Abstract

The invention relates to a device for clamping crankshafts during the hardening of the bearing surfaces, comprising two clamping heads, which are situated opposite to one another at a distance and of which at least one can be displaced to receive the crankshaft, and a fixed central support. The invention is characterised in that both clamping heads (1, 2) are coupled to the crankshaft (3) clamped by them so that they move in common. <IMAGE>
