【摘要】：擺線(xiàn)齒輪減速器在高的傳動(dòng)比時(shí),仍具有較高的傳動(dòng)效率,這是一般漸開(kāi)線(xiàn)行星齒輪減速器所不能做到的。另外在傳動(dòng)過(guò)程中,擺線(xiàn)輪主要承受的是壓應(yīng)力,而以漸開(kāi)線(xiàn)作為齒廓的輪齒主要承受剪應(yīng)力,這使得擺線(xiàn)減速器的使用壽命高于漸開(kāi)線(xiàn)。本文首先介紹了國(guó)內(nèi)外相關(guān)擺線(xiàn)齒輪減速器的發(fā)展現(xiàn)狀及其應(yīng)用,提出了開(kāi)發(fā)新型擺線(xiàn)齒輪減速器的必要性。 首先在分析了雙擺線(xiàn)齒輪傳動(dòng)的原理基礎(chǔ)上,指出其在傳動(dòng)過(guò)程中由于內(nèi)外擺線(xiàn)輪一擺的長(zhǎng)度不相等導(dǎo)致針齒在與內(nèi)外擺線(xiàn)輪嚙合的過(guò)程中存在既滾又滑的問(wèn)題。為了從根本上克服這一問(wèn)題,本文提出在滿(mǎn)足內(nèi)外擺線(xiàn)輪一擺的長(zhǎng)度相等的情況下給內(nèi)外擺線(xiàn)輪與針齒外緣疊加上小齒,將針齒與內(nèi)外擺線(xiàn)輪之間的接觸變?yōu)樾↓X與小齒之間的嚙合,這樣既可以消除原有的滑動(dòng),還可以省去針輪的保持架,有效的減少減速器的軸向尺寸與零件個(gè)數(shù)。 然后利用Mathematica軟件在內(nèi)外擺線(xiàn)輪實(shí)際齒廓上成功疊加了擺線(xiàn)小齒、圓弧小齒,并將疊加擺線(xiàn)小齒后的曲線(xiàn)坐標(biāo)值導(dǎo)出到文本文件中。使用Pro/E讀取疊加擺線(xiàn)小齒后的數(shù)據(jù)文件建立相應(yīng)的三維實(shí)體模型。使用Pro/E的參數(shù)化建模方法,在內(nèi)外擺線(xiàn)上疊加了單一的漸開(kāi)線(xiàn)小齒,建立了簡(jiǎn)單的三維實(shí)體模型,采用ADAMS進(jìn)行了運(yùn)動(dòng)學(xué)仿真驗(yàn)證了疊加漸開(kāi)線(xiàn)小齒的可行性。 參考非圓齒輪的設(shè)計(jì)方法,分析了在非圓曲線(xiàn)上疊加漸開(kāi)線(xiàn)小齒的作圖法、齒形法線(xiàn)法、解析法與折算齒形法。采用折算齒形法利用Pro/E設(shè)計(jì)了一套疊加漸開(kāi)線(xiàn)小齒的減速器三維實(shí)體模型,分別計(jì)算了內(nèi)外擺線(xiàn)輪的漸開(kāi)線(xiàn)輪齒。采用ADAMS建立了虛擬樣機(jī)進(jìn)行了運(yùn)動(dòng)學(xué)分析,驗(yàn)證了采用折算齒形法疊加漸開(kāi)線(xiàn)小齒的合理性與可靠性。 最后詳細(xì)設(shè)計(jì)了兩套疊加擺線(xiàn)小齒的減速器,詳細(xì)繪制了相應(yīng)的二維工程圖,加工出了物理樣機(jī),有效的驗(yàn)證了新減速器的可行性,為該新型減速器的進(jìn)一步研究打下了很好的基礎(chǔ)。
[Abstract]:Cycloidal gear reducer still has higher transmission efficiency when the transmission ratio is high, which can not be achieved by the general involute planetary gear reducer. In addition, in the transmission process, the cycloidal gear is mainly subjected to compressive stress, while the involute gear is mainly subjected to shear stress, which makes the cycloid reducer service life longer than involute. This paper first introduces the development and application of cycloidal gear reducer at home and abroad, and puts forward the necessity of developing new cycloidal gear reducer. Firstly, on the basis of analyzing the principle of double cycloid gear transmission, it is pointed out that in the course of transmission, the needle teeth have the problem of rolling and sliding in the course of meshing with the inner and outer cycloid gears due to the unequal length of one pendulum of the inner and outer cycloid wheels. In order to overcome this problem fundamentally, this paper proposes that the outer and outer cycloid wheel should be superimposed on the outer edge of the needle tooth on the condition that the length of the pendulum is equal to that of the inner and outer cycloid wheel. The contact between the pin tooth and the inner and outer cycloid wheel is changed into the meshing between the small tooth and the small tooth, which can not only eliminate the original sliding, but also save the cage of the pin wheel, and effectively reduce the axial dimension of the reducer and the number of parts. Then, the cycloidal teeth and circular arc teeth are successfully superimposed on the actual tooth profiles of the inner and outer cycloidal gears by Mathematica software, and the curvilinear coordinate values after the superposition of the cycloidal teeth are exported to a text file. Using Pro/E to read the data file after superposition cycloid teeth to establish the corresponding three-dimensional solid model. Using the parametric modeling method of Pro/E, a single involute tooth is superimposed on the inner and outer cycloid line, and a simple three-dimensional solid model is established. The feasibility of superimposing involute small tooth is verified by kinematics simulation with ADAMS. Referring to the design method of non-circular gear, the drawing method, tooth shape normal method, analytic method and conversion tooth form method of superimposing involute small teeth on non-circular curve are analyzed. A set of three dimensional solid model of reducer with superimposed involute teeth is designed by using Pro/E method and the involute gear teeth of inner and outer cycloidal gears are calculated respectively. The kinematics analysis of the virtual prototype was carried out by using ADAMS, and the rationality and reliability of superposition involute teeth by the method of converted tooth profile were verified. Finally, two sets of superposition cycloidal gear reducers are designed in detail, and the corresponding two-dimensional engineering drawings are drawn in detail, and the physical prototype is processed, which effectively verifies the feasibility of the new reducer. It lays a good foundation for the further research of the new reducer.
