Sliding mount
A mount according to an example of the present disclosure includes a locating pin, a load pin, a fastener, the fastener configured to retain a component on at least one of the locating pin and the load pin, the fastener including a bolt, a mounting boss and a spring, the spring allowing the mounting boss to move with respect to the bolt, and wherein the bolt is held captive in the mounting boss with a captive feature. A gas turbine engine and a method of mounting a component are also disclosed.
1. A gas turbine engine, comprising:
an engine case; and
a component; and
a mount configured to attached the component to the engine case, the mount including a locating pin, a load pin, and a fastener, the fastener configured to retain the component on at least one of the locating pin and the load pin, and wherein the fastener includes a bolt, a mounting boss and a spring, the spring allowing the mounting boss to move with respect to the bolt, and wherein the bolt is held captive in the mounting boss with a captive feature, the captive feature including a resilient c-ring on the bolt and a neck on the mounting boss, the resilient c-ring configured to be compressed by the neck on the mounting boss when passing the mounting boss and spring radially outward against an inner diameter of the mounting boss after passing the mounting boss.
2. The gas turbine engine of claim 1 , wherein the component is an actuator.
3. The gas turbine engine of claim 2 , wherein the actuator includes a piston that generates a load, and at least one of the locating pin and the load pin are configured to carry the load.
4. The gas turbine engine of claim 1 , wherein the fastener is configured to carry vibrational loads from an engine in the engine case.
5. The gas turbine engine of claim 1 , further comprising a retention feature retaining the bolt in the engine case.
6. The gas turbine engine of claim 5 , wherein the retention feature includes a threaded portion on the bolt and a shoulder on the bolt.
7. The gas turbine engine of claim 6 , wherein the threaded portion threads into the engine case such that the shoulder abuts the engine case.
8. A mount, comprising:
a locating pin;
a load pin; and
a fastener, the fastener configured to retain a component on at least one of the locating pin and the load pin, the fastener including a bolt, a mounting boss, and a spring, the spring allowing the mounting boss to move with respect to the bolt, and wherein the bolt is held captive in the mounting boss with a captive feature, the captive feature including a resilient c-ring on the bolt and a neck on the mounting boss, the resilient c-ring configured to be compressed by the neck on the mounting boss when passing the mounting boss and spring radially outward against an inner diameter of the mounting boss after passing the mounting boss.
9. The mount of claim 8 , wherein the spring is one of a wave washer, a belleville washer, and a single-coil wave spring.
10. The mount of claim 8 , wherein the bolt includes a reduced diameter threaded portion extending beyond the mounting boss.
11. The mount of claim 10 , wherein the bolt includes a flange at a first axial end of the bolt and the reduced diameter threaded portion is at a second axial end of the bolt opposite from the first end.
12. The mount of claim 10 , wherein the reduced diameter threaded portion is configured to thread into an engine case to connect the component to the engine case.
13. The mount of claim 8 , wherein the spring is arranged between the flange and a first axial end of the mounting boss.
