Abstract
A bearing for receiving a journal comprises a bearing cup and a series of needle bearing elements interposed between the inner surface of the cup and the journal. Means are provided to bias the needle bearing elements into intimate rolling bearing contact with the outer bearing surface of the journal and bearing cup.
Claims5
A bearing for receiving a journal comprising:
- a bearing cup, a series of needle bearing elements interposed between the inner surface of said cup and said journal, means to form a slightly elliptical path for said needle bearing elements as they revolve around said journal thereby bringing said needle bearing elements into intimate rolling bearing contact with the outer bearing surface of said journal and the inner bearing surface of said cup, said journal is a trunnion formed on the ends of each of four equiangularly spaced arms of a cross in a cross and yoke type universal coupling, a bearing cup being mounted on each of said trunnions, said means to bias said needle bearing elements into intimate rolling contact with the outer bearing surface of said trunion and said inner bearing surface of said bearing cup is an insert member inserted within said bearing cup, said insert member having an outer cylindrical surface in contact with the complementary inner cylindrical surface of said bearing cup, the inner surface of said insert member being slightly elliptical with respect to the cylindrical outer surface of said trunnions, said needle bearing elements interposed in a bearing relationship between the cylindrical outer surface of said trunnions and the inner elliptical surface of said insert member.
