KTX-1 감속구동장치 성능 향상 방안 연구

초록

The running gear system of KTX-1 train is core equipment which operates the train. The running gear systems torque power which is generated from a traction motor to an axle gear of reduction unit. The vibration in the gear is caused by wear of gear, gear tooth breakage, surface fatigue, misalignment, poor assembling accuracy and resonance of parts. The vibration in the bearing is caused by damage of bearing, misalignment, cracks and denting. KTX-1 running gear systems has caused many problems, such as gear damage, leaving the intermediate gear, intermediate gear shaft breakage, breakage tripod connection bolts and axle gearbox oil leakage and excessive water inflow problem. This study was conducted to study the performance enhancement with the improvement of the main problems of KTX-1 running gear systems.
