摘要(Abstract)：

为了研究无油涡旋压缩机传动系统的动力特性问题,对涡旋压缩机的传动系统模型进行了简单的分析,利用Solidworks建立了涡旋压缩机的三维模型,并根据其运动规律,将其嵌入Adams虚拟样机软件中,建立了涡旋压缩机传动系统的动力学模型,针对曲柄销和小曲拐与轴承之间运动副间隙的大小,进行了传动系统的动力学仿真,结果表明:曲柄销和小曲拐与轴承之间运动副间隙的大小对于涡旋压缩机传动系统的动力特性有着显著的影响。合理控制轴承装配间隙有利于提高涡旋压缩机的动力特性以延长其使用寿命。
In order to study the dynamic characteristics of the transmission system of an oil-free scroll compressor,a simple analysis of the transmission system model of the scroll compressor was performed. The three-dimensional model of the scroll compressor was established using Solidworks,and was embedded in the Adams virtual prototype software according to its movement law.A dynamic model of the transmission system of the scroll compressor was established. For the size of the movement clearance between the crank pin and the small crank bearing,the dynamic simulation of the transmission system was performed. The results show that the size of the movement clearance between the crank pin and the small crank bearing has a significant influence on the dynamic characteristics of the transmission system of the scroll compressor. Reasonable control of the bearing assembly clearance is beneficial to improving the dynamic characteristics of the scroll compressor and prolonging its service life.
