Title:
トロイダル無段変速機及び航空機用駆動機構一体型発電装置
Document Type and Number:
Japanese Patent JP7269123
Kind Code:
B2
Abstract:
Provided are: a toroidal continuously variable transmission that can create a jet of oil resistant to the influence of a wind generated by rotation of a power roller, thereby feeding a sufficient amount of oil to the power roller and achieving sufficient cooling of the power roller with the oil; and a drive mechanism-integrated electricity generation apparatus for an aircraft, the electricity generation apparatus including the toroidal continuously variable transmission. The toroidal continuously variable transmission includes: input and output discs opposed to each other; a power roller tiltably held between the input and output discs to transmit rotational drive power of the input disc to the output disc at a speed ratio determined by a tilt angle of the power roller; and a discharge structure including an outlet that discharges an oil. The discharge structure includes first and second oil passages connected with each other inside the discharge structure, and the first and second oil passages are arranged such that the oil flowing through the first oil passage and the oil flowing through the second oil passage collide with each other in the vicinity of the outlet and that a jet of oil discharged from the outlet forms a flattened shape extending along a rotational direction of the power roller.
