TOOTHED BELT COMPRISING RUNNING SURFACES PROVIDED ON OPPOSITE SIDES AND HAVING TOOTH SYSTEMS, THE HELIX ANGLES OF THE TOOTH SYSTEMS BEING ORIENTED IN OPPOSITE DIRECTIONS, AND ASSOCIATED TOOTHED BELT GEAR

摘要

The invention relates to a toothed belt (10a, 10b) comprising two running surfaces (2, 4) on opposite sides, wherein tooth systems (12, 14) oriented obliquely to the axial direction (X) are provided on the running surfaces (2, 4), the cant of each system being defined by helix angles (16, 18) respectively between the axial direction (X) and the direction of the tooth flanks of each tooth system (12, 14). According to the invention, the helix angle (16) of the first tooth system (12) is oriented in the opposite direction to the helix angle (18) of the second tooth system (14).
