Pressure angle is the leaning angle of a gear tooth, an element determining the tooth profile. Recently, the pressure angle (α) is usually set to 20° , however, 14.5° gears were prevalent. Fig.2.2 Normalized Tooth Profile of Reference

2. Pressure angle. The pressure angle is the angle at which the tooth inclines against the normal line to the pitch line. (Figure 4-3) Generally, a pressure angle of 20° is used. However, pressure angles of 14.5° or 17.5° are also sometimes used. The larger the pressure angle is, the dedendum becomes wider and strength improves. 1. Addendum 2.
In this gear design article will discuss on how to measure pressure angle of a gear and the different gear terminologies and equations related to it.
The pressure angle exists between the tooth profile and a radial line to its pitch point. In involute teeth , it is defined as the angle formed by the radial line and the line tangent to the profile at the pitch point.
The 14.5° Pressure Angle is a standard parameter used in gear design, manufacture and use. FOR 2 GEARS IN MESH THEY MUST HAVE THE SAME PRESSURE ANGLE and PIT...
The pressure angle of a spur gear, also referred to as the angle of obliquity, is the angle between the line of action (or the line along which the force is transmitted between meshing gears) and the line tangent to the pitch circle. It is a crucial factor in determining the shape and size of the gear teeth.
Feature. S model and L model are for the use of small and large pitch respectively. The pressure angle of these gauges are 14 1/2° and 20°.
