| Abstract: | Under the direction of theory of engagement, spur gear model with accurate tooth profile is set-up with 3-D mechanical design software (Solidworks) and large-scale engineering analysis software (ANSYS). Stress-strain distribution of sun gear, the weakest part in the oil-submerged planetary gear reducer, is analyzed. Effective calculation method was presented for the check of root bending fatigue strength and tooth surface contact fatigue strength, which gives a theoretical basis for the reliability optimization design of oil-submerged planetary gear reducer. |
