Spur Gear, Pressure Angle 20°, Module 1.5, Shape A
A spur gear transmits motion between parallel shafts, and the module and tooth count together fix the pitch circle, so a pair meshes at the ratio of their tooth counts. Bore type decides whether the gear runs free on a shaft, keys onto it or carries a tapped hole for a set screw. Pressure angle 20 degrees is the standard profile for general power transmission.
