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.

Abstract: A roller assembly includes an outer ring having an interior having an inner surface extending an overall axial length between first and a second axial ends. The inner surface has a radially inward facing bearing surface extending between first and second radially inwardly extending flanges. The roller assembly includes a one piece inner member extending into the interior and having a groove formed therein between third and a fourth axial ends. A retaining ring is positioned in the groove. A first row of first rollers is positioned in the interior and between the retaining ring and the first radially extending flange. A second row of second rollers is positioned in the interior between the retaining ring and the second radially extending flange. An annular seal engages the inner member and has an overall axial width no more than 6% of the length of the outer ring.

Abstract: A tapered roller bearing assembly includes a one-piece inner ring that has two outer raceways oriented at angles relative to a longitudinal axis and a first outer ring with a first inner raceway and a second outer ring having a second inner raceway. The bearing assembly includes a spacer ring that has an axial width and is positioned around the inner ring and between the first and outer rings. A plurality of rolling elements is in rolling engagement with the first outer raceway and the first inner raceway. A plurality of rolling elements is in rolling engagement with the second outer raceway and the second inner raceway. The axial width is selectively established to obtain a predetermined axial clearance between the inner ring and the first outer ring and the second outer ring.

Abstract: A cage for a roller bearing includes a first annular portion and a second annular portion opposite the first annular portion and a plurality of pillars interconnecting the first annular portion and the second annular portion. Adjacent pairs of the pillars each define a pocket for holding rollers. Each of the pockets is configured to receive at least one roller. One or more radially outward facing concave roller support surface is formed in one or more of the pillars at a position proximate a radially outer edge of the pillar. The concave roller support surface is configured to radially outwardly support a portion of one of the rollers.
Abstract translation: 用于滚子轴承的保持架包括第一环形部分和与第一环形部分相对的第二环形部分和将第一环形部分和第二环形部分互连的多个支柱。 相邻的支柱对各限定一个用于保持辊子的口袋。 每个口袋被构造成容纳至少一个辊子。 在靠近柱的径向外边缘的位置处，在一个或多个柱中形成一个或多个径向向外的凹面滚子支撑表面。 凹辊支撑表面构造成径向向外支撑一个辊的一部分。
