Abstract
In a roller chain transmission, the diameter D of the rollers, the outer diameter d of the pins, and the height H of the inner plates satisfy the relationships 0.72P≦D≦0.79P, 0.40P≦d≦0.44P, and 0.96P≦H, with respect to the chain pitch P. The radius r of the arc of the tooth gap bottom of the sprocket teeth satisfies the relationship 0.505D≦r≦0.505D+0.069{square root over (D)}. The transmission chain exhibits high durability due to improved strength and wear resistance under high loads.
