Abstract
An end-frame of an electro-dynamic machine includes a bearing housing defining an annular bearing cavity for rotatably supporting a rotor shaft about an axis. A support body is coupled to the bearing housing. The support body has a terminal end and a base end opposite the terminal end. The base end includes a first radial support surface having a first diameter, a second radial support surface having a second diameter, and an annular wall axially disposed between the first radial support surface and the second radial support surface. A radial extension extends radially from the support body adjacent the terminal end. A mounting member extends axially from the radial extension portion. The mounting member defines an aperture for receiving a BX fitting.
Claims20
An electro-dynamic machine comprising:
- a rotor shaft extending along an axis;
- a first end frame rotatably supporting the rotor shaft at a first axial position;
- a substantially cylindrical main frame member coaxially disposed about the rotor shaft frame and having a first end and a second end, the first end coupled to the first end frame, the main frame having one of a first diameter and a second diameter;
- a bearing housing defining an annular bearing cavity for rotatably supporting the rotor shaft at a second axial position;
- a first support member disposed radially outwardly of the bearing housing, the first support member including a first radial support surface for engaging the second end of the main frame member;
- a second support member disposed radially outwardly of the first support member and axially displaced from the first support member, the second support member including a cylindrical body with a terminal end, a base end opposite the terminal end, the base end including a second radial support surface for engaging the second end of the main frame member and a radial extension portion extending radially from the cylindrical body;
- and
- a mounting member extending axially from the radial extension portion, the mounting member defining an aperture for receiving a BX fitting.
