摘要
在工業(yè)化發(fā)展的今天,各種機(jī)械產(chǎn)品層出不窮,精度要求不斷提高。齒輪傳動(dòng)作為傳動(dòng)機(jī)構(gòu)的重要組成部分,其精度高低直接影響產(chǎn)品質(zhì)量。因此,提高齒輪傳動(dòng)精度成為了提高產(chǎn)品質(zhì)量的一種方法。齒輪傳動(dòng)精度的高低主要受裝配精度、齒輪制造精度兩方面的影響
齒輪制造精度是由加工刀具來(lái)保證。而齒輪是加工齒輪的重要刀具,尤其是齒輪在加工各種齒輪的過(guò)程中得到了廣泛的應(yīng)用。所以,對(duì)齒輪精度的分析檢測(cè)是非常有必要的。

第1章 緒論
隨著國(guó)內(nèi)工業(yè)化的飛速發(fā)展,如汽車制造業(yè),航空航天工業(yè)、造船業(yè)、機(jī)械裝備制造業(yè)以及IT行業(yè)等的飛速發(fā)展,對(duì)各種工業(yè)產(chǎn)品的質(zhì)量提出了更高的要求,特別是各行業(yè)生產(chǎn)設(shè)備。而衡量這些生產(chǎn)設(shè)備的質(zhì)量的好壞最重要的一點(diǎn)就是其性能。性能的好壞主要又是由構(gòu)成設(shè)備的零部件精度決定的。所以,對(duì)零部件精度的掌握在一定程度上就體現(xiàn)出了公司對(duì)產(chǎn)品質(zhì)量把握,決定了公司的效益。
齒輪作為機(jī)械產(chǎn)品傳動(dòng)機(jī)構(gòu)的重要組成部分,對(duì)機(jī)械產(chǎn)品的性能有很重要的影響。所以,各大齒輪制造商在擴(kuò)大齒輪產(chǎn)量、增加齒輪品種的同時(shí),更加注重提高齒輪質(zhì)量。
影響齒輪質(zhì)量的因數(shù)很多,最直接的因數(shù)就是齒輪的加工刀具。齒輪是加工齒輪的重要刀具,尤其是齒輪在加工各種齒輪的過(guò)程中得到了廣泛的應(yīng)用。因此,研究齒輪測(cè)量技術(shù)和研制相應(yīng)的檢測(cè)儀器是非常必要的。
在早期的生產(chǎn)中,檢測(cè)齒輪加工刀具是否達(dá)到自己所希望的精度,通常用的是手動(dòng)測(cè)量裝置。不僅檢測(cè)精度很難保證,而且工作效率低,越來(lái)越難滿足人們生產(chǎn)需要。隨著機(jī)械工業(yè)和電子信息技術(shù)的發(fā)展與融合,我們把傳感器、脈沖電機(jī)等電子設(shè)備與機(jī)械機(jī)構(gòu)相結(jié)合得到了檢測(cè)更精確,工作效率更高的齒輪加工刀具誤差測(cè)量?jī)x。
本設(shè)計(jì)主要是對(duì)零齒輪的齒輪內(nèi)部缺陷進(jìn)行檢測(cè)。由于在設(shè)計(jì)中采用了先進(jìn)的機(jī)械電子技術(shù),提高了設(shè)備檢測(cè)精度與生產(chǎn)效率。所以,我們相信本設(shè)計(jì)的產(chǎn)品一定會(huì)比早期的產(chǎn)品更適合工業(yè)化生產(chǎn)。
1.1 課題分析
(1) 系統(tǒng)功能
實(shí)現(xiàn)一定尺寸范圍內(nèi)齒輪金屬零件自動(dòng)超聲檢測(cè)的功能,重點(diǎn)實(shí)現(xiàn)各種型號(hào)小汽車變速箱齒輪的內(nèi)部缺陷檢測(cè)。它可以發(fā)現(xiàn)齒輪中各種缺陷及缺陷的位置,按規(guī)范要求自動(dòng)判別是否報(bào)廢或返修,并予以顯示。除了裝、卸料和更換探頭外,全部操作過(guò)程在計(jì)算機(jī)的控制下自動(dòng)完成。
(2)被測(cè)工件:外徑>ф1000mm
(3)檢測(cè)要求的運(yùn)動(dòng)方式及運(yùn)動(dòng)參數(shù):
1)運(yùn)動(dòng)方式:工件旋轉(zhuǎn),探頭沿工件的徑向和軸向進(jìn)給掃描;
2)工件轉(zhuǎn)速范圍為:5~60r/min;
3)進(jìn)給速度:1~20mm/r(這里的每轉(zhuǎn)是指工件旋轉(zhuǎn)一周的進(jìn)給量)。
(4)探頭可以定量手工調(diào)節(jié)入射角度,調(diào)節(jié)范圍為±100。
第2章 總體方案設(shè)計(jì)
2.1 檢測(cè)裝置總體方案設(shè)計(jì)
系統(tǒng)總體方案設(shè)計(jì)內(nèi)容包括:
? 系統(tǒng)運(yùn)動(dòng)方式的確定。
? 伺服系統(tǒng)的選擇。
? 執(zhí)行機(jī)構(gòu)得結(jié)構(gòu)及傳動(dòng)方式的確定。
2.1.1系統(tǒng)運(yùn)動(dòng)方式的確定
數(shù)控系統(tǒng)按運(yùn)動(dòng)方式可分點(diǎn)位控制系統(tǒng)、點(diǎn)位直線系統(tǒng)、連續(xù)控制系統(tǒng)。點(diǎn)位控制系統(tǒng)是指被控制件由一點(diǎn)到另一點(diǎn)快速準(zhǔn)確定位,卻不能在兩點(diǎn)之間工作的系統(tǒng);點(diǎn)位直線系統(tǒng)是指被控制件沿平面內(nèi)平行于導(dǎo)軌作直線工作的系統(tǒng);連續(xù)控制系統(tǒng)是指被控制件沿平面內(nèi)任何曲線都能工作的系統(tǒng)。點(diǎn)位控制系統(tǒng)造價(jià)低廉,適用于兩點(diǎn)之間快速點(diǎn)位的系統(tǒng);連續(xù)控制系統(tǒng)造價(jià)高,適用于連續(xù)工作的系統(tǒng);點(diǎn)位直線系統(tǒng)造價(jià)介于前兩者之間,適用于簡(jiǎn)單直線運(yùn)動(dòng)。
由于齒輪齒形是直線,檢測(cè)齒輪內(nèi)部缺陷只需沿直線運(yùn)動(dòng),所以選擇點(diǎn)位直線控制系統(tǒng)。
2.1.2伺服系統(tǒng)的選擇
開環(huán)伺服系統(tǒng)在負(fù)荷不大時(shí)多采用功率步進(jìn)電機(jī)作為伺服電機(jī),開環(huán)控制系統(tǒng)由于沒(méi)有檢測(cè)反饋部件,因而不能糾正系統(tǒng)的傳動(dòng)誤差,但開環(huán)系統(tǒng)結(jié)構(gòu)簡(jiǎn)單、調(diào)整維修容易、在速度和精度要求不太高的場(chǎng)合得到廣泛應(yīng)用。
閉環(huán)伺服系統(tǒng)具有在設(shè)備移動(dòng)部件上得檢測(cè)反饋元件來(lái)檢測(cè)實(shí)際位移量,能補(bǔ)償系統(tǒng)的傳動(dòng)誤差。因而伺服控制精度高,閉環(huán)系統(tǒng)造價(jià)高、結(jié)構(gòu)和調(diào)試較復(fù)雜,多用于精度要求高的場(chǎng)合。
此儀器屬于測(cè)量?jī)x器,其分辨率為0.005mm,所測(cè)齒輪加工的齒輪精度:8級(jí),所以采用閉環(huán)伺服系統(tǒng)
2.1.3執(zhí)行機(jī)構(gòu)的確定
為保證數(shù)控系統(tǒng)得傳動(dòng)精度和工作平穩(wěn)性。在設(shè)計(jì)機(jī)械傳動(dòng)裝配時(shí),通常采用低摩擦、低慣量、高剛度、無(wú)間隙、高諧振以及有適宜的阻尼比要求的傳動(dòng)方式??紤]以上幾點(diǎn),本設(shè)計(jì)采用以下措施:
1、盡量采用低摩擦的傳動(dòng)和導(dǎo)向元件。如采用滾珠絲杠螺母副,滾動(dòng)導(dǎo)軌等。
致謝
本文主要闡述了齒輪檢測(cè)裝置設(shè)計(jì)。通過(guò)這次設(shè)計(jì)使我對(duì)齒輪加工過(guò)程產(chǎn)生了濃厚的興趣,同時(shí),受我主修專業(yè)的影響,我已經(jīng)習(xí)慣于設(shè)計(jì)帶來(lái)的一系列機(jī)遇與挑戰(zhàn)。
本篇論文雖然凝聚著自己的汗水,但卻不是個(gè)人智慧的產(chǎn)品,沒(méi)有導(dǎo)師的指引和贈(zèng)予,沒(méi)有父母和朋友的幫助和支持,我在大學(xué)的學(xué)術(shù)成長(zhǎng)肯定會(huì)大打折扣。當(dāng)我打完畢業(yè)論文的最后一個(gè)字符,涌上心頭的不是長(zhǎng)途跋涉后抵達(dá)終點(diǎn)的欣喜,而是源自心底的誠(chéng)摯謝意。我首先要感謝我的指導(dǎo)老師張文生老師,對(duì)我的構(gòu)思以及論文的內(nèi)容不厭其煩的進(jìn)行多次指導(dǎo)和悉心指點(diǎn),使我在完成論文的同時(shí)也深受啟發(fā)和教育。
再次由衷感謝答辯組的各位老師對(duì)學(xué)生的指導(dǎo)和教誨,我也在努力的積蓄著力量,盡自己的微薄之力回報(bào)母校的培育之情,爭(zhēng)取使自己的人生對(duì)社會(huì)產(chǎn)生些許積極的價(jià)值!

The appropriate gear and reasonable use of transmission gears can improve equipment performance but also could prolong gear life.Keywords Gear, characteristics, fault, applicationWheel gear's spreading to move is a the most wide kind of the application spreads to move a form in the modern machine.Its main advantage BE1 spreads to move to settle, work than in a moment steady, spread to move accurate credibility, can deliver space arbitrarily sport and the motive of the of two stalks;Power and speed scope2 applies are wide;3 spreads to move an efficiency high, η =0.92-0.98;4 work is dependable, service life long;5 Outline size outside the is small, structure tightly packed.The wheel gear constituted to°;;;from wheel gear, stalk, bearings and box body decelerates a machine, useding for prime mover and work machine or performance organization of, have already matched to turn soon and deliver a function of turning , the application is extremely extensive in the modern machine. 6 Local deceleration machine much with the wheel gear spread to move, the pole spread to move for lord, but widespread exist power and weight ratio small, or spread to move ratio big but the machine efficiency lead a low problem.There are also many weaknesses on material quality and craft level moreover, the especially large deceleration machine's problem is more outstanding, the service life isn't long.The deceleration machine of abroad, with Germany, Denmark and Japan be placed in to lead a position, occupying advantage in the material and the manufacturing craft specially, decelerating the machine work credibility like, service life long.But it spreads to move a form to still take settling stalk wheel gear to spread to move as lord, physical volume and weight problem, don't also resolve like The direction which decelerates a machine to is the facing big power and spread to move ratio, small physical volume, high machine efficiency and service life to grow greatly nowadays develops.Decelerating the connecting of machine and electric motor body structure is also the form which expands strongly, and have already produced various structure forms and various products of power model numbers.Be close to ten several in the last yearses, control a technical development because of the modern calculator technique and the number, make the machine process accuracy, process an efficiency to raise consumedly, pushed a machine to spread the diversification of movable property article thus, the mold piece of the whole machine kit turns, standardizing, and shape design the art turn, making product more fine, the beauty turns. Become a set a machine material In 21 centuries medium, the wheel gear is still a machine to spread a dynamic basic parts.CNC tool machine and the craft technical development, pushed a machine to spread to move structure to fly to develop soon.Be spreading to move the electronics control, liquid in the system design to press to spread to move, wheel gear, take the mixture of chain to spread to move, will become become soon a box to design in excellent turn to spread to move a combination of direction.The academics that is in spread move the design crosses, will become new spread a movable property article the important trend of the development. Is the use of gear teeth of two gears meshing each other transmission of mechanical power and motion transmission. According to the relative position of the gear axis parallel to axis of cylindrical sub-gear drive, bevel gear axis intersect and cross-axis helical drive gear. Compact structure, high efficiency, long life and so on. Gear refers to the main, driven wheel gear direct, movement and power transmission devices. Of all the mechanical transmission, the most widely used gear can be used to transfer between any two axes of motion and power.The characteristics of gear is: a smooth gear transmission, the transmission ratio accurate, reliable, high efficiency, long life, the use of power, speed and size range. For example, transmission of power from small to almost 100,000 kilowatts; speeds of up to 300m / s; gear diameter from a few millimeters to more than 20 meters. However, the need for specialized gear manufacturing equipment, the meshing noise transmission. Gear failure for the five forms, should be the appropriate design criteria established. However, tooth wear, plastic deformation and so on, as they have not been widely established and well-established engineering practice to use the calculation method and design data, so the gear drive design, it is usually only on the guarantee that the tooth root bending fatigue strength and tooth surface to ensure contact fatigue strength calculation of the two criteria. For high-power high-speed gear transmission (such as aero-engine main drive, drive turbine-generator unit, etc.), but also ensure the tooth surface by the anti-bonding capacity calculation guidelines. As for the ability to resist other failure, although generally not at present be calculated, but the measures to be taken to strengthen the tooth's ability to resist these failures. 1 closed gear transmission Informed by practice, in the closed gear transmission, usually to ensure that the main tooth contact fatigue strength. Tooth surface hardness for high strength and low core-tooth gear (such as 20,20 Cr steel by quenching after carburizing gears) or a more brittle material of the gear, usually at the tooth root bending fatigue strength to ensure that the main. If the two gears are hardened and the tooth surface hardness as high as, then as the case may be. Larger transmission power, such as the input power of 75kW closed more than gear, heat, easy to lead to bad lubrication and gear damage, such as glue, in order to control the temperature rise, but also for calculation of cooling capacity. 2 open-gear transmission Open (semi-open) gear drive, according to tooth surface is supposed to be based to ensure that anti-wear and anti-fracture ability Dedendum two criteria are calculated, but as mentioned earlier, on the tooth surface abrasion resistance of the method of calculating capacity is not perfect yet, so off-type (semi-open) gear drive, the current only to ensure that the tooth root bending fatigue strength as a design criteria. In order to extend the open (semi-open) the life of gear, the specific needs of visualization to be obtained by increasing the appropriate modulus. Reducer is the prime mover with an independent closed between the work gear to reduce speed and to increase torque. In addition, in some occasions, there are devices used for growth, and known as the accelerator. When the motor output shaft speed input from the initiative, the drive pinion rotation, and the drive pinion gear movement, and a large number of teeth than the gear pinion, and the speed ratio gear pinion slow, then the shaft gear ( output shaft) output, which has played the role of output slowdown. Reducer of the type, variety, many types have been formulated for the trip (the country) the subject of more than 40 kinds of reducer. Reducer is based on the type of gear used, tooth profile curve divided; reducer species is based on the use of the different needs of the reducer structure; the type of reducer in the basic structure of the tooth surface, based on hardness, transmission level, the shaft type, assembly type, installation type, connection type and other factors designed reducer different characteristics. Reducer connected with the work load of the state of more complex machines, a great impact on the speed reducer is a reducer selection and calculation of an important factor in the load reducer that is the work of the state machine (from the motives) of the load, and is usually divided into three categories: 1 uniform load;2 Medium impact load; 3 strong impact load. Mechanical aspects of the slowdown in the devices typically are:1 for the speed is relatively small, less torque on the gear drive system - ranging from a pair of gear teeth (speed) or a range of gear teeth ( variable speed). Large number of teeth for which the driving wheel, a large number of teeth used for the driven wheel. 2 for speed is relatively small, a larger torque on the gear drive system - a screw and a gear. Screw driving force with which to make decisions. If the gear teeth for N, while rotating around each gear, screw on the ring must be rotating N. 3 for the speed ratio, and torque transmission on a large turbine vice - a rod and a vortex turbine. Used to decide under which vortex dynamics. If the turbine for the number of teeth N, while rotating around each turbine, vortex must be rotating N pole lap. Air power plant is typically used for turbine Vice reducer. Its role is to: 1 deceleration at the same time increase the output torque, torque output by motor output by the ratio of reduction ratio, but bearing in mind that do not exceed the rated torque reducer. 2 The speed at the same time reducing the load inertia, the reduction of inertia than the square of speed. We can look at General Electric has a value of inertia. There is a general helical gear reducer reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloid reducer, worm gear reducer, planetary-type friction mechanical CVT machine and so on.And we have a common type of speed reducer: 1 worm gear reducer is a main feature of the reverse self-locking function, can have a larger reduction ratio, input shaft and output shaft axis is not the same, nor in the same plane . But in general larger, the transmission efficiency is not high, the accuracy is not high.2 harmonic of the harmonic drive speed reducer is to use flexible components of the elastic deformation controlled to convey movement and momentum, and volume not very high accuracy, but the drawback is the limited life Flexspline, the impact of intolerance, rigidity and metal pieces compared to poor. 3 planetary reducer compare the advantage of compact structure, the return gap small, high precision, long life, rated output torque can do a lot. Enter the speed can not be too high. However, the price a little expensive. Mechanical transmission is the use of mechanical power transmission and motion transmission. Mechanical transmission in mechanical engineering in a wide range of applications, there are a variety of forms, can be divided into two categories1 by mechanical friction between the transmission of power and movement of the friction drive, including belt drive, rope drive and friction wheel drive and so on. Easy to achieve continuously variable friction transmission, and most of them can adapt to the larger axis of the transmission distance of occasions, been able to play a buffer containing the spin and the role of the protection gear, but generally can not be used for high-power transmission of the occasion, there is no guarantee that an accurate the transmission ratio. 2 items by active engagement with the follower, or through transmission of power or middleware meshing engagement campaign drive, including the gear drive, chain drive, screw drive and harmonic drive and so on. Meshing can be used for high-power transmission of the occasions, the exact transmission ratio, but the general requirements for the manufacture of high precision and accuracy of the installation. The form of mechanical transmission is divided into: friction drive, chain drive, gear drive, belt drive, under vortex turbine drive, ratchet drive, the crankshaft connecting rod drive, pneumatic drive, hydraulic transmission (hydraulic plane), universal joint transmission,steel transmission (the most widely elevator) drive coupling, spline drive.附件 2:外文資料翻譯譯文齒輪的特點(diǎn)和作用摘要

在傳播交叉的設(shè)計(jì),將成為新的傳播動(dòng)產(chǎn)文中提到的發(fā)展的重要趨勢(shì)。就是兩個(gè)齒輪嚙合齒輪使用各種機(jī)械動(dòng)力和運(yùn)動(dòng)傳遞等傳輸。根據(jù)相對(duì)位置的齒輪軸平行的圓柱子軸齒輪傳動(dòng),傘齒輪軸交叉和跨斜軸傳動(dòng)齒輪。結(jié)構(gòu)緊湊,效率高,壽命長(zhǎng)等。齒輪是指主要,直接驅(qū)動(dòng)齒輪,運(yùn)動(dòng)和動(dòng)力傳輸設(shè)備。 在所有的機(jī)械傳動(dòng),使用最廣泛的設(shè)備可用于運(yùn)動(dòng)之間轉(zhuǎn)移和權(quán)力的任何兩個(gè)軸。 齒輪的特點(diǎn)是:齒輪傳動(dòng)平穩(wěn),傳動(dòng)比準(zhǔn)確,可靠,效率高,壽命長(zhǎng),權(quán)力運(yùn)行,速度和尺寸范圍。例如,傳輸功率小 ,

在減速的同時(shí)提高輸出扭矩,扭矩的電機(jī)由減速比比輸出輸出,但要注意不超過(guò)額定扭矩減速的影響。 2 速度 , 同時(shí)減少負(fù)載慣性時(shí)間,比速度平方慣性減少。我們可以看看通用電氣有一個(gè)慣性的價(jià)值。人們普遍斜齒輪減速機(jī)減速機(jī)(包括平行軸斜齒輪減速機(jī),蝸輪蝸桿減速器,錐齒輪減速機(jī)等),行星齒輪減速機(jī),擺線針輪減速機(jī),蝸輪減速器,行星齒輪式機(jī)械無(wú)級(jí)變速機(jī)摩擦等。 我們有一個(gè)共同的速度型減速器: 1 蝸輪蝸桿減速機(jī)是一種相反的自我的主要特色,鎖定功能,可以有較大的減速比,輸入軸和輸出軸軸是不一樣的,也不在同一平面上。但在一般較大,傳動(dòng)效率不高,精度不高。 2 諧波傳動(dòng)減速器諧波是利用靈活的組件控制轉(zhuǎn)達(dá)運(yùn)動(dòng)和彈性變形的勢(shì)頭,交易量不大,精度高,但缺點(diǎn)是柔輪的有限的生命,不容忍,剛度和金屬件的影響比較差。輸入速度不能太高。3 行星減速比較緊湊的結(jié)構(gòu),回報(bào)差距小,精度高,壽命長(zhǎng),優(yōu)勢(shì)額定輸出扭矩可以做很多事情。然而,價(jià)格有點(diǎn)貴。 機(jī)械傳動(dòng)是機(jī)械動(dòng)力傳動(dòng)和運(yùn)動(dòng)傳輸。在機(jī)械工程機(jī)械傳動(dòng)中的應(yīng)用非常廣泛,有各種形式,可以分為兩類:(1) 機(jī)械摩擦之間的權(quán)力和摩擦傳動(dòng)運(yùn)動(dòng)的傳播,包括皮帶驅(qū)動(dòng),繩驅(qū)動(dòng)器和摩擦輪傳動(dòng)等。容易實(shí)現(xiàn)無(wú)級(jí)變速摩擦傳動(dòng),其中大部分可以適應(yīng)不同場(chǎng)合的傳輸距離較大的軸,可以播放緩沖區(qū)包含旋轉(zhuǎn)和防護(hù)裝備的作用,但一般不能用于高的電力傳輸?shù)膱?chǎng)合,也不能保證精確的傳動(dòng)比。 通過(guò)與追隨者,或通過(guò)權(quán)力或中間件嚙合接觸運(yùn)動(dòng)驅(qū)動(dòng)器傳輸,包括齒輪傳動(dòng),鏈傳動(dòng),螺桿驅(qū)動(dòng)和諧波傳動(dòng)等積極參與(2) 項(xiàng)目。嚙合可用于高場(chǎng)合輸電,確切的傳動(dòng)比,但高的精度和安裝精度制造的一般要求。 在機(jī)械傳動(dòng)形式分為:摩擦傳動(dòng),鏈傳動(dòng),齒輪傳動(dòng),帶傳動(dòng)渦輪機(jī)驅(qū)動(dòng)下的旋渦,棘輪驅(qū)動(dòng)器,曲軸連桿驅(qū)動(dòng)器,氣動(dòng)傳動(dòng),液壓傳動(dòng)(液壓機(jī)),萬(wàn)向節(jié)傳動(dòng),鋼傳輸(最廣泛的電梯)驅(qū)動(dòng)器的耦合,花鍵驅(qū)動(dòng)器
