Title:
FRICTION ROLLER TYPE DECELERATION DEVICE AND DRIVE DEVICE FOR ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2012/124640
Kind Code:
A1
Abstract:
In order to implement a structure whereby an intermediate roller (19) can be displaced in a smooth manner in conjunction with changes in the axial-direction thickness of a loading cam device (7a), and excellent transmission efficiency can be obtained, a long guide hole (35), which is longer in the radial direction of a sun roller (4a) and a circular roller (5a), is provided in a guide block (34) which is affixed to a support frame (32) for the purpose of supporting the ends of the rotating shaft (20) of the intermediate roller (19) in a rotatable manner. In addition, the outer ring of a ball bearing (36), the inner ring of which is fitted around the outside of the ends of the rotating shaft (20), engages the long guide hole (35) so as to enable displacement of the sun roller (4a) and the circular roller (5a) in the radial direction.
