        摘要：In this paper, the varying rules of the linear load distribution and the largest stress along the contacting lines are analyzed based on the EHL theory. Applying the method of Newton-Raphson and Newton dowm-hill together, under the assumption of the equal rigid central film thickness, the numerical resolutions along all contacting lines at a time are gained about the helical gears before modification. Based on this, the load and pressure distribution and film thickness of each point along all the contacting lines at a time about the modified belical gears are calculated.On the basis of the laser transmission thohnology used in the reference[4], a sst of data collecting and processing system with a computer was researched. The central film thickness of the helical gears were measured. The measuring results are basically identical to the calculating ones. These show the reasonability and the reliability of the numerical analyzing model established.

From the analyses on breaking sections, metallographic examination and the measurement on hardness. hardendepth & impact toughness, the results shows that the imperfection of mechanical process, the low temperature embrittlement of 20Cr2Ni4A steel which is used widely for heavy duty gears is the most important factor affecting the qualitites of gears during the heat treatment. By the deliberate investigation on low temperature embrittlement of 20Cr2Ni4A, it presents the reasonable low temper temperature range for manufacture.

      • Statistical Analyses or Characteristics for Gear System at Overseas

        Issue 4, (1995) DOI: 10.16578/j.issn.1004.2539.1995.04.013
        摘要：Dynamic analysis in gearing system is usually treated as a deterministic problem. However in engineering practice many factors make either the inner excitation or the outer excitation in gearing system undeterministic. Therefore the dynamic behavior is frequently random. It is necessary to analyze the gear dynamic behavior by statistical method. The development on statistical analysis of gear dynamic behavior in the past 25 years is introduced in this paper.

      • 变位斜齿轮法向公法线的跨齿数公式评析

        Issue 4, (1995) DOI: 10.16578/j.issn.1004.2539.1995.04.014
        摘要：斜齿轮公法线跨齿数的计算只有由端面齿廓导出的公式是准确的；由法向齿形导出的或直齿轮的公式，代入齿形与该法向齿形最相似的当量齿轮的齿数，也可以得到相当准确的计算值；若以与斜齿轮仅存在公法线等长关系的假想齿数代入，准确性就会因螺旋角的增大而显著降低。变位系数和较大的齿轮副即使用准确的推导公式计算，所得测量点也常太偏近齿顶圆，因为推导公式的理想测量圆并不理想；推荐一组于各种情况下皆适用的跨齿数计算公式。
