Title:
RESONANCE FREQUENCY MEASURING METHOD OF BEARING DEVICE
Document Type and Number:
Japanese Patent JP2009008615
Kind Code:
A
Abstract:
To provide a resonance frequency measuring method of a bearing device allowing a dummy mass to be fixed on the bearing device by using an adhesive in the same way as an actual use condition and removed from the bearing device after measurement easily.
In this resonance frequency measuring method, the dummy mass 23 for reducing resonance frequency of the bearing device 4 is fixed on the bearing device 4 by using the electrically-debonding adhesive being the adhesive to be released when voltage is applied; then resonance frequency is measured, and then voltage is applied on the electrically-debonding adhesive to release it from the bearing device 4 and remove the dummy mass 23 from the bearing device 4.
