The invention provides a bearing diagnosis device, a bearing diagnosis method and an escalator, which can grasp the state of a bearing device and take appropriate measures when a bearing is abnormal.The bearing diagnosis device is provided with a rotation cycle detection unit for detecting the rotation cycles of a rolling element, a retainer, and an annular member, and a storage unit for storingthe rotation cycles for comparison of the rolling element, the retainer, and the annular member. The rotation cycle detection unit compares the rotation cycle detected by the rotation cycle detectionunit with the rotation cycle data for comparison stored in the storage unit to diagnose the state of the bearing.
本发明提供能够掌握轴承的器件的状态,且在轴承发生异常的情况下采取合适的措施的轴承诊断装置、轴承诊断方法以及自动扶梯。轴承诊断装置具备检测滚动体、保持器以及环状部件各自的旋转周期的旋转周期检测部和存储滚动体、保持器以及环状部件的比较用旋转周期的存储部,对由旋转周期检测部检测出的旋转周期和存储于存储部的比较用旋转周期数据进行比较,诊断轴承的状态。
