铁路车辆所用窗框的重要特性是耐久和便于更换玻璃。日本国营铁路的NANIWA型标准窗框,可以满足上述要求。它是用轻合金的成型构件和成型橡胶件制成的。橡胶元件是一种最新设计。自1956年以来,这种形式的窗框已在日本国营铁路的所有新造和改造客车中采用,随后,又广泛应用在私营铁路的客车、出口车辆、公共汽车、摩托车和船舶上。这种窗框的应用正在迅速增长。为了简化结构和降低成本,轻合金窗框用闪光对焊组成。此外,还利用了铝合金的抗腐
Important features of window frames used in railway vehicles are durability and easy glass replacement. The NANIWA standard window frame of the Japanese state-owned railway line can meet the above requirements. It is made of a light alloy molded part and a molded rubber part. Rubber components is a new design. Since 1956, this form of window frame has been adopted in all new and remodeled passenger cars on the Japanese state-owned railroad and has since been widely used on passenger cars, export vehicles, buses, motorcycles and ships on private railways. The use of such window frames is rapidly growing. In order to simplify the structure and reduce costs, light alloy window frames with flash butt welding. In addition, the use of aluminum alloy corrosion
