Abstract
An assembly for use with a gas turbine engine includes a block housing, a main bell crank, a bell crank, and a sync rod. The main bell crank extends between a main bell crank first end and a main bell crank second end that is connected to an actuator. The bell crank extends between a bell crank first end and a bell crank second end that is pivotally supported by the block housing. The sync rod is connected the main bell crank first end and the bell crank first end. The sync rod defines a first tab disposed proximate a first side and extends beyond a face of the sync rod.
Claims19
An assembly for use with a gas turbine engine, comprising:
- a block housing arranged to be disposed on a case of the gas turbine engine;
- a main bell crank pivotally supported by the block housing, the main bell crank extending between a main bell crank first end and a main bell crank second end that is connected to an actuator;
- a bell crank extending between a bell crank first end and a bell crank second end that is pivotally supported by the block housing;
- and
- a sync rod connected the main bell crank first end and the bell crank first end, the sync rod having a first side, a second side disposed opposite the first side, a first face and a second face disposed opposite the first face, each face extending between the first side and the second side, the sync rod defining a first tab disposed proximate the first side and extending beyond at least one of the first face and the second face.
A method of assembling a bell crank and bar assembly, comprising:
- pivotally connecting a bell crank having a bell crank first arm and a bell crank second arm to a block housing, an end surface of the bell crank second arm defines a perturbation;
- and
- disposing a sync rod between the bell crank first arm and the bell crank second arm, the sync rod having a first side, a second side, a first face and a second face disposed opposite the first face, each face extending between the first side and the second side, the sync rod defining a first tab that is disposed proximate the first side.
A gas turbine engine, comprising:
- a case disposed about a central longitudinal axis of the gas turbine engine;
- and
- a bell crank and bar assembly, comprising:
- a block housing arranged to be disposed on a case of the gas turbine engine,
- a main bell crank arranged to be pivotally supported by the block housing, the main bell crank having a main bell crank first arm and a main bell crank second arm spaced apart from the main bell crank first arm,
- a bell crank arranged to be pivotally supported by the block housing, the bell crank having a bell crank first arm and a bell crank second arm spaced apart from the bell crank first arm, and
- a sync rod arranged to be disposed between the main bell crank first arm and the main bell crank second arm and disposed between the bell crank first arm and the bell crank second arm, the sync rod defining a first tab arranged to engage an end surface of at least one of the main bell crank second arm and the bell crank first arm.
