TRANSMISSION
Document Type and Number:
Japanese Patent JPS5973652
Kind Code:
A
Abstract:
PURPOSE:To form a transmission, which has quiet operating noise and can take out a differential output and at the same time has an extremely small torque loss by a structure wherein two groups of rotatable planet rollers are arranged between a sun roller and two inscribed rings, the inner diameters of which are different from each other and in which the planet rollers inscribe. CONSTITUTION:Quiet operating noise is obtained by realizing rolling contacts among all of a sun roller 1, first planet rollers 2, second planet rollers 3, and two inscribed rings 4 and 5. In addition, the configurations and axis directions of all the rollers and rings are determined by arranging the groups of the first planet rollers 2 and of the second planet rollers 3 among the sun roller 1 and the inscribed rings 3 and 5. Furthermore, a differential output, the speed variation ratio of which is maximum, can be taken out by the combination of the two inscribed rings, the inner diameters of which are different from each other, and the groups of the second planet rollers 3, the roller diameters of which are different from each other and yet which are rotatable separately. No controlling member for determining the positions around the sun roller 1 and posture (axis direction) of the respective planet rollers 2, 31, and 32 is employed, resulting in eliminating torque loss to be developed by the existence of controlling member.
