聚合物齿轮具有自润滑性好、生产成本低等优点。受载荷、润滑等影响,聚合物齿轮在传动中易发生点蚀失效。与聚合物-聚合物齿轮副相比,金属-聚合物齿轮副有较长使用寿命。为了探究在润滑条件下金属-聚合物齿轮副弹流润滑性能,在不同工况条件下对钢-聚合物齿轮副进行了弹流润滑分析,通过膜厚比和油膜安全系数判断齿轮副润滑状态以及是否存在微点蚀失效。结果表明,钢-聚甲醛(POM)齿轮副在油润滑下能够形成稳定润滑油膜;压力角、转速、载荷和黏度都会影响齿轮的润滑状态。因此,为避免发生点蚀失效,需要考虑压力角、转速、载荷和润滑油黏度的影响。
Polymer gears have the advantages of good self-lubrication and low production cost. Polymer gears are susceptible to pitting failure in transmission due to load
lubrication
etc. Metal-polymer gears' pairs have a longer service life than polymer-polymer gear pairs. To investigate the performance of elastohydrodynamic lubrication for metal-polymer gear pairs under lubrication condition
analysis of elastohydrodynamic lubrication is carried out for steel-polymer gear pairs under different working conditions
and the lubrication status and micro-pitting failure are determined by film thickness ratios and oil film safety factors. The results show that steel-polyoxymethylene (POM) gears' pairs can form stable lubricant film under oil lubrication
and the pressure angle
the rotational speed
the load and the viscosity can affect the lubrication state of gears. Therefore
the effects of pressure angle
rotational speed
load and lubricant viscosity need to be considered to avoid pitting failure.
