Abstract
A drive unit for a press uses an oil shear brake and an oil shear clutch which are located axially along the output member of the drive unit. A multiple piece piston moves between a brake applied/clutch disengaged position to a brake released/clutch engaged position under the influence of a hydraulic pressure. Cooling and lubrication oil is provided to the drive unit through the output member and lubricating oil is received from the drive member through a stationary support member. An adjustment member is capable of adjusting the gap between the piston and the clutch and brake units in order to eliminate any overlap between these two units.
