Traction mechanism with internal toothing and external toothing and transmission with traction mechanism

Abstract

Toothed belt with an internal toothing and an external toothing and transmission with such a toothed belt. Tooth crests of the internal toothing comprise a rounded region with a cross section in the shape of a segment of a circle, and tooth crests of the external toothing comprise a rounded region with a cross section in the shape of a segment of a circle. A region between two adjacent tooth crests of the internal toothing is at least as wide as a tooth width of teeth of the internal toothing, and a region between two adjacent tooth crests of the external toothing is at least as wide as a tooth width of teeth of the external toothing.
