摘　　要：针对传统零差速电传动存在零轴导致结构尺寸偏大,转向分路需采用定轴齿轮传动汇流的问题,介绍了一种可实现同轴布置的零差速电传动方案,并分析了同轴零差速传动原理和特定参数关系。然后,针对该同轴零差速传动须多个行星排耦合并为非对称结构,行星传动参数和配齿设计困难,提出了采用分式表达并基于履带车辆总体参数进行行星排特征参数(k值)设计的思路,并创新设计了行星排“分式拆分”配齿方法,解决了行星排特别是WW型2k-H行星排需依据确切k值精确配齿问题。该方法简单,易操作,经实际使用验证其结果满足工程需求,具有推广应用价值。Since the traditional zero-differential electric transmission has large structure and the fixed axis gear is adopted for confluence in the steering shunt,in this article,a scheme of co-axial zero-differential electric transmission is worked out,and the relationship between the principle of co-axial zero-differential transmission and the specific parameters is explored.Then,since the coaxial zero-differential electric transmission requires an asymmetric multi-planet gear-coupling structure,and it is difficult to identify both the planetary-transmission parameters and the teeth-matching design,the idea of adopting the fractional expression and working out the characteristic parameters(k value)of planet gear based on the overall parameters of tracked vehicles is proposed.The“fractional splitting”of teeth matching for planet gear is introduced,which solves the accurate teeth-matching of planet gear,especially the WW 2k-H planet.This method is simple and easy to operate.The results of practical application prove that this method meets the engineering requirements,which is suitable for wide application.
