OIL SEAL PACKING LUBRICATING SYSTEM OF MANUAL TRANSMISSION

摘要

An oil seal packing lubricating system of a manual transmission in which the lubricant is supplied from outside of the oil seal packing, including a lubricant introducing rib for guiding the lubricant fed from outside to a lip surface of the oil seal packing in a zone where an outer surface of the input shaft moves upwardly during its rotation, and at least one lubricant deflecting rib for deflecting a swirling flow of lubricant toward the lip surface of the oil seal packing. The Lubricant deflecting rib is shaped such that it draws nearer to the outer surface of the input shaft in going in the direction of rotation of the input shaft.
