Abstract:
1. A chain lubricating apparatus for delivering lubricating fluid to a sprocket-driven chain, comprising: a sprocket comprising an inner sprocket section and an outer sprocket section with teeth that engage the chain, the sprocket being rotatable about an axis; at least one disc being positioned adjacent to and substantially coaxially with the sprocket, and configured to be rotatable about the axis; a lubricant source; a lubricant delivery means; and a lubricant return path; wherein during operation of said sprocket-driven chain, the inner sprocket section and at least one disc independently rotate about said axis relative to each other and the lubricant delivery means is configured to deliver lubricant to a predetermined part of said chain when said inner sprocket section is positioned at a predetermined angular position relative to said at least one disc around said axis and the lubricant return path allows excess lubricant that is expelled by said lubricant delivery means to return to the lubricant source when said inner sprocket section is positioned at another predetermined angular position relative to said at least one disc around said axis.
