The need to understand and quantify the heat transfer paths within tapered-roller bearings is
of great importance in the railroad industry since bearing cup temperature measurement is …

In the railroad industry, distressed bearings in service are primarily identified using wayside
hot-box detectors (HBDs). Current technology has expanded the role of these detectors to …

The rolling surface for railroad wheels can be a heat source that may have an impact on the
performance of the wheel bearing. In this study, experimental data from an electrically …

Exact solutions are given for the transient temperature in flux-base fins with the method of
Green's functions (GF) in the form of infinite series for three different tip conditions. The …

At present there are no existing bearing health monitoring systems capable of continuous
monitoring and tracking of railroad bearings on freight cars. Current wayside equipment is …

Bearing temperature trending is an ongoing problem that is receiving considerable attention
in the railroad industry. Currently, bearings that display this phenomenon are removed from …

Over the last three years, numerous laboratory tests have been conducted with the goal of
identifying the root cause of the temperature trending phenomenon observed in tapered …

In the railroad industry, bearing hot-box detectors are the primary tools utilized for the
removal of distressed bearings from service. Current technology has expanded the role of …

Catastrophic bearing failure is a major concern for the railroad industry because it can lead
to costly train stoppages and even derailments. Excessive heat buildup within the bearing is …

In the rail road industry damaged bearings in service are primarily identified by using
