Fundamental Law of Gearing
-Velocity ratio between gears must remain constant throughout meshing (teeth engagement)
Involute Tooth Profile (Shape)
-Tooth contact happens at Pitch Point, or intersection of the cylinders or Pitch Circles
As Before: v = w1 x r1 = w2 x r2 & w2 = w1 x (r1 /r2) & T1 x w1 = T2 x w2
Cylinder 1 or Pitch Circle 1
Cylinder 2 or Pitch Circle 2
