Abstract

A mount assembly for attaching a heat exchanger to a casing of a gas turbine engine comprises a support bracket and a pin body, the pin body laterally moveable in use relative to the support bracket. The assembly further comprises a spring that in use can apply a restoring force to the pin body opposed to its lateral movement relative to the support bracket.

First claim

The invention claimed is:

1. A mount assembly comprising:
a casing of a gas turbine engine;
a support bracket mounted to the casing;
a pin body, the pin body laterally moveable in use relative to the support bracket;
a spring that in use can apply a restoring force to the pin body opposed to its lateral movement relative to the support bracket; and
an anti-rotation device, the anti-rotation device comprising a plate including a slot, sides of the slot engaging a polygonal hub formed on the pin body.

2. The mount assembly of claim 1 , in which the assembly comprises two springs.

3. The mount assembly of claim 2 , in which the two springs act in use to center the pin body on the support bracket.

4. The mount assembly of claim 1 , in which at least one washer is interposed between the pin body and the support bracket to ensure their correct location.

5. The mount assembly of claim 1 , wherein:
the mount assembly is configured to attach a heat exchanger to the casing of the gas turbine engine;
the support bracket includes a hole, the hole having a hole axis; and
the pin body is laterally moveable in use relative to the support bracket, in a direction perpendicular to the hole axis; the mount assembly further comprising:
a bolt that passes through the hole of the support bracket and is connected to the pin body, the bolt being laterally moveable in the hole, in a direction perpendicular to a longitudinal axis of the bolt, in accordance with lateral movement of the pin body, the longitudinal axis of the bolt being parallel to the hole axis.

6. The mount assembly of claim 1 , wherein:
the mount assembly is configured to attach a heat exchanger to the casing of the gas turbine engine;
the support bracket includes a hole, the hole having a hole axis perpendicular to a main surface of the support bracket;
the pin body is laterally moveable in use relative to the support bracket, in a direction perpendicular to the hole axis; and
the spring in use can apply the restoring force in the direction perpendicular to the hole axis.

7. A mount assembly configured to attach a heat exchanger to a casing of a gas turbine engine, the assembly comprising:
a support bracket for mounting on the casing of the gas turbine engine, the support bracket including a hole, the hole having a hole axis;
a pin body, the pin body being laterally moveable in use relative to the support bracket, in a direction perpendicular to the hole axis;
a bolt that passes through the hole of the support bracket and is connected to the pin body, the bolt being laterally moveable in the hole, in a direction perpendicular to a longitudinal axis of the bolt, in accordance with lateral movement of the pin body, the longitudinal axis of the bolt being parallel to the hole axis;
a spring that in use can apply a restoring force to the pin body opposed to its lateral movement relative to the support bracket; and
an anti-rotation device, the anti-rotation device comprising a plate including a slot, sides of the slot engaging a polygonal hub formed on the pin body.

8. A mount assembly configured to attach a heat exchanger to a casing of a gas turbine engine, the assembly comprising:
a support bracket for mounting on the casing of the gas turbine engine, the support bracket including a hole, the hole having a hole axis perpendicular to a main surface of the support bracket;
a pin body, the pin body laterally moveable in use relative to the support bracket, in a direction perpendicular to the hole axis;
a spring that in use can apply a restoring force, in the direction perpendicular to the hole axis, to the pin body opposed to its lateral movement relative to the support bracket; and
an anti-rotation device, the anti-rotation device comprising a plate including a slot, sides of the slot engaging a polygonal hub formed on the pin body.
