Abstract:
1. A fastener assembly comprising: a threaded bolt including a groove formed in threads of the bolt extending in a direction parallel to the rotational axis of the bolt; a nut including a threaded bore for threading the nut onto the bolt and a plurality of nut teeth formed on a face around the threaded bore and protruding from the face in a direction parallel to a rotational axis of the nut, at each cross section taken through each nut tooth normal to a radius emanating from the nut's rotational axis each intersection of a nut tooth trailing edge and the face being offset an equal distance from the radius in a direction perpendicular to the radius and each nut tooth trailing edge being disposed at a rake angle less than 0°; a locking ring including a locking ring bore, an inward extending tab received in the groove of the bolt and a plurality of locking ring teeth formed on a surface around the locking ring bore for engaging the nut teeth, the locking ring teeth protruding from the surface in a direction parallel to a rotational axis of the locking ring, at each cross section taken through the locking ring teeth normal to a radius emanating from the locking ring's rotational axis each intersection of a locking ring tooth trailing edge and the surface being offset an equal distance from the radius in a direction perpendicular to the radius and each locking ring tooth trailing edge being disposed at a rake angle less than 0°; and a biasing member biasing the nut towards the locking ring.
