【摘要】：可持續(xù)能源戰(zhàn)略提倡以新能源逐步取代化石燃料能源，是一種優(yōu)先發(fā)展的戰(zhàn)略。在各種新能源中，風(fēng)能目前在很多發(fā)達國家中都占有很重要的地位。隨著國際合作研究的不斷進行，各種成熟的風(fēng)能轉(zhuǎn)換技術(shù)可以逐步滿足各個相關(guān)產(chǎn)業(yè)的快速發(fā)展。風(fēng)力發(fā)電機組的研發(fā)已成為引領(lǐng)當(dāng)今社會綠色能源發(fā)展的潮流。 齒輪箱在風(fēng)電產(chǎn)業(yè)的迅速發(fā)展中起到至關(guān)重要的作用，而在對齒輪箱的設(shè)計的過程中，其最主要的傳遞動能的部件為齒輪，因此分析齒輪嚙合過程的強度并對其進行優(yōu)化是齒輪箱設(shè)計中至關(guān)重要的一步。結(jié)合風(fēng)力發(fā)電機組安設(shè)位置，將客觀因素考慮到齒輪箱設(shè)計中，對齒輪嚙合過程中的接觸應(yīng)力和齒根彎曲應(yīng)力進行分析。文中結(jié)合沈陽鼓風(fēng)機集團風(fēng)電有限公司中兆瓦級風(fēng)力發(fā)電機組增速箱設(shè)計實例，吸收國外2兆瓦風(fēng)力發(fā)電機組增速箱結(jié)構(gòu)設(shè)計技術(shù)，開發(fā)具有自主知識產(chǎn)權(quán)的風(fēng)機齒輪箱，對齒輪箱進行整體和局部研究，改進設(shè)計方案，改善齒輪傳動性能，提高齒輪承載能力和使用壽命。 本文主要的研究對象為風(fēng)力發(fā)電機組中減速箱內(nèi)一級行星輪系的行星輪和內(nèi)齒輪，運用三維立體建模技術(shù)與有限元分析方法對其進行應(yīng)力計算，并結(jié)合修形原理選擇合適的修形方法和修形參數(shù)進行修形。對按照修形方案修形后的齒輪進行應(yīng)力分析，得出有限元分析結(jié)果，確定修形可行性。本文主要研究內(nèi)容如下： （1）運用經(jīng)典接觸力學(xué)的方法，，求解齒輪嚙合過程中，齒輪的接觸應(yīng)力和齒根彎曲應(yīng)力，分別與許用接觸應(yīng)力和齒根彎曲應(yīng)力進行對比，確定齒輪箱設(shè)計合理性。 （2）運用Pro/E建立斜齒內(nèi)嚙合齒輪精確模型，利用無縫接口技術(shù)將其導(dǎo)入ANSYS中進行有限元分析，并與同樣參數(shù)下的直齒內(nèi)嚙合齒輪進行對比分析，明確了斜齒內(nèi)嚙合齒輪副改善接觸應(yīng)力的效果。 （3）對一級行星輪系中的內(nèi)齒輪進行齒廓修形，并通過有限元分析其最大接觸應(yīng)力，確定了修形后齒輪傳動性能和強度的改善情況。
[Abstract]:The sustainable energy strategy, which advocates the gradual replacement of fossil fuels with new sources of energy, is a priority development strategy. Wind energy plays an important role in many developed countries. With the development of international cooperation, All kinds of mature wind energy conversion technology can gradually meet the rapid development of various related industries. The research and development of wind turbine has become the trend of leading the development of green energy in today's society. The gearbox plays a vital role in the rapid development of wind power industry, and in the design of the gearbox, the most important part of the transmission of kinetic energy is the gear, Therefore, analyzing the strength of gear meshing process and optimizing it is a very important step in gearbox design. Considering the installation position of wind turbine, the objective factors are taken into account in the gearbox design. The contact stress and tooth root bending stress during gear meshing are analyzed. An example of the design of a megawatt wind turbine growth box in Shenyang Blower Group Wind Power Co., Ltd is presented in this paper. Absorbing the structural design technology of 2 MW wind turbine growth box from abroad, developing the fan gearbox with independent intellectual property right, carrying on the integral and local research on the gearbox, improving the design scheme, improving the gear transmission performance, Increase gear bearing capacity and service life. The main research object of this paper is the planetary gear and inner gear of the first grade planetary gear train in the deceleration box of wind turbine. The stress of the gear train is calculated by using three-dimensional modeling technology and finite element analysis method. Combined with the principle of modification, the appropriate modification method and modification parameters are selected. The stress analysis of gears modified according to the modification scheme is carried out, and the results of finite element analysis are obtained to determine the feasibility of modification. The main contents of this paper are as follows:. 1) the contact stress and tooth root bending stress of gear in meshing process are solved by classical contact mechanics method, which are compared with allowable contact stress and tooth root bending stress, respectively, and the design rationality of gear box is determined. 2) using Pro/E to establish the accurate model of helical internal meshing gear, using seamless interface technology to import it into ANSYS for finite element analysis, and comparing it with the straight tooth internal meshing gear under the same parameters. The effect of the helical gear pair on the contact stress is determined. The tooth profile modification of the inner gear in the first grade planetary gear train is carried out, and the improvement of the gear transmission performance and strength after the modification is determined by the finite element analysis of the maximum contact stress.
