【正文】 wide gap between international standards . 改革開放以來，我國引進(jìn)一批先進(jìn)加工裝備，通過引進(jìn)、消化、吸收國外先進(jìn)技術(shù)和科研攻關(guān)，逐步掌握了各種高速和低 Since reform and opening, China introduced a number of advanced processing equipment, through the introduction, digestion and absorption of foreign advanced technology and scientific research, and gradually master a variety of highspeed and low 速重載齒輪裝置的設(shè)計制造技術(shù)。.Super heavy duty gear device design and manufacturing technology. 材料和熱處理質(zhì)量及齒輪加工精度均有較大提高，通用圓柱齒輪的制造精度可從JB179－60的8－9級提高到GB10095－88的6級，高速齒輪的制造精度可穩(wěn)定在4－5級。 Material and heat treatment quality and precision are both better gear, general manufacturing precision gear from JB1796039。s 89 to improve to GB1009588 Grade 6 class, highspeed precision gear manufacturing stable at 45 level. 部分減速器采用硬齒面后，體積和質(zhì)量明顯減小，承載能力、使用壽命、傳動效率有了較大的提高，對節(jié)能和提高主機(jī)的總體水平起到很大的作用。 Part of the reducer with hardened, the volume and quality of the significantly reduced load capacity, life has been greatly improved transmission efficiency, energy conservation and improve the overall level of the host played a significant role. 我國自行設(shè)計制造的高速齒輪減（增）速器的功率已達(dá)42000kW ，齒輪圓周速度達(dá)150m/s以上。 Design and manufacture our own highspeed gear reduction (increase) the powerspeed device has reached 42000kW, gear circumference speed 150m / s or more. 但是，我國大多數(shù)減速器的技術(shù)水平還不高，老產(chǎn)品不可能立即被取代，新老產(chǎn)品并存過渡會經(jīng)歷一段較長的時間。 However, the majority of our technical level is not high speed reducer, the old product could not immediately be replaced by the coexistence of old and new products will experience a longer transition time. 減速機(jī)的分類:Reducer Category: 減速機(jī)是一種相對精密的機(jī)械，使用它的目的是降低轉(zhuǎn)速，增加轉(zhuǎn)矩。 Reducer is a relatively sophisticated machine, use its purpose is to reduce speed and increase torque. 它的種類繁多，型號各異，不同種類有不同的用途。Its wide range of different models, different types have different purposes. 減速器的種類繁多，按照傳動類型可分為齒輪減速器、蝸桿減速器和行星齒輪減速器；按照傳動級數(shù)不同可分為單級和多級減速器；按照齒輪形狀可分為圓柱齒輪減速器、圓錐齒輪減速器和圓錐－圓柱齒輪減速器；按照傳動的布置形式又可分為展開式、分流式和同軸式減速器。 Reducer wide variety of drive types can be divided according to gear reducer, worm reducer and the planetary gear reducer。 in accordance with the transmission of different series can be divided into single and multistage reducer。 can be divided into cylindrical shape in accordance with gear device, and the conical bevel gear reducer gear reducer。 in accordance with the layout of the drive can be divided into expansion, Split and coaxial reducer. 以下是常用的減速機(jī)分類：The following are monly used reducer Category: ⑴擺線針輪減速機(jī) ⑴ cycloid reducer ⑵硬齒面圓柱齒輪減速器 ⑵ hardened cylinder gear reducer ⑶行星齒輪減速機(jī) ⑶ planetary gear reducer ⑷軟齒面減速機(jī) ⑷ soft tooth surface reducer ⑸三環(huán)減速機(jī) ⑸ ring reducer ⑹起重機(jī)減速機(jī) ⑹ Crane Reducer ⑺蝸桿減速機(jī) ⑺ worm reducer ⑻軸裝式硬齒面減速機(jī) ⑻ hardened shaftmounted reducer ⑼無級變速器 ⑼ CVT Worm gear reducer with the main characteristics of the reverse selflocking feature, you can have a larger reduction ratio, input shaft and output shaft is not in the same axis, not in the same plane. But generally larger, transmission efficiency is not high, accuracy is not high. Harmonic harmonic drive gear unit is controlled using the elastic deformation of flexible ponents to pass the motion and power, small size, high accuracy, but the disadvantage is the limited life of the flexible wheel, impatience impact, rigid pared with the metal pieces difference. Input speed can not be too high. Planetary reducer pare the advantage of pact structure, the return gap and high precision, long life, rated output torque can be done much, but the price a little expensive. Features and gear reducer role: In the current campaign for the transmission power and the institutions, the gear a wide range of applications in almost all the transmission systems of all kinds of machinery can see traces of it from the transport ships, cars, motorcycles, construction of heavy equipment and machinery used in industrial processing machinery and automated production equipment, to everyday mon household appliances, watches and so on. its application from the major power transmission work, to small load transfer can all see the exact point of the gear unit application, and in industrial applications, the gear reduction and increased torque with the feature, so widely used in the speed and torque conversion device. Power transmission gear is a body, in applications that require high torque and high speed of places do not use to it. For example: conveyor belt, mixers, winches, closed machine, automatic special machine ..., with the industry39。s development and factory automation, the use of reducer growing demand. There are many ways slow, but the most monly used method is based on gear to slow down, can reduce space and lower cost, they have also called reducer gear box (Gear Box). Usually some gear box bination, due to gear box itself has no power, you need to drive ponent to drive it, which can be motordriven ponents, such as engine or steam engine. The purpose of using the largest gear is the following: 1. power transmission 2. get a speed of 3. for a larger torque. But in addition to gear machines, developed by the Kamo Seiko sphere reducer, providing another key value, that is, highprecision drive, and high transmission efficiency, the new drive for the landmark structure. Reducer situation at home and abroad: Status of foreign reducer Gear in all walks of life are very widely used with, is an indispensable mechanical transmission device. Current Reducer widespread bulky, heavy, or the transmission ratio and mechanical efficiency is too low. Reducer abroad to Germany, Denmark and Japan, leading, in particular in terms of materials and manufacturing processes dominate reducer good reliability and long service life. But its form is still scheduled to drive the main shaft gear, size and weight problems, has not resolved. Recently reported that Sumitomo Heavy Industries of Japan developed the FAtype highprecision reducer, the United States AlanNewton pany developed XY reducer, the drive principle and structure similar to this pro
