Abstract
A connector that receives a threaded apparatus and reduces stresses induced from the treaded apparatus into the connector is described. The connector includes a top side, a bottom side, and an opening that extends therethrough. The opening is defined by an inner surface that includes a threadform including a plurality of threads. The threads extend radially outward from the inner surface into the connector opening and include a first thread portion and a cutback that extends through a portion of the threadform. The cutback facilitates less stresses being induced into the first thread portion.
Claims4
A method for fabricating a connector for a gas turbine engine, the connector sized to receive a threaded apparatus, the connector including a first side, a second side, and an opening extending therebetween and defined by an inner surface, said method comprising the steps of:
- forming threads into the connector inner surface, such that the threads are axially-spaced substantially constant along the connector inner surface and wherein a first thread is the first of said threads which initially engages the threaded apparatus that is rotated within the connector opening and coupled to said connector;
- and
- forming a cutback to extend into the connector inner surface to reduce stresses induced into the plurality of threads by the threaded apparatus wherein the cutback extends through the first thread.
