In the formation of a crankshaft, such as used in small gasoline motors for lawn motors, chain saws and the like, separately produced crank webs, shaft pins and crank pins are used to form an integral crankshaft. Initially the various parts are shaped to the desired dimensions. The crank web can be stamped from a metal strip or it can be a forged sintered part. A shaft pin is inserted in sliding contact with an opening in a crank web and then the two parts are secured together by pressure welding. Another crank web and shaft pin are assembled in a similar manner. The two webs are then interconnected by a crankpin positioned in another opening in each of the webs and a connecting rod is installed on the crankpin. |
