JOINT STRUCTURE OF YOKE AND ROCKER ARM OF VESSEL ENGINE

摘要

The present invention relates to a yoke which opens and closes a valve of an engine, and more specifically, to a structure for joining a yoke and a rocker arm of a vessel engine which blocks a rocker arm rotating in a vertical direction and a horizontal shaking movement of a yoke moving linearly by rotation of the rocker arm to improve durability. The structure for joining a yoke and a rocker arm of a vessel engine comprises: a push rod which moves vertically and is extended above a cylinder head; a rocker arm disposed on an upper portion of the cylinder head, wherein both ends thereof rotate about a rocker shaft in opposite directions, and one side thereof is mounted on the push rod by a boll joint; and a yoke mounted on the other side of the rocker arm and provided with a valve stem mounted thereon in a downward direction. A first stopper is formed on any one side of portions of the yoke and the rocker arm facing each other, and a pair of second stoppers is formed on the other side to support both sides of the first stopper. Even when the yoke rotates vertically by rotation of the rocker arm rotated by the push rod, the first stopper is positioned inside the second stoppers without escaping from the second stoppers to prevent the yoke from shaking in a left and a right direction.
