Abstract
An inner sliding surface for a radial plain bearing, including four circle arcs in at least one cross section. A first arc and a second arc of the four circle arcs lie on different sides of a longitudinal sectional plane which intersects a third arc of the four circle arcs, a fourth arc of the four circle arcs and a common center point of the third arc and the fourth arc. The first arc and a center point of the first arc lie on different sides of the longitudinal sectional plane, and the second arc and a center point of the second arc lie on different sides of the longitudinal sectional plane.
Claims8
An inner sliding surface for a radial plain bearing, comprising:
- four circle arcs in at least one cross section,
- wherein a first arc and a second arc of the four circle arcs lie on different sides of a longitudinal sectional plane which intersects a third arc of the four circle arcs, a fourth arc of the four circle arcs and a common center point of the third arc and the fourth arc,
- wherein the first arc and a center point of the first arc lie on different sides of the longitudinal sectional plane, and
- wherein the second arc and a center point of the second arc lie on different sides of the longitudinal sectional plane.
A method for manufacturing a component with an inner sliding surface, the method comprising:
- turning a workpiece such that the workpiece rotates about an axis which runs through a center point of a first circle arc of the inner sliding surface;
- turning the workpiece such that the workpiece rotates about an axis which runs through a center point of a second circle arc of the inner sliding surface;
- and
- turning the workpiece such that the workpiece rotates about an axis which runs through a common center point of a third circle arc and a fourth circle arc of the inner sliding surface,
- wherein the first circle arc and the second circle arc lie on different sides of a longitudinal sectional plane which intersects the third circle arc, the fourth circle arc, and the common center point of the third and fourth circle arcs,
- wherein the first circle arc and the center point of the first circle arc lie on different sides of the longitudinal sectional plane, and
- wherein the second circle arc and the center point of the second circle arc lie on different sides of the longitudinal sectional plane.
