Abstract The tribological and vibrational behaviors of conventional and textured spur gear pairs were experimentally explored under fully flooded and starved lubrication conditions at different operating parameters. Three different gear tooth profile textures were created by creating vertically oriented ellipsoid, horizontally oriented ellipsoid, and hemispherical dimples in zigzag patterns using a nanosecond pulsed fiber laser. Tribological parameters (contact resistance, temperature rise, and surface topography) and vibration (in time and frequency domains) were obtained, compared, and analyzed. The results revealed a reduction in vibration amplitudes, increase in contact resistance, decrease in temperature rise, and less damage of mating surfaces in the presence of textures. Moreover, the texture with vertically oriented ellipsoidal dimples yielded the best results.

满油润滑和缺油润滑条件下带纹理的正齿轮副的摩擦学和振动研究

摘要 在不同操作参数下，在完全充满和缺乏润滑条件下，通过实验研究了传统和纹理直齿轮副的摩擦学和振动行为。通过使用纳秒脉冲光纤激光器以锯齿形图案创建垂直方向的椭球、水平方向的椭球和半球形凹坑，创建了三种不同的齿轮齿廓纹理。获得、比较和分析摩擦学参数（接触电阻、温升和表面形貌）和振动（时域和频域）。结果表明，在存在纹理的情况下，振动幅度降低，接触电阻增加，温升降低，配合表面损坏更小。而且，
