Abstract
Measuring device for measuring a rotationally symmetrical cavity in a workpiece has a base body for supporting on the workpiece, and a measuring head with a sensor for scanning the inner wall of the cavity. The measuring device has a shaft connected to the base body. Measuring head is movable relative to base body in the axial direction of the shaft and is rotatable about a rotational axis defined by the shaft. The shaft is configured as a hollow shaft, and accommodates a drive shaft rotationally drivable by a rotary drive apparatus. A distal end of the drive shaft is connected to the measuring head in a rotationally fixed manner. The shaft is situated on the base body and movable in the axial direction of the shaft by a slide bearing system. An axial drive apparatus moves the shaft relative to the base body.
