Abstract

The present invention relates to a crankshaft and a method for making such a crankshaft. The crankshaft (1) comprises a journal (2) with a shell surface which extends round a first centreline (3), a crankpin (4) with a shell surface which extends round a second centreline (5), a web (6) which connects an end surface of the journal (2) to an end surface of the crankpin (4), and a recess (9) in the web (6). The recess ( has an extent close to a central portion (7a) of a transition region (7) between the web (6) and the crankpin (4) or between the web (6) and the journal (2). The central portion (7a) is intersected by a plane (8) which extends through said two axes (3, 5). The recess (9) is formed in a drop forging process in which the crankshaft's crankpin (4), journals (2) and webs (6) are also formed.
