ABSTRACT:
In a roller chain sprocket for a chain drive, the profile of each tooth comprises a proximal portion (AB), an intermediate portion (BC) and optionally a distal portion (CD). The proximal portion (AB) is shaped like an arc of a circle with a radius (r) at least as large as the radius (r.sub.r) of each roller of the chain. The intermediate portion (BC) has a complex curvature defined by mathematical equations, whereas the optional distal portion (CD) is shaped like an arc of a circle with a radius R, equal to the pitch minus the radius of the roller.
