SUPPORT AND LUBRICATION SYSTEM FOR CONTINUOUS CASTING MACHINE ROLLERS ABSTRACT OF THE DISCLOSURE A roller assembly for such as supporting a strand of metal cast in a continuous casting machine and the like is disclosed as having a shaft adapted to be journaled in supporting arms at axially spaced locations along the shaft. A plurality of axially spaced bearings are mounted on the outer periphery of the shaft. A plurality of axially spaced cylindrical shells are provided with each mounted on the outer periphery of a pair of bearings. At least one axial end of the shaft is bored to define at least four axially inwardly projecting lubricating passages to the bearings. A lubricant measuring and distributing valve assembly is mounted on the bored end of the shaft. The valve assembly has a body defining two lubricant inlets and four outlets aligned with the four shaft passages. Each of the inlets alternate in delivering lubricant to a pair of flow regulating valves. A pair of volume measuring valves are provided within the body and with each connected to one regulating valve and each of the flow regulating valves operate to transmit lubricant from either of the two inlets to its connected volume measuring valve. Each volume measuring valve operates to receive a first predetermined volume of lubricant from the regulating valve connected thereto and thereafter each measuring valve receives a second such volume of lubricant which actuates the measur- ing valves to expel each of the first volumes of lubricant to its respective outlet which is aligned with one of the shaft passages. Each measuring valve then receives a third volume of lubricant from its regulating valve to replace its expelled first volume and actuate the measuring valves to expel each second volume of lubricant to other outlets aligned with other of the shaft passages. Alternating delivery of pressurized lubricant to the two inlets results in the delivery of measured volumes of lubricant through four outlets to aligned passages in the assembly shaft. The valve body may also be connected to the shaft and supporting structure to retain the shaft in proper alignment.
