How is propulsion turbine bearing wear determined?

Determining propulsion turbine bearing wear involves assessing the oil clearances and comparing the readings to established specifications. As bearing surfaces wear down over time, the oil clearance increases, which can lead to inefficient operation and possible equipment failure. Regular measurement of the oil clearance allows for the detection of wear patterns and helps ensure that the bearing operates within safe limits. Monitoring these measurements is critical in maintaining proper function and reliability of the turbine system, making this method a key indicator of bearing health.

In contrast, simply comparing rotor journal and bearing diameters does not provide the comprehensive information needed about wear since it doesn’t account for the clearance changes that occur during operation. Examining the turbine casing for damage might indicate external problems but does not give a direct insight into bearing wear. Inspecting the rotor for uneven wear also fails to directly measure the conditions of the bearings themselves, which are what impacts the turbine's performance and longevity the most.
