The oiling is done with higher wages, well-ventilated factories and piped music, and by psychologists and "human-relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he does not wholeheartedly participate in his work and that he is bored with it.

小齿轮的润滑是通过高薪、通风良好的厂房、管乐及心理学家和人际关系专家来进行的。然而，这种润滑并未改变这样一个事实：人已变得无能为力，不再全心全意投入到工作，并对工作感到厌烦。

Based on the EHL theory, the average flow model and the asperity contact theory, the study is presented for mixed lubrication of piston pin bearing.

Diamond's Ring Leader O-ring chain is specifically designed for applications that don't permit regular lubrication, requiring the chain to depend entirely upon initial factory lubrication throughout its service life.

Diamond 的的 O 型环链是专为应用程序，不允许定期润滑，要求链从初始工厂起，完全润滑在其整个使用寿命中。

In this paper, firstly, the lubrication and wear-resisting mechanism of the surface with regular micro-structure is studied and the corresponding lubricated theory model is also developed. And then, use modified multi-grid method to solve the theory model, and cylinder wall surface micro geometry shape parameters are designed and optimized.

本文首先通过研究具有规则微观几何形貌表面的润滑、减磨机理，建立相应的缸套—活塞环摩擦副润滑理论数学模型，利用变异的多重网格法求解此数学模型，对缸套表面微观几何形貌设计参数进行优化匹配。

All of these are a reliable basis for the planetary gear transmission in scraper conveyer in wear-resistance design.

探讨了刮板输送机中行星齿轮传动的弹性流体动力润滑计算，并推导出相应的计算公式；分析了传动润滑状态与磨损的关系，为刮板输送机中行星齿轮传动的耐磨损设计提供了必要的理论依据。

The basic desing of self-aligning ball bearing has a cylindrical hole or a taper hole at some size.

这些轴承的外圈和内圈有一个环形槽和几个润滑孔，内圈则有润滑孔。

Moving my cock to the position I was about to say 'It might hurt..' but feeling the slickness of her pussy against my cock I thought again.. Pushed forward.. And eased in, smooth, gliding.. and though she gasped as I filled her, it was from pleasure not pain; and this is the first time it has happened so easily.

当我把我的生殖器移到这位置时，我想说"它可能会弄疼你…"但是感觉到她的生殖器的润滑度我又想了一下…推向前，然后顺利地进入了，很润滑，很流畅…当我填充她时她呻吟了，但这是因为开心而不是疼痛；而这是第一次那么容易。

The power and utilizes the combination of splash lubrication and forced lubrication.

e。 采用强制润滑和飞溅润滑相结合的方式。
