Abstract

A latching apparatus is provided for a bearing assembly in which at least three bearing rollers, each of which is supported in a rotating fashion on a bearing journal, are arranged rotationally symmetrical and lying in one plane and guide and support a bearing race between them. The bearing journals are arranged on a carrier device that is in turn supported in a rotating fashion on a central axle aligned with the axis of rotation of the bearing race, so that the bearing race and the carrier device can rotate at different RPMs. Such a bearing assembly on a rotating carrier is especially well-suited for a centrifuge, in which a separation chamber with a centrally secured line is to be driven in such a way that the tube does not become twisted. The latching apparatus has bearing journals (22) arranged eccentrically on pins (74) rotatably supported in the carrier device (36) and a gear system component (84, 86) that rotates or revolves at the same angular velocity as the carrier device (36) and engages the pins (74) in such a way that when the gear system component is turned, the pins engaged with the gear system component are turned at the same time relative to the carrier device.
