Abstract

The design overcomes the difficulties of roller bearings where lubrication is complicated and achieving accurate fitting is difficult. Damage can also occur with frequent starting during cold winters. The crankshaft fits in a continuous tunnel housing. The ring or disc is built onto the arms of the crankshaft sections, and serves as the outer liner or cover for the journal of the friction bearing. Its diameter is greater than the maximum diameter of the crankshaft. The bearing shell is cast in the housing. It has a groove with at least two radial lubrication orifices. The bearing shells are located together by a peg. The outer diameter of the ring is between 5.1 and 6.0 times the width of the bearing.
