Connecting rod for converting linear motion of piston of internal combustion engine of motor car into rotational motion of crankshaft of engine, has rod bearing whose axial bearing surface comprises form surfaces differing from chamfer

摘要

The rod (10) has a connecting rod bearing for bearing on a crankshaft, which comprises an axial bearing with an axial bearing surface (11). The axial bearing surface of the connecting rod bearing comprises hydrodynamically effective form surfaces (12-23) differing from a chamfer. The form surfaces are formed as a ramp, where height and length of each form surface are 0.3 mm and 5 mm, respectively. An angle of the ramp lies between 0.1 and 0.5 angular minutes. The connecting rod bearing comprises a rolling bearing (24) that includes multiple rolling elements (25).
