Dynamical wear prediction along meshing path in mixed lubrication of spiral bevel gears

Abstract: Surfaces of gears under combined rolling and sliding motions may suffer a complicated wear process due to the transient time-varying effect along the meshing path. In this paper, a methodology for predicting the wear of tooth surfaces is developed for the spiral bevel gears. In the wear model, the machined surface roughness, mixed lubrication, friction, flash temperature and the dynamic behavior of gears are all considered. Tooth-Contact-Analysis (TCA) method is used to get the time-varying parameters of meshi… Show more

“…More information on time step processing can refer to the previous work. 22,31 The composite principal curvature radius is 20 mm in the x-direction and 1500 mm in the y-direction. The length of the roller is 10 mm, and the chamfer length is 0.5 mm.…”

“…21 In addition, Wang et al 22 presented a TEHL model of a spiral bevel gear, considering of the velocity vector and the surface roughness. Considering certain time-varying parameters along the meshing trace of a spiral bevel gear, the progressive mesh densification was introduced in the numerical calculation of a EHL model 23 and the behavior of dynamical wear, 24 friction, temperature, and contact fatigue 25 was subsequently discussed. Then, an EHL analysis of spiral bevel gears was conducted after considering the contact point migration due to the deformation under a load.…”

“…Pu and Wang 14 17 examined the effects of various speed directions on the lubrication state, and discovered the analysis of the contact area friction coefficient as well as temperature field distribution. Pei 18 , 19 predicted the wear of tooth surfaces for the spiral bevel gears, then proposed a transient mixed lubrication model and a two-dof-torsional dynamic model.…”
