Development of Double Helical Gear Driving Device of Improved Division type

Abstract

Double helical gear driving device was contrived newly to realize stable run and high reliability in place of conventional helical gear driving device, because the load on the driving device is increased by high-speed Shinkansen to 360km/h. Therefore we produced some double helical gear driving devices experimentally, and verified performances and long-term durability by some tests using rotation testing machines and the high-speed examination train (commonly known as FASTECH360 and ALFA-X) on main track, and could confirm that it was a good result. In this paper, we describe the summary and characteristics that became clear in the development of the double helical gear driving devices of division type.
