Software for Cyclo-palloid Spiral Bevel Gear Calculation acc. Klingelnberg/DIN 3991

Copyright 1993-2017 by HEXAGON Software, Berlin


Calculation Base

ZAR2 calculates all dimensions of bevel gears with cyclo palloid gearing in accordance with Klingelnberg, and the safety margins against root fatigue fracture, pitting and scoring in accordance with DIN 3991.

Pre-dimensioning

In pre-dimensioning ZAR2 makes recommendations for the size of the bevel wheel, face width, modulus and number of teeth based on the axes angle, gear ratio, pinion speed and torque.

Calculation

The pre-dimensioning values can be used in the geometry calculation. The normal modulus can be calculated from the cutter modulus or reverse. The program also supports an angle correction if this is necessary, likewise the strength matching of pinion and disk gear via tooth thickness variation. ZAR2 calculates the minimum addendum modification for the pinion and the addendum modification factors for same specific sliding. All dimensions and contact ratios are calculated. ZAR2 determines the permissible deviations in accordance with DIN 3965 from the toothing quality.

Material Data Base

A data base is already included in the program containing the most important gearing materials and their values.

Strength Calculation

The safety margins against root fatigue fracture, pitting and seizure are determined in the strength calculation according to DIN 3991. The factors can be modified manually.

Tooth Forces

Axial and radial forces for push/pull operation are calculated. These values can be transfered to the shaft calculation programs WL1+.

CAD Interface

A scale drawing of the calculated bevel gears can be exported to CAD via the DXF or IGES interfaces.

Production Drawing

ZAR2 generates production drawings with ISO 7200 data field of bevel wheel and pinion, ready for printout or CAD.
