Title: VENTED BEARING RETAINER FOR TURBOMACHINES
Abstract:
Vented bearing retainer and roller bearings for turbomachines, such as compressors and turbines. Axial openings in, or adjacent to, the inner circumferential surface of the bearing retainer member equalize pressure differentials on the roller bearings. Axial grooves in the inner circumferential surface can be provided. Damper members on the OD of the retainer member can minimize rigid vibration modes and accommodate thermal growth and misalignment.
