08-01-2018
Preliminary note
Introduction
1 Scope
2 Symbols
3 Basic relationships for the
proof of safety against fatigue
fracture and damage caused by crack
initiation, permanent deformation and
overload breakage
4 Stress concentration factors
5 Stress components and their
superposition
6 Determination of the tooth root
strength, dependent on the mean
stress
7 Methodical procedure in the
proof of load capacity
Annex A - Example
Annex B - Form factors Y[Fa], Y[Fad],
tip factor Y[FS] and stress
concentration factors YSab,
Y[SFt], Y[SMb] and Y[SZ] for
given tooth fillets
Annex C - Tooth root geometry, computational
equations of the notch parameters
Annex D - Determination of the bending
moment arms h[Fa], h[Fe] and
of the angles of force application
a[Fa], a[Fe]
