Shackle for fastening an aircraft engine comprising a pair of encapsulated anti-friction coatings, and aircraft comprising such a shackle

A shackle for fastening an engine of an aircraft to a pylon secured to a structure of the aircraft, via at least one pin, the shackle comprising:

• a body, and
• a point for fastening to said pin via a ball joint, the ball joint comprising a ring having a spherical outer region and a first bore, the ring being assembled in a cavity of the body of the shackle having a shape complementary to said spherical outer region,
• the ball joint comprises a sleeve assembled in the first bore and having a second bore configured to receive said pin and a diameter of the sleeve progressively increases to have a flared inner surface at each of its ends, and
• at least one of
• a spherical outer surface of the ring bears a first anti-friction coating produced on a first region extending beyond its contact region with the body of the shackle and said first region of the ring is bordered by first rims forming a projection with respect to the spherical outer surface of the ring, around the first coating, so as to form a stop for protecting the first coating and to encapsulate the first coating, or
• the second bore of the sleeve bears a second anti-friction coating on a second region extending beyond its contact region with said pin and said second region is bordered by second rims forming a projection with respect to a surface of the second bore, around the second coating, at the ends of the flared inner surface of the second bore of the sleeve, so as to form a stop for protecting the second coating and to encapsulate the second coating.
