Patent number: 5810485Abstract: This invention is directed toward a bearing system for a rotating element, and more particularly directed toward an bearing system which provides an auxiliary bearing system if the primary bearing fails. Transfer of load from the failing primary bearing to one or more auxiliary bearings is initiated by conditions generated by the failing primary bearing such as abnormal heat generation or abnormal torque impulses. Alternately, the invention can be used to prevent primary bearing failure by transferring load to the secondary bearing system if the primary bearing is overloaded. The transfer of load is completely automatic requiring no human intervention. A signal or warning is, however, emitted by the bearing system to notify that loading has been transferred to one or more auxiliary bearings. The invention is directed toward an auxiliary bearing system for tapered roller bearings used in rail cars.Type: GrantFiled: December 29, 1997Date of Patent: September 22, 1998Assignee: W. L.

Patent number: 5366299Abstract: A hinge assembly for an articulated vehicle having front and rear frame portions joined at a pair of vertically aligned hinges. Each hinge includes a similar roller bearing assembly attached to the front frame portion and having a rotatable protruding trunnion. The rear frame portion includes recesses for receiving the trunnions and trunnion caps for retaining the trunnions. The trunnion of each bearing assembly includes a shoulder pin with a first bearing cone placed against the shoulder and a second bearing cone spaced apart from the first cone. A spacer ring received on the pin is biased against the second cone by an end cap secured to the end of the pin. A shim pack between the end cap and the end of the pin limits the amount by which the space between the cones may be to limit and control the pre-load of the bearing assembly.Type: GrantFiled: March 11, 1993Date of Patent: November 22, 1994Assignee: Wagner Mining and Construction Equipment Co.Inventor: Daniel L. Hughes

Patent number: 5358074Abstract: An adjusting device for aligning a drive pulley for an elevator leg or similar belt conveyor. The driving mechanism, normally perpendicular to the axis of the pulley, is pivotally mounted so that the drive shaft may be slightly tilted. The bearing block opposite the driven part of the shaft is mounted on shims to allow the movement of the axis of the shaft.Type: GrantFiled: December 6, 1993Date of Patent: October 25, 1994Inventor: Clayton S. Ellsworth

Patent number: 5286119Abstract: A bearing play adjusting assembly is useable to adjust the bearing play in an axle journal of a printing plate cylinder of a rotary printing press. A pressure plate is secured to an end of the axle journal and bears against an inner bushing. A shim plate is placed between the pressure plate and the axle journal end. The thickness of the shim plate can be changed to adjust the bearing play of the cylinder axle journal bearing.Type: GrantFiled: October 19, 1992Date of Patent: February 15, 1994Assignee: Koenig & Bauer AktiengesellschaftInventor: Christian M. M. Fischer

Patent number: 5129156Abstract: A motor support bearing assembly is provided for a live axle used in locomotives. A wheel is press fit on each end of the axle under high pressure, with a gear secured between the wheels adjacent the pinion end of the axle. The motor support bearing assembly is located between the plain end wheel at the commutator end and the axle gear at the other end, and includes a housing, a tapered roller bearing adjacent the plain end wheel, and another tapered roller bearing adjacent the axle gear. In the motor support bearing assembly process, a master spacer made of hardened metal is placed in a selected space in the assembly. The plain end wheel is pressed onto the axle under high pressure. Axial end play in the motor support bearings is set by applying a spike of additional pressure to the plain end wheel, pressing the bearings together tightly and in some cases pre-loading the bearings.Type: GrantFiled: December 20, 1990Date of Patent: July 14, 1992Assignee: General Electric CompanyInventor: Dale C. Walker

Patent number: 5115558Abstract: Apparatus for determining shim thicknesses used to position antifriction bearings on shafts located in recesses formed in a casing. The shafts, fitted with the bearings, are installed in the casing and located with compensating discs or shims. An apparatus plate of predetermined thickness is located between the flanges of two casing halves, split perpendicular to the shaft axis. An axial force measuring cell is fitted on the antifriction bearing and the two casing halves are clamped together with a predetermined load. Axial forces produced by the clamping action of the casing on the shafts are measured during operation and correlated with a predetermined, desired axial force by a computer. The optimum thickness of the compensating discs for the individual shafts is calculated from data supplied to the computer.Type: GrantFiled: May 3, 1990Date of Patent: May 26, 1992Assignee: Ford Motor CompanyInventors: Bodo Bernhardt, Jan Dijkhuis, Theo Molders
