Title: Construction of bearing boxes
Claims: What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims: 1. 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. 2. 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. 3. A bearing box as defined in claim 2 wherein said portion is a half disc for sealing the bearing recess against dust. 4. 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. 5. 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. 6. 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. 7. 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. 8. 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. 9. 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. 10. 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. 11. A bearing box as defined in claim 10 wherein said housing substantially consists of synthetic plastic material. 12. A bearing box as defined in claim 9 wherein said material is a polyvinylchloride. 13. A bearing box as defined in claim 9 wherein said material is a polyamide. 14. A bearing box as defined in claim 9 wherein said material is a polyethylene. 15. A bearing box as defined in claim 9 wherein said shell sections are injection molded to provide said shape and dimensions. 16. A bearing box comprising a plurality of shell sections substantially consisting of synthetic plastic material having a compression strength of at least about 390 kiloponds per square centimeter and jointly defining a recess for fitting bearing race means therein.
