這也是屬於行星齒輪的一種，用此機構可以用少許齒輪達到極高的轉速比，手把輸入旋轉運動於轉輪，轉動連桿和齒輪。利用直斜齒輪將傳輸動力傳送至不動的齒輪，消耗輸入旋轉運動。 This is also a kind of planet gear. By using this device, a high gear ratio can be achieved with a little amount of gears. The handle inputs a revolving motion upon the wheel, turning the link and the gears. Power is consumed by transmitting the power to the stationary gear through the straight bevel gear.
