Abstract
A lubricating system for a toroidal continuously variable transmission equipped with a trunnion rotatably supporting a power roller gripped between input and output disks so that a gyration angle of the power roller is variable, includes a first lubricating circuit provided for lubrication of a rolling contact surface on which the input and output disks are in friction-contact with the power roller, and a second lubricating circuit provided for lubrication of the trunnion and the power roller. Also provided in the first lubricating circuit is an oil-temperature control device that heats oil of the toroidal continuously variable transmission, so that the oil temperature-controlled by the oil-temperature control device is supplied through the first lubricating circuit into the rolling contact surface.
