Abstract
The invention is related to a toothed chain with alternating inner and outer chain links each joined by means of a chain joint, wherein the inner chain links comprise at least one inner plate and at least two joint bushes running perpendicularly through the same, the outer chain links comprise at least two outer plates and at least two joint pins running perpendicularly through the same, and to form a chain joint, one joint pin of the outer chain link each extends through a joint bush of the inner chain link, and at least one inner plate of the inner chain link and/or at least one outer plate of the outer chain link is embodied as a toothed plate with each two teeth defined by an outer flank and an inner flank each. To provide a toothed chain having an improved service life and which can lead to a more advantageous embodiment of the complete chain drive, it is provided that an external flank angle given for the two external flanks of a toothed plate, is α≧65° and ≦75°, and a ratio Vbetween a pitch p of the toothed chain and the outer diameter dof the joint pins is ≦2.65.
