The Effect of Keyway Geometry Ratio of Shaft Against Fatigue Failure
Abstract
Fatigue is one of the causes of damage for a shaft. Fatigue cannot be predicted, it can happen suddenly. Therefore need further improvement about fatigue causes. In previous studies, many researchers have made improvements for material commonly used as a shaft to increase the strength of fatigue, but there’s still a little bit of research that discusses the surface design of the shaft. The purpose of this research is to study the effect of the ratio of the keyway geometry against fatigue by looking at the ratio between the width and depth of the keyway. The method is a simulation method with SolidWorks. The fatigue simulation typed use is rotary bending with ASTM E466 standard. The keyway ratio variants are 3:1 mm, 3:2 mm, and 3:3 mm with each load are 40%, 50%, 60%, 70%, and 80% from ultimate tensile strength material. The results in a 40% load, variants 1,2,3 reach more than 1.000.000 cycles until broken. 50% loading as the same as 40% loading. Until 60% load, variant 1 still reaches 1.000.000 cycles, variant 2 gets 402.699 cycles, variant 3 gets 317.727 cycles until the material is damaged. 70% load, variant 1 gets 641.211 cycles, variant 2 gets 201348 cycles, variant 3 gets 166.116 cycles until the material is damaged. 80% load, variant 1 gets 311.218 cycles, variant 2 gets 123.921 cycles, variant 3 gets 102.371 cycles until the material is damaged. With the same broken position on each round groove keyway.
