The Dependence of Gear Teeth Roughness on Gearing Parameters

Abstract

The method of calculating the roughness of gear teeth depending on the parameters of gear meshing of gears at rolling friction with slippage. A model for calculating the equilibrium roughness of the surface in the form of a truncated cone, made on the basis of a spherical roughness model. Methods of determining the technological roughness protrusion; calculation of the depth of implementation of the protrusion of equilibrium roughness in the surface of the counter body; assessment of the pattern of change in the roughness of the gear teeth depending on the meshing module, load in the meshing. A method of evaluating the change in the ratio of the actual and nominal contact area depending on the degree of relative slip between the teeth of the gears, changes in the actual contact area of the gear teeth depending on the meshing module of the gear.

Energy analysis of wear sliding friction units

“…When deforming real materials containing defects, the total value of specific energy absorbed by the deformed volume before fracture depends not only on the forces of interatomic bonds, but also on the energy available in the metal before deformation, whose value is determined by the initial structural state as well as by loading conditions that affect the degree of heterogeneity of energy saturation of individual metal volumes during deformation [18]. The initial internal energy density is essentially the mechanical energy stored in the metal in the form of residual stresses.…”
