Step 1

The base circle diameter \(d_b\) is given by: \[ d_b = d \cdot \cos(\phi) \] where \(d\) is the pitch circle diameter and \(\phi\) is the pressure angle. For the pinion: \[ d_{b1} = 38.100 \cdot \cos(20^\circ) \] For the gear: \[ d_{b2} = 95.250 \cdot Show more…

Thanks for your feedback!

Pinion (Driver Gear) has 24 teeth and Gear (Driven Gear) has 60 teeth and a 20-degree pressure angle. Pinion pitch circle diameter = 38.100 mm, Pinion addendum circle diameter = 41.275 mm, Gear pitch circle diameter = 95.250 mm, Gear addendum circle diameter = 98.425 mm, Determine a) the length of action b) the contact ratio
