Palloid spiral bevel gears

1 Calculation of palloid spiral bevel gears in KISSsoft, including rough sizing procedure

1.1 Executive summary

In the palloid spiral bevel gear, the normal module is constant over the whole face width due to the involute shape of the gear in its width direction (of course, the profile is also involute). Therefore, using the transverse module on the inner and outer diameter mte and mti respectively, the true helix angles on the outside and inside can be calculated. The values can then be used for a more precise rating in KISSsoft.

Below, the rating and rough sizing of a palloid spiral bevel gear in KISSsoft is shown.
