ている。Figures 1a and 1b show the state of contact between pins and bushings in a conventional roller chain. In particular, Figure 1b shows the state of contact between pins and bushings when the pins or bushings are worn and the contact area increases;
The figure shows a case in which a roller chain with a pin with an irregular cross section is used to create surface contact between the pin and the bushing, and Figure 3 shows a silent chain in which the hole in the link plate is modified to create surface contact between the pin and the hole. This represents the case where

Pin 1 of roller chain 1 and silent chain 2, etc.
1 and bush 12 or pin 21 and link plate 22
In the hole 23 shape, pin 11゜21 and bush 1
A chain characterized in that contact between the pin 11 and the bush 12, as well as between the pin 21 and the hole 23 of the link plate 22, is made into a surface contact by making the radius of curvature of the contact surfaces 11a and 21a of the hole 23 the same.
