Abstract
A locking pin is disposed in an oblique bore in a lock nut for engagement of the inner end of the pin against a threaded portion on which the nut is to be mounted, the inner end of the locking pin displaying a shape which fits the thread of the threaded portion. The common longitudinal axis of the bore and the locking pin extends at substantially the same angle as one nut thread flank, and the inner end of the locking pin has at least one thread flank which is substantially parallel to the longitudinal axis.
Claims5
A lock nut for attachment to an exteriorly threaded member, said lock nut comprising:
- a nut having a threaded axial opening adapted to be threaded onto an exteriorly threaded member;
- said nut having therein an oblique bore extending from said axial opening;
- a locking pin positioned in said oblique bore, said locking pin having an inner end which is shaped to fit within the threads of the exteriorly threaded member;
- said oblique bore and said locking pin having a common longitudinal axis extending at substantially the same angle to the longitudinal axis of said axial opening as does one of the thread flanks of the threads of said axial opening of said nut;
- said inner end of said locking pin having at least one thread flank extending substantially parallel to said common longitudinal axis;
- and
- said common longitudinal axis extending at an angle to a plane which is transverse to said longitudinal axis of said axial opening, and said common longitudinal axis lying on a plane which extends along said longitudinal axis of said axial opening.
