Abstract
An axial impact liner comprises a bearing liner having a shear member and a pocket. A spring and a supply of oil may be included within the pocket. In the event of an axial load, such as from a bearing or main rotor failure, the axial impact liner can shear in the axial direction and absorb the energy of the axial load by forcing the shear member into the oil filled pocket and against the spring. The pocket comprises a volume capable of accommodating the full axial distance that the rotor could move.
Claims19
A system for an electrical machine comprising:
- a liner member having an inner diameter surface;
- a shear member extending radially inward from said inner diameter surface, said shear member shearing from said liner member when said shear member is exposed to an axial force from a main rotor shaft;
- and
- a pocket at least partially defined by said liner member and said shear member.
A system for an electrical machine comprising:
- a cylindrical structure;
- a shear member extending from an inner diameter surface of said cylindrical structure and towards a main rotor shaft of said electrical machine, said shear member shearing from said cylindrical structure when said shear member is exposed to an axial force from a main rotor shaft;
- a pocket adjacent to said shear member;
- a supply of pressurized oil positioned within said pocket, the pressurized oil contained within said pocket to absorb an axial force from a main rotor shaft of said electrical machine;
- and
- a spring positioned within said pocket.
A system for a bearing support assembly comprising:
- a cylindrical portion;
- an end portion integral to and positioned at one end of said cylindrical portion;
- a shear member extending radially inward from said cylindrical portion, said shear member shearing from said cylindrical portion when said shear member is exposed to an axial force from a main rotor shaft;
- a pocket defined at least in part by said cylindrical portion, said end portion and said shear member;
- and
- a supply of pressurized oil disposed in said pocket the pressurized oil contained within said pocket to absorb an axial force from a main rotor shaft of said electrical machine.
