【摘要】：隨著航空、航天、機(jī)器人、自動(dòng)化、船舶、車輛、武器裝備等工程領(lǐng)域事業(yè)的迅速發(fā)展，對(duì)其傳動(dòng)件及系統(tǒng)的運(yùn)動(dòng)精度、回程誤差的要求愈加嚴(yán)格。而現(xiàn)有的各種減速器已不能滿足重要裝備的發(fā)展要求。鑒于此，重慶大學(xué)機(jī)械傳動(dòng)國(guó)家重點(diǎn)實(shí)驗(yàn)室王家序教授等發(fā)明了一種濾波減速器（專利號(hào)：ZL201010104359.5），具有高剛度、小體積、輕量化、加工方便等優(yōu)點(diǎn)，并能通過(guò)軸向移動(dòng)方便地實(shí)現(xiàn)側(cè)隙的調(diào)整，特別適用于某些對(duì)回差要求嚴(yán)格的精密傳動(dòng)中，具有廣闊的應(yīng)用前景。本文針對(duì)該新型變厚齒輪少齒差行星減速器開(kāi)展設(shè)計(jì)研究，旨在提高該減速器的回差精度，改善其傳動(dòng)性能。本文研究的主要內(nèi)容可以概況如下： ①在明確傳動(dòng)裝置技術(shù)要求特別是接口尺寸要求下，進(jìn)行傳動(dòng)裝置的結(jié)構(gòu)設(shè)計(jì)：包括對(duì)各齒數(shù)進(jìn)行合理分配，并計(jì)算其幾何尺寸；校驗(yàn)其重合度、大端齒頂厚、齒廓重迭干涉以及實(shí)際頂隙。 ②基于三維設(shè)計(jì)軟件SolidWorks，研究變厚齒輪齒廓曲面的生成方法，建立傳動(dòng)裝置各零部件實(shí)體模型并進(jìn)行虛擬裝配與干涉分析。將裝配模型數(shù)據(jù)導(dǎo)入到ADAMS環(huán)境中，通過(guò)定義各種轉(zhuǎn)動(dòng)副、約束副和接觸副，建立起傳動(dòng)裝置的虛擬樣機(jī)模型，通過(guò)使用STEP函數(shù)對(duì)虛擬樣機(jī)定義運(yùn)動(dòng)和施加載荷并進(jìn)行運(yùn)動(dòng)仿真，得出輸出齒輪的轉(zhuǎn)速隨時(shí)間的變化曲線圖，求出虛擬樣機(jī)的傳動(dòng)比，并與理論值進(jìn)行比較；得出嚙合力的時(shí)域曲線圖和頻域曲線圖，并對(duì)嚙合頻率進(jìn)行分析。 ③在總結(jié)齒輪傳動(dòng)回差基本理論的基礎(chǔ)上，根據(jù)變厚齒輪的特點(diǎn)推導(dǎo)變厚齒輪嚙合側(cè)隙變化量與軸向調(diào)隙量之間的關(guān)系式。進(jìn)而基于概率統(tǒng)計(jì)的方法對(duì)內(nèi)嚙合變厚齒輪副各回差來(lái)源進(jìn)行定量分析，建立內(nèi)嚙合變厚齒輪副回差計(jì)算模型。在此基礎(chǔ)上，建立該新型側(cè)隙可調(diào)式濾波傳動(dòng)裝置的回差計(jì)算模型。 ④基于變厚齒輪副內(nèi)、外齒輪的齒廓曲面方程和齒輪嚙合理論，推導(dǎo)內(nèi)嚙合變厚齒輪副的嚙合模型，并在此基礎(chǔ)上，，推導(dǎo)出考慮輪齒彎曲變形影響的齒面接觸應(yīng)力分布模型，并推廣到多齒接觸的情況，與有限元分析結(jié)果進(jìn)行了比較。根據(jù)計(jì)算結(jié)果對(duì)輪齒進(jìn)行了齒端修形研究。
[Abstract]:With the rapid development of aeronautics, spaceflight, robot, automation, ship, vehicle, weapon equipment and other engineering fields, the requirements for the motion accuracy and return range error of its transmission parts and systems become more and more strict. However, the existing reducers can not meet the requirements of the development of important equipment. In view of this, Professor Wang Jiapu and others in the State key Laboratory of Mechanical Transmission of Chongqing University have invented a filter reducer (Patent No.: ZL201010104359.5), which has the advantages of high stiffness, small volume, lightweight, convenient processing, etc. It can adjust the clearance conveniently by axial movement, especially in some precision transmission with strict return difference, and has a broad application prospect. In this paper, the design and research of the new type planetary reducer with less tooth difference are carried out in order to improve the accuracy of the reducer and improve its transmission performance. The main contents of this paper can be summarized as follows: 1 under the condition of defining the technical requirements of the transmission device, especially the requirements of the interface size, the structural design of the transmission device is carried out: including the reasonable distribution of the number of teeth, And calculate its geometry size, check its coincidence degree, large end tooth top thickness, tooth profile overlap interference and actual top gap. 2 based on 3D design software SolidWorks, the method of generating tooth profile surface of thickened gear is studied. The solid model of each part of the transmission device is established and virtual assembly and interference analysis are carried out. The assembly model data is imported into Adams environment. By defining various rotating pairs, constraint pairs and contact pairs, the virtual prototype model of the transmission device is established. By using step function, the motion and load of the virtual prototype are defined, and the motion simulation is carried out. The speed curve of the output gear with time is obtained, the transmission ratio of the virtual prototype is calculated, and compared with the theoretical value, the time domain curve and frequency domain curve of the meshing force are obtained. On the basis of summarizing the basic theory of gear transmission return difference, the relationship between the change of meshing clearance and axial clearance of thickened gear is deduced according to the characteristics of thickened gear. Then based on the method of probability and statistics, the source of return difference of internal meshing and thickening gear pair is quantitatively analyzed, and the calculation model of return difference of internal meshing and thickening gear pair is established. On the basis of this, the calculation model of the return difference of the new type of backlash adjustable filter transmission is established. 4 based on the tooth profile surface equation of the inner and outer gears and the meshing theory of the gears, The meshing model of internal meshing and thickening gear pair is derived. On this basis, the tooth surface contact stress distribution model considering the influence of gear tooth bending deformation is derived, which is extended to the case of multi-tooth contact, and the results are compared with the finite element analysis results. According to the calculation results, the tooth end modification is studied.
