The present invention relates to a method of manufacturing a power transmission chain comprising a plurality of power transmission links, which is designed to transmit power, such as mechanical power, between the chain links and which chain links are usually known as sprockets. The present invention relates, more particularly, to a method of manufacturing power transmission chains which is of a type comprising chain links which are secured to each other by means of rivets.
Such a power transmission chain is known from U.S. Pat. No. 4,200,401. The rivets in this known power transmission chain are all arranged in rows at regular distances from each other. This known chain is designed to transmit, for example, mechanical power, and the rivets are thus arranged at regular distances along the length of the chain. The rivets which are arranged in rows are each provided with a rectangular bore. It is further known that the rivets are manufactured of steel, and that when the bores are then provided with the link pin, the pin is made to engage the bores from the top side of the rivet and to form a conical depression around the bores. The two side walls of the depression are normally inclined in relation to the axis of the pin and form shoulders which extend along the lower side of the bore and are so designed that, when the pin is introduced into the bore, the shoulders will penetrate into the walls of the bore from above and behind the walls, and the pin is so designed that, when the pin is inserted into the bore, a small deformation will take place in the pin, which will result in that the shoulder will become conical in shape. The final shape of the pin which has been manufactured in the manner described above has essentially the shape of a piston, but there is, however, a thin central region or neck in the pin, which neck projects beyond the sides of the bore. The bore of the rivet is, of course, circular, and it has been determined that the cross-section of the pin is approximately equal to the area of the outer surface of the rivet. The known power transmission chain is relatively stiff.
When power transmission chains of the kind mentioned above are used, there is always a risk that the pins will not be securely anchored in the bores of the rivets, and that thus the pins will be unable to be359ba680
