为了减轻重量、提高安全和可靠性,除提高预定的油耗量改善机械性能外,重点在于有效地改变未来直升飞机传动装置的设计。上述设计装置,用普通渗碳齿轮钢,有可能达不到技术要求的。因此,在传动装置的设计中,采用新近生产的一种回火稳定渗碳钢,尽可能地更好地改变表面覆盖层,可以提高其性能,但是应当说明,为了提高主要的性能,在材料和处理工艺两个方面,都必须有新的改变。本文研究称之为“二次硬化”新颖表面的工程技术,并且讨论实现这种技术的可能性和在高性能齿轮的加工工艺中的适应性。
In order to reduce weight, improve safety and reliability, in addition to improving the mechanical properties with a predetermined fuel consumption, the emphasis is on effectively changing the design of future helicopter transmissions. The above design device, with ordinary carburized gear steel, may not meet the technical requirements. Therefore, the use of a newly produced, tempered, stabilized carburized steel in the design of the transmission improves the surface coating as much as possible to improve its performance, but it should be noted that in order to improve the main properties, And dealing with the two aspects of technology, there must be new changes. This article examines engineering techniques called “secondary hardening” of novel surfaces and discusses the possibilities of implementing this technology and its adaptability in high-performance gear machining.
