Abstract:

In the rail road industry damaged bearings in service are primarily identified by using wayside hot-box detectors (HBDs). In general if the temperature is greater than 105.5oC the wayside hot-box detectors (HBDs) would trigger the alarm. The present work aims at enhancing the Hot Box Detector temperature of Taper Roller Bearing which is subjected to lot of cyclic loads and suggested to increase the temperature to 120oC instead of 105oC as designed earlier. Finite Element Analysis is carried out to find out the temperature distribution between the cup and roller surface of the taper roller bearing and also stresses at different temperatures are determined to know the safe limit of the taper roller bearing in order to amplify the Hot Box Detectors (HBD) temperature. Fatigue life is also estimated at the corresponding loading conditions.
