A drive unit for a press uses an oil shear brake unit and an oil shear clutch unit. The actuation of the brake unit and the clutch unit occurs simultaneously due to a common activation member. The oil cooling system for the drive unit feeds oil to the outer radial or circumferential portion of the drive and returns oil for the central portion of the drive. The reverse flow of oil provides a more consistent supply of cooling oil to remove heat and lubricate the various components of the drive unit to significantly improve the operating performance of the drive.

[ What is claimed is:] [1.] A drive assembly for a press having a flywheel, a frame and a drive shaft, said drive assembly comprising:an oil shear brake unit adapted to be disposed between said frame and said drive shaft, said brake unit including a plurality of interleaved first friction disks adapted to be alternately attached, respectively, to said frame and said drive shaft;an oil shear clutch unit adapted to be disposed between said flywheel and said drive shaft, said clutch unit including a plurality of interleaved second friction disks adapted to be alternately attached, respectively, to said flywheel and said drive shaft, said brake unit and said clutch unit defining a chamber, said chamber including an exterior wall defined by a continuously rotating member of said drive assembly;an oil inlet extending into said chamber, said oil inlet providing cooling oil to a radial outer portion of said chamber, said cooling oil being urged toward said exterior wall due to centrifugal forces generated by said continuously rotating member of said drive assembly;an oil outlet extending into said chamber, said oil inlet removing cooling oil from a central portion of said chamber; andan oil flow passage extending between said oil inlet and said oil outlet, said first and second friction disks being disposed within said oil flow passage, said cooling oil flowing from said oil inlet to said oil outlet against said urging of said cooling oil by said centrifugal forces.
