Based on the fixed-end beam calculation. Anticipates that the total circumferential force can only be carried by one tooth.
Allowable load
F all = π c min b w m μ≥ F t
where:
Safety factor
S = F all / F t
Bending factor
where:
σ Ab | allowable stress in bending (material property) | |
r b | speed bending factor (table value) | |
y b | shape bending factor (table value) |
Contact factor
where:
σ Ac | allowable stress in contact (material property) | |
r c | speed pressure factor (table value) | |
y c | shape pressure factor (table value) | |
| size factor |
