Bei einer Schrägverzahnung kommt die Paarung zwischen schräg verzahntem Ritzel und Antriebsritzel des Drehantriebs nicht direkt auf seiner ganzen Breite in Berührung, sondern die belastete Zahnbreite steigt beim Weiterdrehen der betrachteten Räder langsam an, bis das Zahnpaar auf ganzer Breite trägt, und fällt beim Herausdrehen aus der Kontaktzone langsam wieder ab.In a preferred embodiment, the two pinions are helically toothed, whereby two or more teeth are always in contact simultaneously with helical gear pairs between the drive pinion of the rotary drive and dam with the rack meshing pinion. It can be less hard shocks during tooth engagement of the helical pinion - wherein the drive pinion of the rotary drive may also have a helical toothing - occur, which leads to lower vibrational excitations. The Zahnfluss- and Grübchentragfähigkeit can be made higher. In a helical gearing, the mating between helical pinion and drive pinion of the Rotary drive is not directly in contact over its entire width in contact, but the loaded tooth width increases slowly when turning the wheels considered until the pair of teeth on full width, and slowly falls off when unscrewing from the contact zone again.
In einer bevorzugten Ausführungsform sind die beiden Ritzel symmetrisch zum Drehantrieb angeordnet. Die beiden Ritzel sind zu einem Antriebsritzel des Drehantriebs symmetrisch bezüglich einer Mittelachse durch das Antriebsritzel, welche senkrecht zur Längsachse der Zahnstange steht.In a preferred embodiment, the two pinions are arranged symmetrically to the rotary drive. The two pinions are symmetrical to a drive pinion of the rotary drive with respect to a central axis through the drive pinion, which is perpendicular to the longitudinal axis of the rack.
