Abstract
The support structure for the bearing compartment for a gas turbine engine includes eight radial tie bolts connected with the clevis wherein the outer diameter clevis is connected to the mount ring with an accessible bolt for easy assembly and disassembly. The tie bolts, while preloaded in tension, can accept compressive loads during severe loading operation conditions. The turbine exhaust case housing the tie bolts and bearing compartment are designed to facilitate cooling and maintainability at reduced costs.
Claims7
For a gas turbine engine having a turbine section including a bearing rotatably supported in a bearing housing, means for supporting said bearing housing including a turbine exhaust case having an outer ring and an inner ring in concentric and spaced relationship, a plurality of circumferentially spaced hollow struts interconnecting and supporting said inner ring and said outer ring to each other, an outer casing included a mount ring for said engine surrounding said outer ring, a plurality of rods interconnecting said bearing housing and said mount ring, each of said rods including a spherical bearing formed on one end, at least a first clevis hingedly supported at one end of said rod including a spherical ball supported between the U-shaped portion of said clevis, a bolt extending through an opening formed in said mount ring and aligned with a threaded opening formed in said clevis whereby tightening said bolt applies a tension to said rod.
