Abstract

The residual stress profiles in speed gears for automotive vehicles were determined. The profiles were measured at the root between two teeth of the gears by x-ray tensometry without the necessity of cutting the pieces. The gears were cemented, quenched and annealed. After this heat treatment, compressive residual stresses were introduced by shot-peening. The profiles indicate the maximum residual stress of -950 MPa (compressive) at a depth of 0.05 mm. The stresses are zero at a depth of 0.25 mm. In the gears without shot-peening the maximum residual stress at the surface is -600 MPa (compressive) and is zero at a depth of 0.30 mm.
