Antifriction roller bearing

In a rolling bearing assembly defining a bearing axis and including an inner race, an outer race disposed about the inner race and concentric with the bearing axis, and a plurality of rolling bearings interposed between the inner and outer races, with the rolling bearings each comprising an elongate roller defining a shank intermediate the ends thereof, the improvement wherein:

• the inner race is formed to define an inner raceway thereabout,
• said inner raceway and said shanks of said rollers being formed to define right flanges and right grooves in substantially complementing interfitting relation forming the area of rolling engagement of the rollers with the inner race raceway,
• said rollers each defining a thrust bearing surface at either end of the same that is angled relative to the longitudinal axis of the respective rollers, and
• radial load transmitting surfacing in circumambient relation about the respective rollers,
• said areas of said flanges and grooves of said roller shanks forming a plurality of thrust transmitting faces that are angled relative to the longitudinal axis of the respective rollers,
• said outer race defining an outer raceway surface thereabout on which said roller surfaces and surfacing respectively ride in rolling engagement therewith, with those of said outer race surfaces on which said roller thrust bearing surfaces ride being aligned therewith transversely of the bearing assembly,
• and with said outer raceway intermediate the ends of said rollers being a surface of revolutions that is smoothly contoured axially of the bearing assembly,
• said roller bearing surface angulation being greater than said thrust transmitting face angulation.

In a rolling bearing unit defining a bearing axis and including an inner race, an outer race disposed about the inner race and concentric with the bearing axis, and rolling bearings interposed between said races in load transmitting relation thereto, the improvement comprising:

• said outer race defining a raceway thereabout having a pair of thrust resisting surfaces spaced apart axially of said bearing,
• said rolling elements each comprising a roller having a shank defining adjacent either end of same a thrust bearing surface that is angled relative to the axis of the roller, which bearing surfaces of the respective rollers ride on the respective outer raceway surfaces in substantially complementing, force transmitting relation thereto,
• said outer race thrust resisting surfaces being of circular contour transversely of the bearing axis and across the area of same that is engaged by said rollers,
• with said areas of said outer race thrust resisting surfaces each being a surface of revolution that is smoothly contoured axially of the bearing assembly,
• said inner race being formed to define a raceway thereabout,
• said inner race raceway and said rollers intermediate said roller ends being formed to define right flanges and right grooves in substantially complementing interfitting relation forming the areas of rolling engagement of the rollers with the inner race raceway,
• said rollers and said outer race defining radial load transmitting surfacing in which the roller surfacing thereof is in rolling engagement with the outer race surfacing thereof,
• said areas of said flanges and grooves of said roller shanks forming a plurality of thrust transmitting faces that are angled relative to the longitudinal axis of the respective rollers,
• with said roller bearing surface angulation being greater than said thrust transmitting face angulation.
