【正文】 the liberation of car only spline interface to connect to the access edge truck browser. Far can not meet the needs of a variety of dedicated devices. Modified to fit the advantages of the depot, that is a dedicated device. A converted small depot in the production of dozens of units, hundreds more cars, not the ability and energy to produce a dedicated device adapted to take power, and can only rely on the chassis parts and ponents manufacturers. Production gearbox manufacturers, due to take the necessary force varieties, specifications, requirements vary, with the total number less, there is no volume, value and small, good production. No attention to the gearbox plant, large quantities only in high universality of the dump truck from a limited ability to make a device changes, or modification to the depot itself, lead to a reduction in functionspecific devices. For example, check our low speed, power shortage, special features, such as defects in 本科生畢業(yè)設(shè)計(jì)（論文） 33 action a long time. In order to achieve satisfaction with the special features, modification depot looking for some manufacturers have taken power, and the end result of a small number of varieties, the difference between input and output, and profit do not want to do, or just can not do quality assurance. There is also a factor, the modern automobile products to speed up the rate of replacement, the engine power train, gearbox update soon, two or three years there is the introduction of new products, check our updated browser, not a professional production from a small manufacturer of Power can not keep up the pace of development. It is understood that before there is a check of Power Research Institute, Hubei Automotive Gear Factory is a subsidiary called Yunmeng from the Institute of Power, a very high reputation at the time, only a country, after carrying out the reform disappeared. There are a number of small businesses supporting the depot for the conversion from power devices are in a certain area, supporting the production of a single species, there is no scale of imitation is only slightly modified gearbox factory products to adapt to several models. Because it is imitation, not an accurate transmission of technical parameters, such as taking power away from the center of the gear, check our gear parameters, installation size, resulting in power can not take the normal work of poor quality, short life and even give rise to transmission fight gear tooth, affecting the normal use of the gearbox. All in all, check our product is a dedicated device such vehicle chassis with a dedicated device convergence an important part of an essential, as species, quantity, value and other factors, chassis manufacturer with a dedicated depot do not want more input, so that there a business, requires the development of a professional third party39。 bzw=m*kczw。 rz=.*dz。 a=*pi/180。 本科生畢業(yè)設(shè)計(jì)（論文） 30 k1=1. 5。 zw=[z1] zzw=[z3]。 f=sqrt(fc^2+fs^2) 2 齒輪校核程序 Temax=450*10^3 z1=23。 Tn=Temax/z1*z2 M=sqrt(Mc^2+Ms^2+Tn^2)。 6=189。 bbo=25*pi/180。在此再一次感謝王老師，感謝您無(wú)私的付出，感覺(jué)您悉心的指導(dǎo)，獻(xiàn)上我真摯的祝福。 利用已知條件，將取力器各個(gè)重要尺寸計(jì)算出來(lái)，從實(shí)際出發(fā)，考慮到經(jīng)濟(jì)性，使用性，來(lái)設(shè)計(jì)此型號(hào)的取力器。 在灰口鐵中，由于片狀石墨的存在使其抗拉強(qiáng)度和塑性大大低于鋼材，但片狀石墨對(duì)抗壓強(qiáng)度和硬度影響不大，仍然接近于鋼材。此外， 20 CrMnTi 還具有較好的淬透性，由于合金元素鈦的影響，故在滲碳后可直接降溫淬火。 10 粗車外圓； 20 銑端面； 30 銑大端兩平面； 40 半精車外圓； 50 鉆孔（φ 6孔）； 60 磨外圓； 70 銑 內(nèi)球面（ ）； 80 去毛刺，修正； 90 最終檢驗(yàn)。 本科生畢業(yè)設(shè)計(jì)（論文） 18 第四章 主要零件加工工藝過(guò)程 取力器二軸的加工工藝過(guò)程 取力器二軸加工工藝 毛坯：棒材。=15000 (h)； 作用點(diǎn)距離 L=56 (mm)； Fr 與軸承 1 距離 L1=33 (mm)； Fr 與軸心線距離 La= (mm)； 溫度系數(shù) ft=1； 潤(rùn)滑方式 Grease=油潤(rùn)滑 ； 三、選擇軸承型號(hào) 軸承類型 BType=圓錐滾子軸承 ； 軸承型號(hào) BCode=32908； 軸承內(nèi)徑 d=40 (mm)； 軸承外徑 D=62 (mm)； 軸承寬度 B= 15(mm)； 基本額定動(dòng)載荷 C=31500 (N)； 本科生畢業(yè)設(shè)計(jì)（論文） 14 基本額定靜載荷 Co=46000 (N)； 極限轉(zhuǎn)速 (油 ) nlimy=7000 (r/min)； 四、計(jì)算軸承受力 軸承 1 徑向支反力 Fr1= (N)； 軸承 1 軸向支反力 Fa1= (N)； 軸承 2 徑向支反力 Fr2= (N)； 軸承 2 軸向支反力 Fa2= (N)； 五、計(jì)算當(dāng)量動(dòng)載荷 當(dāng)量動(dòng)載荷 P1= (N)； 當(dāng)量動(dòng)載荷 P2= (N)； 六、校核軸承壽命 軸承工作溫度 T==120 (℃ )； 軸承壽命 L10=1484 (10^6 轉(zhuǎn) )； 軸承壽命 Lh=31162 (h)； 驗(yàn)算結(jié)果 Test=合格 。 mm 扭矩 T： /= 取 1Z =40，與齒輪 2 齒數(shù) 34，中間軸齒輪齒數(shù) 34 均無(wú)公因數(shù)。 已知變速器中間軸齒輪參數(shù)： 齒數(shù)： 40； 法向模數(shù)： ； 壓力角： 20； 螺旋角： 176。所不同的是， 前置取力器是通過(guò)變速器一軸進(jìn)行取力，工作時(shí)不影響變速器的換檔。 ，重量輕。帶副箱式主要是在原取力器 基礎(chǔ)上進(jìn)一步增速或減速；單操縱雙輸出式的兩輸出可同軸也可不同軸，同一操縱機(jī)構(gòu)同時(shí)控制；雙操縱雙輸出式的兩輸出可同軸也可不同軸， 由不同的操縱機(jī)構(gòu)獨(dú)立控制。 good processing process and assembly process of. The overall structure of the form of a twoaxis, taking power from the device to a dedicated power transfer between the devices can be used mechanical transmission. Connect with Pulley. First of all, the EQ1061type vehicle in accordance with engine and transmission parameters and a dedicated device used to determine the parameters of Power from the transmission ratio, determined in accordance with the assembly of space inside edge from the center distance of two gear range, under the power transmission gear parameters taken from the two gear power devices module, pressure angle, tooth width and other parameters. Then, check our plete device assembly drawing and ponents drawing. Finally, the preparation of parts of the processing process.
