Le dentature degli ingranaggi sono concepite in conformità alle più recenti norme DIN e ISO e ottimizzate per garantire la migliore portata sui fianchi e sulle basi dei denti. Le ruote con dentatura esterna sono cementate e rettificate mentre le corone dentate a dentatura interna sono bonificate e nitrurate.

Pinion tooth flank Meshed tooth flanks

Standard tooth flank

When the output pinion is under load, the shaft and tooth are
deformed. This deformation can lead to meshing interference and
edge wear.

Meshing interference and edge wear

// With ZOLLERN optimization
The pairing of output pinion and ring gear is calculated depending on the specific application. Shaft deformation and deflection of theoutput pinion are considered under load

Asymmetric crowning

In order to compensate for shaft deformation and deflection, the tooth flank is corrected with asymmetric crowning in the angle of the flank, appropriate to the torque. This prevents edge wear and ensures optimum load distribution.  

Tip relief

In addition, the tooth deformation under load is calculated and the tooth flank is corrected by means of tip relief. This prevents the ring gear from meshing too early.  

ZOLLERN optimization

Using tooth flank corrections, crowning and tip relief significantly increases the service life of the output pinion and ring gear. Significantly narrower tooth crown widths can be used.
