Patent ID: 7698818

Claim:
A method for at least one of assembling and adjusting at least two bearing portions in a fluidal mini to micro component, said fluidal component comprising a stator and at least one rotor, said rotor being supported at one of said bearing portions relative to said stator to be rotatably supported, wherein (a) a first sleeve is inserted in said stator for forming one of said bearing portions, said first sleeve is inserted in said stator as a first bearing sleeve and comprises an inner surface and an outer surface and is comprised of one of hardened steel, ceramic and hard metal; (b) said first bearing sleeve being prior to inserting into said stator, a separate bearing component comprising an inner bearing surface as said inner surface, and said inner surface is mechanically micro-finished prior to inserting into said stator, said microfinishing being one of grinding, honing and lapping; (c) said outer surface of said first bearing sleeve is brought into a mechanically permanent connection with said stator; and (d) wherein a second bearing body shaped as a second bearing sleeve and having an outer surface is inserted into the said stator, to assemble and adjust the bearing portions of said fluidal component, wherein each bearing sleeve defining an own axis, as eccentric or radially offset axes relative to each other, and obtain two bearing supports in an axial distance as non-identical axial positions for a shaft and an outer rotor as said rotor; (e) wherein said outer surfaces ( 10 a , 11 a ) of said first bearing sleeve ( 11 , 10 ) is inserted into a first receiving portion of said stator ( 30 ), said first receiving portion having a larger inner dimension, and a gap ( 13 ) or an irregular interspace between said inserted first bearing sleeve and said receiving portion is provided with a hardenable filling material ( 12 ), said filling material hardening after being filled into mechanically permanent connect said first bearing sleeve with said stator ( 30 ), and said hardening is obtained by a chemical reaction in said filling material ( 12 ).
