【摘要】 本文在引述有关文献基础上进一步分析产生最恶速度现象的原因，且认为最恶速度是磨损率变化的又一临界点，是边界润滑齿轮的摩擦学设计数据。更多还原

【Abstract】 In this paper,the cause of the worst velocity was furthurly analyzed.It was found that the worst velocity is another critical point of the wear rate and it can be used as a tribological criterion in designing gears operated in boundary lubrication condition.更多还原
