Failure analysis of shield machine main thrust bearing ring  caused by soft belt defects

Abstract

Abstract: After conducting testing on a certain type of shield machine, it was discovered that the spindle bearing had failed. Upon disassembly, large spalling pits and metal fragments were found in the part of the bearing raceway. The bearing ring, made of 42CrMo alloy steel, had undergone induction quenching to harden its surface. Analysis of the failure was carried out through macroscopic inspection, composition analysis, microstructure observation, and hardness analysis. The results sholo that the high temperature generated by contact fatigue in the soft belt area of the shield bearing ring results in the formation of a WEL (white etching layer) on the surface. The peeling of this layer further leads to severe abrasive wear on the raceway surface. As the wear particles transfer with the rolling body, they cause dense indentation pits in the hardened area, with some of the particles becoming embedded in the soft belt area. The increase of raceway surface roughness significantly impedes the bearing's normal operation, and finally leading to the failure.

Key words: shield machine bearing, 42CrMo steel, contact fatigue, abrasive wear, failure analysis
