Abstract
A pin assembly according to an exemplary embodiment of this disclosure, among other possible things includes a spring housing, a spring situated in the spring housing, a pin having a first end configured to be received in the spring housing and to engage the spring, and a boot configured to receive a second end of the pin. The boot is configured to span a gap between first and second adjacent components and configured to transfer a spring force from the spring to the first and second adjacent components. A vane assembly and a method of assembling a vane assembly are also disclosed.
Claims17
A pin assembly, comprising:
- a spring housing;
- a spring situated in the spring housing;
- a pin having a first end configured to be received in the spring housing and to engage the spring;
- a boot configured to receive a second end of the pin, wherein the boot is configured to span a gap between first and second adjacent components and configured to transfer a spring force from the spring to the first and second adjacent components;
- and
- a seal, the seal having an opening configured to receive the second end of the pin.
An airfoil assembly for a gas turbine engine, comprising:
- first and second vanes arranged adjacent to one another with a gap therebetween;
- an annular support structure arranged radially outward from the vanes;
- a spring housing fixed to the annular support structure;
- a spring situated in the spring housing;
- a pin having a first end configured to be received in the spring housing and to engage the spring;
- a boot spanning the gap, the boot configured to receive a second end of the pin and configured to transfer a spring force from the spring to the first and second vanes;
- and
- a seal, the seal having an opening configured to receive the second end of the pin.
A method of assembling a vane assembly, comprising:
- situating a boot across a gap between adjacent first and second vanes;
- inserting a pin through a spring housing such that a first end of the pin is received in the boot;
- inserting a spring into the spring housing such that the spring engages a second end of the pin;
- compressing the spring such that the spring force is transferred to the first and second vanes and
- inserting the boot into an opening of a seal, and situating the boot and seal across the gap prior to inserting the pin.
