Abstract
An air turbine starter includes a support structure and a turbine having a shaft and a rotor that extends away from the shaft in a radial direction. The air turbine starter also includes a mount structure that supports the turbine for rotation relative to the support structure. The mount structure is configured to transfer a force from the turbine to the support structure. The mount structure includes a deformable member that is configured to deform when the force exceeds a predetermined threshold.
Claims20
An air turbine starter comprising:
- a support structure;
- a turbine that includes a shaft and a rotor that extends away from the shaft in a radial direction;
- a mount structure that supports the turbine for rotation relative to the support structure, the mount structure configured to transfer a force from the turbine to the support structure, the mount structure including a deformable member that is configured to deform when the force exceeds a predetermined threshold.
A deformable member of a mount structure of an air turbine starter, the deformable member comprising:
- an inner member configured to abut an outer race of a bearing, the bearing configured to support rotation of a turbine of the air turbine starter;
- an outer member configured to fixedly attach to a support structure of the air turbine starter;
- a transverse support member that extends between the inner member and the outer member, the transverse support member configured to transfer a force from the inner member to the outer member;
- and
- a deformable portion configured to deform when the force exceeds a predetermined threshold.
