<p><P>PROBLEM TO BE SOLVED: To achieve a structure that minimizes the power loss while ensuring the required cooling capacity. <P>SOLUTION: Torque transmission is performed between a sun roller and an annular roller by a plurality of intermediate rollers 27, 27 disposed between the outer peripheral surface of the sun roller and the inner peripheral surface of the annular roller. Traction oil is supplied to traction parts, being rolling contact parts of the peripheral surfaces of the respective rollers, through supply channels 41, 41 provided in columns 36, 36 of a carrier 33 for supporting the respective intermediate rollers 27, 27. It is configured to set the supply amount to the inner-diameter side traction parts larger than that of to the outer-diameter side traction parts. The inner-diameter side traction parts are the rolling contact parts between the outer peripheral surface of the sun roller and the outer peripheral surfaces of the respective intermediate rollers 27, 27. The outer-diameter side traction parts are the rolling contact parts between the outer peripheral surfaces of the respective intermediate rollers 27, 27 and the inner peripheral surface of the annular roller. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
