基于UG的复合轮系齿轮传动三维建模及运动仿真分析

摘要

以复合轮系齿轮传动为例，对传动机构进行原理分析，利用传动比计算公式计算出复合轮系中关键齿轮的旋转速度，得出UG运动仿真参数。利用UG中齿轮工具箱完成锥齿轮和直齿轮的建模与啮合装配，对旋转副和齿轮副进行运动仿真，通过运动仿真可直观地观察齿轮传动状态，然后进行图表分析，以验证轮系设计的合理性。%With the compound gear train gear as an example,the principle of driving mechanism is analyzed,the transmis-sion ratio calculation formula is used to calculate the rotational speed of key gears in the compound gear train,obtaining UG motion simulation parameters. The gear toolbox in UG is utilized to complete modeling and engage assembly of spur gears and bevel gears,with motion simulation of rotating vice and gear pair conducted,which can realize intuitive observation of gear transmission state and graph-based analysis to verify the rationality of gear train design.
