摘要

The shaft (1) has stamped and bent parts made of metal sheet material, where the unbalanced shaft is secured on a support shaft (2). The stamped and bent parts (3, 4, 5) with a middle part (M) and side parts are designed in a U-shaped manner, where the side parts protrude in an angular manner. The stamped and bent parts (S) are fixed with lateral parts on the support shaft. The support shaft comprises a cylindrical tube and a drive pin formed at an end of the tube. Bearing rings are secured between the stamped and bent parts on the support shaft.
