Abstract
An aircraft spherical bearing assembly comprises a first part which is in sliding contact with an intermediate part for sliding therebetween to form a spherical joint. A second slip path is provided between the intermediate component and an outer component which can be selectively actuated when the force through the first slip path exceeds a predetermined level.
Claims11
An aircraft spherical bearing assembly comprising:
- a first part, a second part and an intermediate part, in which the first part is coupled to the intermediate part to form a first spherical joint about a tint centre point, and the intermediate part is coupled to the second part to form a second spherical joint about a second centre point, the first and second centre points being substantially coincident;
- the aircraft spherical bearing assembly comprising a separate load sensing element positioned between the intermediate part and the second part to provide a primary load path therebetween,
- wherein below a predetermined torque the separate load sensing element is in a first position to provide a positive connection between the intermediate part and the second part to prevent rotation of the second part relative to the intermediate part;
- and,
- wherein above the predetermined torque the separate load sensing element moves to a second position to permit rotation of the second part relative to the intermediate part.
