Abstract

A bearing arrangement for the balance shafts for balancing second order inertia forces on an internal combustion engine, in which the balance shafts run parallel to the crankshaft on both longitudinal walls of the crankcase, and have the ends carrying the balance weights supported by means of journal bearings within the crankcase and having driven ends supported by means of roller bearings outside the crankcase in the region of a crankcase end wall.
