ABSTRACT:
A two speed press drive using hydraulic actuated oil shear clutch/brake units is disclosed. The clutch/brake units for selecting high or low speed are in coaxial nested relationship to each other. The speed change is achieved using a planetary gear set in which all members of the planetary gear set are allowed to float thus providing exact tooth meshing for all components. The drive provides a more precise operation due to no wear of clutch plates and less heat generation in the clutch/brake units. The gearing and bearings for the unit are contained in a sealed chamber which is continuously supplied with oil which has been filtered and cooled.
