Title:
TRACTION POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2015086990
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce minute backlash between a planetary roller and a planetary shaft member in a traction power transmission device.SOLUTION: A first contact point 61 between each planetary roller 44 and an internal ring 5 and a second contact point 62 between each planetary roller 44 and a sun roller 33 are located in different positions with respect to a direction of a planetary shaft J2 to which the planetary shaft J2 being a center shaft of a planetary shaft member 43 which supports each planetary roller 44 is directed. In a cross section formed of a face including the planetary shaft J2, the first contact point 61 and the second contact point 62, as regards each planetary roller 44, a first pressing force vector V1 indicating first pressing force acting on each planetary roller 44 from the internal ring 5 is inclined to one side with respect to a linear line which connects the first contact point 61 and the second contact point 62, and a second pressing force vector V2 indicating second pressing force acting on each planetary roller 44 from the sun roller 33 is inclined to the other side with respect to the linear line.
