| Shrnutí: | This paper presents a fatigue analysis of spur gears belong to speed reducers under radial and axial misalignment. The finite element method was employed to calculate the life cycles and the alternating stress in the spur gears. The misalignment was considered as a function of gear module, M. The radial misalignment was M0.2 and M0.5 and the axial misalignment was M0.2 and M0.3. The analyzed mechanism corresponds to the pinon and gear of the first stage of an all-terrain vehicle speed reducer. In both misalignment conditions, the maximum reduction of life cycles occurs in pinion gear due to high alternating stresses as torque increases. Changes in the contact zone due to gear misalignment cause stress concentrations in the face and root teeth. |
