Toroidal type continuously variable transmission supported by a common bearing and reaction stationary shaft

摘要

In a toroidal type continuously variable transmission having an input disk, an output disk and power rollers sandwiched and frictionally engaged between the input and output disks so as to transmit rotational power therebetween at a transmission ratio variable according to the inclination of the power rollers relative to the input and output disks, a stationary shaft is provided as supported by a housing, and the input and output disks are rotatably supported by the stationary shaft via individual radial bearing means and individual axial bearing means. The stationary shaft has an axial bore and transverse orifices, and the bearings are lubricated by lubrication oil supplied through the axial bore and the transverse orifices.
