Abstract
Abstract A fastening means for securing an annular first machine element against axial displacement on an annular second machine element, said second machine element having a shoulder against which the first machine element abuts and an annular groove spaced from said shoulder comprising a first ring member circumscribing the second machine element and having one axial end face confronting and abutting an axial end face of said first machine element and being formed to define an annular pocket, a second one-piece ring made of a deformable material which is initially sleeve-shape and is adapted to engage in the annular pocket and be deformed in a radial direction as a result of axially applied pressure during assembly into the annular pocket in such a way that a portion thereof engages in the annular groove in the second machine element to secure the two in place.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A fastening means securing an annular first machine element against axial displacement on an annular second machine element, said second machine element having a shoulder against which the first machine element abuts and an annular groove spaced from said shoulder comprising a first ring member circumscribing the second machine element and having one axial end face confronting and abutting an axial end face of said first machine element and defines an annular pocket, a second one-piece ring made of a deformable material which is initially sleeve-shaped and engages in the annular pocket is deformed in a radial direction as a result of axially applied pressure during assembly into the annular pocket in such a way that a portion thereof engages in the annular groove in the second machine element and secures the two in place.
Claim 2
Dependent Claim
135 words
A fastening means securing an annular first machine element against axial displacement on an annular second machine element, said second machine element having a shoulder against which the first machine element abuts and an annular groove spaced from said shoulder comprising a first ring member circumscribing the second machine element and having one axial end face confronting and abutting an axial end face of said first machine element and defines an annular pocket, a second one-piece ring made of a deformable material which is initially sleeve-shaped and engages in the annular pocket is deformed in a radial direction as a result of axially applied pressure during assembly into the annular pocket in such a way that a portion thereof engages in the annular groove in the second machine element and secures the two in place.
Claim 3
Dependent Claim
54 words
Fastening means as claimed in claim 1, wherein said second ring (16) mounted on the outside surface (9) of the shaft or the like (10) is provided with an inner surface (15, 21) which deflects the material of the initially sleeve-shaped ring (16) inward into the annular groove (17) during axial pressing in place.
Claim 4
Dependent Claim
31 words
Fastening means as claimed in claim 2, wherein said second ring (14) mounted on the outside surface (9) of the shaft or the like (10) has a curve-shaped inner surface (15).
Claim 5
Dependent Claim
54 words
Fastening means as claimed in claim 2, wherein said second ring (16d) mounted on the outside surface (9) of the shaft or the like (10) is constructed with an angularly cross section and has a front face (21) at the end of the expanded axial bore (19) which deflects the deformable construction material inward.
