Abstract
A bearing, in particular to a self-aligning roller bearing, with a fastener of a sealing disc, which fastener increases the load-bearing strength. The bearing includes a bearing ring with an annular sealing disc which is connected to one of the two bearing ring end surfaces by a fastener which have a shank and a head, which has an enlarged diameter with respect to the shank, and the respective shanks reach through the bores which are made in the respective end surface. Here, the annular surfaces have a cylindrical contour, with the result that the other annular surface provides a raceway, wherein the raceway has a spherical contour, and the bore center axis of each bore in the bearing ring and in the sealing disc has an engaged profile which converges onto the cylindrical contour of the one annular surface.
Claims9
A bearing ring of a roller bearing, comprising:
- an outer annular surface;
- an inner annular surface;
- two end surfaces;
- an annular sealing disc connected to one of the two end surfaces;
- fasteners, each including a shank and a head, which has an enlarged diameter with respect to the shank, and respective ones of the shanks extend through bores in one of the end surfaces and the sealing disc connected thereto;
- wherein the outer annular surface has a cylindrical contour and the inner annular surface provides a raceway having a spherical contour, and a bore center axis of each said bore in one of the end surfaces and in the sealing disc has an engaged profile which converges towards the cylindrical contour while extending into the end surface;
- or
- wherein the outer annular surface includes a spherical contour and the inner annular surface includes a cylindrical contour, and a bore center axis of each said bore in one of the end surfaces and in the sealing disc has an engaged profile which diverges from the cylindrical contour while extending into the end surface.
