The invention relates to a rotary-table bearing assembly, including: a rotary-table bearing, which has an inner ring, an outer ring, and rolling elements arranged in one or more rows, which roll on the inner ring and on the outer ring; and in each case an assembly component having a clamping segment, to which assembly components the outer ring and the inner ring are connected. According to the invention, the clamping segment of at least one assembly component is designed radially elastic on the assembly component, and/or the outer ring and/or the inner ring has a radially elastic connecting segment, by which the particular ring is connected to the assembly component.

Rotary-table bearing assembly

A direct drive for a rotation machine, particularly for a container treatment machine, this drive including a fixed machine part () and a machine part () rotating around a vertical machine axis, wherein the rotating machine part () is rotationally connected to the fixed machine part () by a roller bearing () arranged between the two machine parts () and having an outer bearing ring (), an inner bearing ring () and a plurality of rolling elements rolling between said bearing rings (), and can be driven by a torque motor (). On the rotating machine part (), a plurality of magnets () is provided, surrounding the rotating machine part, while on the fixed machine part (), a stator () formed of a plurality of electric coils () is arranged, such that the rotating machine part () can be set in a defined rotational motion through an electromagnetic field generated when the stator () is energized in cooperation with the magnets (). The stator () on the fixed machine part () is formed as a full ring of 360&#xb0; covering, without gaps, all magnets () on the rotating machine part (), this full ring being composed of a number of stator ring segments () adjacent to one another and connected to one another by an electrical series connection and also composed of a number of stop elements () arranged between the stator ring segments () for fixing the stator ring segments () in a circumferential and radial direction.

A device for receiving a workpiece for a workpiece carrier circulation system of a production machine is provided, including a workpiece carrier with a workpiece receiver and a holder to be arranged on the machine for receiving the workpiece carrier in a detachable, temporary manner. The workpiece carrier includes a rotor section () which, when the workpiece carrier is received in the holder, interacts with a stator () provided on the holder, forming a torque motor and thus being rotatable about an axis in the holder.
