Abstract
A device (1) for calibrating a spall propagation model (12a) of a bearing (3) includes a processing means (8) for determining a condition indicator from measurements of the bearing (3). A determining means (9) determines a first calibrating value (CV1) representative of the appearance of a spall in a stationary ring (4) or rotating ring (5) of the bearing (3) after N1 number of revolutions of the bearing and a second calibrating value (CV2) representative of the evolution of the spall in the stationary ring (4) or rotating ring (5) after N2 number of revolutions of the bearing from the condition indicator. N2 is greater than N1. Identifying means (10) identifies at least one stage of propagation of the spall from the two calibrating values (CV1, CV2). A calibrating means (11) calibrates the spall propagation model (12a) from the two calibrating values (CV1, CV2).
