6. The bearing fastening ring of claim 1 comprising three scaling profiles to accommodate three different sizes of bearing.

7. A bearing fastening ring comprising: a metallic, curved, semi-circular bracket having an outer diameter, and inner diameter and a bearing face for receiving a bearing, the semi-circular element defining a central shaft axis, and having a horizontal centerline and a vertical centerline both bisecting the central shaft axis and normal to one another; scaling profiles of different diameters in the bearing face, 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; grounding ring apertures in the semi-circular element; cover assemblies extending out from the outer diameter of the semi-circular element; and bracket assemblies extending out from the outer diameter of the semi-circular element; wherein two grounding ring apertures lie on the horizontal centerline of the semi-circular element, one each on a left side and a right side of the semi-circular element; wherein two cover assemblies lie on the horizontal centerline of the semi-circular element, one each on the left side and the right side of the semi-circular element, each cover assembly comprising a through hole; and wherein four bracket assemblies lie vertically and horizontally symmetrically about the semi-circular element, two each on the left side and right side of the semi-circular element.

8. The bearing fastening ring of claim 7, wherein the two left side bracket assemblies are positioned, one rotationally above and one rotationally below, the left side cover assembly; and wherein the two right side bracket assemblies are positioned, one rotationally above and one rotationally below, the right side cover assembly.

9. A bearing construction assembly comprising: the bearing fastening ring of claim 1; a bearing cooperatively sized to one of the scaling profiles in the bearing face of the bearing fastening ring; a cover releasably secured to the bearing fasting ring via cover fastening elements and the cover assemblies of the semi-circular element; and a grounding ring releasably secured to the bearing fasting ring via grounding ring fastening elements and the grounding ring apertures in the semi-circular element.

10. The bearing construction assembly of claim 9, wherein: two grounding ring apertures lie on the horizontal centerline of the semi-circular element, one each on a left side and a right side of the semi-circular element; two cover assemblies lie on the horizontal centerline of the semi-circular element, one each on the left side and the right side of the semi-circular element, each cover assembly comprising a through hole; and four bracket assemblies lie vertically and horizontally symmetrically about the semi-circular element, two each on the left side and right side of the semi-circular element.

DESCRIPTION OF THE MODEL

[0020] The model features a bearing 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 the shaft (11), not requiring any additional tools for insertion or removal of the bearing during the assembly, installation or maintenance phases of said rotating electrical machine.

[0021] The ring (1) is fastened to the cover (9) by means of two symmetrical and parallel central holes (13), one in each external end of the center horizontal line (8e), by at least two fastening elements (12) and remains 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 (2) designed for this purpose.

[0022] Each scaling (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 holes (8) 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 the grounding ring (4) onto the bearing fastening ring (1) by using at least two fastening elements (8a), e.g., screws.

[0023] Another alternative for applying this model is added by means of four symmetrical brackets (6) located at the ends of its diagonally traced center line (6e), which enable fastening the two-tier grounding ring (5) to the bearing fastening ring (1) through clamps (6a) fastened to the brackets (6) or by fastening elements (6b), e.g., screws.
