Abstract
A crankshaft has a receiving platform for catching lubricant dropping from a main bearing assembly. The receiving platform has at least one wall disposed thereon. The wall has one point that is the furthest from the rotational axis of the crankshaft. One channel is defined in the platform and has an inlet disposed close to the point of the wall that is furthest from the rotational axis of the crankshaft. The channel has an outlet in the vicinity of a connecting rod bearing assembly, so that lubricant dropped on the receiving platform will flow to the connecting rod bearing assembly.
