针对无油涡旋空压机转子系统高速运动时的不平衡问题可能引发主轴震颤或主机强烈振动,造成设备损坏等问题,优化设计一种涡旋空压机转子系统动平衡结构。首先,通过理论方法进行不平衡量分析和平衡块初步设计;然后通过三维模型软件完成模块的虚拟装配和干涉检查;最后通过动力学仿真软件ADAMS和试验方法验证设计的可行性。研究结果表明:本文的设计可明显减少旋转主轴上的惯性力和惯性矩,改善主轴转子系统的工作性能。

Aiming at the problem of imbalance in the high-speed motion of the rotor system of oil-free vortex air compressor,which may cause spindle vibration or strong vibration of the main engine,resulting in equipment damage,an optimized design of a dynamic balance structure for the vortex air compressor rotor system is proposed.Firstly,an imbalance analysis and a preliminary design of balance blocks are conducted through theoretical method.Then the virtual assembly and interference inspection of the module are completed through 3D modeling software.Finally,the feasibility of the design was verified through dynamic simulation software ADAMS and experimental methods.The research results indicate that the design in this paper can significantly reduce the inertial force and moment of inertia on the rotating spindle,which could improve the working performance of the spindle transmission system.
