Abstract

A securing ring, includes a body defining a ring opening and having a circumference of substantially circular configuration at formation of a slotted gap to define confronting ring ends. The body defines a ring plane and an axis of symmetry and has a radial width which continuously increases, at least in sections, from the ring ends onwards at both sides of the axis of symmetry. Each of the ring ends has a L-shaped configuration and is extended by a lug jutting out from the ring plane and formed with a throughbore. Both lugs of the ring ends are positioned on a same side of the ring plane, with the throughbores of the lugs extending in parallel relationship to one another and to the ring plane.

Claims

1. A securing ring, comprising a body made of spring steel and defining a ring opening, said body having a circumference of substantially circular configuration at formation of a slotted gap to define confronting ring ends, said body defining a ring plane and an axis of symmetry and having a radial width which widens, at least along predetermined regions, from the ring ends onwards at both sides of the axis of symmetry, each of said ring ends exhibiting a L-shaped configuration and being extended by a lug jutting out from the ring plane and formed with a throughbore, said lug of one of the ring ends and said lug of the other one of the ring ends being positioned on a same side of the ring plane, with the throughbores of the lugs extending in parallel relationship to one another and to the ring plane.

2. The securing ring of claim 1 wherein the throughbores extend parallel to the axis of symmetry.

3. The securing ring of claim 1 wherein the lugs extend in a common plane extending perpendicular to the ring plane.

4. The securing ring of claim 3 wherein the common plane extends parallel to a tangential plane of the ring opening, with the tangential plane extending perpendicular to the axis of symmetry.

5. The securing ring of claim 1 wherein the ring ends are each broadened radially outwards, said lugs being formed by bending the radially outwardly broadened ring ends out from the ring plane.

6. The securing ring of claim 5 wherein the throughbores extend perpendicular to the ring plane before bending the ring ends to form the lugs.

7. The securing ring of claim 1 wherein the throughbores extend at a distance to the ring plane.

8. The securing ring of claim 1 wherein the throughbore of each lug is formed by a cylindrical hole traversing the lug.
