圆柱齿轮分扭传动系统中弹性扭力轴系的设计与分析

Design and Analysis of the Elastic Torsion Shafting in Split Torque Transmission System of Cylindrical Gear

根据设计图样,利用Romax建立弹性扭力轴系及含弹性扭力轴系的分扭传动系统分析模型。在Romax环境下研究弹性扭力轴系的力传递特性、均载特性,并对含弹性扭力轴系的分扭传动系统进行模态分析。研究结果表明,柔性轴主要承受转矩,轴上的弯矩非常小;与普通双联轴相比,弹性扭力轴系的均载特性更好;系统的运行工况在共振区之外,此分析结果对该系统的工程设计和动态分析具有一定的理论指导意义。

According to the design pattern,two analysis models of elastic torsion shafting and split torque transmission system with elastic torsion shafting are established with Romax.A study on characteristic of force transmission and load sharing of elastic torsion shafting is carried out.The modal analysis is also carried out for split torque transmission system with elastic torsion shafting.The study results show that the main flexible shaft is subjected to torque but not influenced by bending moment.The elastic torsion shafting has better characteristic of load sharing than common duplicate gear shaft.The running condition of system with elastic torsion shafting is out of resonance region.The study results are a theoretical guide for engineering design and dynamic analysis of this split-torque transmission system.
