本期封面所刊登图片是上海汽车传动轴厂生产的十字轴式万向联器。十字轴式万向联轴器(简称工业用传动轴)是汽车工业的主要基础件,也是七十年代初国外应用于重要机械中的基础件之一。这一新技术的出现和推广已有力地推动了国内外机械工业的发展。它对机械设备的技术改造和机械产品的更新换入,提供了有利条件。适用领域汽车工业、工程机械、起重运输机械、石化工机械、冶金设备主轴机、内燃机车主辅机、高低速船舶、国防军工航天,试验机械、轻重工业自动化等。
The picture published on the cover of this issue is the cross shaft universal joint produced by the Shanghai Automotive Driveshaft Factory. Cross-axis universal coupling (referred to as the industrial transmission shaft) is the main basic part of the automobile industry, and it is also one of the basic components used abroad in important machinery in the early 1970s. The emergence and promotion of this new technology has strongly promoted the development of the domestic and international machinery industry. It provides favorable conditions for the technical transformation of mechanical equipment and the replacement of mechanical products. Applicable fields Automotive industry, construction machinery, lifting and transporting machinery, stone chemical machinery, metallurgical equipment spindle machine, diesel locomotive main and auxiliary engine, high and low speed ships, national defense military space, test machinery, light and heavy industrial automation, etc.
