Abstract
Abstract A housing is provided for mounting a bearing adjacent a wall to support a rotatable shaft that projects perpendicularly through the wall. The housing has a thin-stock stamping that forms on end cap having an axially extending hub and a mounting flange projecting radially outward at one end of the hub. An axial bore is provided within the end cup for receiving a first longitudinal portion of a bearing. A thick plate has an opening therein for receiving a second longitudinal portion of the bearing that projects axially outward from the hub end adjacent the mounting flange. One side of the plate is mounted flush with the wall, and an opposite side of the plate is mounted flush with the mounting flange of the thin-stock stamping. The plate has a surface adjacent the bearing opening that radially supports the second longitudinal portion of the bearing. This plate extends radially outward from the bearing opening. Both the mounting flange and the plate have openings therein for receiving bolts that fasten the housing to the wall. In a preferred embodiment, the plate has a thickness that is more than double the thickness of the thin-stock stamping and about one-third the axial length of the hub.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
190 words
In a housing for mounting a bearing entirely on the outside of a wall to support a rotatable shaft that projects perpendicularly through the wall, said housing having a plurality of openings therein for receiving bolts that extend parallel to the shaft and fasten the housing to the wall, said housing having an end cap that can be formed by stamping from thin-stock, said end cap including an axially extending hub and a mounting flange projecting radially outward at one end of the hub, said end cap having an axial bore for receiving a first portion of said bearing, an improvement wherein said housing includes a flat thick plate having a bearing opening therein for receiving in wedging relationship a second portion of the bearing that projects beyond the end cap mounting flange, said plate extending radially outward adjacent the end cap mounting flange and thereby providing radial support for the bearing between the end cap and the wall, said plurality of openings for receiving bolts to fasten the housing to the wall being defined by a plurality of aligned openings in said end cap mounting flange and said plate.
Claim 2
Dependent Claim
190 words
In a housing for mounting a bearing entirely on the outside of a wall to support a rotatable shaft that projects perpendicularly through the wall, said housing having a plurality of openings therein for receiving bolts that extend parallel to the shaft and fasten the housing to the wall, said housing having an end cap that can be formed by stamping from thin-stock, said end cap including an axially extending hub and a mounting flange projecting radially outward at one end of the hub, said end cap having an axial bore for receiving a first portion of said bearing, an improvement wherein said housing includes a flat thick plate having a bearing opening therein for receiving in wedging relationship a second portion of the bearing that projects beyond the end cap mounting flange, said plate extending radially outward adjacent the end cap mounting flange and thereby providing radial support for the bearing between the end cap and the wall, said plurality of openings for receiving bolts to fasten the housing to the wall being defined by a plurality of aligned openings in said end cap mounting flange and said plate.
