How to Use

  1. Select gear type (spur, helical, or bevel) and input module (1.5–8 mm), number of teeth (12–120), and material (steel AISI 4340, aluminum 6061-T6, or cast iron).
  2. Define loading conditions: torque (5–500 Nm), speed (100–5000 rpm), and service factor (1.0–1.5 for industrial duty).
  3. Run contact stress analysis using Hertzian equations; simulator returns Hertzian contact stress, bending stress per ISO 6336, and safety factors against pitting and tooth breakage.
  4. Export stress contours and bearing load distributions for drivetrain assembly validation.

Worked Example

Helical gear pair: Module 3 mm, 30 teeth pinion meshing with 90-tooth gear, material steel (E = 210 GPa), input torque 75 Nm at 1200 rpm. Pressure angle 20°, helix angle 15°. Simulator calculates Hertzian contact stress = 1240 MPa, bending stress (AGMA) = 315 MPa. With allowable contact stress for steel = 1600 MPa, safety factor = 1.29. Bearing radial load on intermediate shaft = 8.2 kN; axial load = 1.1 kN from helix angle.
