针对影响涡旋压缩机振动及动力平衡问题 ,从四杆机构摆动力和摆动力矩及轴的惯性力矩平衡的原理出发 ,得出了这种方法与涡旋压缩机一次、二次平衡的方法在原理上基本一致的结论 ,即它们都以减轻惯性力作用在曲轴支承轴承的动载荷为目的 ,同时还比较了这两种方法的不同 ,提出了一些新的平衡方案 ,为较准确地平衡涡旋压缩机的惯性力和惯性力矩的影响奠定了基础 Aiming at the problems that affect the vibration and dynamic balance of scroll compressor, the principle of primary and secondary balance between this method and scroll compressor is derived from the principle of balance between swing force and swing moment of four-bar mechanism and moment of inertia of shaft The principle is basically the same conclusion, that is, they are to reduce the inertia force acting on the crankshaft bearing dynamic load for the purpose, but also compared the difference between the two methods, put forward some new balance scheme, in order to more accurately balance the vortex Rotary compressor inertia moment and the impact of inertia laid the foundation
