摘　　要：针对FA721型捻线机车头原传动部分存在的结构不够紧凑、变换齿轮为单只加对牙齿轮、齿轮数量多、捻度变换差异率大等不足之处,通过变换齿轮的重新设计、齿轮传动设计及位置安排,经过反复求解、计算及优化,设计出新的捻线机车头传动机构具有简单紧凑、齿轮数目减少、成本低、传动精准、齿轮更换方便、捻度变换差异率小的特点,而且还可以达到更大范围的捻度。FA721-type locomotives for the twisting part of the first transmission deficiencies：Compact part of the structure is not enough transmission,changing gears as a single only to increases to the teeth wheel,gear quantity,such as twist rate is high enough difference in trans formation.The redesign by changing gears,gear design and gear position arrangements.After repeated solving,calculation and optimization of the design,designing a new locomotive head twister transmission mechanism simple,compact,gear reduction in the number,low cost,preci sion transmission,gear change is more convenient,twist difference in the rate of change is small,and can reach a wider range of twist.
