DETAILED DESCRIPTION OF THE INVENTION

(9) The present bearing fastening ring 1 can be a semi-circular element having an outer diameter, an inner diameter and a bearing face 3 for receiving a bearing 10, the semi-circular element defining a central shaft axis 14, through which a horizontal centerline 8e and a vertical centerline 15 both bisect the central shaft axis 14 and are normal to one another.

(10) Scaling profiles 2 of different diameters are formed in the bearing face 3, the scaling profiles of different diameters being of diameters less than the outer diameter of the semi-circular element and greater than the inner diameter of the semi-circular element.

(11) Grounding ring apertures 8 are located in the semi-circular element. Cover assemblies 16 extend out from the outer diameter of the semi-circular element. Bracket assemblies 17 extend out from the outer diameter of the semi-circular element.

(12) The present invention features the bearing fastening fastening ring 1 used in rotating electrical machines, manufactured in aluminum, steel or cast iron in a semi-circular shape. The ring 1 is positioned over a shaft 11, not requiring any additional tools for insertion or removal of the bearing 10 during the assembly, installation or maintenance phases of the rotating electrical machine.

(13) The ring 1 has cover assemblies 16 with holes 18 as shown in FIG. 1, and the ring 1 is fastened to a cover 9 by means of two symmetrical and parallel central holes 13 as shown in FIGS. 2, 8, that are designed to align with holes 18, one hole 13 in each external end of the center horizontal line 8e, wherein at least two fastening elements 12 traverse the holes 13, 18 and remain in contact with the side of the external bearing ring 10 to be locked, according to the bearing size, with the contact taking place on one of the scaling profiles 2 designed for this purpose.

(14) Each scaling profiles 2 is designed for a different bearing size, preventing assembly issues or lack of contact area to support the side of the external bearing ring 10. There are at least two symmetrical and parallel grounding ring apertures 8 (FIGS. 3, 5) for fastening the shaft grounding, located at the ends of the center horizontal line 8e of the bearing fastening ring 1, enabling direct fastening of a grounding ring 4 onto the bearing fastening ring 1 by using at least two fastening elements 8a, e.g., screws.

(15) Another alternative for applying the present invention is shown in FIG. 3 by added means of four symmetrical bracket assemblies 17 (having holes 6) located at the ends of its diagonally traced center line 6e, which enable fastening a two-tier grounding ring 5 to the bearing fastening ring 1 through clamps 6a fastened to the bracket assemblies 17 or by fastening elements 6b, e.g., screws through holes 6.
