How to measure gear pressure angle
WebHow to Measure the Pressure Angle of a Physical Spur Gear Pressure Angle (): If you can draw a common normal line to the meshing teeth surfaces at the contact point between the meshed teeth and a tangent plane common to the pitch circles of both the gear then angle between the common normal line and the tangent plane is called pressure angle. WebCalculate the key dimensions for your external spur gear. Input the gear's tooth count, pitch (or module), and pressure angle to calculate the pitch diameter, root diameter, and outer diameter. This also generates the tooth dimensions: addendum, dedendum, working depth, and whole depth. The default Manufacturing Profile Shift Coefficient is 0.
