Title:
VALVE TIMING ADJUSTMENT DEVICE
Document Type and Number:
Japanese Patent JP2020148186
Kind Code:
A
Abstract:
To provide a valve timing adjustment device which can improve transmission efficiency in the Oldham joint with a simple configuration.SOLUTION: A planetary rotor 50 is eccentric to a rotational center line Cr1. An Oldham joint 60 includes: a driven Oldham flange part 61 formed at a driven-side rotor 20; a driving Oldham flange part 62 formed at the planetary rotor 50; and an Oldham intermediate body 63 which rotationally synchronizes the driven Oldham flange part 61 and the driving Oldham flange part 62 in a freely eccentric manner. A thrust part 90 is formed at a rotor plate part 22 which is a part other than the Oldham joint 60, and can restrict an inclination of the planetary rotor 50 with respect to the driven Oldham flange part 61 by coming into contact with the planetary rotor 50 in a direction of the rotational center line Cr1. When a maximum inclination amount of the planetary rotor 50 with respect to the driven Oldham flange part 61 is θ1 and a maximum inclination amount of the planetary rotor 50 in a clearance in the Oldham joint 60 is θ2, a relationship of θ2>θ1 is satisfied.SELECTED DRAWING: Figure 4
