8 – GearsIntroductionD ELRIN®acetal resins and Z YTEL®nylon resins are used in a wide variety of gear applications throughout the world. They offer the widest range of operating temperature and highest fatigue endurance of any thermoplastic gear mate-rial, accounting for their almost universal use in non-metallic gearing.The primary driving force in the use of plastic vs. metal gears is the large economic advantage afforded by the injection moulding process. In addition, cams, bearings, ratchets, springs, gear shafts and other gears can be designed as integral parts in a single moulding, thus elim-inating costly manufacturing and assembly operations. Tolerances for plastic gears are in some cases less critical than for metal gears because the inherent resiliency enables the teeth to conform to slight errors in pitch and profile. This same resilience offers the ability to dampen shock or impact loads. The use of Z YTEL®nylon resin as the tooth surface in engine timing chain sprockets is an outstanding example of this latter advantage. In this case, timing chain life is extended because nylon dampens somewhat the transmission of shock loads from fuel igni-tion. Z YTEL®nylon resin and D ELRIN®acetal resin have low coefficients of friction and good wear characteristics, offering the ability to operate with little or no lubrication. They can also operate in environments that would be adverse to metal gears. A summary of the advantages and limitations of plastic gears is given in Table 8.01. Knowledge of the material performance characteristics and use of the gear design information to follow is impor-tant to successful gear applications in D ELRIN®acetal resin and Z YTEL®nylon resin.Gear DesignThe key step in gear design is the determination of the allowable tooth bending stress. Prototyping of gears is expensive and time consuming, so an error in the initial choice of the tooth bending stress can be costly.For any given material, the allowable stress is dependent on a number of factors, including:–Total lifetime cycle.–Intermittent or continuous duty.–Environment – temperature, humidity, solvents, chemicals, etc.–Change in diameter and centre to centre distance with temperature and humidity.–Pitch line velocity.–Diametral pitch (size of teeth) and tooth form.–Accuracy of tooth form, helix angle, pitch diameter, etc.–Mating gear material including surface finish and hard-ness.–Type of lubrication (frictional heat).Selection of the proper stress level can best be made based on experience with successful gear applications of a simi-lar nature. Fig. 8.01 plots a number of successful gear applications of D ELRIN®acetal resin and Z YTEL®nylon resin in terms of peripheral speed and tooth bending stress. Note that all of these applications are in room temperature, indoor environments. For similar applications operating at higher temperatures, the allowable stress should be corrected, see factor C1in Table 8.02. Since fatigue endurance is reduced somewhat as temperature increases, this effect must also be considered. Where very high tem-peratures are encountered, thermal ageing may become a factor.Where suitable experience is not available, the allowable tooth stress must be based on careful consideration of all the factors previously outlined, and on available test data on the gear material of choice.Table 8.01Advantages and Limitations of Plastic GearsAdvantages LimitationsEconomy in injection moulding Load carrying capacityCombining of functions Environmental temperatureNo post-machining or burr removal Higher thermal expansion coefficientWeight reduction Less dimensional stabilityOperate with little or no lubrication Accuracy of manufactureShock and Vibration dampingLower noise levelCorrosion resistance5960A number of years ago, DuPont commissioned a series of extensive gear tests on gears of D ELRIN ®acetal resin and Z YTEL ®nylon resin, which resulted in the information summarised in Tables 8.02 and 8.03. This data can be combined with environmental operating conditions to arrive at an allowable tooth bending stress.Whether similar experience exists or not, it is essential that a prototype mould be built and the design carefully tested in the actual or simulated end-use conditions.®®Table 8.03Fatigue Strength (σ1) for DuPont gear materials for 106cycles (MPa)LubricationMaterial Mating Material Continuous InitialD ELRIN ®100Steel 4827D ELRIN ®500Steel 3618Z YTEL ®101Steel 4025Z YTEL ®101Z YTEL ®10118Once the admissible tooth bending stress has been deter-mined, the designer can proceed with the selection of theother variables, for which an understanding of the basic terminology used in gear work is helpfull. The terms most commonly used to describe gears are:–Pitch diameter (d) is the diameter measured at the pitch circle.–Diametral pitch (P d ) is the number of teeth per inch of pitch diameter, commonly used in USA.–Module (M) is pitch diameter divided by number of teeth (z). Thus: M = d/z.For standard gears:•external diameter = d + 2M;•tooth thickness = 0,5 πM;•tooth height = 2M + clearance.–Pinion is the smaller of a pair of meshing gears.–Gear is the larger of a pair of meshing gears.–Ratio is number of teeth gear/number of teeth pinion.Fig. 8.01Speed versus stress: Typical gear applications placed on curve61Gear with off-centre webin the rim or the web, then web thickness should equalhub thickness, as no section of a given thickness can befilled properly through a thinner one.The maximum wall thickness of the hub should usuallynot exceed 6 mm. For minimum out-of-roundness, useOn gears which are an integral part of a multifunctionalcomponent or which have to fulfill special requirementsas shown in Fig. 8.20-8.25, it could be impossible toapproach the ideal symmetrical shape as shown inFig. 8.03, in which case the assembly must be designedto accept somewhat less accuracy in the gear dimensions.The following additional examples illustrate a few moregear geometries which could lead to moulding and/orfunctional problems:Relatively wide gears which have the web on one sidewill be rather difficult to mould perfectly cylindrical,especially if the centre core is not properly temperaturecontrolled. If the end use temperature is elevated, thepitch diameter furthest from the web will tend to besmaller than the pitch diameter at the web (Fig. 8.04).Effect of radial ribs Ribbed worm take-off gear 6263Low shrinkageHigh shrinkageGate3 GatesWeld linesFig. 8.08Holes and ribs in moulded gearsFig. 8.09Centre gated gearFig. 8.10Web gated gear Measurement of tooth profile errorTotal profile errorBacklash and Centre DistancesAs shown in Fig. 8.11-e backlash is the tangential clear-ance between two meshing teeth. Fig. 8.12 providesa suggested range of backlash for a first approach.It is essential to measure and adjust the correct backlash at operating temperature and under real working condi-tions. Many gears, even though correctly designed and moulded fail as a result of incorrect backlash at operating conditions.64Center distance measuring instrumentFig. 8.11-c Center distance variation diagramFig. 8.11-d Moulding tolerances from center distance diagramTotal composite errorRunoutOne revolution of gearTooth-to-tooth errorT 1T65LubricationExperience has shown that initial lubrication is effective for a limited time. Units disassembled after completion of their service life showed that all the grease was thrown on the housing walls; hence the gears ran completely dry. Initial lubrication does not allow a high load, it should be considered as an additional safety factor. It should, however, always be provided as it helps greatly during the run-in period.On applications where lubricant cannot be tolerated, the combination of D ELRIN®acetal resin and Z YTEL®nylon resin offers great advantages. Even under dry conditions such gear trains run smoothly and with little noise. Where continuous lubrication of gears in D ELRIN®acetal resin and Z YTEL®nylon resin is practical, and where surface pressure on the meshing teeth is not excessive, wear is negligible and service life is determined exclu-sively by fatigue resistance.Testing Machined PrototypesThough it would appear that the easiest way to determine whether a proposed gear will show the expected perform-ance would be to test machined prototypes, results thus obtained must be interpreted with great care. A designer has no guarantee that a subsequently moulded gear will have the same performance characteristics. Therefore no final conclusion can be drawn from test results using machined gears. Making a trial mould is the only safe way to prototype a gear design. It allows not only mean-ingful tests but also the measurement of shrinkage, tooth profile, pitch diameter and overall accuracy.It is highly recommended to check tooth quality on a pro-file projector which enables detection of deviation from the theoretical curve.Prototype TestingThe importance of adequate testing of injection moulded prototype gears has been emphasized. Here are some guidelines:–Accelerated tests at speeds higher than requiredof a given application are of no value.–Increasing temperature above normal working tempera-ture may cause rapid failure whereas under normal working conditions the gear may perform well. Test conditions should always be chosen to come as close as possible to the real running conditions.The following examples further explain the need for meaningful end-use testing.–Gears under a high load (e.g., in appliances) which operate only intermittently should not be tested in a continuous run, but in cycles which allow the whole device to cool down to room temperature between running periods.–Infrequently operated, slow-running gears (such as window blinds) can be tested in a continuous run but at the same speed, providing temperature increase on the tooth surfaces remains negligible.–Other applications like windshield wiper gears reach their maximum working temperature quickly, and oper-ate most of their service life under these conditions. They should therefore be tested on a continuous-run base.Valuable conclusions can often be drawn from the static torque at which a moulded gear fails. If breaking torque proves to be 8-10 times the operating load, it can usually be taken as an indication that the gear will provide a long service life in use. However, plastic gears often operate very close to the endurance limit, and the above relation should not be considered as valid in all cases.In any event, backlash must be checked during all tests. Once a gear has failed, it is almost impossible to deter-mine whether incorrect backlash was partially or entirely responsible.Helical Gear DesignWhenever possible, helical gears should be used in pre-ference to spur gears. Among other advantages they run more smoothly and have less tendency to squeak. However, they require not only perfect tooth profiles but also exactly matching helix angles. This requirementis sometimes difficult to fulfill, especially if the plastic gear meshes with a metal gear.Helical gears generate axial thrust which must be con-sidered. It is advisable to use helix angles not greater than 15°. Compared to a spur gear having the same tooth size, a helical gear has slightly improved tooth strength. Since small helix angles are most commonly used, this fact can be neglected when determining the module and it should be considered as an additional safety factor only.66Fig. 8.13One piece worm gear9 side coresFig. 8.14Side-cored worm gearFig. 8.15Half throated worm gearFig. 8.16Split worm gear676869Worm gearof D ELRIN®dαWorm of Z YTEL® 101Fig. 8.18Can opener with worm drive70Fig. 8.21Impact resistant webFig. 8.20Ratchet and gear combinedFig. 8.22Backlash-free gear71Backlash-free gearFig. 8.24Torque limiting gearFig. 8.25Gear with sliding coupling 72When to use D ELRIN®Acetal Resin or Z YTEL®Nylon ResinZ YTEL®nylon resin and D ELRIN®acetal resin are excellent gear materials, used extensively in a variety of applica-tions. The choice of one over the other may at first seem unclear, but as one examines the specific requirements of the application, it becomes relatively easy. Although the two materials are similar in many ways, they have distinct property differences, and it is these differences upon which the selection is made. Some guidelines are as follows:Z YTEL®Nylon Resin–Highest end-use temperature–Max. impact and shock absorption–Insert moulding–Max. abrasion resistance–Better resistance to weak acids and bases–Quieter runningD ELRIN®Acetal Resin–Best dimensional stability–Integrally moulded springs–Running against soft metals–Low moisture absorption–Best resistance to solvents–Good stain resistance–Stiffer and stronger in higher humidity environmentAs previously pointed out, running D ELRIN®acetal resin and Z YTEL®nylon resin against each other results in lower wear and friction than either material running against steel (not always true when high loads are encountered and heat dissipation is controlling). Some designers have used this combination in developing new, more efficient gear systems.When properties of D ELRIN®acetal resin are needed,D ELRIN®100 is the preferred gear material. As previously stated, D ELRIN®100 outperforms D ELRIN®500 by about 40%. D ELRIN®100 is the most viscous in the melt state, and cannot always be used in hard to fill moulds. D ELRIN®500 and 900 have been used successfully in many such cases.When Z YTEL®nylon resin is the chosen material,Z YTEL®101L is the most common material used.Z YTEL®103HSL, a heat stabilized version ofZ YTEL®101L, should be specified if the service life and end use temperature are high.Glass reinforced versions of either material should be avoided.The glass fibres are very abrasive and the wear rate of both the plastic gear and the mating gear will be high. Gears which operate for extremely short periods of time on an intermittent basis have been used with glass reinforcement to improve stiffness, strength or dimen-sional stability.Very careful testing is mandatory.The moulding conditions must be controlled carefully, not only for the usual purpose of maintaining gear accuracy, but also because glass reinforced resins will exhibit large differences in surface appearance with changes in mould-ing conditions, particularly mould temperature. It is pos-sible to vary mould temperature without changing dimen-sions, by compensating through adjustments in other process variables. Thus, establish surface smoothness specifications to be sure the type of gear surface tested is reproduced in mass production.73。

杜邦安全理念课件

伊雷内·杜邦曾师从于“现代化学之父”、著名化学家、法国皇家火药厂总监拉瓦锡。到达美国之后,发现美国火药质次价昂,而他掌握着能够比之更好的火药生产技术,因此,他决定开办火药厂。他与合伙人皮埃尔·鲍迪一起,买进了位于布兰迪万河畔的一座名叫布鲁姆的农场,于1802年4月建立了当时美国最大的火药厂,杜邦公司从此诞生了。
1834年,杜邦公司的第一代管理者伊雷内·杜邦去世后,其子亨利·杜邦这位被称为“将军”的铁腕人物是杜邦公司的第二代管理者,主管杜邦公司近40年。1889年,美国92.5%的火药生产已垄断在杜邦公司手中。这一时期主管杜邦公司的是第三代管理者尤金·杜邦,是亨利·杜邦的侄子。依托发达的信用制度和法律的保护,1899年底一个新的大型股份有限公司“E·I·杜邦·德·尼莫尔股份有限公司”成立,宣告杜邦公司实现了第一次转变:由家长式管理向现代企业管理的转变。
对此,杜邦中国总经理方梅珠解释说:“杜邦的原则就是,如果你不能保证遵守这样的‘天条’,我们宁可不要你在这里工作。我们不希望看到员工受到伤害。对于那些可能造成严重伤害的违规行为,不是我们不给员工机会,而是机会不给我们;而对于那些不会造成严重伤害的违规行为,我们会给员工时间来调整自己的状态的。”
法国大革命前,伊雷内·杜邦的父亲曾与时任美国驻法国公使的托马斯·杰斐逊成为亲密的朋友。不久以后,托马斯·杰斐逊当选为美国总统,这使杜邦家族在美国的开发计划如鱼得水,赢得了大批政府合同。1805年,美国陆军部长宣布,杜邦公司将承包政府的全部火药生产。鉴于火药制造行业的危险性,伊雷内·杜邦为在工厂事故中死亡的家庭建立了抚恤制度,使每个因公死亡的工人家庭每月能得到10美元的抚恤金。

目前,R-134a制冷剂被汽车行业广泛使用。
但是,R-134a对环境仍然有损害。
2006年2月1日,欧盟针对汽车行业颁布规定,2011年以后所有投放市场的新车型用的制冷剂GWP (全球温室效应潜值)必须小于150,2014年以后所有新车的制冷剂GWP必须小于150。
作为R-134a的替代品,CO2的GWP等于1,但工作压力4倍于R-134a,因此车辆的制冷系统设计改造投资大,设备改造后通用性差,配件采购困难
杜邦正在研发R-134a的替代品,即符合欧盟要求的HFC-1234yf。
它的GWP等于4,具有与R-134a相似的低毒性和相似的系统性能,优良的制冷能力且没有温度滑移。
它的热稳定性与R-134a的组件相兼容,可控制的中度可燃性,比任何其他替代品更少的转换成本。
HFC-1234yf有望直接替代R-134a而成为新的车用制冷机,并直接用于膨胀形空调系统。
