摘要： A piston has a piston body with a pair of pin bosses having pin bores aligned along a central axis. The pin bores have bearing surfaces, wherein at least one recess extends axially across at least one of the bearing surfaces. A groove extends partially about the bearing surface circumference and is arranged in fluid communication with the recess. The recess and groove provide a lubrication feature to the pin bore, while the bearing surface has an uninterrupted portion for enhanced load carrying capacity.

摘要： The invention relates to a piston-pin boss (18) of a piston (6) for an internal combustion engine, comprising a piston-pin bore (1) for receiving a piston pin. To improve the passage of oil and to form an oil reservoir, the interior surface (2) of the bore comprises a transversal groove (5) that lies parallel to the longitudinal axis (3) of the piston-pin bore (1) and opens towards the exterior of the piston and an oil circulation groove (4) that intersects the transversal groove (5) and encircles the longitudinal axis (3).

摘要： A wrist pin for a heavy-duty piston assembly has a body with an axis of rotation and a generally cylindrical outer surface. The outer surface is adapted for pivotal connection to both a pair of laterally spaced pin bores and a small end of a connecting rod generally between the pin bores. The outer surface has a surface roughness equal to or less than 0.10μm. The outer surface has a Kurtosis value that is inversely proportional with the surface roughness such that a product of the Kurtosis value and the surface roughness is between about 0.301μm to 0.60μm. The outer surface has a skewness of about -1.0 to 0.0 and a lay angle relative to the axis of about 85 to 95 degrees.

摘要： A rocking journal bearing is provided in a piston coupling mechanism. The bearing includes a sleeve and a wristpin constructed with two sets of eccentrically-disposed bearing surfaces which alternate in accepting a compressive load during an operational cycle of the bearing. The sleeve includes a network of grooves to transport oil to the bearing surfaces. Lubricating oil flow through the bearing is minimized by limiting provision of pressurized oil from the wristpin to the network of grooves to portions of the cycle when one or the other of the sets of bearing surfaces receives the compressive load.
