摘要： A universal offset connecting rod and method of manufacture of a universal offset connecting rod comprised of an offset connecting rod having an offset longitudinal axis, a first circular aperture used for pivotally attaching the offset connecting rod to a wrist pin, and a second circular aperture used to pivotally attach said offset connecting rod to a crankshaft, and a force transfer area creating an angle of offset which directs the line of action to a point away from the center of said second circular aperture. The force transfer area is a triangular area free from any solid material and defined by the normal line of action on one side and the offset connecting rod on the remaining two sides. The connecting rod is therefore discontinuous along the traditional line of action, resulting in a completely offset of transferred force.

摘要： Conventionally, in hot forging of a valve umbrella portion of a hollow engine valve, poor finish accuracy has been provided, and in cold forging thereof, materials which can be used have been restricted. In addition, in the cold forging and the known hot forging, the number of steps for drawing is increased, which requires a large number of steps for intermediate heating processes such as annealing, with the result that the poor workability has been obtained. In view of this, a semi-finished product having a hollow and an expansion diameter portion is manufactured in advance (first step), and a press device for folding an outer cylinder (4) and an inner cylinder (5) around an entire die set (DS) is used, thereby performing drawing with a body of the semi-finished product as the center in a constant temperature atmosphere at any temperature between a room temperature and 870° C.

摘要： A connecting rod and methods for making the same are disclosed. A method of making a connecting rod may include joining a first connecting rod blank and a second connecting rod blank together. The first connecting rod blank includes a first material, while the second connecting rod blank includes a second material different from the first material. The first and second connecting rod blanks have an interface between the piston pin and crankshaft ends. The method further includes narrowing a cross-section of the blanks at the interface, forming a piston pin aperture in the first connecting rod blank, and forming a crankshaft pin aperture in the second connecting rod blank. At least one of the narrowing and forming steps works a perimeter of the interface, thereby forming a generally smooth connecting rod surface about the perimeter of the interface.

摘要： A method of manufacturing a connecting rod assembly including the steps of defining a small end of a connecting rod assembly having a terminal end and then defining a pin bore extending through the small end of the connecting rod assembly. A pair of channels is formed on opposite sides of the small end of the connecting rod assembly wherein the axis of each of the channels is substantially perpendicular to the axis of the pin bore. A bushing having a contact surface including at least partially annular grooves disposed thereon is installed into the pin bore of the small end. The connecting rod is then machined to reduce the width of the small end between each channel and the terminal end wherein at least a portion of the grooves are disposed along the distal ends to reduce the need to deburr the area adjacent to the pin bore.

摘要： A connecting rod assembly includes a first end and a second end having bore extending therethrough and adapted to be aligned with a piston pin bore and receive a piston pin. The second end further includes a terminal end and has a reduced width configuration. The reduced width configuration is formed by machining a pair of channels that are formed on opposite sides of the second end between each channel and the terminal end. The bushing includes at least partially annular grooves disposed on the contact surface along at least a portion of opposed distal ends, where the grooves substantially eliminate the need for the small end to undergo a deburring process after the second end is machined to provide a reduced width configuration.

摘要： A connecting rod is formed by cold forging in a single pressing cycle at a good accuracy without separately preparing a large-end cap, to thereby reduce the manufacturing cost. A double-action type of forging apparatus is made up of an upper die, a lower die, and a large-end portion punch and a small-end portion punch, both being movably provided in each of the dies. The upper die is closed to the lower die while forging a preform, to thereby roughly form a connecting rod. Then, the large-end portion punch and the small-end portion punch are protruded into a forming space between both the upper and lower dies to forge the parts to be pierced, thereby filling underfilled parts with material. Then, the large-end portion punch and the small-end portion punch on the side of the upper die are pushed out of the forming space to reach the lower die. The underfills left in the parts to be pierced are blanked or punched away to form a large-end hole and a small-end hole.
