Patent number: 10208784Abstract: Systems and methods are disclosed herein for dressing centering a bearing compartment in a gas turbine engine. A nut may be inserted through an outer case of a gas turbine engine. The nut may be coupled to a strut which centers a bearing compartment. The nut may be rotated to achieve a desired tension on the strut to center the bearing compartment. A retaining plate comprising a collar may be positioned over the nut. A swaging tool comprising a swaging ramp may be positioned over the nut. The swaging tool may be forced against the retaining plate using a draw-in bolt. The swaging ramp may contact the collar and form indentations in the collar to lock the nut in place.Type: GrantFiled: July 19, 2017Date of Patent: February 19, 2019Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Steven J. Bauer, Christine F. McGinnis
