Abstract:
The purpose of this study was to determine the effect of
misalignment distance of Cooling Tower drive shaft on normal
stress and shear stress. Tensions that occur on the shaft
continuously for a long time cause the shaft to experience fatigue.
The greater misalignment distance will not only damage the shaft
but can damage other components. For this reason, the
misalignment of the cooling tower shaft is very important to study.
This study uses a simulation method by first making a design
drawing of the cooling tower drive shaft. Determine the material of
the shaft and coupling, then perform simulations and analyze the
results. The results of the Von Misses test at the highest and lowest
voltages did not show a significant difference this was caused by
the voltage difference that was not too far away. The shaft bears
varying loads, causing stress along the shaft which results in rapid
fatigue. These characteristics are associated with increased load
and all indicate that misalignment reduces the life and reliability of
the motor and its components. Based on the results of the Von
Misses test and the lowest risk displacement that occurs to the
effect of this misalignment is the misalignment distance (md = 1
mm), the higher the md value, the greater the risk that occurs to the
cooling tower drive shaft.
