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： Toothed belt drive with a toothed belt and at least two toothed pulleys, wherein the toothed belt has at least one drive side provided with a toothed profile, the toothed belt wraps around the toothed pulleys over a partial area of their circumference and the teeth of the toothed belt meshingly engage in the tooth gaps of the toothed pulleys, wherein at least one of the toothings on the belt or pulley is formed as a series of tooth pitches varying along the circumference, wherein
the individual tooth pitches are designed to vary by up to a maximum of 5% relative to the mean tooth pitch on the belt or pulley, and
the absolute deviation of a varied tooth pitch from the mean tooth pitch on the belt or pulley is limited by the backlash of the toothing,
wherein the backlash ES results from the difference of the width eS of the tooth gaps of the respective toothed pulley and the width eR of the teeth of the toothed belt in the middle of the tooth height of the teeth of the toothed belt.-

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.
