Patent Searching and Data


Title:
TOROIDAL CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2018/092681
Kind Code:
A1
Abstract:
The purpose of the invention is to achieve a structure that can be easily made smaller while maintaining transmission efficiency and durability. An inner disk 8b is supported around a sleeve 5a so as to be able to rotate relative to a rotational shaft 2b and the sleeve 5a by way of a pair of ball bearings 33 having a face-to-face type contact angle. A pair of conical disc springs 36 are held between the inner face of an outer ring 35 of each of the pair of ball bearings 33 and an inner diameter side step face 30 on each of a pair of disk elements 7a, and a preload in the axial direction is applied to the pair of ball bearings 33 by elastically pressing the outer ring 35 to the outside.
