本文论述龆轮、齿轮或整个啮合轮系齿面疲劳寿命的数学模型。其理论是以(Lundberg)和(palmgern)在滚动轴承计算中用过的统计方法为基础。本文还给出了齿轮装置承载能力的公式。这里指的承载能力是圆周力,在该圆周力下能使龆轮回转一百万转的齿轮装置,具有生存概率90％。把分析结果与用AISI9310钢做的直齿轮在最大赫兹应力1.71×10~9N/m~2(248,000psi),转速为10,000rpm进行试验的数据进行比较。如把从滚动轴承试验中得到的材料常数用于齿轮寿命模型时,预期的理论寿命是相当准确的。
This article discusses the mathematical model of the fatigue life of the pinion, pinion, or meshing gear system. The theory is based on the statistical methods used by Lundberg and Palmgern in rolling bearing calculations. The paper also gives the formula of bearing capacity of gear device. Here refers to the carrying capacity is a circular force, under the circular force can make the pinion rotation of one million rev gear device, with a survival probability of 90%. The results of the analysis were compared with those of spur gears made of AISI 9310 steel at a maximum Hertz stress of 1.71 × 10 -9 N / m 2 (248,000 psi) and a speed of 10,000 rpm. The expected theoretical life expectancy is quite accurate when using the material constants obtained from rolling bearing tests for the gear life model.
