Title:
VALVE TIMING CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2020/039689
Kind Code:
A1
Abstract:
The device of the present invention comprises a bearing recess 10 that is provided in a part of the inner peripheral surface of a sprocket body 1a on a holding plate 8 side and has a sliding bearing surface 10a formed on the bottom surface, and a journal portion 11 that is provided to protrude radially outward from the outer peripheral surface of a disc-shaped body 9a, fits into the bearing recess 10 and slides by the outer peripheral surface on the sliding bearing surface 10a. Axial loads F1, F2 are received by an inner side surface 10b of the bearing recess 10 and an inner side surface 8f of an inner peripheral portion 8b of the holding plate 8 in a state where both end surfaces 11e, 11f of a journal portion 11 are sandwiched from both sides in the axial direction. As a result, the device can be reduced in size while suppressing the inclination of a drive rotor relative to a driven rotor.
