Abstract
A duplex toothed chain includes a drive toothing that defines a drive toothing pitch circle, a driven toothing that defines a driven toothing pitch circle, toothed links, and joint links. The toothed links define joint apertures that are spaced at intervals from one another in a longitudinal direction and that are configured to receive the joint links. The joint apertures define a joint aperture pitch circle extending in the longitudinal extent of the duplex toothed chain. The driven toothing pitch circle is different from the joint aperture pitch circle and is arranged radially further distant from the joint aperture pitch circle than the drive toothing pitch circle is arranged radially distant from the joint aperture pitch circle. The differences in the toothing pitch circles increase the engagement efficiency.
