Title:
TOROIDAL CONTINUOUSLY-VARIABLE TRANSMISSION AND AIRCRAFT DRIVE MECHANISM-INTEGRATED POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/014879
Kind Code:
A1
Abstract:
Provided are a toroidal continuously-variable transmission and an aircraft drive mechanism-integrated power generation device that appropriately supply oil both for lubricating contact interfaces between a power roller and each of disks and for cooling the power roller. The toroidal continuously-variable transmission comprises: an input disk and an output disk disposed facing each other; a power roller that is interposed between the input disk and the output disk in an inclinable state and that transmits rotational driving force of the input disk to the output disk at a transmission ratio based on an inclination angle; at least one lubrication ejection port that ejects oil toward a contact interface between the power roller and at least one of the input disk and the output disk; and at least one cooling ejection port that ejects oil toward the power roller. The cooling ejection port is disposed so that a distance between the cooling ejection port and a contact position of the oil ejected from the cooling ejection port is shorter than a distance between the lubrication ejection port and the contact interface.
