滚齿机机床总体传动床身零件结构设计
摘要：齿轮加工机床是一种技术含量高且结构复杂的机床。滚齿机又是齿轮加工机床中应用最为广泛的一种，滚齿机主要是用于加工圆柱齿轮和蜗轮的。
滚齿机床身为箱形结构，与底座铸成一个整体，左上部是方形导轨，留安放工作台之用；右上部是用来固定刀架、立柱；床身内部安装差动机构；床身后端连出分齿挂轮架；背面为主传动牙箱；左面底盘为冷却箱；右面底盘为润滑油箱；主电动机和冷却电动机都安装在床身上，方形导轨中间装一丝杆供移动工作台之用，分度挂轮架处的手柄供铣正齿轮或者斜齿轮时操纵使用。
差动机构是用来加工斜齿轮的，分析了差动机构的组成原理，并进行了相应的设计计算，确定了其结构形状与参数。
这次设计是在传统的设计思路上对原有产品的改造，力求满足强度、刚度、经济性、工艺性等方面的要求。

Design of the Lathe Bed Cellular Construction of the Gear-hobbing Machine
Abstract: The gear finishing lathe is one kind of technical content high also the structure complex engine bed. The gear-hobbing machine also is a machine equipment which is applies the most widespread, the gear-hobbing machine mainly is uses in processing the cylindrical gears and the worm gear.
The body of gear-hobbing machine is box shape structure, casts a whole with the foundation upside, the left is the square shape of guide rail, remains places using of the work table; Right upside is uses for the immovable support of the column; The interior of the body installs the differential motion organization; Behind the body is main transmission gear-box; Back transmission is tooth box, in left side of it is a cooling tank; the right side of it is lubricating-oil tank; The main motor and the cooling electric motor all are installed on the lathe bed, among the square shape guide rail installs a lead screw to move the work table, divides the swing frame gear place handle for when milling spur gear or the helical gear operates the use.
The differential device is uses for to process the helical gear, analyzed the differential device composition principle, carried on the corresponding design calculation, and determined its structure shape and the parameter.
This design improves product transformation on the basic of traditional design, makes effort to satisfy the request as intensity, rigidity, efficiency, process.
Key words: Gear-hobbing machine; assembling structure of the body; Differential motion mechanism
