Abstract
A centrifuge includes an elastically supported centrifuge basket, a drive unit, and an endless drive arrangement, such as a drive belt arranged on a drive pulley of the drive unit and a driven pulley of the centrifuge basket support unit, for driving the centrifuge basket. A tension relieving device is provided for relieving or counteracting the tension forces of the endless drive arrangement. Thus the elastic supporting members of the centrifuge basket support unit are not stressed by the tension forces of the endless drive arrangement, and the tension relieving device can be pre-stressed so that the basket is in a neutral position during operation. For pre-stressing the tension relieving device, it includes an elastic thrust element, such as a compression spring packet, in addition to a length adjustable strut. To avoid tilting moments, the tension relieving device is arranged in a plane of the endless drive arrangement between the two pulleys.
