The invention discloses a damping device of an elevator traction machine. The damping device of the elevator traction machine comprises a traction machine body, a base, a bearing beam and vibration absorption devices; the traction machine body is fixedly assembled on the base; the base is fixedly arranged on the bearing beam; the left and right ends of the bearing beam are fixed to a building wall; the vibration absorption devices comprise upper elastic bodies, middle mass bodies and lower elastic bodies; at least one vibration absorption device is arranged between an upper supporting flat plate and a lower supporting flat plate of the bearing beam; the vertical elastic coefficient of the middle mass bodies is far greater than the vertical elastic coefficient k1 of the upper elastic bodiesand the vertical elastic coefficient k2 of the lower elastic bodies; the masses of the upper elastic bodies and the lower elastic bodies are far less than the mass m of the middle mass bodies; wherein fA is equal to fB, and fB is the characteristic vibration frequency of the vertical vibration force generated by the traction machine when the elevator runs. The damping device of the elevator traction machine is convenient to install and capable of effectively preventing vibration force of the traction machine in the vertical direction from being transmitted to the building wall.

    本发明公开了一种电梯曳引机减振装置,曳引机固定装配在底座上;底座固定设置在承重梁上;承重梁的左右两端固定于建筑墙体;吸振装置包括上部弹性体、中间质量体和下部弹性体;承重梁的上支撑平板同下支撑平板之间设置有至少一个吸振装置;中间质量体的竖向弹性系数远大于上部弹性体的竖向弹性系数k1及下部弹性体的竖向弹性系数k2;上部弹性体及下部弹性体的质量远小于中间质量体的质量m;f=f,f为电梯运行时曳引机产生上下方向振动力的特征振动频率。该电梯曳引机减振装置,便于安装而且能有效抑制曳引机上下方向振动力传导到建筑墙体。
