Gear Stress Calculator
Introduction & Importance
Gear stress is a critical factor in the design and operation of mechanical systems. Our gear stress calculator helps you determine the stress on your gear teeth, ensuring safe and efficient operation.
How to Use This Calculator
- Enter the number of gear teeth.
- Enter the applied torque in Newton meters (Nm).
- Select the material of the gear.
- Click ‘Calculate’.
Formula & Methodology
The formula used to calculate gear stress is:
σ = 16 * T / (π * d * b * cos(β))
Where:
- σ is the stress in the gear tooth (in Pa)
- T is the applied torque (in Nm)
- d is the diameter of the pitch circle (in m)
- b is the width of the gear tooth (in m)
- β is the pressure angle (in degrees)
