Abstract

PURPOSE: To manufactur at low cost the connecting rod for the closed type motor- driven- compressor according to a simple manufacturing method, by cutting the metal strip into a breadth of the connecting rod, and by bending it with press or forging machine.
CONSTITUTION: The metal strip 1, being cut into a breadth of the connecting rod, is formed into a shape of halved connecting rod 2 by the press or forging machine, and is bent into bilateral symmetry centered at the middle point; hereby, the connecting rod 3 is formed. After that, the internal hole 4 for the piston side and the internal hole 5 for the crank pin side are worked by machining; and the contact portion A of the metal strip 1 is closely welded to the metal strip end B, and the contact portion A' is also closely welded to the metal strip end B'. Besides, the distance between the axes of the crank shaft and the piston pin can be freely settled by changing the length of the metal strip 1. In the mean time, referring to the oil groove of the connecting rod 3, the concave portion 6 for the oil groove is installed in the metal strip 1, and the connecting rod 3 is formed so as to bring this concave portion 6 to the inside against the bending direction. Accord ing to this method, the oil feed from the crank pin side to the piston pin side can be satisfactorily carried out.
