Title:
SHAFT SUPPORT STRUCTURE FOR BELT-TYPE STEPLESS TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2014/155835
Kind Code:
A1
Abstract:
Provided is a shaft support structure for a belt-type stepless transmission, the shaft support structure being configured so that the length of a shaft on which a torque cam is provided can be reduced.
A first bearing (36), which supports both a rotating shaft (11) and a torque cam (15) so that the rotating shaft (11) and the torque cam (15) can rotate relative to each other, is provided between the outer peripheral surface of the rotating shaft (11) and the inner peripheral surface of the torque cam (15). A second bearing (42), which rotatably supports one axial end of an output member (16) on a case (31), is provided on the outer peripheral side of the first bearing (36) in the radial direction. A space is formed at a position on the inner peripheral side of the second bearing (42) and on the outer peripheral side of the torque cam (15). A seal member (32) which is fitted to the outer peripheral surface of the torque cam (15) is installed in the space.
