一界限滑润当轴在轴承中转动时,若滑润情况完善,轴的外表披着一层厚的油膜,轴与轴承间的摩擦面便不直接接触,所以也不会有摩损,轴好像是浮在油膜中转动一样,此时所产生的摩擦阻力,只随油的黏度而变,而与轴承材料的物理性能无关。这一种滑润情况,称之谓完全滑润。若将油加压注入转速快而荷重小的轴上,轴面似乎可以黏着一层油膜,但轴与轴承仍有摩损,足见摩擦面上金属的直接接触,是无法避免的。所谓完全
A limit of lubrication When the axis of rotation in the bearing, if the lubrication conditions improve, the shaft is covered with a thick film of oil, the friction surface between the shaft and the bearing will not be in direct contact, so there will be no wear and tear, the shaft seems to be Floating in the oil film in the same rotation, the frictional resistance generated at this time, only with the viscosity of oil and change, and the physical properties of the bearing material has nothing to do. This kind of slippery situation, saying that completely smooth. If the oil injected into the fast speed and load on a small shaft, the shaft surface seems to be able to adhere to a layer of oil film, but the shaft and the bearing is still wear and tear, showing that the friction surface of the metal in direct contact is inevitable. The so-called complete
