Abstract
A roller bearing assembly for use in a fracking pump crank shaft includes an inner ring being positioned an outer ring and a plurality of rolling elements disposed therebetween. Each of the rolling elements have a bore extending therein. The roller bearing assembly includes a cage having an annular disc with pins extending axially inward therefrom and into the bore. The pins are positioned on the annular disc so that the rolling elements are spaced apart from one another with a gap extending continuously therebetween. The gap is of a predetermined magnitude to maximize the number of rolling elements that fit between the inner ring and the outer ring to maximize load carrying capacity of the roller bearing assembly.
Claims9
A roller bearing assembly for use in a fracking pump crank shaft, the roller bearing assembly comprising:
- an outer ring having an inner raceway;
- an inner ring having an outer raceway, the inner ring being positioned at least partially in the outer ring;
- a plurality of rolling elements disposed between and in rolling engagement with inner raceway and the outer raceway, a first of the rolling elements having a first bore extending axially at least partially therethrough and a second of the rolling elements having a second bore extending axially therethrough;
- and
- a cage having a first annular disc positioned axially outward from the plurality of rolling elements, a first pin extending axially inward from the first annular disc and a second pin extending axially inward from the first annular disc, the first pin extending into the first bore and the second pin extending into the second bore;
- wherein the first pin and the second pin are positioned on the first annular disc so that the first of the plurality of rolling elements and the second of the plurality of rolling elements are spaced apart from one another with a gap extending continuously therebetween, the gap being of a predetermined magnitude to maximize the number of rolling elements that fit between the inner raceway and the outer raceway.
