1958年6月,在日本东海道新干线开始筹建的初期,以日本铁道技术研究所为主,吸收了NSK等轴承公司参加,成立了高速列车滚子轴承研究小组,对新干线车辆使用的轴承,包括车辆轴箱和驱动齿轮箱轴承,进行了一系列的试验研究工作,成功地解决了适应时速200公里以上高速运行的问题。本文仅就其车辆轴箱的结构,试验研究和运用情况,作一简要介绍。一东海道新干线的运行速度200～210公 In June 1958, at the beginning of the establishment of the Tokaido Shinkansen in Japan, the Japan Railway Institute of Technology mainly absorbed NSK and other bearing companies to participate in the establishment of a research group of high-speed train roller bearings, and used bearings of Shinkansen vehicles , Including vehicle axleboxes and drive gearbox bearings, conducted a series of experimental studies and successfully solved the problem of adapting to high-speed operation over 200 kilometers per hour. This article only on the structure of its vehicle axlebox, experimental research and application, make a brief introduction. A Tokaido Shinkansen speed of 200 to 210 kilometers
