Abstract: Where a circumferential surface has to be ground on a workpiece and the workpiece is being rotated around an axis which is not concentric with the surface, both the grinding wheel axis and the workpiece rotation axis are displaced during the course of each workpiece revolution. The result is that the point of contact between the grinding wheel and workpiece surface always lies on a straight line.

Abstract: A method of supporting a workpiece having journal and eccentric regions, in a grinding machine for grinding the eccentric regions thereof, is described which involves mounting the workpiece in a headstock of the grinding machine, providing a coupling between the workpiece and a rotary drive mechanism for rotating the workpiece about its main axis and fitting around at least one remote journal region of the workpiece a pair of members which form a journal bearing complementary to the said region, and fixing the lower of the two members to the machine, thereby providing support for the workpiece at the said remote position. The method is particularly relevant to the grinding of crankpins of a crankshaft. A grinding machine for grinding the crankpins of a crankshaft workpiece comprises headstock means mounted on the machine bed, a grinding wheel mounted on a wheelhead assembly, drive means for moving the wheelhead towards and away from a workpiece when fitted to the headstock, drive means for rotating a workpiece when mounted in the headstock, and two part cradle means mounted in the machine at least one part of which presents at least an upwardly directed curved support surface for engaging the underside of a journal bearing region of a crankshaft workpiece when fitted to the headstock.

Abstract: For finishing round surface sections of very heavy workpieces, for example the main pin and crank pin of crankshafts (12) for marine diesel engines, the invention proposes that the finishing belt and the pressure bodies (76) over which it passes be mounted on a rotary support ring (52) driven by a motor (74), while the workpiece remains stationary in the direction of rotation during the finish machining. The support ring (52) and a rotationally fixed head frame (44) of the finish machining head (34) are each split along a vertical contact plane running through the axis of the support ring, so that one half (42) of the machining head can be moved away from the other half (40) to allow the workpiece section for machining to be inserted into and removed again from the machining head.

Abstract: A crankpin phase indexing apparatus for indexing a crankpin on an axis of a main spindle in a crankpin grinding machine, and a method therefor. The apparatus comprises a main spindle (22) having a chuck body (25), a phase rotating shaft (53) deviating from the axis of the main spindle, a coupling (63) detachably connecting the chuck body and the phase rotating shaft to each other, and a clamp (40) for restraining rotation of the phase rotating shaft. At the time of processing, the clamp is released and the coupling is placed in a connecting condition whereby the chuck body and the phase rotating shaft are unitarily rotated simultaneously with rotation of the main spindle. At the time of indexing, the clamp is actuated and the coupling is placed in a released condition whereby the chuck body is rotated about the main spindle relative to the phase rotating shaft in keeping with rotation of the main spindle. Accordingly, a crankshaft caught by the chuck body can be indexed to a predetermined phase while maintained in a position relative to the axis of the main spindle where it was prior to indexing.

Abstract: In a method of grinding a crankshaft component, the latter is engaged by a grinding wheel and ground until about 50 microns oversize. The wheelfeed is then arrested and gauging of diameter and eccentricity takes place over several revolutions and at a plurality of angular positions. This information is then computed and averaged by a programmable computer means to produce a control signal for finish grinding the component to size.

Abstract: An apparatus for checking the diameter of crankpins (18) of a crankshaft (34) in the course of the machining in a grinding machine comprises a first arm (9) rotating with respect to a support (5) arranged on the grinding-wheel slide (1) of the grinding machine, a second arm (12) rotating with respect to the first, a reference device (20) carried by the second arm and a measuring device (16, 17, 40-45) associated with a reference device. A guide device (21), fixed to the reference device (20), enables the apparatus to engage a crankpin, in the course of the orbital motion of the crankpin, and limit the displacements of the first arm and those of the second arm when a control device (28-30) displaces the apparatus to a rest position.
