    Abstract: A method of determining the axial thrust on a thrust bearing assembly having a fixed and a rotating component in which a lubricant is being forced between the mated faces of the respective components and where zones of pressure are built up during operation, comprising monitoring the pressure of the lubricant between the mated faces. The invention also provides for determining the axial thrust by measuring the pressure differential of the lubricant between the mated faces or as it enters therebetween and as it emerges from between said faces. To measure the axial thrust on a pair of opposing thrust bearing assemblies, the pressure differential of the lubricant between the respective mated faces of the two assemblies is obtained. The axial thrust measurement can be utilized in a method of adjusting the axial thrust on the bearing assemblies by changing manually or automatically a balancing apparatus separate from the thrust bearings and their lubricant and used to adjust the net thrust on the bearings in response to the respective pressure measurement. The invention also encompasses the combination of suitable pressure measuring devices with thrust bearing assemblies with balancing apparatus to carry out the above measurement and control methods.

    Abstract: A drive mechanism module for use in a reciprocating pump converts rotational movement of a drive shaft to reciprocating movement of a reciprocating pump component transversely to the drive shaft. The drive mechanism module includes a connection member for attachment to the reciprocating pump component, a translating member that drives movement of the connection member in a first transverse direction while reciprocatingly translating in a second transverse direction relative to the connection member, a rotating member that rotates eccentrically with the drive shaft, and a rotary bearing assembly that permits rotation of the rotating member relative to the translating member while driving transverse movement of the translating member. The drive mechanism module may define a bearing fluid path for creating a hydrostatic or hydrodynamic fluid bearing at the interface of the connection member and the translating member.

    Abstract: A method for increasing load capacity on a porous aerostatic bearing through use of a two-phase fluid that is less viscous than lubrication oils and the bearing gap is of the size of air bearings. The porous material throttles vapor and liquid. As liquid goes through the porous media, the pressure drop from the porous media resistance causes it to vaporize. The increased volume flow in the bearing gap reduces the vapor flow rate through porous media, resulting in higher pressure in gap. As the vapor-liquid mixture escapes from bearing gap, another vaporization occurs at the end of bearings which retards escaping, and further increases pressure in the gap. The liquid portion of the two-phase fluid in the bearing gap increases the load capacity and stiffness, similar to hydrostatic bearings fed with liquid. The vaporization absorbs heat generated by bearing friction to allow higher relative speed between bearing surfaces.
