Title:
TOROIDAL CONTINUOUSLY-VARIABLE TRANSMISSION AND AIRCRAFT DRIVE MECHANISM-INTEGRATED POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/014880
Kind Code:
A1
Abstract:
Provided are a toroidal continuously-variable transmission and an aircraft drive mechanism-integrated power generation device which, by making an oil jet stream less susceptible to the influence of wind produced by rotation of a power roller, make it possible to supply a sufficient amount of oil to the power roller and perform sufficient cooling with the oil. 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; and an ejection member in which is formed an ejection port that ejects oil. The ejection member has a first oil channel and a second oil channel which communicate with each other within the ejection member, and oil within the first oil channel and oil within the second oil channel collide near the ejection port. The first oil channel and the second oil channel are arranged so that the oil jet stream has a flat shape that follows a rotation direction of the power roller.
