Abstract
A plain bearing which is mounted in an end of a connecting rod consists of a pair of hemi-circular bearing halves of which axial ends are provided with flanges being integrally fixed by welding. The flanges improve the rigidity of the bearing halves. The big end of the connecting rod can have improved rigidity by mounting the bearing halves therein.
Claims3
A plain bearing for connecting rods, which is mounted on an end of a connecting rod, wherein:
- the plain bearing comprises a cylindrical bearing body and a flange which is provided on an axial end of the bearing body so as to extend along at least a quarter of the circumference of the axial end and project radially outwardly;
- wherein the flange is provided on the corresponding axial end by integrally securing a separate flange member to the bearing body;
- said cylindrical bearing body comprising a back metal and bearing layer, said back metal having a first thickness, and wherein said flange has a thickness greater than said first thickness.
A plain bearing for connecting rods, which is mounted on an end of a connecting rod, wherein:
- the plain bearing comprises a cylindrical bearing body and flanges provided on respective axial ends of the bearing body so as to extend along the overall circumference of the axial ends and project radially outwardly;
- wherein said flanges are provided on the corresponding axial ends by integrally securing separate flange members to the bearing body;
- said cylindrical bearing body comprising a back metal and bearing layer, said back metal having a first thickness, and wherein said flanges have a thickness greater than said first thickness.
