<p>A clamping assembly (10) adjustable from a first position with a first stack height to a second position with a second stack height less than the first stack height, whereby said clamping force is substantially released, said clamping assembly (10) comprising: a flange nut (70); a clamp flange (20) connected to the flange nut (70); a thrust plate (50) having a plurality of axial penetrations (52) and rotatably mounted between the flange nut (70) and clamp flange (20); a first roller cage (30) having a plurality of penetrations (32); a first plurality of rolling elements (42) rotatably mounted in the penetrations (32) of the first roller cage (30); a second roller cage (60) having a plurality of penetrations (62); a second plurality of rolling elements (44) rotatably mounted in the penetrations (62) of the second roller (60) cage; a ring collar (80) having rotatably mounted between the clamp flange (20) and the flange nut (70) and surrounding and rotationally engageable to the thrust plate (50), whereby rotation of the ring collar (80) rotates the thrust plate (50) relative to the first (30) and second (60) roller cages from the first position with the first stack height, wherein the first and second roller elements (42,44) contact the axial surface of the center thrust plate (50), to the second position, wherein the first and second rolling elements (42,44) have entered the axial penetrations (52) in the thrust plate (50) and thus establish the second stack height. <IMAGE></p> |
