ABSTRACT:
A drive mechanism for rotating a crankshaft in a machine tool for working on the crankshaft includes a disc rotatable about a horizontal axis coincident with the crankshaft axis, the disc having a radial slot to receive a throw of the crankshaft. An endless flexible drive belt extends around a greater part of the periphery of the disc except for an upper part of the disc periphery and around a drive device to rotate the disc and with it the crankshaft throw in the radial slot in the disc. The crankshaft can be inserted in and removed from the disc when the disc is orientated with the slot vertical and when rotated away from the vertical, the crankshaft throw is retained in the slot by reason of the endless drive belt extending over the slot.
