DEVICE FOR ESTIMATING SERVICE LIFE AND METHOD FOR ESTIMATING SERVICE LIFE OF ROLLING BEARING |
摘要 |
The lifetime estimation device for a rolling bearing includes a buildup height estimation unit operable for estimating the buildup height of the indentation from a rolling surface from the depth of an indentation or the indentation size in accordance with a predetermined rule; and a lifetime estimation unit for estimating the service life of the rolling bearing in accordance with a rule stipulated according to the relationship between the estimated buildup height of the indentation and the rate of reduction of the rolling fatigue life and a dynamic equivalent load. The lifetime estimation unit calculates the service life of the rolling bearing corresponding to the contact surface pressure. |
