1-3-2-齿轮润滑的新标准解析课件

1、Energol GR-XP A new standard in gear lubrication 齿轮润滑的新标准Energol GR-XPGear 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

2、润滑通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 lubrication齿轮润滑The main 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

3、 that vibration and noise are 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Gear failures齿轮的失效Definition 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Types of gear too

6、 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 sliding 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Scuffing咬接Result of disruptioMicro-pitting微点蚀Also known as grey flecking, grey

7、 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 numerous, 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 co

8、ntrolled 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微点蚀Also known asMicro-pitting cont.微点蚀（续）Micro-pitting is increasingly regarded as a precursor to other modes of 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

9、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力，已在他们的认可程序中加入了特定的试验Micro-pitting cont.微点蚀（续）MicIndustrial gear lubricants工业齿轮油Usually comprise of base oil plus

10、 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和添加剂的配方决定Industrial gear lubricants工业齿Vital characteristics最重要的性能Satisfactory viscosity
