摘要

在现代机械制造工业中，齿轮是一种制造机器的重要零件，齿轮传动机构也是在各种机构中应用最为广泛的一种传动机构。它依靠轮齿齿廓直接接触来传递空间任意两轴间的运动和动力，并具有传递功率范围大、传动效率高、传动比准确、使用寿命长、工作可靠等优点。因此，齿轮应用极为广泛，齿轮的需求量也日益增加。于是，滚齿机（用来加工齿轮的机床）则更为重要。
本说明书描述了滚齿机在齿轮加工领域的不可或缺的地位及发展趋势，重点介绍了Y318滚齿机主传动的设计计算。
    本书从介绍课题研究的主要内容和滚齿机的的现状、未来的发展趋势入手，分析比较了滚齿机的多种方案设计，找出最佳方案，并对滚齿机主传动部分进行设计计算。
Y318：普通滚齿机，能加工直齿和斜齿圆柱齿轮、蜗轮及短花键轴，适于单件、小批或成批生产齿轮的工厂使用。机床结构优良，刚性强，热变形小，能承受较高速度的切削负荷，精度良好，操作方便，调整简单。加工齿轮时，机床可按顺铣或逆铣方式工作。机床带有自动停机机构、安全装置及自动润滑系统，可以根据用户要求配置进口液压元件或用于滚切蜗轮的切向刀架。

Abstract

In modern machinery manufacturing industry, the gear is an important manufacturing machines spare parts, gear drive mechanism is also in a variety of institutions most widely used as a transmission mechanism.It relies on direct contact with gear tooth profile to convey the space of arbitrary two-axis movement of the shoulders and power, and transmission of power with range, high transmission efficiency, transmission than accurate, long life, reliable and so on. Therefore, the application of gear has a wide range of gear is also increasing demand. Gear tooth surface for processing of machine tools, machine tool called Gear. Gear Machine machine building industry is an important technology and equipment. Therefore, the application of a wide range of gears, gear increasing demand. Thus, the hobbing machine (the machine used for processing gear) is more important
The manual describes the gear hobbing process in the field of the status of an indispensable and development trends, focusing on the main drive gear-hobbing machine Y315 design and calculation.
This book from the research introduced the main contents and status of the hobbing machine, start the trend of future development, analysis and comparison of the hobbing machine design of a variety of programs to find the best solution, and main drive gear-hobbing machine parts design and calculation.
Y315 ：Ordinary hobbing machine can be processed straight tooth and helical gears, worm gear and the short spline shaft, suitable for one-piece, small batch or mass production of the factory gear. Excellent machine tool structure, rigidity, and thermal deformation small, can withstand higher cutting speed of the load, good accuracy, convenient operation, simple to adjust. Processing gear, the machine can be cis or milling milling inverse manner. Machine tool with automatic shutdown agencies, safety devices and automatic lubrication system can be configured according to user requirements for imports of hydraulic components or roll to the cutting knives to cut the worm.
Key words: Gears, gear machining, hobbing machine, main drive, shaft
