Toothed belts with running surfaces arranged opposite one another and provided with toothings, the helix angles of the toothings being oriented in opposite directions to one another and associated toothed belt transmission

摘要

The invention relates to a toothed belt (10a, 10b) with two treads (2, 4) arranged opposite one another, toothings (12, 14) oriented obliquely to the axial direction (X) being arranged on the treads (2, 4), wherein the bevel is defined in each case by the bevel angle (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 in the opposite direction to the helix angle (18) of the second toothing (14).
