摘要/Abstract

摘要： 文章旨在深入探讨电动涡旋压缩机在运行中受到气体力的干扰所引发的轴承磨损问题，详细阐述了气体力对传动系统平衡状态的干扰，并剖析了振动对驱动轴承和整机性能所造成的负面影响。为了提高涡旋压缩机转子系统的精度和可靠性，利用三维建模软件 CATIA 和多体动力学分析软件 ADAMS 分别建立了转子系统的三维机构模型和多体动力学模型。通过特定转速下的仿真分析，重点研究了驱动轴承受力情况，并通过设计研究，对相关部件进行参数优化。研究结果显示，驱动轴承的受力呈现明显的大幅度周期性变化，特别是在 x 和 y 方向上的受力较大，造成系统的二次不平衡。通过优化减小了可驱动轴承的受力，从而减小了轴承的摩擦磨损，提高了其使用寿命，改善了涡旋压缩机运行的稳定性，降低系统的振动和噪声。

Abstract: The purpose of this paper is to delve deeply into the issue of bearing wear in electric vortex compressors caused by disturbances from gas forces during operation. It elaborates extensively on the interference of gas forces on the equilibrium state of the transmission system and analyzes the adverse effects of vibrations on the driving bearings and overall machine performance. To enhance the accuracy and reliability of the rotor system in the vortex compressor, threedimensional structural models and multi-body dynamics model of the rotor system are separately established using the 3D modeling software CATIA and the multi-body dynamics analysis software ADAMS. Through the simulation analysis of the specific speed, the stress of the drive bearing is studied, and the parameters of the related parts are optimized through the design research. The research results show that the force of the driving bearing presents a significant periodic change, especially in the x and y directions, resulting in secondary unbalance of the system. Through optimization, the force of the driving bearing is reduced, the friction and wear of the bearing are reduced, the service life is increased, the stability of the scroll compressor is improved, and the vibration and noise of the system are reduced.
