  • Q1. What is formula to calculate module in gears
  • Ans. 

    The formula to calculate module in gears is the ratio of pitch diameter to the number of teeth.

    • Module = Pitch Diameter / Number of Teeth

    • Module is a measure of the size of the teeth on a gear.

    • It is commonly used in gear design and manufacturing to ensure proper meshing of gears.

    • For example, if a gear has a pitch diameter of 40 mm and 20 teeth, the module would be 40 mm / 20 = 2 mm.
