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外表,并散热,Splash lubrication is usually sufficient for low speed gears-pitch line velocity below 15 m/s,飞溅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 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 unacceptable,通常是一个或多个齿发生断裂,使齿轮不能传送动力;或者是齿轮损坏严峻产生巨大的震惊和噪音,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 gear lubricants,广泛用于齿轮油的应用试验,Load carrying capacity(scuffing test),承载性能咬接试验,Pitting,点蚀,Micro-pitting,微点蚀,Slow speed wear,低速磨损,Efficiency/energy saving,效率/节能性,Pitting,点蚀,The most common type of gear failure,齿轮失效最常见的形式,Small particles break away leaving small cavities or pits on the tooth surface,小颗粒崩裂在外表留下小坑或点蚀,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乏现象,Scuffing,咬接,Result of disruption of the lubricant film,润滑油膜裂开的结果,Metal to metal contact roughens and tears the tooth surfaces,金属间的直接接触使齿轮外表变粗糙,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,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 numerous,very small micro-pits 10-20 microns wide and similar depth,包含有大量的、特殊小的、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把握,Micro-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式的先兆,如:点蚀、咬接、齿轮断裂、不断增大的噪音和震惊,Some manufacturers have now introduced specific tests for assessing the micro-pitting resistance of lubricants into their approval procedure,现在很多制造商为了评价润滑油抗微点蚀的力气,已在他们的认可程序中参与了特定的试验,Industrial gear lubricants,工业齿轮油,Usually comprise of base oil plus additives,通常包含了根底油和添加剂,Base oils can be mineral oil or synthetic fluids or mixtures of both,根底油可以是矿物油、合成油或二者的混合物,Lubricant characteristics are determined by the formulation of the base oil and the additives,润滑油的特性由根底油和添加剂的配方预备,Vital characteristics,最重要的性能,Satisfactory viscosity at operating temperature and start-up,在操作温度和起动温度下适宜的粘度,Adequate wear protection,足够的抗磨损力气,Oxidative and thermal stability,氧化和热稳定性,Non-corrosive and rust protection,抗腐蚀性和防锈性,Resistant to foaming and forming emulsions,抗泡性和抗乳化性,Seal and paint compatibility,密封件和油漆的相容性,Industrial specifications,工业规格,AGMA,250.04,US S,teel No.224,DIN,51517 part 3,D,avid,B,rown,F,lender,F,lender,Globally the largest OEM of industrial gear transmissions,全球最大的工业齿轮传动装置的制造商,Flender was the first OEM to introduce micro-pitting resistance requirement for approving gear lubricants,Flender是第一个在润滑油认可中引入抗微点蚀要求的制造商,They are convinced that lubricants meeting this requirement are necessary to maintain the reliability and service life of their gear units.,他们认为为了保证齿轮装置的牢靠性和使用寿命,齿轮油必需满足这些要求,Oil requirements for use in,F,lender gear unitsFlender,齿轮装置的用油要求,DIN 51517 part 3,Flender foam test,Flender抗泡试验,Compatibility with materials of
