摘要： Provided is a toroidal continuously variable transmission that can create a jet of oil resistant to the influence of wind generated by rotation of a power roller, thereby feeding a sufficient amount of oil to the power roller to cool 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 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 arranged such that the oil flowing through the first oil passage and 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.

摘要： Provided is a toroidal continuously variable transmission that can achieve suitable oil feed both for lubrication at contact interfaces between a power roller and discs and for cooling of the power roller; 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 at least one lubrication outlet that discharges an oil toward at least one contact interface between an input or output disc and the power roller; and at least one cooling outlet that discharges the oil toward the power roller. The cooling outlet and the lubrication outlet are arranged such that a distance between the cooling outlet and a point at which the oil discharged from the cooling outlet contacts the power roller is smaller than a distance between the lubrication outlet and the contact interface.

摘要： A planetary gear device includes: a sun gear; a plurality of planet gears that mesh with the sun gear; and a baffle unit disposed in a circumferential gap between the adjacent planet gears. The baffle unit includes: a first introduction opening portion open in a radially inward direction to introduce lubricating oil, which has lubricated the sun gear and the planet gears, into the baffle unit; an end wall forming one end in an axial direction of the first introduction opening portion; a discharge opening portion to discharge lubricating oil in the baffle unit; and a guide portion disposed at a side portion of the baffle unit on a rear side in rotation direction of the sun gear, and configured to cover the first introduction opening portion in the circumferential direction and to guide the lubricating oil to an outer circumference of the adjacent planet gears.
