Title:
PRE-LOAD MEASURING METHOD OF MULTIPLE LINE ROLLING BEARING
Document Type and Number:
Japanese Patent JP3174759
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of accurately and simply measuring a pre-load applied to a rolling bearing in which rolling elements are installed in a multiple line.
SOLUTION: A first pre-load gap of a rolling element 4e of one line and a track corresponding to the rolling element 4e, and a second pre-load gap of a rolling element 4i of the other line and a track corresponding to the rolling element 4i are independently measured and the ratio is previously obtained. About a bearing to be measured, only one out of the first pre-load gap and the second pre-load gap is measured. On the basis of the measured value and the ratio, the other pre-load gap is obtained. Both of the pre-load gaps are summed and a pre-load gap of the whole bearing is obtained. The pre-load gap is elastic deformation formed in accordance with an applied pre-load, so that measuring the pre-load gap is equivalent to measuring the pre-load.
