Abstract

Almost all machines used in industry involve mechanical components. Among the mechanical components that are involved in this study was gear. Problem in gear can increase the cost of maintenance and operation increased .So, this study try to predict the failure helical gear sets using wear debris analysis .Methods to predict failure of gear to be used are mathematical modeling and experiment methods. Mathematical modeling method used is based on BS ISO 6336-2 standards used to predict the lifespan of a gear to analyze theoretically. By using information from manufacturer, life of a helical gear will be determined.BS ISO 6336-2 calculation is based on the contact stress at the pitch point of the meshing gears, or at the inner point of single pair tooth contact. BS ISO 6336-2 also states the contact stress shall be less than it permissible stressed for preventing failure. In addition, this study also examines how the mechanism and wear on the helical phenomenon while operating through gear test rig experiment. The physical inspection is use to assertion the deterioration of helical gear during experiment. Through the calculation, the result to start pitting is after 46 hours after run the machine for 30kg applied load. In experiment, the gear start to have micro pitting defect after 12 hours run the gear test rig. The number of pitting defect was increase proportionally with time during experiment. The experiment result use to validate the result of the calculation using BS ISO 6336-2.
