Abstract
A plain bearing includes an outer sliding surface element and an inner sliding surface element enclosed by the outer sliding surface element. The outer sliding surface element is divided along a substantially planar surface that includes the main axis of the sliding bearing and is formed with at least one radially encircling groove on the outer surface. A rubber-elastic or elastomeric is inserted in the at least one groove such that the ring holds together or retains the divided outer sliding surface element.
Claims19
A plain bearing comprising:
- an outer sliding surface element divided along a substantially planar surface that includes a main axis of the plain bearing and is formed with at least one radially encircling groove on the outer surface;
- an inner sliding surface element enclosed by the outer sliding surface element;
- and
- a rubber-elastic ring disposed within the at least one groove of the outer surface element and configured to hold together the divided outer sliding surface element;
- wherein the outer sliding surface element has two axial ends, the at least one groove has a depth, and the at least one groove is disposed in an axial end region of the outer sliding surface element so as to be spaced from one of the two axial ends of the outer sliding surface element by a distance of at least a value of the depth of the groove.
A plain bearing comprising:
- an outer sliding surface element having an inner, concave sliding surface extending circumferentially about a central main axis of the plain bearing, an outer surface extending circumferentially about the main axis and at least one radially encircling groove extending inwardly from the outer surface, the outer sliding surface element being divided along an axial plane including the main axis so as to form two semicircular outer element portions;
- an inner sliding surface element disposed within the outer sliding surface element and having an outer, convex sliding surface extending circumferentially about the main axis and slidably disposed against the sliding surface of the outer sliding surface element;
- and
- an elastomeric ring disposed within the at least one groove of the outer surface element and configured to hold together the two semicircular outer element portions of the outer sliding surface element;
- wherein the at least one groove has a depth with a value and is located within an axial end region of the outer sliding surface element so as to be spaced from an axial end of the outer sliding surface element by a distance, the spacing distance having a value of at least the value of the depth of the groove.
A plain bearing comprising:
- an outer sliding surface element having two axial ends and being divided along a substantially planar surface that includes a main axis of the plain bearing and is formed with at least one radially encircling groove on the outer surface, the groove being spaced axially apart from one of the two axial ends and being partially defined by two radial surface sections;
- an inner sliding surface element enclosed by the outer sliding surface element;
- and
- a rubber-elastic ring disposed within the at least one groove of the outer surface element and configured to hold together the divided outer sliding surface element, the ring being deflectable to fit over the outer sliding surface element and then contractable so as to be installed within the groove.
