【摘要】：內(nèi)齒行星齒輪傳動(dòng)是一種相對(duì)較為獨(dú)特的齒輪傳動(dòng)方式，它具有結(jié)構(gòu)緊湊、承載能力大、傳動(dòng)比大、傳動(dòng)效率高、體積小和運(yùn)動(dòng)平穩(wěn)等優(yōu)點(diǎn)。在這些優(yōu)點(diǎn)的基礎(chǔ)上，內(nèi)齒行星齒輪減速器漸漸地被廣泛應(yīng)用到了國(guó)防、冶金、礦山、紡織、起重運(yùn)輸、輕工、化工、食品工業(yè)、儀表制造和建筑工程等各種領(lǐng)域當(dāng)中，，逐步地替代了現(xiàn)有的多級(jí)圓柱齒輪減速器，蝸桿蝸輪減速器等類(lèi)型的減速器，同時(shí)它也受到了廣大學(xué)者們的日益關(guān)注和深入的研究。 對(duì)于內(nèi)齒行星齒輪傳動(dòng)，分析內(nèi)、外齒輪嚙合力大小的變化情況以及計(jì)算轉(zhuǎn)臂軸和軸承上的受力情況，這是內(nèi)齒行星齒輪減速器產(chǎn)品設(shè)計(jì)的重要問(wèn)題之一。本文針對(duì)高速軸動(dòng)力輸入的不同情況，對(duì)內(nèi)齒板進(jìn)行了受力分析，并且得到了內(nèi)、外齒輪嚙合力大小的變化規(guī)律以及轉(zhuǎn)臂軸和軸承的受力情況。 內(nèi)齒行星齒輪減速器的運(yùn)動(dòng)設(shè)計(jì)和結(jié)構(gòu)設(shè)計(jì)也是本文的關(guān)鍵部分，對(duì)內(nèi)齒行星齒輪傳動(dòng)的傳動(dòng)比進(jìn)行了推導(dǎo)計(jì)算，列出了齒輪副參數(shù)計(jì)算的相關(guān)公式，對(duì)減速器的幾個(gè)基本參數(shù)中心距、傳動(dòng)比、內(nèi)外齒輪的齒數(shù)以及模數(shù)的確定進(jìn)行了分析，另外也對(duì)行星軸承的選擇，輸出軸和輸入軸的結(jié)構(gòu)以及內(nèi)齒板的幾何尺寸進(jìn)行了設(shè)計(jì)。 本文以整體尺寸和重量最小為目標(biāo)，充分考慮各種約束條件，采用先進(jìn)的優(yōu)化方法，對(duì)內(nèi)齒行星減速器進(jìn)行優(yōu)化設(shè)計(jì)。通過(guò)目標(biāo)函數(shù)的建立和選取合適的設(shè)計(jì)變量，以及約束條件的確定都是有多方面的因素問(wèn)題要考慮的，幾何參數(shù)，如尺寸、體積、齒廓干涉、裝配條件等；運(yùn)動(dòng)學(xué)因素，主要是傳動(dòng)比；承載能力的因素，如齒面接觸疲勞強(qiáng)度，齒根彎曲疲勞強(qiáng)度等。憑借MATLAB優(yōu)化工具箱對(duì)內(nèi)齒行星齒輪進(jìn)行了優(yōu)化設(shè)計(jì)，在滿(mǎn)足約束條件的情況之下，優(yōu)化后的內(nèi)齒行星減速器和之前的相比較，其體積有明顯的減少，這說(shuō)明在MATALB優(yōu)化工具箱的優(yōu)化工具下，這種方法是可行的，對(duì)降低生產(chǎn)產(chǎn)品成本，提高制造廠家的經(jīng)濟(jì)效益等都有相當(dāng)大的實(shí)際意義。 最后，通過(guò)對(duì)內(nèi)齒行星齒輪減速器CAD系統(tǒng)簡(jiǎn)單的開(kāi)發(fā)，通過(guò)Pro/E軟件強(qiáng)大的參數(shù)化三維建模功能，在參數(shù)化造型技術(shù)為基礎(chǔ)上建立了零件庫(kù)系統(tǒng)，通過(guò)對(duì)模板零件實(shí)行尺寸驅(qū)動(dòng)，并且實(shí)現(xiàn)了自動(dòng)生成零件，這樣有助于實(shí)現(xiàn)內(nèi)齒行星齒輪減速器設(shè)計(jì)的自動(dòng)化、可視化及部分智能化。
[Abstract]:Inner tooth planetary gear transmission is a relatively unique gear transmission mode. It has the advantages of compact structure, large bearing capacity, large transmission ratio, high transmission efficiency, small volume and stable movement. The inner gear reducer has been widely used in many fields such as national defense, metallurgy, mining, textile, lifting transportation, light industry, chemical industry, food industry, instrument manufacture and construction engineering, etc. It has gradually replaced the existing multi-stage cylindrical gear reducer, worm gear reducer and other types of reducer. At the same time, it has been paid more and more attention and in-depth research by many scholars. For the inner tooth planetary gear transmission, the change of the meshing force of the inner and outer gears and the calculation of the force on the rotating arm shaft and bearing are analyzed. This is one of the important problems in the design of the inner gear reducer. In this paper, the internal gear plate is analyzed according to the different conditions of the high speed shaft dynamic input, and the inner gear plate is obtained. The changing law of the engagement force of the outer gear and the force condition of the arm shaft and bearing. The motion design and structure design of the inner planetary gear reducer are also the key parts of this paper. The transmission ratio of the inner tooth planetary gear transmission is deduced and calculated, and the relevant formulas for the calculation of the gear pair parameters are listed. Several basic parameters of the reducer, such as center distance, transmission ratio, tooth number and modulus of internal and external gears, are analyzed. In addition, the selection of planetary bearings, the structure of output shaft and input shaft and the geometric size of inner gear plate are also designed. This paper takes the minimum size and weight as the objective, fully considers all kinds of constraints, and adopts advanced optimization method to optimize the design of the inner gear planetary reducer. Through the establishment of the objective function and the selection of appropriate design variables, The determination of constraint conditions has many factors to be considered, such as size, volume, tooth profile interference, assembly condition, kinematics, transmission ratio, bearing capacity, etc. Such as tooth surface contact fatigue strength, tooth root bending fatigue strength and so on. With the help of MATLAB optimization toolbox, the inner tooth planetary gear is optimized and designed. Under the condition of satisfying the constraint conditions, the optimized inner tooth planetary reducer is compared with the previous one. The volume is obviously reduced, which shows that this method is feasible under the optimization tools of MATALB optimization toolbox, and has great practical significance to reduce the cost of production products and improve the economic benefits of manufacturers. Finally, through the simple development of the CAD system of the inner planetary gear reducer and the powerful parameterized 3D modeling function of the Pro/E software, the part library system is established on the basis of the parameterized modeling technology. Through the dimension drive of the template parts and the automatic generation of the parts, it is helpful to realize the automation, visualization and partial intelligence of the design of the inner planetary gear reducer.
