Abstract: A joint assembly includes an inner ring, an intermediate member housing the inner ring about a joint axis and, an outer body retaining the intermediate member. The intermediate member defines two first surfaces formed by cylindrical portions having the same first axis of revolution which intersects the joint axis. The outer body defines two surfaces formed by cylindrical portions having the same second axis of revolution. When the assembly is in an assembled state, the first axis of revolution coincides with the second axis of revolution and the first and second surfaces cooperate to enable the intermediate member to rotate relative to the outer body about the first axis of revolution but prevent the intermediate member from moving parallel to the joint axis or parallel to an axis orthogonal to the joint axis and to the second axis of revolution.

Abstract: A seal assembly is for sealing a space between a housing and a shaft rotatable about a central axis. The seal assembly includes a seal body connectable with the housing and having an inner circumferential sealing surface. The sealing surface has opposing axial ends and is slidably contactable with the shaft outer surface to define a sealing interface. An annular biasing member, preferably a garter spring, is disposed about a portion of the seal body and has a centerline. The biasing member exerts a biasing force directed radially inwardly toward the centerline, such that the seal exerts a contact pressure on the shaft. Further, the biasing member is angularly positioned on the seal body such that the contact pressure extends axially along the shaft axis to direct substances entering the sealing interface toward a proximal axial end of the sealing surface when the shaft rotates about the central axis.

Abstract: A vibration and condition monitoring system with true digital signal processing based design, with very limited analog based general signal conditioning and integrated specific sensor conditioning and sensor power supply options. The device supports direct connection of eddy current probe systems to the module, due to a built-in driver and linearization functionality.

This response is then according to the invention recalculated into a linearization curve/transfer function. Specific sensor signal conditioning is not dependent on hardware, but only on embedded software (firmware). There is full sensor input support in an I.S. environment. Not only the common sensor input types from accelerometer, velocity sensor or eddy current probe system for both vibration and/or speed measurements.
