摘要: 本文运用ISO/TC60/WG6标准中的BLOK闪温原理,通过对齿轮抗胶合承载能力的优化设计,获得了确定最佳移距系数的等抗胶合均衡温度T f1=T f2曲线(各种齿数共计215幅),做为选择抗胶合设计最佳移距系数的依据,从而使预期设计成为可能并更加合理。本文还进一步创造了一个闪温T f的简便算法,即T f=A·g m·C,式中,A= 4.6,g m——等抗胶合几何系数,其值由新封闭图中给出,C——齿轮工况影响系数,其值由文中公式给出,从而使BLOK闪温的计算大大简化,而且可得到和计算机同样精确的结果。文中最后还运用灾例介绍了如何用均温曲线封闭图选择移距系数及如何用简化公式计算闪温的方法。

Abstract: This Paper introduces the BLOK flash temperature and the optimum design of the anti scoring loadcarrying capacity of gears, and thus obtains the equal anti-scoring equilibrium temperature Tf1=Tf2 curve(various gear teeth totalled 215), which can be used to choose anti scoring design optimum correction factors and therefore to make the desirable design not only possible but also much reasonable. In addition, this article has further developed a Simplfied method for calculating the flash tempe rature Tf as follows:T f=A·g m·C where A=4.6 Gm -the equal anti-scoring geometry factor, the value of which is given in the new closed chart C -the effect factor for gearworking, the value of which is obtained through the formula shown here in this article The method above has made the calculation of the BLOK flash temperature much simpler and can obtain as accurate results as a computer does. Some examples are given in the end of this paper, telling the way both, of choosing the correction factors by using the equilibium temperature curve closed chart and of calculating the flash temperature by using the simplified formula.
