Dealing with carburize case hardened gear distortion and growthis a challenge for the global gear industry. Attempts started in1978 with computer programs to calculate distortion and growth,plus residual stress distributions for a gear and evolved bygathering distortion data for a wide range of sizes, shapes,grinding allowances with trends for different geometries. A spreadsheet program with gear dimensional input, calculates thedistortions and growths, and then calculates the modifieddimensions for required protuberance and theminimum carburized casedepth. Case histories illustrate the consequences of variousgeometries and future developments are discussed.
