ABSTRACT:
A guide bar for a chain saw having interior channels for conducting fluid to a nose end of the bar. The channel conducts fluid to the nose end of the bar where a sprocket is rotatably mounted. The sprocket has grooves formed in each side of its body for injecting fluid received from the center channel into the supporting bearing surface in the bore of the sprocket. The grooves are configured to inject fluid to the bearing surfaces regardless of the direction of sprocket rotation. The grooves which have open tops also provide for fluid flow between the side of the sprocket body and the side laminates of the sprocket nose. The grooves also provide an exit for fluid to flow out of the bearing surface as the grooves are positioned opposite the center channel as the sprocket is rotated. The flow of fluid through the grooves into the bearing area and the flow of fluid between the sprocket and the side laminates provides a hydraulic wall to prevent entry of contaminants into the sprocket.
