這是一個稍微複雜的行星齒輪組，可以用來模擬行星與太陽的公轉自轉運動其中有一太陽齒輪、兩行星齒輪，它是由一個太陽齒輪，兩個行星齒輪和一個連桿組成。轉動連桿，可以使行星齒輪繞著太陽齒輪轉動。太陽齒輪本身不旋轉，因此相對旋轉可以使兩個行星齒輪自轉。 This is a slightly complicated planetary gear set, it can be used to simulate the revolution of a planet around its sun. It contains one sun gear and two planet gears, pieced together by a link. Turning the link will rotate the planet gears around the sun gear while the sun gear remains stationary, thus the relative rotation will cause the planet gears to revolve around itself.
