摘　　要：针对涡旋压缩机环销防自转机构的动力特性问题,在建立环销机构模型的基础上,得到含间隙的环销机构运动与力学分析模型。通过建立的模型,对环销间隙和间隙误差引起的环销性能变化进行研究。结果表明:均匀间隙主要影响环销接触力与环销作用区间;间隙误差会造成自转角存在较大波动,且环销接触力分配不均。Aiming at the dynamic characteristics of the ring pin anti-rotation mechanism of scroll compressor,based on the establishment of the ring pin mechanism model,the motion and mechanics analysis model of the ring pin mechanism with clearance is obtained.The change of ring pin performance caused by ring pin gap and gap error is studied by the model established.The results show that the uniform clearance mainly affects the contact force of the ring pin and the operating range of the ring pin.The gap error will cause large fluctuation of rotation Angle and uneven distribution of ring pin contact force.
