<p>A drive unit (10) for a press uses an oil shear brake (110,116,118,120) and an oil shear clutch (130,134,136,138) which are located axially along the output member of the drive unit. A single piston (150) 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 (10) through the output member and lubricating oil is received from the drive member through a stationary support member. <IMAGE></p> |
