N2 - This paper discusses the influence of hardening pattern, material and residual stress conditions on the tooth root bending strength of gears with module 4 mm. Furthermore, correlations of material properties such as surface hardening depth, surface hardness and core hardness with the tooth root bending strength are discussed. For the investigated induction-hardened gears in unpeened condition, nominal stress numbers (bending) for material quality MQ according to ISO 6336–5 for induction hardened gears can be achieved. For shot blasted gears, a significant increase in the tooth root bending strength has been observed. Main influence parameter on the tooth root bending strength is the surface hardening depth. A minimum surface hardening depth of 0.25·mn should be reached. For lower surface hardening depths, a significant decrease in the tooth root bending strength has been observed. Furthermore a strong influence of the hardening pattern on the residual stress condition was detected.
