Patent ID: 10962347

Abstract:
A measuring system (15) includes a measuring arm receiving unit (18) mounted on the housing (49) or on an axial pin (30) connected to the housing (49) for conjoint rotation so as to be rotatable or pivotable about the axis of rotation (D). A measuring arm (16) can be arranged on the measuring arm receiving unit (18). A motor unit (24) generates a motor torque about the axis of rotation (D) on the measuring arm receiving unit (18). The measuring arm unit (18) is mounted by a ball bearing guide unit (39) to be rotatable about the axis of rotation (D) in the peripheral direction and displaceably along the axis of rotation (D) in the axial direction A. An axial position of the measuring arm unit (18) in the axial direction is defined with the aid of a magnetic axial bearing device (46) and is maintained during operation.
