Bearing retainer
A bearing retainer for use with a bearing having an outside diameter which is to be received in the bearing retainer and to be mounted into a cavity having an inside diameter includes a bearing-engaging wall having a minimum inside diameter when the bearing retainer is in a non-deformed state approximately equal to but slightly less than the outside diameter of the bearing to be received therein, an outer cavity-engaging wall having a maximum outside diameter when the bearing retainer is in a non-deformed state approximately equal to the inside diameter of the cavity within which the bearing retainer is to be received, a web wall extending between and coupling the bearing-engaging wall and the cavity-engaging wall and wherein the bearing-engaging wall, cavity-engaging wall and web wall are fabricated from a material capable of elastic and plastic deformation so that upon insertion of the bearing into the bearing retainer the bearing-engaging wall is deformed to secure the bearing within the bearing retainer and upon insertion of the bearing retainer into the cavity the web wall is deformed to induce the cavity-engaging wall to exert a force against a side wall of the cavity to secure the bearing retainer within the cavity.
1 . A bearing retainer for use with a bearing having an outside diameter which is to be received in the bearing retainer and to be mounted into a cavity having an inside diameter, the bearing retainer comprising:
a frusto-conical inner bearing-engaging wall having a minimum inside diameter when the bearing retainer is in a non-deformed state approximately equal to but slightly less than the outside diameter of the bearing to be received therein;
an outer cavity-engaging wall having a maximum outside diameter when the bearing retainer is in a non-deformed state approximately equal to the inside diameter of the cavity within which the bearing retainer is to be received;
a web wall extending between and coupling the bearing-engaging wall and the cavity-engaging wall;
and wherein the bearing-engaging wall, cavity-engaging wall and web wall are fabricated from a material capable of elastic and plastic deformation so that upon insertion of the bearing into the bearing retainer the bearing-engaging wall is deformed to secure the bearing within the bearing retainer and upon insertion of the bearing retainer into the cavity the web wall is deformed to induce the cavity-engaging wall to exert a force against a side wall of the cavity to secure the bearing retainer within the cavity.
2 . The bearing retainer of claim 1 and further comprising a stop wall extending inwardly from a distal edge of the bearing-engaging wall.
3 . The bearing retainer of claim 1 wherein the web wall extends between a proximal edge of the bearing-engaging wall and a proximal edge of the cavity-engaging wall.
4 . The bearing retainer of claim 3 wherein a distal end of the cavity-engaging wall is spaced apart from the bearing engaging wall.
5 . The bearing retainer of claim 4 wherein a lip extends distally and radially inwardly from the distal end of the cavity engaging wall terminating in a free end displaced from the bearing-engaging wall.
6 . The bearing retainer of claim 5 wherein the bearing is configured to facilitate stamping the bearing retainer as a monolithic component from a sheet of metal.
7 . The bearing retainer of claim 6 wherein the sheet of metal from which the bearing retainer is formed has a thickness of between 0.025 and 0.035 inches.
8 . The bearing retainer of claim 6 wherein the metal from which the bearing retainer is fabricated is a low carbon steel.
9 . The bearing retainer of claim 8 wherein the metal from which the bearing retainer is fabricated is selected from the group of AISI 1008, AISI 1010 and AISI 1015 low carbon steel.
10 . The bearing retainer of claim 6 wherein the metal from which the bearing retainer is fabricated is stainless steel.
11 . The bearing retainer of claim 1 wherein the maximum outside diameter of the cavity-engaging wall in a non-deformed bearing retainer is slightly greater than the inside diameter of the cavity.
