Optimization of open gear design for dryer paper machine transmission system

摘要

In this research, design optimization of the dryer paper machine gear (driven gear) is performed by adding a stress-relieving hole feature. The aim of this research is to find the effect of hole features with a specific position and diameter size in reducing the value of stress that occurs so that the lifetime of the gear will increase. Design optimization begins with finding problem data that occurs in work field and continues with the analysis by mathematical calculations and software simulation by using Autodesk Inventor 2017 education version to find stress distribution that occurs on the gear with the current operating load used. From the analysis carried out on the gear in operational working conditions, the maximum stress value occurs on the fillet radius area with 22.7 MPa. With the addition of a stress-relieving hole feature in the area around the fillet radius, the optimal stress reduction was obtained by 7.05% to 21.08 MPa.
