Abstract
Abstract An outer race spacing member for locating two outer races of a roller bearing in position within a housing has a sealed oil mist passageway around its circumference which communicates with a lubricant supply channel extending through the housing. Mist nozzles extending from the oil mist passageway toward the areas to be lubricated in the bearing are positioned in spaced relation along the oil mist passageway. A lubricating oil mist is injected through the mist nozzles into the interior of the bearing under uniform pressure.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
205 words
A double-row roller bearing lubricating device for a housing having a bore and a bearing assembly including a pair of outer races fitted to the bore of the housing, inner race means and a plurality of rollers disposed between the outer races and said inner race means said lubricating device comprising a dry oil mist inlet extending through the housing into the bore between the pair of outer races, a spacing member disposed between the outer races; an annular passageway extending around the spacing member in the bore of the housing communicating with the dry oil mist inlet for receiving dry oil mist therefrom; a plurality of mist nozzle means in the spacing member opening inwardly and communicating with the annular passageway; packing means on both sides of the annular passageway for effecting oil-tight sealing between the outer periphery of the spacing member and the bore of the housing for confining dry oil mist in said passageway between the outer periphery of the spacing member and a corresponding inner face of the bore in the housing so that dry oil mist is discharged from the passageway through said mist nozzle means and expands to supply wet oil mist between the rollers of the bearing assembly.
Claim 2
Dependent Claim
205 words
A double-row roller bearing lubricating device for a housing having a bore and a bearing assembly including a pair of outer races fitted to the bore of the housing, inner race means and a plurality of rollers disposed between the outer races and said inner race means said lubricating device comprising a dry oil mist inlet extending through the housing into the bore between the pair of outer races, a spacing member disposed between the outer races; an annular passageway extending around the spacing member in the bore of the housing communicating with the dry oil mist inlet for receiving dry oil mist therefrom; a plurality of mist nozzle means in the spacing member opening inwardly and communicating with the annular passageway; packing means on both sides of the annular passageway for effecting oil-tight sealing between the outer periphery of the spacing member and the bore of the housing for confining dry oil mist in said passageway between the outer periphery of the spacing member and a corresponding inner face of the bore in the housing so that dry oil mist is discharged from the passageway through said mist nozzle means and expands to supply wet oil mist between the rollers of the bearing assembly.
Claim 3
Dependent Claim
40 words
The roller lubricating device of claim 1 additionally including a plurality of equidistantly spaced projections extending inwardly from the spacing member and wherein said mist nozzle means extend through the projections for changing dry oil mist into wet oil mist.
Claim 4
Dependent Claim
30 words
The roller bearing lubricating device as set forth in claim 2, wherein the mist nozzle means in the projections extending the spacing member are tapered in alternate opposite inward directions.
Claim 5
Dependent Claim
38 words
The roller bearing lubricating device as set forth in claim 1 additionally including a flange portion extending from the spacing member between the bearing rollers and wherein the mist nozzle means are equidistantly spaced in the flange portion.
Claim 6
Dependent Claim
135 words
A roller bearing assembly comprising a housing defining a bore, an inner race means, outer race means in said bore, rollers disposed between said inner race means and said outer race means, flange means protruding from one of said race means adjacent and engaging an end of each of said rollers, a dry oil mist inlet extending through said housing into said bore adjacent the outer race, an annular guide groove means defining an annular passageway adjacent the outer race and communicating with the dry oil mist inlet for receiving dry oil mist from the inlet, sealing means adjacent the annular passageway for confining the dry oil mist to the annular passageway and a plurality of mist nozzle means communicating with the annular passageway for directing oil mist against the rollers and said flange means.
Claim 7
Dependent Claim
135 words
A roller bearing assembly comprising a housing defining a bore, an inner race means, outer race means in said bore, rollers disposed between said inner race means and said outer race means, flange means protruding from one of said race means adjacent and engaging an end of each of said rollers, a dry oil mist inlet extending through said housing into said bore adjacent the outer race, an annular guide groove means defining an annular passageway adjacent the outer race and communicating with the dry oil mist inlet for receiving dry oil mist from the inlet, sealing means adjacent the annular passageway for confining the dry oil mist to the annular passageway and a plurality of mist nozzle means communicating with the annular passageway for directing oil mist against the rollers and said flange means.
