摘要：为提高某大缸径柴油机齿轮传动系统的可靠性，采用EXCITE Timing Drive软件建立齿轮传动系统和配气机构动力学模型，在考虑发动机转速、负载波动等因素影响的情况下，分析齿侧间隙、发动机附件负载和齿宽对齿轮强度、连接可靠性、润滑特性等齿轮系统动态特性的影响。结果表明：齿侧间隙主要影响动态齿间力，负载对整条传动链的主要动态特性影响显著，齿宽主要影响齿轮系统的强度。该分析可以为发动机齿轮系统优化提供参考。

Abstract：In order to improve the reliability of the gear
transmission system for a large bore diesel engine, the dynamics model of the
gear transmission system and valve mechanism are established by the EXCITE
Timing Drive software. Considering the influence of engine speed, load
fluctuation and other factors, the effects of gear backlash, engine accessory
load and tooth width on gear strength, connection reliability and lubrication
characteristics on gear system dynamic characteristics are analyzed. The
results show that the gear backlash factor is mainly reflected in dynamic
intertooth force. The variation of load has a significant influence on the main
dynamic characteristics of the whole transmission chain. The influence of tooth
width on gear system is mainly in strength. The analysis can provide reference
for the optimization of gear system.
