目前大多数坦克炮塔方向机均采用一行星汇流排将手动与电动合二为一。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。本研究通过采用“同力面混合少齿差行星传动”技术及径向弹性补偿装置，并对系统各级传动比重新分配，使方向机的空回量约减小一半，提高了方向机的传动精度和传动效率。
At present, most of the turret turrets use a planetary bus to combine manual and electric operation. However, due to the structure and tank space constraints, the steering gear transmission ratio is basically evenly distributed, the system accuracy at all levels have an impact on system error, and therefore a large amount of empty back, transmission accuracy is low, usually above 2.5 density. In this study, by adopting the technology of “same force mixing less teeth difference planetary transmission” and radial elastic compensation device, and redistributing the transmission ratios at all levels of the system, the air return of the steering machine is reduced by about half, Transmission accuracy and transmission efficiency.
