BEARING SUPPORT STRUCTURE

摘要

Bearing Support Structure The intermediate case for turbo fan engines has a bearing support cone extending forwardly from the support flange in alignment with the struts in the case to provide a secure support for the #2 bearing for the low pressure shaft. To accommodate the power shaft assembly which extends through the cone the latter has a bulge in which is mounted the support cylinder for the bearings for the power shaft, this bulge providing a support structure for the cylinder and clearance for a bevel gear on the power shaft journaled in the cylinder.
