Combined heat shield and retainer for turbine assembly bolt.

摘要

The present invention provides an annular integral bolt heat shield (26) and axial retention apparatus to axially retain bolts used for holding together two rotor elements during assembly when the bolts (22) are otherwise subject to sliding into a closed cavity (88) of the assembled engine or one of its modules. The integral retainer and heat shield engage the bolts disposed through bolt holes in a gas turbine engine rotor shaft so that the bolts remain straight during assembly when a second rotor element such as a second shaft is being attached to the first shaft, and bolt holes in the second shaft have to engage and fit over the bolts of the first shaft.
