Apparatus for rolling of crankshafts

摘要

An appliance consisting of at least one clamping chuck (10,11) for the crank shaft (6) applies tensile force (12) on the crank shaft in the crank shaft's lengthwise direction. The crank shaft is clamped between a clamping chuck, a tailstock or fixed stay. Additional bending stress is applied to the crank shaft by support rollers., while extra external stress is applied when the passes or radii are being rolled.
