Abstract
AbstractThe total deformation and stress generation are taken into consideration because the more the stress is developed high chance of fatigue failure of gears while designing the gears. Gears fail due to many reasons, some are friction, crack generation, or some defect during manufacturing, all these ultimately lead to fatigue of gear. In this paper, the equivalent stress and total deformation are analyzed in three different gears, namely spur gears, bevel gears, and helical gears which are of structural steel. A comparative study has been done between these gears considering the same parameters. The selected gears have a 6 m module, 30 teeth in gear, and 15 teeth in pinion. Under the torque of 1715 Nm, the three gears are analyzed. From the results, the minimum deformation is experienced by the helical gears of value 0.000030062 m and maximum in case of bevel gears that is of 0.0013472 m. And in the case of stress analysis, the bevel gears show the maximum formation of stress near teeth 2.2088*e9 Pa which is nearly the same as in spur gears. The helical gears show the least stress formation among these three gears. So, better results are obtained for helical gears in both the analyzes.KeywordsANSYSSpur gearHelical gearBevel gearsFEASolidworks
