Abstract

The technology disclosed in the present specification is embodied as a support device for supporting maintenance on an apparatus including an expendable component. The support device includes at least one computer. The at least one computer executes: a process of acquiring an index indicative of a consumption level of the expendable component; a process of, at a time point when the index indicative the consumption level reaches a predetermined threshold, specifying a necessary period of time required for replacement of the expendable component at the time point; and a process of restricting an operation of the apparatus when a remaining period of time of the expendable component, the remaining period of time being associated with the threshold, is shorter than the necessary period of time required for the replacement.

First claim

What is claimed is:

1. A support device for supporting maintenance on an apparatus including an expendable component, the support device comprising at least one computer configured to:
acquire an index indicative of a consumption level of the expendable component;
specify a necessary period required for replacement of the expendable component at a first time point when the index indicative of the consumption level reaches a threshold;
specify the necessary period at a second time point before the index indicative of the consumption level reaches the threshold; and
restrict an operation of the apparatus and correct the threshold when a remaining period of the expendable component is shorter than the necessary period required for the replacement, the remaining period being associated with the threshold.

2. The support device according to claim 1 , wherein the at least one computer is configured to restrict the operation of the apparatus more greatly as the remaining period of the expendable component becomesis shorter and shorter than the necessary period required for the replacement.

3. The support device according to claim 1 , wherein the at least one computer is configured to correct, the threshold more greatly as the remaining period of the expendable component becomes shorter and shorter than the necessary period required for the replacement.

4. The support device according to claim 1 , wherein the at least one computer is configured to communicate with an external device configured to manage the necessary period required for the replacement of the expendable component.

5. The support device according to claim 1 , wherein the index indicative of the consumption level is strength of an order component corresponding to the expendable component, the order component being extracted from vibration data measured by the apparatus.

6. The support device according to claim 5 , wherein:
the expendable component is a gear or a bearing; and
the order component corresponding to the expendable component is correlated with a corresponding one of the number of teeth of the gear or the number of rolling elements of the bearing.

7. The support device according to claim 5 , wherein:
the apparatus includes a plurality of the expendable components.

8. The support device according to claim 1 , wherein the apparatus is a hydraulic power generating system.

9. A support device for supporting maintenance on an apparatus including an expendable component, the support device comprising at least one computer configured to:
acquire an index indicative of a consumption level of the expendable component;
determine whether or not the index indicative of the consumption level reaches a threshold;
specify a necessary period required for replacement of the expendable component at a time point before the index indicative of the consumption level reaches the threshold; and
correct the threshold when a remaining period of the expendable component is shorter than the necessary period required for the replacement, the remaining period being associated with the threshold.
