Document Type and Number:
Japanese Patent JP2013170988
Kind Code:
A
Abstract:

To provide a rolling bearing state display device capable of further accurately showing a rolling state which is wanted to be inspected, even if there are a plurality of rolling bearings.

A rolling bearing state display device includes: a vibration detecting device 50 making at least one of a plurality of rolling elements 23 heavy and hard, and detecting the vibration frequency and the vibration strength of a rolling bearing; an angle detecting device 55 for detecting an angle of a holder 24; a first storage device 63 for storing frequency, vibration strength, and an angle; area setting means for setting an area of vibration strength larger than the vibration strength of the plurality of rolling elements 23 except for the heavy and hard one; frequency selecting means for storing the vibration strength having the corresponding frequency and the angle from the first storage device 63 to a third storage device 63, when the vibration strength of an area set by the area setting means is detected; and a display device 66 for waveform-displaying the vibration of the rolling bearing on the basis of the frequency, the vibration strength, and the angle stored in the third storage device 63.
