Bearing loading conditions: shaft - bearing - housing approach
Download as PPTX, PDF0 likes2,666 views
This document discusses methods for evaluating bearing loading conditions in rotating equipment. The shaft-bearing-housing method allows for quick selection of bearing candidates by considering shaft and housing geometry as well as detailed internal bearing geometry. It is applicable to any number of supports and covers most situations, including evaluation of preload for grouped axial bearings. However, it requires calculation software and knowledge of bearing internal geometry, and models the shaft and housing with beam elements that do not account for ovalization.
Bearing loading conditions: shaft - bearing - housing approach
- 1. Evaluation of bearing loading conditions in rotating equipment Method Pros Cons Shaft-bearing-housing ? Relatively quick selection of bearing candidates ? Shaft and housing geometry ? Detailed internal bearing geometry ? Applicable for any number of supports ? Cover the majority of the situations ? Evaluate the preload/clearance of grouped axial bearings ? Calculation software needed ? Bearing internal geometry needed ? Shaft and housing mostly modelled with beam finite elements (no ovalization) A. Bacchetto
