    摘要： In a link rod manufacturing method, a bracket material (14) having a ring portion and a mounting projection (15) is made by extrusion molding a material at the length corresponding to a plurality of brackets. On a forward end of the mounting projection (15), an engaging projection (17) with upper and lower steps (7a, 7a) is formed. An arm (2) is made by extrusion molding and regular-size cutting a material in a substantially I-shaped configuration which has a pair of first and second walls (20, 21) parallel extending on upper and lower sides and a third wall (22) crossing at a right angle and connecting these walls. A notch (23) is formed on an end of the third wall (22). When the engaging projection (17) is engaged with the notch (23), each of ends of the first and second walls (20, 21) on the side of ends 2a of the arm 2 is fitted onto the step (7a, 7a) and butted against a vertical wall (17b). Surfaces in the vicinity of butted portions (6) formed in this way forms a plane tool traveling surface and are supported on the insides thereof by the engaging projection (17) to prevent deformation. Therefore, the friction stir welding is carried out along the butt portion (6).

    摘要： The present invention relates to a connecting rod assembly (10) and method of manufacturing same. The method includes defining a small end (56) of a connecting rod having a terminal end (62) and defining a pin bore (64) extending through the small end. A pair of channels (68, 70) is forged on opposite sides (72, 74) of the small end (56), such that each of the channels is substantially perpendicular to the pin bore (64). A bushing (84) having a contact surface (90) including at least partially annular grooves (92, 94) and opposed distal ends is subsequently formed and installed into the pin bore (64) of the small end (56). Following installation of the bushing (84), the connecting rod is machined to reduce the width of the small end between each channel and the terminal end to where at least a portion of the grooves are disposed along the distal ends to reduce the need to deburr the area adjacent the pin bore.

    摘要： The invention relates to a camshaft wherein at least two finished individual cams are firmly placed onto a shaft in a defined angular position. The shaft can especially comprises an outer shaft and an inner shaft concentrically arranged inside therein. The aim of the invention is to provide a method which eliminates the need for a secondary treatment of the assembled camshaft. According to the inventive method of production, the following steps are carried out in chronological order: the at least two cams (1, 2, 4) to be firmly placed onto the shaft are detachably combined to give a manufacture module before placement, the first cams (1, 2) which are immobile with respect to each other on the finished camshaft being aligned in a relation to each other which corresponds to the final arrangement on the shaft; within the manufacture module at least the cam contours of the at least two cams (1, 2, 4) are finished on their radial peripheral surface; the finished cams (1, 2, 4) within the manufacture module are placed onto the shaft in a horizontal position; the first cams (1, 2) which are immobile with respect to each other on the finished camshaft are firmly linked with the shaft in the relation to each other with respect to at least their angular position determined in the manufacture module; the detachable combination of the cams (1, 2, 4) within the manufacture module is released and positioning and/or connecting auxiliaries (3, 5) which have been optionally used are removed.
