在我们国家(苏联)里,每年制造数千万个不同类型尺寸的齿轮。介绍国外制造齿轮的经验无疑地能引起工艺师们和生产者们的实际兴趣。 在这篇短文中只叙述外齿圆柱齿轮的机械加工方法;以塑性变形的方法得到轮齿的问题则不予考虑。 坯件的制造。钢质齿轮的坯件是锻件和标准的棒料。 In our country (the Soviet Union), tens of millions of gears of different types and sizes are manufactured every year. The introduction of foreign experience in the manufacture of gears undoubtedly aroused the practical interest of craftsmen and producers. In this essay, only the machining method of the externally toothed spur gear is described; the problem of obtaining the gear teeth by the method of plastic deformation is not considered. Manufacture of blanks. Steel gear blanks are forgings and standard bars.
