为克服标准螺纹联结固有的缺陷,美国Detroit丝锥与工具公司发明了一种线接触螺纹联结,具有自动防松、各牙受力均匀、加工与装配方便等优点,西德和日本也已按许可证生产切削这种螺纹的丝锥和量规.这种新型螺纹的优越性已为实验和实际应用所证实,有可能导致标准螺纹根本性的变革.特别由于不再需要数量众多的防松零件,可使机器重量获得可观的减轻;而且特别适合于在铝、镁合金等轻金属上使用;所以,对航空产品可能起的作用就显得尤为重要.现根据国外杂志上的一些报导,对这种新型螺纹作一简要介绍和论述,希望引起我国航空工程界的注意和兴趣.一、标准螺纹联结的缺陷
In order to overcome the inherent defects of the standard thread connection, the United States Detroit taps and tools company invented a thread contact thread connection, with automatic anti-loose, uniform force of each tooth, processing and assembly advantages, West Germany and Japan have also been licensed The testers produce gauges and gauges for this type of threading.The superiority of this new type of threading has been demonstrated experimentally and in practice with the potential to cause fundamental changes to the standard thread, especially since a large number of loose parts are no longer required So that the weight of the machine to obtain considerable relief; and is particularly suitable for use on light metals such as aluminum, magnesium alloy, so the role of aerospace products may become more important.According to some foreign magazine reports, the new thread For a brief introduction and discussion, hoping to arouse the attention and interest of China’s aviation engineering community. First, the standard thread connection defects
