一、前言万向轴是液力传动内燃机车驱动装置的重要元件之一,用以传递从发动机到车轴间一系列传动的牵引扭矩。它是在大扭矩和高速转动的情况下工作的。过去,一直使用40Cr 钢自由锻造的制造工艺。这种工艺不但成本高,材料的有效利用率低,生产周期长,而且还影响生产的发展。大功率高速液力传动内燃机车万向轴采用球墨铸铁,在国内外还没有先例,那些只相信洋人而不相信自己的权威人士胡说什么:“万向轴采用球墨铸铁,这简直不懂得选材。”但我们并没
I. INTRODUCTION The universal shaft is one of the most important components of the hydrostatic drive locomotive drive system for transmitting the traction torque of a series of transmissions from the engine to the axle. It works with high torque and high speed rotation. In the past, 40Cr steel has been used for free forging manufacturing process. This process is not only costly, the effective utilization of materials is low, the production cycle is long, but also affect the development of production. High-power high-speed hydraulic drive diesel locomotive universal shaft with ductile iron, there is no precedent at home and abroad, those who believe only foreigners do not believe what their nonsense nonsense: “Cardan shafts with ductile iron, which simply do not know how to choose. ”But we did not
