润滑是金属机械加工中不可忽视的关键环节,它对设备的保护、生产效率的提高起着积极的作用。特别是在产品竞争矛盾显得更加突出的今天,润滑对提高产品质量尤其显得重要。因此迫使我们对润滑这一课题不得不作一番深入细致的探讨。就润滑来讲,可分为动压润滑和静压润滑两种,现就动压润滑加以讨论。众所周知,润滑剂的作用是在摩擦副表面产生一油膜,以避免摩擦副之间的直接接 Lubrication is a key link that can not be ignored in metal machining. It plays a positive role in the protection of equipment and the improvement of production efficiency. Especially in the conflict of product competition is more prominent today, lubrication is particularly important to improve product quality. So forcing us to lubricate the subject have to make some in-depth and meticulous discussion. In terms of lubrication, can be divided into two kinds of dynamic pressure lubrication and hydrostatic lubrication, dynamic pressure lubrication are discussed. As we all know, the role of lubricant in the friction surface to produce an oil film, in order to avoid friction between the direct
