ABSTRACT:
Grinding machine for pins of heavy crankshafts on which the crankshaft is eccentrically mounted in a rotatable clamping arrangement on both sides, where the crankshaft pin to be ground is located in the rotational center of the clamping arrangement and on which the pin can be ground with a grinding head of a cylindrical grinder, with at least one relief arrangement for the crankshaft to supply an eccentrically rotating main bearing with constant, vertically applied force counteracting the dead weight of the crankshaft. The relief arrangement exhibits at least one relief bow for mounting of the main bearing to be supported whose suspension point essentially rotates in a location vertically above the main bearing and synchronously with equal eccentricity as the main bearing.
