对大型齿轮加工设备的设想

A tentative idea about tbc equipment for ma-chining heavy duty gear

本文所构思的新机型是工件不动，机床趴在齿轮上并绕其转动完成加工，故可大幅度降低设备制造成本。

The new modeled machine plotted inthis paper is that the workpiece stayed immovable andthe machining process is finished wi th the machine ro-tating around the workpiece. Thus the cost of mariufac-turing the eq uipment can be reduced to a big range.
