船用齒輪傳動(dòng)系統(tǒng)的設(shè)計(jì)及分析（本科畢業(yè)論文設(shè)計(jì)）
摘 要

齒輪傳動(dòng)是工程中應(yīng)用最廣泛的一種機(jī)械傳動(dòng)，可傳遞平行軸、相交軸和交錯(cuò)軸之間的旋轉(zhuǎn)運(yùn)動(dòng)。進(jìn)入20世紀(jì)以來(lái)，齒輪技術(shù)有了飛速的發(fā)展，現(xiàn)代設(shè)計(jì)方法開(kāi)始應(yīng)用，齒輪傳動(dòng)的形式也愈發(fā)豐富和多樣。齒輪傳動(dòng)的主要特點(diǎn)有：傳動(dòng)效率高、功率范圍大、傳動(dòng)比穩(wěn)定、工作安全可靠、使用壽命長(zhǎng)等。
本實(shí)用新型船用齒輪箱屬于對(duì)現(xiàn)有技術(shù)的一種變革，它保持了結(jié)構(gòu)簡(jiǎn)單、緊湊，使用方便、安全可靠等優(yōu)點(diǎn)，并使船舶的動(dòng)力傳動(dòng)系統(tǒng)在完全水平安裝時(shí)，與齒輪箱的輸出軸相連的船舶尾軸能獲得一定角度的入水角，從而使安裝性能有較大提高，減少了船舶的傳動(dòng)系統(tǒng)受船舶空間約束；在增加微動(dòng)裝置后還能實(shí)現(xiàn)船舶螺旋漿的微速轉(zhuǎn)動(dòng)。本文的主要研究?jī)?nèi)容如下：
對(duì)該新型船用齒輪箱的主要組成、基本結(jié)構(gòu)及傳動(dòng)原理進(jìn)行了分析，在此基礎(chǔ)上對(duì)該齒輪箱進(jìn)行了強(qiáng)度分析、軸的設(shè)計(jì)、受力分析、軸承校核以及總體設(shè)計(jì)；利用AUTOCAD繪出了船用齒輪箱中主要零件的零件圖，根據(jù)各零件圖繪出了齒輪箱的裝配圖；利用PRO/E建立了該齒輪箱各零件三維實(shí)體幾何模型；并進(jìn)行了虛擬設(shè)計(jì)。

Gear is the most extensive project of a mechanical transmission, parallel shaft transmission, axle and staggered intersection between the axis of rotation. Since the beginning of the 20th century, gear technology with the rapid development and application of modern design began, in the form of gear transmission also become
more rich and diverse. Drive the main features are: efficient transmission, power range, transmission ratio stability, work safe, reliable, long life, and so on.
The utility model marine gear box belonging to a transformation of existing technologies, it has maintained a simple, compact, easy to use, safe and reliable, and other advantages, and the ship's power transmission system in all levels of installation, and the output of gear box Shaft connected to the ship's tail shaft can be certain angle into the water angle, so that the installation of a larger increase, a decrease of the ship's transmission system by the space ship bound to increase in micro-devices can achieve the ship after the pulp-speed spiral rotation. The main study as follows:
The new ship the main gear box composition, structure and basic principles of transmission were analyzed, on the basis of the gear box for the strength of the shaft design, mechanical analysis, design and bearing checking the use of AUTOCAD Marine gear box drawn in the main parts of the parts plans, according to various parts of the gear box drawn map of the assembly; using PRO / E to establish the gear box of parts 3D geometry model and the virtual design.


Key words: marine gear box,transmission ratio, reducer, AUTOCAD, PRO / E
