Abstract
A toroidal continuously variable transmission. A power roller (40) of the transmission includes a power roller inner ring (50) sandwiched between both disks (1, 2), a power roller outer ring (60) provided in a trunnion (35) and rotatably supporting the power roller inner ring (50), and an inner ring hole (52) provided in the power roller inner ring (50) to extend in an axial direction of the power roller inner ring (50), in which an end surface hole (58) communicating with an inner ring hole (52) is provided in an inner end surface (54) of the power roller inner ring (50), and the end surface hole (58) is closed by a closing member (80) separate from the power roller inner ring (50).
Claims9
A toroidal continuously variable transmission comprising:
- an input side disk and an output side disk that are concentrically and rotatably provided with inner surfaces facing each other;
- a power roller sandwiched between both disks;
- and
- a trunnion that rotatably supports the power roller and is tilted about pivot shafts that are at twisted positions with respect to central axes of the input side disk and the output side disk,
- wherein the power roller includes a power roller inner ring sandwiched between the both disks, a power roller outer ring that is provided in the trunnion and rotatably supports the power roller inner ring, and an inner ring hole provided in the power roller inner ring so as to extend in an axial direction of the power roller inner ring,
- wherein an end surface hole communicating with the inner ring hole is provided in an inner end surface of the power roller inner ring, and the end surface hole is closed by a closing member separate from the power roller inner ring, attached from a side of the inner end surface of the power roller inner ring, and
- wherein the closing member is formed with a plurality of claws that extend in the axial direction from the closing member and are inserted into the end surface hole.
