Abstract To increase the efficiency of a gearbox, research on gear mesh loss is of importance. Britton et al. concluded that the surface finishing method affects the gear mesh efficiency. The efficiency benefits of superfinishing a surface and reducing the surface roughness have been reported by Kahraman. A novel method for calculating the bearing loss torque was proposed by Tu et al. Andersson et al. found that the efficiency can vary between 2 and 5% during repeated efficiency tests due to variations in the assembly process. This work investigates how the honing surface finishing process and DIN 3962 quality class affect the gear mesh efficiency by performing tests in an FZG back-to-back test rig. Two materials, a powder metal and a wrought steel, were tested. All gears were finished using a honing process and sorted according the measured quality class. Powder metal gears of class 6, 7, 8, and ≥9 and wrought steel gears of class 6, 7, and ≥9 were tested. The efficiency were calculated from measuring the torque required to maintain a constant velocity of the FZG test rig. The results from the efficiency tests showed no significant difference in efficiency between the wrought steel and powder metal steel gears. In addition, no obvious correlation between the DIN 3962 quality class and the gear mesh efficiency could be found. When examining the wrought steel material it was found that the reproducibility of the efficiency was comparable to the assembly error of the test rig, despite the variation in quality class.

DIN 3962 质量等级对珩磨粉末金属和锻钢齿轮效率的影响

摘要 为了提高齿轮箱的效率，齿轮啮合损失的研究具有重要意义。布里顿等人。得出的结论是，表面精加工方法会影响齿轮啮合效率。Kahraman 报告了超精加工表面和降低表面粗糙度的效率优势。Tu 等人提出了一种计算轴承损失扭矩的新方法。安德森等人。发现在重复效率测试期间，由于组装过程的变化，效率可能在 2% 到 5% 之间变化。这项工作通过在 FZG 背靠背试验台上进行试验，研究珩磨表面精加工工艺和 DIN 3962 质量等级如何影响齿轮啮合效率。测试了两种材料，粉末金属和锻钢。所有齿轮均采用珩磨工艺精加工，并根据测量的质量等级进行分类。测试了 6、7、8 和 9 级的粉末金属齿轮和 6、7 和 9 级的锻钢齿轮。通过测量保持 FZG 试验台恒定速度所需的扭矩来计算效率。效率测试的结果表明锻钢和粉末金属钢齿轮之间的效率没有显着差异。此外，在 DIN 3962 质量等级和齿轮啮合效率之间没有发现明显的相关性。在检查锻钢材料时发现，尽管质量等级存在差异，但效率的再现性与试验台的装配误差相当。并且≥9 被测试。通过测量保持 FZG 试验台恒定速度所需的扭矩来计算效率。效率测试的结果表明锻钢和粉末金属钢齿轮之间的效率没有显着差异。此外，在 DIN 3962 质量等级和齿轮啮合效率之间没有发现明显的相关性。在检查锻钢材料时发现，尽管质量等级存在差异，但效率的再现性与试验台的装配误差相当。≥9 项进行测试。通过测量保持 FZG 试验台恒定速度所需的扭矩来计算效率。效率测试的结果表明锻钢和粉末金属钢齿轮之间的效率没有显着差异。此外，在 DIN 3962 质量等级和齿轮啮合效率之间没有发现明显的相关性。在检查锻钢材料时发现，尽管质量等级存在差异，但效率的再现性与试验台的装配误差相当。效率测试的结果表明锻钢和粉末金属钢齿轮之间的效率没有显着差异。此外，在 DIN 3962 质量等级和齿轮啮合效率之间没有发现明显的相关性。在检查锻钢材料时发现，尽管质量等级存在差异，但效率的再现性与试验台的装配误差相当。效率测试的结果表明锻钢和粉末金属钢齿轮之间的效率没有显着差异。此外，在 DIN 3962 质量等级和齿轮啮合效率之间没有发现明显的相关性。在检查锻钢材料时发现，尽管质量等级存在差异，但效率的再现性与试验台的装配误差相当。
