TITLE OF THE INVENTION: Lubricating System and Method INVENTOR: Donald R. MacLeod ASSIGNEE: REXNORD INC., a Wisconsin corporation ABSTRACT OF THE DISCLOSURE: A series of conveyor idler roll shafts in end-to- end relation supported by bearings provides a pressurized chamber for the flow of grease or oil to the bearings from a reservoir, which is capable of pumping the lubricant into the axial bore of each shaft. Small, radially directed holes connect the shaft bores to the bearings by providing a restricted passage having across it a suitable pressure drop capable of allowing lubricant to flow in sufficient quantities to each bearing regardless of its distance from the reservoir pressure source. Adjacent shaft ends are connected with a resilient cylindrical tubular coupler to provide the requisite flow passage continuity. A labyrinth seal provides a continuous path for lubricant to flow through the bearings, the seal and ultimately to the ex- terior of the system, where its appearance is visible and indicative of adequate lubricant flow to each bearing along the shaft assembly.
