Title: Device for preventing oil splash
Inventor: HONDA TSUTOMU
IPC: F02G1/053
Filed: 1991-12-20
Abstract: PURPOSE:To enable the amount of lubricating oil that enters a distance space to be controlled by circularly notching the end face portion of a crank pin. CONSTITUTION:As a cranckshaft 5 is rotated, a bearing surface is forcibly lubricated and lubricating oil caused to flow out of the bearing surface splases in particles inside a crankcase 1. Part of the splashing lubricating oil lubricates a cross-head 2. The lubricating oil is allowed to enter a distance space by the vertical motion of the cross-head 2, and may cause deterioration of engine performance when entering the actuation spaces of the above components. Therefore, a circular notched portion 10 is provided in the outer peripheral portion of the end face of a crank pin. In this case, even if the lubricating oil tends to splash because of centrifugal forces, the oil is allowed to flow along the circular surface and return into an oil reservoir while being almost attached to the surface by the oil viscosity, since corner portions on which the lubricating oil flows are circular. A splash of the oil can thus be restrained.
