圆振动筛激振器偏心振动的原因及解决办法

发布日期:2020-10-29 作者: 点击:

在制砂生产线,圆振动筛因为处理量大,产量高,因此选用激振器作为动力源,振动筛激振器采用轴承稀油润滑、外置式块偏心结构。具有激振力大,轴承负荷小、温度低,噪音小等特点。激振器整体拆装,维护、更换方便,大大缩短了检修周期。

振动筛激振器的轴承振动频率和设备筛箱弹性振动的某一阶段固有频率相同时,就会引起振动筛的筛箱弹性体的强烈振动。轴承主动轴与从动轴系统均存在某一数值的共振频率,如果有一些激振频率与共振频率接近,则发生共振。另外,由于偏心存在离心惯性力时,因此会产生弯曲振动,假如当转速接近临界值,则发生弯曲共振。
