Gear Stress Calculation

Spur - Helical Gear Life. This app include Contact and Lewis Stress.

This app calculates the gear dimensions using the following parameters:

1.- Module

2.- Teeth Number

3.- Helix Angle

4.- Addendum Factor

5.- Pressure Angle

6.- Face Width

7.- Modified Center distance

The app will provide as a results parameters the main geometry of a pair of gears, the X-Profile requirements, the Contact Ratio and two different Stresses:

1.- Contact pressure.

2.- Basic Lewis stress is provided.

Also the calculated life based on the contact and bending stress is provided. Life calculation is an approximation for a pair of gears carburized with a surface hardness of 58-63 HRC and a steel material type SAE 8620 or similar
