【正文】 速器技術(shù)有了很大的發(fā)展。(2)通過對二級齒輪減速器的設(shè)計，使我們掌握了機械零件、機械傳動裝置或簡單機械的一般設(shè)計步驟和方法，培養(yǎng)了我們理論聯(lián)系實際的設(shè)計思想及獨立、全面科學(xué)的工程分析與設(shè)計能力。 選題的意義本論文主要內(nèi)容是對二級齒輪減速器進行設(shè)計計算，是對我們即將畢業(yè)走向工作崗位的有一次全面的、規(guī)范的機械設(shè)計能力的綜合訓(xùn)練。隨著工業(yè)快速的發(fā)展和工廠自動化程度的日益加劇，減速器的需求量也會大大增長。其可以很好的實現(xiàn)動力的傳遞，獲得某一速度和獲得較大的扭矩，效率十分之高，非常之準(zhǔn)確可靠。傳輸機生產(chǎn)線的裝置最常用的就是螺旋傳輸機傳動裝置中的以及圓柱齒輪減速器。隨著現(xiàn)代工業(yè)突飛猛進地發(fā)展，一般的速度已經(jīng)無法滿足快速工業(yè)生產(chǎn)的要求，于是就開發(fā)了利用減速器的傳輸機生產(chǎn)線，它能夠很好的提高作業(yè)人員和設(shè)備工裝的效率，有效的降低成本，提高生產(chǎn)能力。Analysis；
