Title: Study on the Tooth Micro-Geometry Optimization of Planetary Gear for Drive Reducer
Corresponding Author: Sung Ki Lyu
Abstract: A popular approach to optimize the performance of a gear transmission system is the modification of the gear tooth microgeometry, which includes the intentional removal of material from the gear teeth flanks, so that the shape is no longer a perfect involute. Such modifications compensate teeth deflections under load, and the resulting transmission error is minimized under a specific torque. Therefore, micro-geometry modifications can be applied on the involute (or profile) and lead of the gear teeth. In order to study the tooth micro-geometry optimization, this research selected a mass produced planetary gear type drive reducer as a prototype. The original design was modeled by a commercial software named Romax Designer, which analyzes and optimizes different types of gear power transmission systems. The series analysis results obtained reveal some anomalies that require modification. Based on the result, optimization and gear tooth modification were done to deal with the load distributions on gear tooth, gear durability problem, safety factor and bearing life problem. This thesis presents the outstanding performance improvement obtained after such optimization. …

Title: Determination of Equivalent Moment of Inertia of Flywheel for Inertial Endurance Test of Excavator Slewing System
Corresponding Author: Young-Jun Park
Abstract: This study determined the equivalent moment of inertia of the upper rotating body of an excavator, for the inertial endurance test of an excavator slewing system. The input speed and torque of the slewing reducer were measured by an excavator slewing test, and the equivalent moment of inertia of the upper rotating body of the excavator was calculated using iterative calculation. We developed a dynamic simulation model of the excavator slewing system, and validated the model by comparing it with the slewing test results. Using the validated model, we further developed a simulation model for the inertial endurance test, that considers the moment of inertia of the upper rotating body of an excavator. We concluded that the new dynamic model for the inertial endurance test of an excavator slewing system well exemplified the actual slewing test results. …
