Cooling and lubricating mechanism of toroidal continuously variable transmission

摘要

Plural cooling passages 37a extending radially are formed from the inner circumference to the outer circumference and within an output disk 37 common to two toroidal transmission units. Lubricating oil which has reached an annular space between the output disk 37 and the main shaft 27 via holes 27f, 27g from an oil passage 27e in the main shaft 27, flows into the cooling passages 37a inside the output disk 37, and the output disk 37 is thereby cooled from inside. <IMAGE>
