shaft, characterized in that at least one of said internal contact ring and said sun roller are provided in the form of an elastic roller or elastic rollers of U shape in cross section respectively so that it can be reduced in width under an axially compressive force of said one rotating shaft and its pressure contact surface with the mating rollers transformed into a crowned shape until its radius is changed, and presser means provided for applying said compressive force to one side of said elastic roller to cause it to engage, or be disengaged from, said mating rollers by increasing or decreasing said compressive force.
