1、Energol GR-XP A new standard in gear lubrication 齿轮润滑的新标准齿轮润滑的新标准Gear lubrication齿轮润滑 The main function of a gear oil is to separate the tooth surfaces and remove frictional heat 齿轮油的主要功能是分隔齿轮接触表面，并散热 Splash lubrication is usually sufficient for low speed gears-pitch line velocity below 15 m/s 飞溅润滑通

2、常有效地用于节线速度低于15m/s的低速齿轮副 Jet spray lubrication for higher speeds 喷射润滑用于高速齿轮副Gear failures齿轮的失效 Definition-a gear pair HSA not failed until it can no longer be run 定义齿轮副不能再运转 Usually one or more teeth break preventing transmission of motion or teeth become so badly damaged that vibration and noise are

3、 unacceptable 通常是一个或多个齿发生断裂，使齿轮不能传送动力；或者是齿轮损坏严重产生巨大的震动和噪音 Gear failures are rare 齿轮的失效通常较少Types of gear tooth damage齿轮损坏的类型 Micro-pitting 微点蚀 Pitting 点蚀 Scuffing 咬接 Slow speed wear 低速磨损 Corrosion 腐蚀 Plastic deformation 塑性变形 Breakage 断裂FZG gear test rigFZG 齿轮试验装置Widely used for practical testing of g

5、 A fatigue phenomenon that involves contact stress,material properties,heat treatment and a lubricant 这是涉及到接触应力、材料特性、热处理和润滑油的疲劳现象Scuffing咬接 Result of disruption of the lubricant film 润滑油膜破裂的结果 Metal to metal contact roughens and tears the tooth surfaces 金属间的直接接触使齿轮表面变粗糙，造成撕裂 Apart from loading and s

6、liding velocity,the lubricant is the major factor influencing scuffing 除去负载和滑动速度的影响，润滑油是主要的因素Micro-pitting微点蚀 Also known as grey flecking,grey staining,grey frosting and grey spotting又被称为灰斑、灰污、灰霜或灰点 Appears as grey lines or spots on the flanks of hardened gear teeth在硬化齿面的中部形成的灰线或坑 Consists of numero

7、us,very small micro-pits 10-20 microns wide and similar depth 包含有大量的、非常小的、宽度和深度约10-20微米的微点蚀 Does not always lead to gear failure and can be controlled with suitable lubricants通常不会导致齿轮的失效，并可通过使用适当的润滑油加以控制Micro-pitting cont.微点蚀（续）Micro-pitting is increasingly regarded as a precursor to other modes of

8、failure such as macro-pitting,scuffing,tooth fracture as well as increased noise and vibration越来越多的人认为微点蚀是其它失效形式的先兆，如：点蚀、咬接、齿轮断裂、不断增大的噪音和震动 Some manufacturers have now introduced specific tests for assessing the micro-pitting resistance of lubricants into their approval procedure现在许多制造商为了评价润滑油抗微点蚀的能

9、力，已在他们的认可程序中加入了特定的试验Industrial gear lubricants工业齿轮油 Usually comprise of base oil plus additives通常包含了基础油和添加剂 Base oils can be mineral oil or synthetic fluids or mixtures of both基础油可以是矿物油、合成油或二者的混合物 Lubricant characteristics are determined by the formulation of the base oil and the additives润滑油的特性由基础油
