Abstract
In a crankcase for a piston machine having a bearing support structure for a crankshaft main bearing with a bearing base part integrally formed with the bearing support structure and a bearing cover mounted onto the bearing base part by bearing bolts extending into bolt mounting columns, the bearing support structure includes a transverse wall which extends between the crankcase walls, the bearing support base and the bearing base part and includes a rib structure of an increased wall thickness formed between the bearing base part and the bearing support base and having a recess in the area between the end of a mounting bolt bore in the bolt mounting column and the bearing support base providing for a force flux path which istributes the force flux evenly over the length of the threaded mounting bolt bore area.
