Document Summary
Bigger gear is called the gear, and smaller is called pinion. For this example, green is gear and red is pinion. Linear speed at any point of rotating body is equal to angular velocity times the distance from axis of rotation to point. Linear velocity of red peg is what determines the green peg"s speed. The red pegs are moving at the angular velocity of the pinion times the radius of the pinion. Since the red and green pegs are essentially the same, but the radii are different so we end up with different angular velocities. the angular velocity of the pinion is higher, since the radius is smaller. Face width, b width of teeth. Circular pitch arc length spacing between teeth. 40p at the very top of this gear means pitch of 40. Internal gear & pinion teeth are inside of curvature of the radius of the gear.
