The invention relates to a rotor dynamic vibration absorber for inhibiting axial vibration, which comprises a vibration absorber body, a fixing frame and a guide assembly, the vibration absorber body is connected with the fixing frame through the guide assembly, the guide assembly is parallel to a transmission shaft to be subjected to vibration inhibition, and the vibration absorber body moves along the guide assembly to realize the inhibition of the axial vibration; the fixing frame comprises a left supporting plate and a right supporting plate which are symmetrically arranged, and the transmission shaft is installed on the supporting plates through double-row tapered roller bearings. The vibration absorber body comprises a mass unit, a linear bearing, a spring unit and a magnetic damping unit, wherein the spring unit and the magnetic damping unit are arranged between the mass unit and the supporting plate. According to the invention, vibration and impact vibration in the frequency band range of +/-15%-+/-20% of the resonance frequency of the rotor system can be well suppressed.

    本发明涉及一种抑制轴向振动的转子动力吸振器,包括吸振器本体、固定架、导向组件,吸振器本体通过导向组件与固定架连接,导向组件与要抑制振动的传动轴平行布置,吸振器本体沿导向组件移动实现抑制轴向振动;所述固定架包括左右两个对称布置的支承板,传动轴通过双列圆锥滚子轴承安装在支承板上;吸振器本体包括质量单元、直线轴承及设置在质量单元与支承板间的弹簧单元、磁性阻尼单元。本发明对转子系统共振频率±15%~±20%的频带范围内振动及冲击振动具有较好地抑制性能。
