cog wheel

基本解釋

One cog-wheel engages with another.
一齒輪與另一齒輪嚙合。
One cog -wheel engages with another.
那兩個齒輪嚙合后機器就轉動了。
Depending on the requirements of the control system, the number of teeth on the cog wheel is defined to allow a resolution of approximately one pulse per degree of crankshaft revolution.
鑒于控制系統的要求，齒輪齒數的確定應與機軸旋轉一度產生大約一脈沖的分辨率來確定。

And understand that you, however, are a small cog in a big wheel.
