ABSTRACT:
A support arrangement for a workpiece table of a gear testing machine which is mounted at a machine frame by means of an antifriction bearing arrangement to be rotatable about a vertical axis. Between the machine frame and the workpiece table there are arranged, coaxial with the antifrication bearing arrangemement, two support rings which can be rotated relative to one another between a rest position and a support position and vice versa. These support rings engage with one another by means of a number of pairs of complementary inclined surfaces which ascend opposite to the direction of rotation from the support position to the rest position and can be moved, by relative rotation, out of the rest position where they enable the workpiece table to rest upon the antifriction bearing arrangement, into the support position where they relieve the antifriction bearing arrangement from the load of the workpiece table.
