带有惯性振动器的筛分机具有高噪音级,此噪音级是由在声频上有较高的振动效能决定的。单轴惯性振动器以及自同步双轴惯性振动器具有高振动效能的主要原因在于:轴承支点中的动力学过程。上述过程的强化程度在很大程度上取决于选择振动器的系统,包括零件和装配组件的尺寸、轴承型号和规格、润滑以及作用在每一个轴承上力的大小。我们来研究双轴振动器的不平衡轴,该轴带有两个轴承支点,每个轴承支点中安装一个轴承。轴承支点的振动效能在给定负荷条件下,不仅仅取决于轴承型式、轴承制造精度等 Screens with inertial vibrators have a high noise level, which is determined by the higher vibrational efficiency of the audible frequency. The main reason for the high vibration performance of single-axis inertial vibrators and self-synchronizing dual-axis inertial vibrators is the dynamic process in the bearing fulcrum. The degree of reinforcement of this process depends greatly on the system of choice for the vibrator, including the dimensions of the parts and assemblies, bearing type and size, lubrication, and the amount of force acting on each bearing. We study the unbalanced shaft of a biaxial vibrator with two bearing fulcrums and a bearing for each bearing fulcrum. Bearing fulcrum vibration performance under given load conditions, not only depends on the bearing type, bearing manufacturing precision
