船用齿轮传动系统的设计及分析（本科毕业论文设计）
摘 要
齿轮传动是工程中应用最广泛的一种机械传动，可传递平行轴、相交轴和交错轴之间的旋转运动。进入20世纪以来，齿轮技术有了飞速的发展，现代设计方法开始应用，齿轮传动的形式也愈发丰富和多样。齿轮传动的主要特点有：传动效率高、功率范围大、传动比稳定、工作安全可靠、使用寿命长等。
本实用新型船用齿轮箱属于对现有技术的一种变革，它保持了结构简单、紧凑，使用方便、安全可靠等优点，并使船舶的动力传动系统在完全水平安装时，与齿轮箱的输出轴相连的船舶尾轴能获得一定角度的入水角，从而使安装性能有较大提高，减少了船舶的传动系统受船舶空间约束；在增加微动装置后还能实现船舶螺旋浆的微速转动。本文的主要研究内容如下：
对该新型船用齿轮箱的主要组成、基本结构及传动原理进行了分析，在此基础上对该齿轮箱进行了强度分析、轴的设计、受力分析、轴承校核以及总体设计；利用AUTOCAD绘出了船用齿轮箱中主要零件的零件图，根据各零件图绘出了齿轮箱的装配图；利用PRO/E建立了该齿轮箱各零件三维实体几何模型；并进行了虚拟设计。

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
