Alignment Analysis
The first step in successful alignment of ship propulsion shafting is to determine what the alignment should be to satisfy all operating conditions over the stern bearing weardown range.
Diehl Engineering Company will perform an analysis of the shafting system to determine proper bearing offsets to achieve optimum bearing loading while minimizing shaft bending stresses. Our analysis utilizes our own proprietary computer modeling program, and considers such factors as bearing clearances, bearing weardown, thermal changes, reduction gear alignment to minimize gear skew, and whirling vibration.
DEC will integrate the results of alignment measurement via optical sighting, strain gages, and/or load cell, to determine existing alignment, provide recommendations for what to do to improve alignment, and measure the final results.
