Gear
GEAR Gear is disc with several teeth on their circumference. Varying torque/Speed, direction of movement is the function of gear and based on design and construction, its applications differs. DESIGN OF GEAR Assumptions Number of Teeth (N) = 25 Module (Standard)(m) = 10 Pressure angle = 20 ° CALCULATIONS Addendum = 10 Dedendum = 1.125 × 10 = 11.25 mm Pitch Circle Diameter (d) = m × N = 10 × 25 = 250 mm Outer diameter (OD) = PCD + (2 × addendum) = 250 + (2 ×10) = 270 mm Root or Inside diameter (Id) = PCD - (2 × dedendum) =250 – (2×11.25)= 227.5 mm Circular pitch = ( Ï€ × PCD)/N = (3.14×250)/25 = 31.4 Tooth thickness = Circular pitch/2 = 15.7 mm Youtube link : https://youtu.be/7QFFtkaTSxM Follow me on instagram: https://www.instagram.com/d
