Strength calculations for meshing gears and worm gears
Gears: determining tooth loads and strength calculations

Standardization

The general method for calculating the teeth of meshing gears is the subject of the following ISO documents.

ISO 10300 – part 1. Basic principles, introduction and general influencing factors ;

10300 – part 2. Calculation of surface pressure resistance ;

10300 – part 3. Calculation of bending strength at tooth root.

Please also refer to the detailed instructions supplied by the main production machine manufacturers: Gleason, Oerlikon, Klingelnberg.

Basic rules

The ISO documents bring us back to the problem of parallel...
