摘要：
Considering the residual stress of tooth surface produced by carburizing, tooth grinding and shot peening, the complex stress field of tooth surface contact stress and residual stress is established, and a method for calculating contact fatigue crack initiation and propagation life of spiral bevel gears is proposed. A gear finite element contact analysis model is established to calculate the multi-axis alternating contact stress field. Considering the complexity of residual stress distribution of space spiral surface, the tooth surface with variable curvature is discretized into network nodes. The residual stress field of tooth surface is established by measuring the surface and sub-surface residual stress. Based on Dang Van criterion, a tooth surface crack initiation model is established. Considering the residual stress and crack closure effect, a model of tooth surface crack propagation is established, and the gear contact fatigue life under compound stress field is calculated. The results show that the spatial curvature of tooth surface affects the distribution of residual stress caused by shot peening, and the residual compressive stress in the central region is about 20% higher than that in the edge region. The crack initiation location and the fatigue life of the tooth surface are mainly determined by the contact stress, and the residual stress will affect the average stress. The crack propagation life accounts for about 10% of the whole life, which indicates the failure to rapid fracture of gear contact fatigue. The research can be an important reference in the design of long life and high reliability gear transmission. © 2022 Editorial Office of Chinese Journal of Mechanical Engineering.
