本发明提供一种旋转体以及应用了该旋转体的电梯,能够防止轴承所使用的润滑剂泄漏。具备:主轴,其成为旋转轴;第一结构体,其经由轴承以能够旋转的方式支撑于主轴;以及第二结构体,其经由液状垫圈安装于第一结构体,对设置有轴承的空间进行密封。另外,还具备:螺栓孔,其从第二结构体设置到第一结构体侧;固定螺栓,其与所述螺栓孔螺纹结合,用于将第二结构体固定于第一结构体;以及通气孔,其设置于第一结构体,与螺栓孔连通,并且连通于与设置有轴承的空间不同的空间。

    To provide a rotor capable of preventing leakage of a lubricant used for a bearing and an elevator to which the rotor is applied.SOLUTION: The rotor comprises: a main spindle which serves as a rotary shaft; a first structure rotatably supported on the main spindle via a bearing; and a second structure that is attached to the first structure via a liquid gasket and that seals a space provided with the bearing. The rotor further comprises a bolt hole provided from the second structure to the first structure side, a fixing bolt engaged with the bolt hole to fix the second structure to the first structure, and a ventilation hole provided in the first structure, communicated with the bolt hole, and communicated with a space different from the space provided with the bearing.SELECTED DRAWING: Figure 2
