WIPO Patent Application WO/2018/050008
Kind Code:
A1
Abstract:
A monitoring method and monitoring apparatus for the remaining life of a bearing. The monitoring method comprises: during the operation of a bearing, determining the position where a defect of the bearing is located, and determining the size of the defect (S10); according to the position where the defect is located and a set condition, determining a failure mode of the bearing, and an expansion rate and a failure value of the defect in the failure mode (S20), the failure value being the maximum value that the defect can reach when the bearing fails; and based on the size, expansion rate and failure value of the defect, obtaining the remaining life of the bearing (S30). The monitoring method and monitoring apparatus can determine the remaining service life of a bearing, so that maintenance personnel arrange a maintenance plan and counter measures in advance.
