摘　　要：根据某款V型发动机的结构形式,给出其正时链传动系统的设计方法,进行了正时链系统的结构布局、系统内链与链轮、导轨、张紧器的设计以及系统的链长计算,并建立了系统的动力学模型。仿真分析了正时链传动系统的运动轨迹、链节之间的张力、链与传动部件之间的接触力以及张紧器的张紧力。结果表明,本文设计方法是可行的,建立的正时链传动系统的动态特性分析结果满足设计要求。Based on the structure of kind of V type engine, a design method for the timing chain system was established. The overall layout, the chain, sprocket, guide rail, tensioner of the timing chain system were designed and the length of the chain system was calculated. A dynamics analysis model of the system was proposed. The trajectory and the chain tension force, the contact force between the chain and the transmission parts, and the tensioner＇s tension were analyzed. The results demonstrate that the proposed design method is reliable, and the dynamic analysis results can meet the requirement of the design. This study provides a reference for timing chain system design.
