WebIf the pitch diameter is D = m.N where N is the number of teeth and m is the modulus (for metric gears), then the base circle diameter for a pressure angle α, most usually 20 degrees, is D.cos α and the root diameter is given by the amount the tooth falls below the pitch circle. This amount is the dedendum and is usually 1.25m. WebIt is the angle between the common normal to two gear teeth at the point of contact and the common tangent at the pitch point. It is usually denoted by φ.The standard pressure angles are 14.5° and 20°. Addendum. It is the …
