Abstract: Two semi-annular members form an annular coupling. Each semi-annular member has a flexible center. A semi-annular shoe extends from each axial end of the flexible center. The shoes are bonded to the flexible center. The circumferential ends of the shoes have an axially extending cut-out embedded in the flexible center.
Abstract: A power steering pump and air conditioning compressor are axially aligned. Power from the power steering pump is provided to the air conditioning compressor through a coupler. The coupler has two axially spaced flexible discs separated by a spacer.
Abstract: A bushing and hub assembly are clamped together and clamped on a shaft by passing screws through an annular flange provided on the hub and into threaded openings in the bushing. The outside of the bushing is tapered and the inside bore of the hub has a taper which mates with the tapered outside of the bushing.
Abstract: The apparatus is used to make a magnet with a plurality of magnetic pole pairs. One or more pole pairs is formed by the apparatus as an initial step. Thereafter, additional pole pairs are formed by moving the apparatus with respect to the body to be magnetized or moving the body to be magnetized with respect to the apparatus. The apparatus is constructed so that previously magnetized portions of the magnetizable body are not demagnetized or significantly altered by the magnetization of adjacent parts of the magnetizable body.
Abstract: Rolling bearing assembly with sensor device of the type comprising at least one fixed ring, one rotating ring, rolling elements placed between said rings, a coding element co-rotating with the rotating ring, and a sensing element forming a unit with the fixed ring, characterized in that the coding element is placed in a circular groove on the face of a disk rotating in front of the sensor element mounted on the face of another, stationary disk.
Abstract: A high resolution encoder having a relatively high number of magnetic pole pairs with a magnetic flux strength sufficient for use in high resolution applications. Magnetic pole pair spacing varies from about 0.010 inch to about 0.050 inch with each magnetic pole pair having a magnetic flux in the range of about 2 gauss to about 700 gauss at a distance of 0.036 inch at a temperature of +20 degrees centigrade. This high resolution encoder is especially well-suited for use with magnetically encoded targets in sensor bearings.
Abstract: A shaft has rolling member bearings, a compression spring acting to urge the bearings toward the shallow groove in one end of the shaft and a ring fitting round said end, with a portion extending into the groove so that the spring force acts on the ring to assist in retaining the ring in the groove. In order to assist the retention of the ring in the groove, the ring may be provided with a chamfered surface on the outside of the ring at its end which is fitted to the groove. The groove may be axially longer than the ring portion extending into the groove so that the ring can move relative to the shaft. This is advantageous when, for example, tightening a steering wheel onto the shaft against the ring.
Abstract: An antifriction bearing assembly comprises a stationary outer race and a rotatable inner race with two annular rows of rolling elements between the races. A sensor assembly is mounted in the outer race so as to position a sensor between the races and the two rows of rolling elements, and an encoder is mounted on the inner race between the rows of rolling elements. Several sensor assembly and encoder configurations are included.

Abstract: An encoder is mounted on a seal of a bearing having a fixed ring and a radially spaced rotating ring. The encoder ring has circumferentially separated teeth on one of its radial surfaces which embed into an elastomer portion of the seal.
Abstract: A bearing with a rotating ring and a radially spaced fixed ring is mounted in the bore of a housing. A seal extends radially across the annulus between the bearing rings. An information sensor support is mounted in the housing and located adjacent one axial end of the bearing. The information sensor mounted in the information sensor support faces the seal. The seal has an axial portion with circumferentially separated holes. The axial portion extends toward the information sensor. The annular information sensor support has an axial portion extending toward the seal. This axial portion has a plurality of circumferentially separated radially extending retainers which pass through the seal holes and into an annular groove formed on the inside surface of the fixed ring.
Abstract: An antifriction bearing assembly has rolling elements and a magnetic encoder ring housed in an outer ring with two portions which can have different diameters. A sensor is removably attached to the outer ring in alignment with the encoder ring. Various seal assembly configurations may be used to seal the bearing while accommodating the sensor.

Abstract: A polymer cage of this invention comprises two annular end rims connected by multiple crossbars. This cage can be used in conjunction with metallic roller elements and bearing components to provide an improved wheel radial bearing. The cage is designed to provide improved lubricant flow through the bearing, and the cage can be manufactured by axial draw molding techniques.
Abstract: The hydrodynamic bearing assembly may be either a journal bearing or a thrust bearing. Bearing pads are located adjacent a shaft when a journal bearing or adjacent a collar on a shaft when a thrust bearing. The bearing pads are located on equalizing pads, two bearing pads for each equalizing pad. An elastomeric layer is disposed between the bearing pads and the equalizing pads.
Abstract: The spindle has a sleeve about a fixed shaft. Swing-type bearing pads are attached to the fixed shaft. The bearing pads are lubricated by flowing a lubricant through primary and secondary lubricating holes located in the fixed shaft.
Abstract: A manually controlled ball is rotatable in any direction at variable speeds to operate a pair of perpendicular rotatable shafts. Each shaft is rotated at a speed of and direction dependent upon the direction and speed of rotation of the manually operated ball. An encoder disk is mounted on each shaft. The direction and speed of the disk rotation is translated into electrical signals.
Abstract: One thrust race of a two-race thrust bearing has a magnetic field sensor mounted on a lip extending axially from the outside diameter of the thrust race. The other thrust race has a magnetic field source. The race with the magnetic field source rotates; the race with the sensor is fixed. The number of times alternate magnetic poles on the rotating thrust race is sensed by the sensor per unit of time indicates the speed of the rotating thrust race.
Abstract: A magnetic sensor bearing utilizes an adaptive threshold circuit for signal processing in order to compensate for external factors such as temperature, stress, aging, and external magnetic fields which all affect a fixed reference signal used with a comparator. As the magnetic sensor's output signal drifts due to these external factors, the adaptive threshold circuit causes the reference signals to drift in a complementary manner so that the magnetic sensor bearing continues to function properly in spite of the external factors.
Abstract: A cage and roller assembly in a hardened thrust bearing race is restrained within the race by heating a plurality of circumferentially widely separated parts of the race lip to soften the lip parts and bending the softened parts over the cage of the cage and roller assembly. An apparatus for assembling the thrust bearing includes a pair of electrodes located to apply a current through the lip to soften the lip and a form punch which is constructed to bend the softened part of the lip over a cage and roller assembly to an acute angle with respect to the rest of the lip.
Abstract: A shaft slides within a tube. A relatively high-rate leaf spring is positioned to exert its force against the outer surface of the shaft. The leaf spring provides optimal sliding force between the shaft and the tube with minimum friction, while also functioning to minimize rotational lash. Indents located on the exterior surface of the tube are directed radially inward to further minimize rotational lash.
Abstract: Axially spaced cams and bearing rings mounted on a tube are permanently secured to the tube by circumferentially spaced projections on the tube extending into grooves formed on the inside surfaces of the cams and bearing rings.
