八十、润滑的作用是什么?任何两个机械零件接触的表面在相对运动时,都存在着摩擦现象。摩擦会使零件磨损,多消耗动力,又使接触面发热、甚至破坏。因此,如何减少摩擦是机械设计、制造和使用时的重要问题。润滑就是减少机械设备摩擦极为重要的手段。为了保征设备能延长使用寿命,保持机械精度,充分发挥机械效率和减少能源消耗,必须十分重视机械设备的润滑。所谓润滑,就是将润滑材料加入作相对运动的接触表面,来达到减少摩 Eighty, what is the role of lubrication? The contact surface of any two mechanical parts in the relative movement, there is a friction phenomenon. Friction will wear parts, more power consumption, but also make the contact surface fever, or even damage. Therefore, how to reduce friction is an important issue in mechanical design, manufacture and use. Lubrication is a very important tool to reduce the friction of machinery and equipment. In order to levy equipment to extend the service life, maintain mechanical precision, give full play to mechanical efficiency and reduce energy consumption, we must attach great importance to the lubrication of machinery and equipment. The so-called lubrication, is to join the lubricating material for the relative movement of the contact surface, to reduce friction
