Abstract

A rolling bearing assembly including a wire cage is provided. The assembly includes a radially inner ring including a first filling slot and a radially outer ring including a second filling slot. The first and second filling slots and a radial distance defined between radially inner ring and the radially outer ring are dimensioned to receive the spherical rolling elements. The wire cage includes first and second wires that extend around opposite axial sides of each of the spherical rolling elements in an alternating manner. The first and second wires overlap each other in areas between adjacent ones of the spherical rolling elements, and crimping elements affix the first and second wires together in each of the areas between the adjacent rolling elements.

First claim

What is claimed is:

1 . A rolling bearing assembly comprising:
a radially inner ring defining an inner race and including a first filling slot; a radially outer ring defining an outer race and including a second filling slot; spherical rolling elements supported between the radially inner ring and the radially outer ring, the spherical rolling elements running on the inner race and the outer race; wherein the first and second filling slots and a radial distance defined between a radially outer surface of the radially inner ring and a radially inner surface of the radially outer ring are dimensioned to receive the spherical rolling elements; and a wire cage including first and second wires that extend around opposite axial sides of each of the spherical rolling elements in an alternating manner, and the first and second wires overlap each other in areas between adjacent ones of the spherical rolling elements, and crimping elements affix the first and second wires together in the areas between the adjacent rolling elements.

2 . The rolling bearing assembly of claim 1 , wherein the first and second filling slots are semi-circular.

3 . The rolling bearing assembly of claim 1 , wherein the first and second wires are generally located at a pitch circle diameter of each of the spherical rolling elements.

4 . The rolling bearing assembly of claim 1 , wherein the crimping elements are formed from brass or copper.

5 . The rolling bearing assembly of claim 1 , wherein a diameter of the first and second wires is 5% of a diameter of the spherical rolling elements.

6 . A method of constructing a rolling bearing assembly with spherical rolling elements, the method comprising:
inserting the spherical rolling elements between inner and outer bearing rings, each of the inner and outer bearing rings including a filling slot through which the spherical rolling elements are inserted; weaving first and second wires of a wire cage around opposite sides of each of the spherical rolling elements in an alternating manner; overlapping the first and second wires with each other in areas between adjacent ones of the spherical rolling elements; inserting crimping elements in the areas between the adjacent ones of the spherical rolling elements; and fixing each of the first and second wires together with one of the crimping elements in each of the overlapping areas.
