Lubricating mechanism of toroidal continuously variable transmission

Abstract

A lubricating mechanism of a toroidal continuously variable transmission comprises a first supply port (107) for supplying lubricating oil to a contact surface of an input disk (17, 19) and output disk (18, 20) with a power roller (70, 71, 170, 171), and a second supply port (114) for supplying lubricating oil to a bearing (71A) supporting the power roller (70, 71, 170, 171) on a trunnion (72, 73) are provided. A first oil passage (105, 106) for connecting the oil pump (5) to either one of the first supply port (107) and second supply port (114), and a second oil passage (108, 109, 110, 112, 113) for connecting an oil cooler (50) to the other one of the first supply port (107) and second supply port (114), are provided. Insufficiency of lubricating oil is prevented by having two different sources to supply lubricating oil to the bearing (71A) and the contact surface of the power roller (70, 71, 170, 171).
