緒論
　　　田宮行星齒輪箱是由一個小直流電機驅(qū)動的，該電機在3V，1A直流電下以每分鐘大約10500轉(zhuǎn)的速度運行。最大速比1：400。輸出速度大約為26rpm。齒輪箱內(nèi)含四個行星齒輪傳動副，兩個1：4的，兩個1：5的，他們之間可以任意搭配。該齒輪箱不僅對小的機械機構(gòu)有著好的驅(qū)動力，還樹立了行星齒輪系的典型。齒輪箱體是設計優(yōu)良的塑料箱，用很少的工具大約在1小時之內(nèi)就可以裝配完成，其詳細來源見參考文獻。
　　　首先，讓我們回顧一下齒輪的基礎(chǔ)知識，并且對行星齒輪系的原理進行分析。

Introduction
　　　The Tamiya planetary gearbox is driven by a small DC motor that runs at about10,500 rpm on 3.0V DC and draws about 1.0A. The maximum speed ratio is 1:400, giving an output speed of about 26 rpm. Four planetary stages are supplied with the gearbox,two 1:4 and two 1:5, and any combination can be selected. Not only is this a good drive for small mechanical applications, it provides an excellent review of epicyclic gear trains. The gearbox is a very well-designed plastic kit that can be assembled in about an hour with very few tools. The source for the kit is given in the References.
　　　Let's begin by reviewing the fundamentals of gearing, and the trick of analyzing epicyclic gear trains.
