Abstract: A sealing system for sealing a cylindrically shaped surface containing a first annular seal and a second annular seal. Each annular seal has a gap penetrating from the outer diameter to the inner diameter. The angle of the gap in the first annular seal and the angle of the gap in the second annular seal and the arrangement of the seals relative to an expander ring and a biasing ring minimizes leakage without the need for an anti-rotation pin or other means that would significantly decrease efficiency and reliability.

Abstract: A bearing system for a rotating vertical shaft includes a first ball bearing, having a first pitch diameter and a first axial stiffness and a second ball bearing having a second pitch diameter and a second axial stiffness. The first ball bearing is a deep groove Conrad bearing. The second ball bearing is an angular contact bearing. The first and second ball bearings are coaxial, secured to one another and rotatable together. The first pitch diameter is at least 1.5 times greater than the second pitch diameter. The bearing system has an axial stiffness ratio defined by the first axial stiffness divided by the second axial stiffness. The axial stiffness ratio is based on an axial preload force applied to the second outer ring such that an operating torque of the bearing system is within a predetermined range at temperatures from minus 40 to positive 85 degrees Celsius.

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 seal assembly for a bearing includes an inner seal member that has an annular ring with a first lobe extending therefrom and a seal receiving surface on a leg extending axially from the annular ring. The seal receiving surface has two seating areas. The seal assembly includes an outer seal member positioned radially inward from the leg and axially outward from the annular ring. The outer seal member has a pivot member which has a second lobe extending outwardly therefrom. The seal assembly includes a retaining ring that has a circumferential groove formed therein. The pivot member is pivotally seated in the groove so that the second lobe is moveable between the two first seating areas.

Abstract: A composite material having an alloy matrix including titanium, aluminum, niobium, manganese, boron, and carbon is disclosed. The composite material includes, by atomic percentage, 40.0% to 50.0% Al, 1.0% to 8.0% Nb, 0.5% to 2.0% Mn, 0.1% to 2.0% B, and 0.01% to 0.2% C. The composite material is doped with a solid lubricant such as MoS2, ZnO, CuO, hexagonal boron nitride (hBN), WS2, AgTaO3, CuTaO3, CuTa2O6, or combinations thereof. Components composed of the composite material exhibit increased ductility at room temperature and reduced fracture tendency, resulting in improved durability.

Abstract: A spheroidal joint for a tuned mass damper system includes a base having a concave seat and a lubricious liner secured thereto. The base defines a first mounting portion under the concave seat and a circumferential rim opposite the first mounting portion. The concave seat tapers radially outward to define a chamfer which terminates at a radially inner edge of the rim. The spheroidal joint includes an inner member that has a convex seat. The inner member has a second mounting portion extending from the convex seat and an indentation circumferentially extending around the inner member between the convex seat and the second mounting portion. The indentation cooperates with the chamfer for misalignment of the inner member relative to the base. The convex seat slidingly engages the lubricious liner.
