Title:
軸受装置の予圧量の測定方法、および軸受装置の組立方法
Document Type and Number:
Japanese Patent JP5347391
Kind Code:
B2
Abstract:
To provide an assembling method of a bearing device, capable of improving the accuracy for management of preload quantity by suppressing the variation of natural frequency.
In a roll bearing device 1, a flange part 32 of a fixed body 3 is vibrated by an excitation part 9. The vibration given to the bearing device 1 is detected by a noncontact sensor of a vibration detection part 10, and a bending vibration mode of the fixed body 3 is detected by an arithmetic determination part 11. The preload quantity of the device 1 is estimated based on the natural frequency of the bending vibration mode of the fixed body 3 and a preset natural frequency of bending vibration mode of the fixed body 3.
