A 20 degree pressure angle allows for a smaller gear with less teeth before they begin to undercut making the base thinner than the pitch circle thickness of the tooth.
The pitch circle of a gear is very important as it is used by engineers to determine the shape of the teeth and the ratio between gears (ratios will be explained later).The pitch of a gear is the distance between any point on one tooth and the same point on the next tooth.The root is the bottom part of a gear wheel.he pitch point is the point where gear teeth actually make contact with each other as they rotate. Types of Gears Bevel gears can be used to change the direction of drive in a gear system by 90 degrees. A good example is seen as the main mechanism for a hand drill.
