Improvement of Structure to Prevent Water Infiltration and oil leakage for Reduction Units of KTX

KTX is being operated on Kyung-Pu High Speed Railroad Line and Ho-Nam Railroad Line from April 2004. Reduction units is occurring water infiltration at heavy snow and oil leakage because of labyrinth structure. This paper describes design method and evaluation technology to improve structure to prevent water infiltration and oil leakage for reduction units of KTX. This reduction units need high power and high speed to run and they have to make optimal lubricant without change current interface.
