Therefore, the calculated tooth root stress of the unified expression principally differs from the one of the original standard. For this reason the actual stress here will be designated by the sign ”.Expressions (2.8) to (2.11) are rewritten in the same way as expressions (2.5) and (2.7), leading to the following unified expressions (Attachment 2.3.1):
Principally this standard is based on the work of Winter and Niemann [2.5]. In later years the equations have been further developed, finally leading to the DIN 3990 standard for helical gears [2.4]. On basis of this the definitive DIN 3991 standard for bevel gears has been issued in 1988. The equations in this standard are valid for so-called Null or V-Null gears, this means that the value of the profile modification factors or its sum is zero. Furthermore it is limited to bevel gears of which the virtual helical gears have a contact ratio less than 2. The material values have a failure probability of 1%.The variation of geo

因此，计算出齿根应力的统一表达主要的不同之处之一，原来的标准。由于这个原因，实际在这里强调将指定的迹象“ 。表达（ 2.8 ）至（ 2.11 ）是重写的同样方式表达（ 2.5 ）和（ 2.7 ） ，导致下面的统一表达（附2.3.1 ） ：
这个标准主要是工作的基础上冬季和尼曼[ 2.5 ] 。在随后几年的方程得到了进一步发展，最终导致了德国工业标准3990标准的斜齿轮[ 2.4 ] 。在此基础上最终标准3991标准锥齿轮已发出于1988年。方程，在此标准的有效期为所谓的零或V空齿轮，这意味着价值剖因素或其总和为零。此外，它仅限于锥齿轮的虚拟螺旋齿轮的接触率不到2 。这些材料的价值有一个失败的概率为1 ％ 。变化值几何以及实际负荷估计，制造和安装错误和润滑带来一些变化的结果。该因素对齿轮几何必须计算表达式的标准。负载因素来确定在四个不同的方式，即方法A ， B ， C和D的表现形式，该方法已被使用，将需要指出的一个指数。的准确性和计算的金额差异所有四种方法。的表达方法B已被用在这里。
这四个基本的表达方式是：
