Abstract
A collar bearing comprising a bearing shell and at least one thrust washer, whereby the at least one thrust washer is fixed on an outer convex circumferential surface of the bearing shell to define a joint site that extends between the convex outer circumferential surface of the bearing shell and a concave inner circumferential surface of the thrust washer, the at least one thrust washer being welded along a weld seam to the bearing shell such that the weld seam extends axially between an outer thrust facing and an opposite inner surface of the at least one thrust washer, and the weld seam extends over only a part of the joint site.
Claims12
A flange bearing comprising a bearing shell and at least one thrust washer, the at least one thrust washer being attached to a convex outer circumferential surface of the bearing shell, wherein a joint site extends between the convex outer circumferential surface of the bearing shell and a concave inner circumferential surface of the thrust washer, the at least one thrust washer being welded along a weld seam to the bearing shell in such a manner as to remain joined permanently during operation, the weld seam extending axially over only a part of the joint site from an end face of the bearing shell away from an outer thrust facing of the thrust washer, and without post-machining an angle is defined between the at least one thrust washer and the outer circumferential surface of the bearing shell having a value of 90° ±50′ (minutes), wherein a radial gap extends from said weld seam axially between the convex outer circumferential surface of the bearing shell and the concave inner circumferential surface of the thrust washer.
A flange bearing comprising a bearing shell and at least one thrust washer, the bearing shell having at least one circumferentially extending groove having a width extending axially inwardly from an edge of an inner circumferential surface with a chamfer portion and plane portion reducing the axial cross section of the bearing shell at the edge, the at least one thrust washer being attached to a convex outer circumferential surface of the bearing shell radially outwardly from said at least one groove, wherein a joint site extends between the convex outer circumferential surface of the bearing shell and a concave inner circumferential surface of the thrust washer, the at least one thrust washer being welded along a weld seam to the bearing shell in such a manner as to remain joined permanently during operation, the weld seam extending along the convex outer surface of the bearing shell between the rear side of the plane portion of the at least one groove and the concave inner circumferential surface of the thrust washer to increase the resiliency of the flange bearing and extending axially over only a part of the joint site terminating prior to said chamfer portion with a radial gap extending axially from the weld seam between said convex outer surface and said concave inner surface of the thrust washer, and without post-machining an angle is defined between the at least one thrust washer and the outer circumferential surface of the bearing shell having a value of 90° ±50′ (minutes).
A flange bearing comprising a bearing shell and at least one thrust washer, the at least one thrust washer being attached to an outer convex circumferential surface of the bearing shell, wherein a joint site extends between the convex outer circumferential surface of the bearing shell and a concave inner circumferential surface of the thrust washer, the at least one thrust washer being welded along a weld seam to the bearing shell in such a manner as to remain joined permanently during operation, the weld seam extending axially between an outer thrust facing and an opposite inner surface of the at least one thrust washer and extending over only a part of the concave inner circumferential surface and terminating prior to the inner surface of the thrust washer, wherein the convex outer circumferential surface of the bearing shell is spaced from and substantially parallel to the concave inner circumferential surface of the thrust washer.
