摘要： The invention relates to a toothed belt (10a, 10b) with two mutually oppositely arranged running surfaces (2, 4), wherein, on the running surfaces (2, 4), there are arranged toothings (12, 14) arranged obliquely with respect to the axial direction (X), wherein the obliquity is defined in each case by helix angles (16, 18) between the axial direction (X) and the direction of the tooth flanks of the respective toothings (12, 14). It is provided that the helix angle (16) of the first toothing (12) is oriented oppositely to the helix angle (18) of the second toothing (14).

摘要： A helically toothed drive belt made of elastomeric material having internal tensile cords made of aramid fibers, which tensile cords are arranged in the longitudinal direction of the drive belt, wherein the tensile cords each have two strands made of aramid fibers, wherein each of the strands has a twist and the strands are also twisted around one another to form the tensile cord, and the outside diameter of the tensile cord is less than 0.5 mm.
