Abstract
Device for locking a male element such as a shaft engaging in the bore of a female element such as a wheel hub against axial displacement. An annular groove is provided in the bore of the female member and has a first annular surface engageable by an elastically deformable locking ring mounted on a reduced section of the shaft member. A displaceable member such as a nut is moveable relative to the shaft member and has a second surface engageable with the locking ring. At least one of the surfaces is tapered so that upon movement of the surfaces toward one another, the locking ring is displaced radially outwardly to engage in the groove and lock the elements together.
Claims7
A device for locking male and female elements (1,2) against axial displacement relative to one another, said male element engageable in a bore of said female element and having a first section and a second section (8) of reduced cross-section connected by a first annular surface (5), means defining an annular groove (4) in the bore of said female element, an elastically deformable locking ring (6) mounted on the second section, a displaceable member moveable relative to the first section of said male element having a second surface (9) confronting said first surface and engageable with said locking ring, at least one of the first and second surfaces being tapered, said surfaces upon movement toward one another affecting radial outward displacement of said locking ring to engage in said annular groove, the annular space between the bore of said female element and the reduced second section of said male element being of greater cross-section than the cross-section of said locking ring so that the O-ring and male element may be moved in either direction in the bore of said female element when the O-ring is seated on said second section.
