Internal oil flow path for gear box bearings

摘要

An apparatus for modifying a gear casing used in coal pulverizer mills prevents lubricating oil leaks through worn O-rings by redirecting the oil in a different path which does not come into contact with the O-ring seals. An internal hose connection provides oil directly to a bearing top chamber through a passage in the bearing cartridge. A special connector is used to connect the internal hose to the passage. Several connector embodiments are disclosed.
