TOROIDAL CONTINUOUSLY VARIABLE TRANSMISSION

摘要

There is provided a toroidal continuously variable transmission including an input side disk and an output side disk which are provided to be concentric with each other and rotatable in a state where inner side surfaces thereof face each other, and a power roller which is interposed between the input side disk and the output side disk. At least one of the input side disk and the output side disk is configured as a gear disk which has teeth on an outer circumferential portion thereof. Each tooth on the outer circumferential portion of the gear disk is provided with a protruding portion which outwardly protrudes in a radial direction of the gear disk and has a width narrower than a width of the teeth in an axial direction of the gear disk. A tip end surface of the protruding portion serves as a processing reference of the gear disk.

1. A toroidal continuously variable transmission comprising:
an input side disk and an output side disk which are provided to be concentric with each other and rotatable in a state where inner side surfaces thereof face each other; and a power roller which is interposed between the input side disk and the output side disk, wherein at least one of the input side disk and the output side disk is configured as a gear disk which is integrated with a gear by forming teeth on an outer circumferential portion of the gear disk, and wherein each tooth on the outer circumferential portion of the gear disk is provided with a protruding portion which outwardly protrudes in a radial direction of the gear disk and has a width narrower than a width of the teeth in an axial direction of the gear disk, and a tip end surface of the protruding portion serves as a processing reference of the gear disk.
