四連桿與正齒輪對
Four-bar Linkage and Spur Gear

可視為四連桿機構,手把輸入旋轉運動於小齒輪,小齒輪轉動大齒輪。用兩個連桿固定連接齒輪,可以觀察齒輪的相對運動,我們可以將之視為四連桿機構。


We can view this mechanism as a four-links system. When we input a revolution motion to rotate the small gear by the handle, and then the small gear will drive the large gear into ration. Use two links to connect the two gears, and we can see the relative motion between the two gears. We can view this mechanism as a four-links system.
