Title:
VALVE TIMING ADJUSTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/189482
Kind Code:
A1
Abstract:
A drive side rotating body (20) rotates in conjunction with a crankshaft. A driven side rotating body (30) rotates integrally with a camshaft about a rotation center line (Cr1). An internally toothed gear portion (40) is formed in the driven side rotating body (30). A planetary rotating body (50) has a planetary gear portion (51) which is eccentric relative to the rotation center line (Cr1) and which meshes with the internally toothed gear portion (40). An Oldham coupling (60) includes a driven Oldham flange portion (61) formed in the drive side rotating body (20), a drive Oldham flange portion (62) formed in the planetary rotating body (50), and an Oldham intermediate body (63) which causes the driven Oldham flange portion (61) and the drive Oldham flange portion (62) to rotate synchronously and with freedom to rotate eccentrically. If the maximum amount of inclination of the planetary rotating body (50) with respect to the driven Oldham flange portion (61) is θ1 and the maximum amount of inclination of the planetary rotating body (50) in a clearance in the Oldham coupling (60) is θ2, the relationship θ2<θ1 is satisfied.
