以日本东海道铁路300系列动车用平行万向轴式驱动装置齿轮箱为例,叙述了其轻型化的现状和效果。驱动齿轮箱的主要减重措施是以AC4C铝合金铸造的齿轮箱体代替原用的铸钢箱体,仅此一项可减重约120kg。但箱体改用铝合金后,由于其热膨胀来数比铸钢大1倍,因而容易导致较大的热变形。针对这一问题,采取了抑制润滑油的温升措施。开发了润滑油量自动调节装置。使用这一装置后,不但有效地抑制了润滑油温升,而且可使驱动齿轮箱的耗油量减少20～50％。同时还介绍了实现轻型化的开发技术动向。
Taking Japan Tokaido 300 series railcar universal parallel shaft drive gearbox as an example, the present situation and effect of light weight reduction are described. The main driving gear box weight loss measures is to use AC4C aluminum alloy gear box instead of the original cast steel box, only one can weight loss of about 120kg. However, the use of aluminum alloy box, due to its thermal expansion to several times larger than the cast steel, which easily lead to greater thermal deformation. In response to this problem, take measures to suppress the temperature rise of lubricating oil. Developed a lubricant automatic adjustment device. The use of this device not only effectively suppresses the temperature rise of the lubricating oil, but also reduces the fuel consumption of the driving gearbox by 20 to 50%. Also introduced to achieve the development of lightweight technology trends.
