Abstract
A valve timing controller includes a first rotary element having a first gear part, a second rotary element having a second gear part, and a planetary gear including a third gear part and a fourth gear part which respectively engage with the first gear part and the second gear part. The planetary gear performs a planetary motion to vary a relative rotational phase between the first rotary element and the second rotary element. The valve timing controller further includes a supporting member supporting the planetary gear in such a manner that the planetary gear is slidable in its axial direction between the first rotary element and the second rotary element, and an elastic member restricting a displacement of the planetary gear in its axial direction.
Claims6
A valve timing controller for controlling valve timing of at least one of an intake valve and an exhaust valve, comprising:
- a first rotary element rotating in response to one of the crankshaft and the camshaft, and including a first gear part;
- a second rotary element rotating in response to the other of the crankshaft and the camshaft, and including a second gear part;
- a planetary gear including a third gear part and a fourth gear part which respectively engage with the first gear part and the second gear part, the planetary gear performing a planetary motion to vary a relative rotational phase between the first rotary element and the second rotary element;
- a supporting member supporting the planetary gear in such a manner that the planetary gear is slidable in its axial direction between the first rotary element and the second rotary element;
- and
- an elastic member restricting a displacement of the planetary gear in its axial direction.
