Patent Number Title Of Patent Date Issued
7874255 Sleeve bearing for railway traction motor January 25, 2011
An improved sleeve bearing for locomotive traction motor that provides additional lubrication over and above that of the one central wick currently used. The sleeve bearing is provided with a recirculation system comprised of either at least two additional wicks located near the 6:00
7857101 Wick holder for a lubricating system of a locomotive traction motor support bearing December 28, 2010
An improved wick-holder for mounting a felt lubricating wick of a lubricating system for lubricating the axle journal surface supported in a support bearing of a traction motor used in a locomotive is provided with a plurality of oil-reservoir louver pockets or splash-cups molded or
7802656 Method and apparatus for improving the delivery of oil of a wick lubricating system for a locomo September 28, 2010
An improved wick-holder for mounting a felt lubricating wick is provided with a passive inertia-activated pump mounted for submersion in the axle-cap lubricant-reservoir at a level that ensures that for all levels of the reservoir, the pump inlet is submerged in the lubricant of the
7603955 Sleeve bearing for railway traction motor October 20, 2009
An improved sleeve bearing for locomotive traction motor that provides additional lubrication over and above that of the one central wick currently used. The sleeve bearing is provided with a recirculation system comprised of either at least two additional wicks located near the 6:00
7308856 Sleeve bearing for railway traction motor December 18, 2007
An improved sleeve bearing for locomotive traction motor that provides additional lubrication over and above that of the one central wick currently used. The sleeve bearing is provided with a recirculation system comprised of either at least two additional wicks located near the 6:00
7178463 Interior contour for bore of a friction support bearing of a railway locomotive traction motor February 20, 2007
A contour or profile of a bore of a locomotive traction-motor support bearing structure, where such profile preserves the currently center-loading of the upper load zone but moves inboardly the lower load zone to a more general central location. The profile of the bore for the suppor
7055439 Interior contour for bore of a friction support bearing of a railway locomotive traction motor June 6, 2006
A contour or profile of a bore of a locomotive traction-motor support bearing structure, where such profile preserves the currently center-loading of the upper load zone but moves inboardly the lower load zone to a more general central location. The profile of the bore for the suppor
6484403 Method of converting a traction motor with sleeve bearings to roller bearings November 26, 2002
A method for converting a locomotive traction motor originally equipped with sleeve bearings to roller bearings is provided. The ensuing method includes removing all parts of the original motor leaving only the motor frame. Recesses are then machined in the motor frame at both the pinion
