- 7. The press as recited in claim 4, wherein oil accessing said clutch means via said first means being effective in substantially eliminating free undamped clearances within said clutch means.
- 8. The press as recited in claim 7, further comprising:
- a mount assembly including a plurality of mounting elements arranged to secure said clutch means to at least one of said input means and said flywheel, each one of said plurality of mounting elements having at least one free clearance space associated therewith which is substantially filled by oil accessing said clutch means via said first means.
- 9. A press in combination with an oil shear clutch brake unit, said press including a shaft and flywheel with an oil filled bearing, said oil clutch brake unit comprising:
- support means for supporting said clutch brake unit within said press;
- input means for receiving rotary motion from said flywheel, said input means rotatable with respect to said support means;
- output means for transmitting rotary motion from said clutch brake unit to said press shaft;
- selectively operable clutch means for transmitting rotary motion from said input means to said output means, said clutch means including a plurality of interleaved friction disks;
- selectively operable brake means for applying a braking action to said output means to inhibit rotary motion of said press shaft, said brake means including a plurality of interleaved friction disks;
- a housing to house said support means, said input means, said output means, said clutch means, and said brake means; and
- first means for enabling fluid communication between said flywheel bearing and at least said clutch means to allow oil present within said flywheel bearing to access at least said clutch means.
- 10. The press of claim 9 in which said oil filled flywheel bearing drains oil into said housing to lubricate said clutch means.
- 11. The press as recited in claim 9, further comprising:
- a slidable actuator plate disposed between said clutch means and said brake means, the operative sliding of said actuator plate selectively actuating one of said clutch means and said brake means; and
- at least one hydrostatic fluid bearing each disposed at a respective side of said actuator plate in facing opposition to at least one of said clutch means and said brake means.
- 12. The press as recited in claim 9, further comprising:
- second means for selectively introducing fluid into said clutch brake unit to lubricate at least said clutch means, said second means being operable independently of said first means.
- 13. The press as recited in claim 9, wherein oil accessing said clutch means via said first means being effective in substantially eliminating free undamped clearances within said clutch means.
- 14. The press as recited in claim 13, further comprising:
- a mount assembly including a plurality of mounting elements arranged to secure said clutch means to at least one of said input means and said flywheel, each one of said plurality of mounting elements having at least one free clearance space associated therewith which is substantially filled by oil accessing said clutch means via said first means.
- 15. A press in combination with an oil shear clutch brake unit, said press including a shaft and flywheel with an oil filled bearing, said oil clutch brake unit comprising:
- support means for supporting said clutch brake unit within said press;
- input means for receiving rotary motion from said flywheel, said input means rotatable with respect to said support means;
- output means for transmitting rotary motion from said clutch brake unit to said press shaft;
- selectively operable clutch means for transmitting rotary motion from said input means to said output means;
- selectively operable brake means for applying a braking action to said output means to inhibit rotary motion of said press shaft, said brake means including a plurality of interleaved friction disks;
- a slidable actuator plate located between said clutch means and said brake means, the operative sliding of said actuator plate selectively actuating one of said brake means and said clutch means; and
- at least one hydrostatic fluid bearing each disposed at a respective side of said actuator Plate in facing opposition to at least one of said clutch means and said brake means.
