Abstract
A roller bearing installation, in which one or more roller bearing assemblies (30A, 30B, 30C) are prepackaged in a housing (18) having corresponding recesses (28A, 28B, 28C) receiving each bearing assembly (30A, 30B, 30C). An angled gib plate (52A, 52C, 52C) is bedded in each recess, each gib plate (52) including an inclined section (54) mating with an inclined surface (58) on a bearing assembly cover (72) to allow a bearing depth adjustment by lengthwise adjustment of the bearing assembly (30) in its recess, enabling position adjustment of the supported structure (10) and bearing preload adjustment. Accurate alignment of the bearing assembly (30) is achieved by a ball plunger (100) urging the same against a guide surface (57) of the gib plate (52). A fixture (110) is used to precisely locate each gib plate (52A, 52B, 52C) in a recess (28) while a moldable bonding material (109) in which each gib plate (52) is bedded sets up. Electromagnetic coils (146, 148) are used to releasably hold each gib plate (52) on a respective locator arm (134, 136) during the process.
