Abstract

Hydraulisk aksiallager for en radielt montert aksel (1) med en flens (la) omfattende et ytre generelt aksialt tetningsrom (7) fonnet mellom flensen og en tetningsring (3), og et indre generelt radiell tetningsrom (9) fonnet mellom akselen og en tetningsring (5a) avgrenset i lagerhuset (5). Et hydraulisk trykkmedium tilføres gjennom ledning (D) til hulrommet (11) formet mellom tetningsrommene, hvorved mediet evakueres gjennom rommene under et betydelig trykkfall for å absorbere aksialbelastning utøvet på akselen. Det ytre aksiale rommet kan reguleres med et ytterligere trykkmedium som tilføres trykk-kammeret (5b) via ledning (D). Dette tillater regulering av trykket i hulrommet (11) og følgelig den aksiale belastning absorbert.Hydraulic thrust bearing for a radially mounted shaft (1) with a flange (1a) comprising an outer generally axial sealing space (7) formed between the flange and a sealing ring (3), and an inner generally radial sealing space (9) formed between the shaft and a sealing ring (5a) delimited in the bearing housing (5). A hydraulic pressure medium is supplied through line (D) to the cavity (11) formed between the sealing spaces, whereby the medium is evacuated through the spaces under a significant pressure drop to absorb axial load exerted on the shaft. The outer axial space can be regulated with an additional pressure medium which is supplied to the pressure chamber (5b) via line (D). This allows regulation of the pressure in the cavity (11) and consequently the axial load absorbed.
