本标准与BS436第一部分可同时使用。 BS436第一部分,主要涉及到的是对一般齿形的基本要求、径节、精度和精度检验程序要求等,都是英制的。本标准(即第二部分)也提供了类似的资料,但都是公制的。因此,这两个标准是从英制变为公制的过程中同时应用的。 与BS436第一部分一样,本部分也符合ISO的规定。一般来讲,基准齿条齿形与ISOR53《用于普通机械和重型机械的圆柱齿轮基准齿条》推荐标准的要求是相符合的,而模数是从ISO/R54《用于普通机械和重型机械的圆柱齿轮的模数和径节》中选出来的。精度要求是
This standard and the first part of BS436 can be used simultaneously. The first part of the BS436 mainly deals with the basic requirements of the general profile, diameter section, accuracy and accuracy of the inspection program requirements, are in English. This standard (that is, the second part) also provides similar information, but are metric. Therefore, these two standards are applied from the British system to the metric system. As with the first part of BS436, this part also comply with the provisions of ISO. In general, the reference rack tooth profile conforms to the ISOR 53 Recommended Standard for Cylindrical Gear Reference Racks for General Mechanical and Heavy Machinery, and the modulus is from ISO / R54 “for general machinery and heavy duty Mechanical cylindrical gear modulus and diameter ”selected. Accuracy requirements are
