摘要： A toroidal continuously variable transmission includes: an input disc; an output disc; a power roller; a trunnion; a support that supports the power roller such that the power roller is rotatable relative to the trunnion; a thrust bearing that receives a load of the rotating power roller in a direction along a rotation axis of the power roller; and an oil passage through which lubricating oil is supplied to the thrust bearing. An opposing surface of the power roller which surface is opposed to the support includes a first bearing groove. An opposing surface of the support which surface is opposed to the power roller includes a second bearing groove. A virtual axis of a discharge port of a nozzle included in the oil passage reaches a bearing groove that is one of the first bearing groove and the second bearing groove. When viewed from a direction perpendicular to the direction along the rotation axis, a portion of a retainer which portion is located at a radially inner side of a retaining hole of the retainer and a portion located at a radially inner side of the bearing groove are located at respective sides opposite to each other across the virtual axis and away from the virtual axis.

摘要： 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.

摘要： A toroidal continuously variable transmission includes: first and second pistons attached to a shaft portion of a trunnion so as to be externally fitted to the shaft portion, the first and second pistons being arranged so as to be lined up in a direction along a tilt axis; and a cylinder forming a first pressure chamber which makes the first piston move toward a first side in the direction along the tilt axis and a second pressure chamber which makes the second piston move toward a second side in the direction along the tilt axis. The cylinder includes a first lubricating oil passage, and the shaft portion of the trunnion includes a second lubricating oil passage. A third lubricating oil passage through which the first lubricating oil passage communicates with the second lubricating oil passage is formed between the first piston and the second piston.
