AI Technical Summary
Technical Problem
Existing hydrodynamic bearings face challenges in maintaining stability and reducing power losses under dynamic loads, particularly due to issues with pad separation, temperature regulation, and pivot wear.
Method used
A modular bearing design featuring replaceable, pivot-connected pad modules with an I-beam shaped web portion, integrated into a bearing housing with axial grooves and fasteners, which allows for tilting of pad bodies and inhibits radial separation.
Benefits of technology
This design enhances maintainability, reduces pivot wear and contact stresses, improves rotodynamic behavior, and decreases pad temperature and power loss, making larger bearings easier to produce and maintain.

Abstract
A hydrodynamic bearing for supporting a shaft includes a bearing housing and one or more pad modules. The bearing housing defines an inner surface and one or more axial grooves adjoining the inner surface. Each of at least one of the one or more pad modules includes a pad body, a root portion configured to couple in one of the axial grooves of the bearing housing, and a web portion connecting the pad body and the root portion.
