Bearing Pad Hollow Structure for Cooling Without Strength Loss

The bearing pad employs a porous sintered metal material that inherently contains interconnected pores. These pores serve as cooling channels for lubricating oil flow while the sintered structure maintains structural strength. The porous material allows oil to permeate and cool the pad interior without requiring separate flow paths that would compromise structural integrity.

The bearing pad utilizes a composite structure combining sintered metal material with embedded oil retention holes and flow paths. This composite approach integrates cooling functionality within the structural material itself, allowing simultaneous achievement of thermal management and mechanical strength through the synergistic combination of porous matrix and fluid channels.

The porous sintered metal structure is manufactured using powder metallurgy techniques where the porous network is formed directly during the sintering process. Oil retention holes are created as part of the green body formation or subsequent drilling, and flow paths develop through the porous structure naturally. This integrated manufacturing approach avoids complex post-processing required for solid materials with internal channels.

The porous structure itself provides the cooling flow paths without requiring additional manufactured channels. The natural pore network of the sintered material serves as the lubricating oil flow path, eliminating the need for separate hollow portions or complex channel fabrication. The material structure automatically provides the cooling functionality.
