Abstract
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, andthe 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.
