Abstract
Abstract Two shell sections are injection molded of synthetic plastic material having high compression strength, to provide a housing for an outer race surface of a ball bearing or roller bearing. When the two sections are combined, inner surfaces of the housing provided thereby accurately fit bearing race surfaces to be held therein without machining or finishing these surfaces.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein, and additional recesses coaxial with said recess for said bearing race means; and seal ring means in said additional recesses.
Claim 2
Dependent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein, and additional recesses coaxial with said recess for said bearing race means; and seal ring means in said additional recesses.
Claim 3
Dependent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein, at least one of said shell sections have additional recess means for guiding lubricant fluid to said bearing race means.
Claim 4
Dependent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein, at least one of said shell sections have additional recess means for guiding lubricant fluid to said bearing race means.
Claim 5
Dependent Claim
22 words
A bearing box as defined in claim 2 wherein said portion is a half disc for sealing the bearing recess against dust.
Claim 6
Dependent Claim
25 words
A bearing box as defined in claim 3 wherein one of said sections has diametric groove means fitting a diametric edge of said half disc.
Claim 7
Dependent Claim
93 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein, each of said sections having a portion fitting one type of bearing race means such as the outer race of a thrust bearing, said portion having a thin peripheral element connecting said portions to another part of the section to permit breaking off of said portion so that said other part fits another type of bearing race means such as the outer race of a radial bearing.
Claim 8
Dependent Claim
93 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein, each of said sections having a portion fitting one type of bearing race means such as the outer race of a thrust bearing, said portion having a thin peripheral element connecting said portions to another part of the section to permit breaking off of said portion so that said other part fits another type of bearing race means such as the outer race of a radial bearing.
Claim 9
Dependent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; and annular inset means in said recess and having a spherically curved inner surface to fit self-aligning bearing race means.
Claim 10
Dependent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; and annular inset means in said recess and having a spherically curved inner surface to fit self-aligning bearing race means.
Claim 11
Dependent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; and annular inset means in said recess and having a cylindrically curved inner surface to fit preadjusted bearing race means.
Claim 12
Dependent Claim
46 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; and annular inset means in said recess and having a cylindrically curved inner surface to fit preadjusted bearing race means.
Claim 13
Dependent Claim
67 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; a housing surrounding said shell sections and holding the same so that they jointly define said recess, said housing having a spherically curved inner surface and said shell sections having spherically curved outer surfaces for self-alignment of said bearing race means.
Claim 14
Dependent Claim
67 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; a housing surrounding said shell sections and holding the same so that they jointly define said recess, said housing having a spherically curved inner surface and said shell sections having spherically curved outer surfaces for self-alignment of said bearing race means.
Claim 15
Dependent Claim
66 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; a housing surrounding said shell sections and holding the same so that they jointly define said recess, said housing and one of said shell sections having key and groove means for holding said sections against displacement relative to said housing.
Claim 16
Dependent Claim
66 words
A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material and jointly defining a recess for fitting bearing race means therein; a housing surrounding said shell sections and holding the same so that they jointly define said recess, said housing and one of said shell sections having key and groove means for holding said sections against displacement relative to said housing.
Claim 17
Dependent Claim
25 words
A bearing box as defined in claim 9 including a housing surrounding said shell sections and holding them so that they jointly define said recess.
Claim 18
Dependent Claim
