一、润滑管理LUBRICATION MANAGEMENT
“五定”润滑管理“5f”Lubrication management
1、定点：制定润滑点。 Fix point: Fix the lubrication points. 2、定人：定专人分别对各润滑点进行巡检维护。 Fix : Fix special staff for patrol of the lubrication points 3、定质：对润滑油品的油质进行监控。 Fix quality: Monitor the quality of the lubricant. 4、定量：制定各润滑点的加油量和补油量。 Fix quantity: Fix the changing quantity and filling quantity for each lubrication point. 5、定时：制定各润滑点的补油周期和换油周期，并严格执行。 Fix time: Fix the changing period and filling period for each lubrication point and carry
EP （EXTREME PRESSURE）的含义： Meaning of EP (EXTREME PRESSURE) 抗极压添加在高温下起反应，防止齿面粘接 The EP reacts at high temperature to prevent slice or joint form the gear surfaces 齿面在极压添加剂的作用下可以相对滑动 The gear surfaces can relatively slip with the EP 抗极压添加剂只有在需要时才发挥作用 EP only take action when needed. 齿轮润滑油的特性： Characteristics of gear lubricant: 正确的粘度、合适的低温流动性、良好的化学稳定性、良好的抗乳化性能、高 油膜强度、良好的润滑性、防锈性能、无腐蚀、抗泡性、极压性能 Correct viscosity, appropriate low temperature flow ability, excellent chemical stability, excellent emulsification resistance, high strength of oil slick, excellent lubrication, no corrosion, bubble resistance, extreme pressure performance
以齿轮油为例Take the gear oil for example： 影响润滑的因素The factors influence lubrication： 齿轮类型、齿轮速度（低速-高粘度，高速-低粘度）、减速比、运行温度 （环境温度、摩擦温度）、输入动力、载荷特性、驱动类型、润滑方式 （飞溅润滑、压力润滑）、水污染、润滑油的泄漏 Gear type, gear speed (low speed – high viscosity, high speed – low viscosity), reduction ratio, temperature (environment temp., friction temp.), driving force, loading type, driving method, lubrication method (splash lubrication, pressure lubrication), water pollution, lubricant leakage

二、润滑油基本知识介绍
Fundamental knowledge of lubrication
1、几个相关的概念Related concepts 摩擦 Friction 两个物体表面相互接触，并做相对运动受阻的现象。 The force that makes it difficult for things to move freely when they are touching each other. 磨损Wear 因摩擦使机械摩擦副接触面产生微粒脱落、变形、重量减轻 等表层损坏现象。 Wear is the damage or change that is caused by friction, such as the phenomenon of granule drop, deformation and less weight happened in the contact surface.

（2）、开式齿轮润滑剂油膜的特点 Characteristics of oil slick of the lubricant for exposed gear 由于开式齿轮的转速通常较小以及齿轮的啮合特点，大小齿轮 齿面间无法保持流体动力润滑状态 The rotating speed of the exposed gear is usually low, and it’s impossible for the hydrodynamic lubrication between the gears’ surfaces for the mesh characteristics of the gears. 需要加入固体添加剂防止摩擦区域发生金属和金属的直接接触 The solid additive is needed to prevent the direct contact between the metal surfaces
