Abstract: A gear spindle includes a shaft having a first gear cavity at a first end, an oil delivery path for delivering oil to the first gear cavity and an oil return path for carrying oil away from the first gear cavity. A first seal assembly is associated with the first end of the shaft for limiting leakage of oil from the first gear cavity, the first seal assembly including a sealing interface having one side in fluid communication with the first gear cavity and an opposite side in fluid communication with a fluid delivery path. The fluid delivery path may be connected to a source of pressurized air for reducing pressure differential across the sealing interface.

Abstract: A method and monitoring system for tracking operational parameters of a drive train of a monitored system includes a sensor unit affixed to the drive train. The sensor unit includes a sensor for generating an analog signal in response to an operating condition of the monitored system and an integrated local processor for processing the analog signal generated by the sensor. Actions of a sensor unit associated that is mounted from movement of a component of the drive system may be initiated via wireless receipt of instructions from another processing unit.

Abstract: The present invention relates to a method of manufacturing an all metal, single or dual, flanged composite railroad wheel for rollingly engaging a metal rail. A unitary metal railroad wheel having at least one radially extending wheel flange, for intermittently engaging the side surface of the rail, is provided with a metallic inlaid material having a coefficient of friction lower than the coefficient of friction of the wheel's main body. The inlaid low friction material forms an annular band circumscribing the inside surface of the wheel's radially extending flange.

Abstract: A chuck adapter attachable to a fixed chuck mechanism for converting the fixed chuck mechanism to a compensating chuck mechanism includes an attachment plate for connection to the head of the fixed chuck mechanism. The attachment plate includes a plurality of slots formed therein for alignment with respective drive jaws on the fixed chuck head. A plurality of adapter jaws are provided, each movable along a respective one of the plate slots, each adapter jaw including a movable clamping pin extending therefrom, and each adapter jaw including a hydraulic displacement member which reacts to movement of the clamping pin. A hydraulic circuit is provided in fluid communication with each of the hydraulic displacement members for maintaining substantially the same clamping force on each of the clamping pins as the clamping pins move.
