Jet Engine Basic Component: Involute Spline

Shaft of the jet engine rotate at high speeds and slide in the axial direction due to temperature differences.When connecting rotating shafts, a structure is required that can maintain the rotation axis even when the torque changes and when it slide.To achieve this goal, "Involute Spline" with teeth that have an involute curve similar to that of gears are used.A pressure angle of 20° is common for gears, but 30° is common for splines, and the tooth height is about half that.The main portion whe…
