摘要： A wrist pin and method of reducing wear between members thereof, a piston, a connecting rod, and methods of construction thereof are provided. The wrist pin has a first portion extending between opposite ends configured for receipt in piston pin bores and a second portion extending between opposite ends configured for receipt in the pin bores. The second portion is configured for relative movement with the first portion. The piston includes a piston body having axially aligned pin bores, wherein at least one of the pin bores has a feature to prevent relative rotation of a wrist pin member. The connecting rod includes a connecting rod body having small end bore. The small end bore has a contour to allow relative rotation of a first wrist pin member therein and a feature to prevent relative rotation of a second wrist pin member therein.

摘要： A method for the production of a piston for an internal combustion engine is proposed, in which a piston blank (1) is forged, which is subsequently separated into two parts, to form an upper piston part (5) and a lower piston part (6), after which the lower piston part (6) and the upper piston part (5) are machined and then welded to one another again. Subsequently, the piston is finished. In order to simplify the production process and make it cheaper, during forging of the piston blank (1), the top (2) of the piston blank (1) is already partly given the shape of the underside of the upper piston part (5), and the underside of the piston blank (1) is given the shape that corresponds to the interior (3) of the lower piston part (6). Furthermore, after forging of the piston blank (1) and before separation of the upper piston part (5) from the lower piston part (6), the top (2) of the piston blank (1) is given the finished shape of the underside of the upper piston part (5) by means of a cutting machining method.

摘要： A die cast aluminum piston for a reciprocating compressor. The piston is cast with no coring and thus includes no aperture in the as-cast piston for a wrist pin. The aperture for the wrist pin is subsequently formed in the wrist pin in a preselected location after casting. The wrist pin is formed of a preselected diameter. Because the wrist pin can be placed in a preselected location with a preselected diameter, the same cast piston design can be used in a plurality of applications by varying the location of the aperture or the size of the aperture, or both.
