Abstract
A measuring apparatus checks crankshafts 6 and has a rotatable workpiece holder (4, 5), a first group of bifurcated measuring devices (12a, 12b, 12c, 12d) for measuring the main bearings of the crankshaft and a second group of bifurcated measuring devices (19a, 19b) for measuring the connecting-rod bearings. Each bifurcated measuring device of the second group has several measuring sensors and its own drives for moving the bifurcated measuring device in the plane perpendicular to the axis of the crankshaft. When the crankshaft 6 is rotated, each bifurcated measuring device of the second group is either controlled on desired paths in accordance with the stroke of the connecting-rod bearing or is following up the movement of the connecting-rod bearing according to the signals of the measuring sensors.
