Abstract

Abstract of the Disclosure A one piece formed metal flange mount for a spher-ical bearing in which the bearing is supported from a flange plate by an integral bearing receiving flange which has a spherical bearing receiving surface to support the bearing and allow it to align with an associated shaft.

Description

~Of~9~9 Background of the Invention This invention relates generally to a mount for spherical bearings and more particularly to a one-piece strong metal flange mount.
Present designs for flange mounts are generally of two types. One-piece machined cast flanges; and two-piece pressed steel flanges. The flange mounts include two, three and four or more holes for moun~ing the flange plate to an associated support.
The cast type machined are relatively expen-sive to process and machine to meet the typical heavy duty service for which they are intended. The surface to which they are attached must be relatively flat for ~
if it is uneven, the units may fracture when secured -to the attachment surface.
Pressed metal flange units are relatively economical. However, they are intended for light-duty applications. They generally do not support or accommodate heavy or large radial, thrust and moment loads. Generally, the flange mounts include central portions which project past the mounting face. This requires the user to provide an opening for accommodat-ing the projection. Pressed metal flange units are generally made of two or more mating pieces with atten-dant adaptations and assembly expenses. Those including lubrication fittin~s require means for preventing escape of the lubricant. Their most serious drawback is their inclination to bind the bearing they are
-2-~ 0695~9 intended to support because of radial mismatch of the separable mating halves that are clamped together and to a support.
Summary of the Invention According to the present invention there is provided a flange mount for a spherical bearing having a spherical outer surface including a flange plate and a bearing receiving flange formed from a single sheet metal piece of predetermined thick-ness and each of which has substantially the same thickness as said sheet metal with said bearing receiving flange extending outwardly from only one face of said flange plate and adapted to receive and hold a bearing therein, said bearing receiving flange having spherical inner and outer surface portions spaced from the one face of the flange plate, said spherical inner surface defining a re-entrant surface adapted to receive and conformably contact substantially the entire outer surface of said spherical bearing to support the bearing so that it cannot move radially or axially in either direction within the bearing receiving flange and yet permits the bearing axis to rotate to align with an associated shaft, the other face of said flange plate defining a mounting surface substantially perpendicular to the axis of said bearing receiving flange for mounting the flange on a supporting surface.

Description of Preferred Embodiment Referring to the figures, which show spherical bearing mounts in accordance with the invention, it is seen that the mounts are formed from a single sheet metal piece, as for example, by multistage forming in a press with appropriate dies and mechanisms.
Referring now specifically to Figure 1 through 6, ; 20 there is shown a two-hole bearing mount for spherical bearings. The mount includes a bearing mounting flange 11 whose inner surface 12 is substantially a surface of revo-lution to accommodate and hold an associated bearing. ;~
Furthermore, the surface 12 is of spherical configuration between the portions 13 and 14 to define a re-entrant bearing mount which, as will be presently described, serves to prevent movement of the associated bearing in the axial direction under axial thrust loads and in the 10~i95~i9 radial direction under radial loads but will permit misalignment under substantial moment loads.
The flange 11 is formed by causing the center of a sheet of metal to extend outwardly from the face 16 opposite the mounting face 17. A bearing is mounted in the spherical surface by inserting the bearing, with its axis perpendicular to the axis of the flange, into the bearing receiving flange through a mounting or insertion groove 18 formed at the rear of the flange.
The groove has a width which will accommodate the outer bearing race 19. After insertion, the bearing is rotated so that its axis is substantially coaxial Wi~l the flange axis and perpendicular to the mounting face 17. As is well known, the spherical bearing seat provides means whereby the bearing can be aligned with respect to the axis of the shaft.
, .
Preferably, the bearing mounting flange is provided with a circumferential grease receiving groove 21 which communicates with a grease fitting 22. The grease fitting 22 may be retained within the flange by threading or force fitting and communicate with the groove 21 by means of the recess 23 formed adjacent its end. In accordance with the present invention, the spherical seat which extends between the ends 13 and 14 has the end 14 spaced from the front face 17 such that , the end 15 of the bearing inner face 20 do not extend beyond the face of the flange 17. The ~lange therefore may be flush mounted to an associated supporting surface.

~ 1069S~9 It is seen that the thickness of the material at the flange mount surface 17 is substantially equal to the thickness of the flange mount 11 whereby to provide strength.
In those applications where additional strength may be required, the edges of the mounting plate may be bent along the same axis as the mounting flange 11. Referring to Figures 7 through 9, the flange plate is shown with bent edges 26. The edges are bent 0 in the same direction as the mounting flange 11 to add strength to the periphery of the flange plate when the mounting bolts are in place. The mounting member 9hOWn in Figures 7 through 9 is a three-hole mount in contrast to the two-hole mount previously described.
Referring to Figures 10 through 12, there is shown a four-hole bearing mount which includes the mounting flange 11 extending outwardly from the face 17. ~owever, in the embodiment shown in these figures, the upper end of the flange includes a rim 31 which adds strength to the end of the flange. In other respects the flange is of the type previously described and like reference numerals have been applied to like parts.
In certain applications it is desirable to provide additional regidity or strength to the mounting ~5 flange 11. For this purpose the flange is constructed with a portion of the flange plate extending adjacent to and engaging the end of the mounting flange 11.
Such an embodiment is shown in Figures 13 - 16 ~0~i9S~
in connection with a three-hole bearing mounting flange. The flange includes a bearing mounting flange 11 whose inner surface 12 is substantially a surface of revolution to accommodate and hold an associated bearing. The bearing is mounted in the spherical sur-face by inserting the bearing into the bearing receiving flange through a mounting slot or groove 18. The bearing is then rotated so that its axis is perpendi-cular to the mounting face 17. As is well known, the spherical bearing seat provides means whereby the bear-inq can be aligned with an associated shaft even when the axis of the bearing flange 11 is not accurately aligned with respect to the axis of the associated shaft. The bearing mounting flange may be provided with a grease lubrication fitting and a grease groove as previously described.
` After the flange is formed, the outer portions of the sheet or plate of material are formed or bent in the same direction as the bearing mounting flange substantially as shown in t~e drawings. When the outer portions are bent, the resulting flange will include the mounting face portion 17 and sides 27 extending between the mounting face portion substantially in the same direction and spaced adjacent to and substantially ` 25 parallel to the bearing receiving flange 11. The ends of the sides are bent inwardly to engage the bearing flange thereby providing a rigid support for the flange.
The sides 27 are bent inwardly by pressing areas such .S la6ss~s as 25 on the ends of the sides whereby the end portion of the bearing mounting flange is engaged as shown at 29, Figure 16. The webs or beams formed by the sides 27 effectively gusset or support between the bearing flange and the back side of the flange plate. This supports the bearing receiving flange against radial and thrust loads and twisting moment. The mounting face 17 may be provided with holes 31 to receive means, such as bolts or the like, for securing the flange to associated equipment. The edges 32 of the mounting face are bent in the same direction as the bearing mounting flange and provide rigidity to the mounting feet or surfaces. In vi~w of the fact that it is made out of plate or sheet material rather than bolted or otherwise secured, the flange may be welded to associ-ated equipment. The mounting slot permits insertion of the bearing after welding and easy replacement of worn bearings.
. ~ .
; It is apparent that the invention is applicable to two-hole, three-hole, four-hole or multiple hole mounts. The essential features of the invention are the fact that there is provided a substantially spherical mounting surface which engages the outer spherical bearing surface and prevents axial and lateral movement of the bearing to thereby minimize wear and deflection, yet facilitate controlled misalignment of the bearing insert. The plate material forming the mount is of substantially uniform thickness g ,- ~ ~ . . - , : . , 6gS~g throughout. The mount may be secured to an associated mounting surface by welding.
