凸轮驱动器和定时齿轮涵盖的范围。
对于采用定时齿轮皮带，这是一个非常经济而可行的做法(前提条件是TBR很短，而且不做超过500英里的跨海飞行)。
As for using a timing belt gear, this is very economical and feasible if you respect a short TBR... and do not plan to cross 500 miles of sea.
对带有预定时标齿轮四杆刚体导引机构生成进行了数学描述。
Mathematic description of generation of rigid body geared four bar guidance linkage with prescribed timing is given.
由于DAC和齿轮减速比都影响着伺服系统的开环增益，当系统开环增益一定时，DAC位数的实际作用和减速比的选择相互限制，在设计雷达伺服系统中需注意。
When the open-loop gain of servo system is determined, the selection of DAC resolution and gear ratio is restricted each other and should be paid much attention in the design of servo system.
