Development of double helical gear unit for Tokaido-Shinkansen achieving both reliability improvement and maintenance workload reduction

A failure in the Shinkansen bogie can result in a catastrophic accident, necessitating the minimization of failure risks through robust design and proper maintenance. Helical gears have been used in the gear units from the series 0 to the series N700 Shinkansen. This research focused on the gear units and...
