<p>A chuck (1) for rotating around a rotation axis (X A ) a centrifugal separation bowl (2) secured thereto includes a vat-shaped body (11) for receiving a lower end portion (22) of the separation bowl (2) secured therein with a peripheral rim (28) of the chuck (1) surrounding an outer flank (23) of the separation bowl (2). The chuck includes a plurality of clutching systems to co-operate with the flank of the separation bowl (2) in securing it to the chuck (1). The clutching systems include a channel (30) formed in the chuck body (11) with an arcuate path in the peripheral rim (28) of the chuck body. A chain of translatory bodies (16, 17, 18, 19, 20) arranged within the channel (30) includes a proximal translatory body (16) and a distal translatory body (20) in the chain, whereby a force (15, 16, 21) acting on the proximal body (16) and directed outwardly of the rotation axis (X A ) is transmitted through the chain of translatory bodies to the distal translatory body (20) to urge it inwardly towards the rotation axis (X A ) to clutch the outer flank (23) of the separation bowl (2) whereby the separation bowl (2) is secured to the rotary chuck (1).</p> |
