Abstract
A track-roller bearing assembly is disclosed which includes a fixed inner ball race member having an outwardly facing arcuate peripheral bearing surface; an annular body of self-lubricating bearing material affixed to the outwardly bearing surface of said inner race; and a coaxial outer race which is rotatable about an axis of the inner race and anguarly displaceable relative to the axis of the inner race so as to accommodate track deflections or irregularities. The track-roller further includes a resilient element disposed between respective ends of the inner and outer races so as to bias the races back into axial alignment after they have been angularly displaced relative to each other.
Claims22
A track-roller bearing assembly comprising:
- an inner ball race member having a central axis and an outwardly facing arcuate peripheral bearing surface;
- an outer race member coaxial with said central axis of said inner race member and including a bearing portion having an annular arcuate surface, said outer race member being rotatable about said central axis of said inner race member and angularly displacable relative to said axis;
- and
- means for realigning said central axis of said outer race member with said central axis of said inner race member when said race members have rotated angularly relative to each other, said realigning means being mounted between and immediately adjacent the respective end portions of said inner and outer race members.
A track-roller bearing assembly comprising:

- an annular body of self-lubricating bearing material affixed to the bearing surface of said inner race member;
- an outer race member rotatable about an axis of said inner race member and angularly displacable relative to said axis of said inner race member, said outer race member including a bearing portion having an annular arcuate surface in sliding engagement with said bearing material;
- and
- means for realigning a central axis of said outer race member with said central axis of said inner race member when said race members have rotated angularly relative to each other, said realigning means being mounted between and immediately adjacent respective end portions of said inner and outer race members.
