WebVandaag · The standard gear tooth form is identified as the 20° involute spur. At one time, 14-1/2° involute spur gears were common but this is no longer so. These latter degree identifications refer to the pressure angle of the tooth, the line of contact the two teeth follow as they come into and out of mesh. Web17 feb. 2024 · Base circle diameter (db) is the circle used to form the involute section of the gear tooth. Pressure angle (α) is the angle between the tangent to the tooth profile in an axial plane at the pitch surface and a line perpendicular to the axis. It’s usually α = 20° [5].

WebThe involute system was invented before generating machines were available. The old method of cutting in-volute teeth with a formed cutter demanded close adher-ence to the pitch-diameter for which the cutter was made in order to reproduce the desired tooth-form. The gear books of that time emphasized the maintaining of the pitch-diameter.
