但由于受到结构及坦克空间约束,方向机的传动比基本上均匀分配,系统各级精度均对系统误差产生影响,因而空回量大、传动精度低,通常在2.5密位以上。
Limited by the structure and space in tank , basically , the transmission ratio distributes uniformly . So each precision grade has effect on system error . The backlash is great and the transmission precision is low , usually over 2.5 mil .
