Abstract:
A surface textured roller and a surface textured rolling element bearing comprising a plurality of micropores in a surface thereof is presented. The plurality of micropores may have a geometry selected from a hemisphere, a diamond shape, an ellipsoid, and a cone. The surface textured rollers may be used, for example, in a gear box and/or a wind turbine drivetrain.

Abstract:
An X-ray tube anode assembly and an X-ray tube assembly are disclosed that include an X-ray target and a drive assembly configured to provide an oscillatory motion to the X-ray target. The drive assembly is configured to provide an oscillatory motion to the target assembly.
Abstract:
A system and method for providing a sealing arrangement in an X-ray tube are provided. The X-ray tube includes a rotating portion having a plurality of ball bearings and a liquid metal within a housing having the ball bearings therein. The rotating portion is configured to rotate an anode. The X-ray tube further includes a sealing portion formed by a liquid metal vacuum interface configured in a radial direction to resist flow of liquid metal from the housing to a vacuum portion.
