Abstract: A bearing assembly includes an outer ring having an outer raceway and an inner ring having an inner raceway and a flange defining an outer diameter of the inner ring. A plurality of rolling elements is retained between the outer and inner rings on the outer and inner raceways. A cage has first and second side rings interconnected by a plurality of bridges to form a plurality of windows, each window receiving a respective rolling element to maintain relative spacing between adjacent rolling elements. At least some of the bridges include a projection on a radially inner side such that the plurality of proj ections together define an inner diameter of the cage, the inner diameter of the cage being smaller than the outer diameter of the inner ring to create interference and deformation of the cage as the cage is installed over the flange of the inner ring.

Abstract: A method and apparatus for sensing magnetic field strength with a pair of Hall effect sensors includes sampling a sensed voltage for the Hall effect sensors during a first phase and combining the sensed voltage. During a second phase, obtaining sensed voltages for the Hall effect sensors and combining the sensed voltages. The sensed voltages from the first phase and the second phase are combined to obtain a summed voltage and remove the Hall effect sensor and amplifier offset error value. In one arrangement, the summed voltage corresponds to the sensed Hall voltage of the first Hall effect sensor added to the Hall voltage of the second Hall effect sensor. In another arrangement, the summed voltage corresponds to the sensed Hall voltage of the first Hall effect sensor subtracted by the sensed Hall voltage of the second Hall effect sensor. Changes in the summed voltage with respect to a reference voltage are counted to determine the speed of a rotating shaft having magnets or a similar arrangement.

Abstract: A roller bearing (10) defines a bearing axis (34) and a radial plane (52) oriented parallel with the bearing axis. The roller bearing (10) includes an inner ring (42) having an inner raceway (44) and an inner flange (46) extending from the inner raceway. The inner flange (46) includes an inner guide surface (48). The roller bearing (10) also includes a plurality of rollers (22) in rolling engagement with the inner raceway (44) about the bearing axis (34). Each roller (22) includes a first end surface (24a) in engagement with the inner guide surface (48) of the inner flange (46) as the plurality of rollers (22) move relative to the inner ring (42). The first end surfaces (24a) of each roller (22) define a curvature such that a ratio of a first principal effective curvature (Rx) radius in a plane perpendicular to the radial plane (52) and a second principal curvature radius (Ry) in the radial plane (52) is no less than 3.0.

Abstract: A sensor system including a clock generation module, a sensor, a conditioning module, and an output module. The clock generation module is configured to generate a modulation signal and an output sampling signal. The modulation signal has a modulation frequency, and the sampling signal has a sampling frequency. The sensor is configured to generate an output signal having an output value. The output signal is modulated by the modulation signal, and the output value includes a sensor output value and an offset value. The conditioning module is configured to receive the output signal, condition the output signal, and generate a conditioned output signal including the sensor output value and the offset value. The output module is configured to receive the conditioned output signal and the output sampling signal. The output sampling signal is operable to sample the conditioned output signal at a value that corresponds to the sensor output value.

Abstract: A bearing assembly having an inner race ring (14) that defines an inner raceway and an outer race ring that defines an outer raceway on which the plurality of rolling elements (22) roll. The bearing raceways are machined using surface finishing operations to create preferred surface profiles and textures for improving lubrication performance. The profile of the raceway is initially created using a first grinding process to form a rough surface profile including a rough central band (34) and rough recessed side bands (38). A second grinding process is used to smooth the central band. This raceway surface profile increases lubrication performance.

Abstract: An apparatus for magnetic induction hardening of a workpiece includes a magnetic tool having a body portion formed of a generally non-magnetic material. The body portion has a surface configured to be positioned in close proximity to the workpiece being hardened. The apparatus further includes a magnetic arrangement coupled to the body portion at or adjacent the surface of the body portion and configured to provide regions of alternating polarity. A workpiece holder is configured to support the workpiece in close proximity to the surface of the magnetic tool. A drive arrangement for rotating the magnetic tool relative to the workpiece holder about an axis of rotation is provided to induce heating of the workpiece to achieve a temperature in the austenitic range of the workpiece resulting in hardening of the workpiece through a microstructural transformation.

Abstract: A method of coating spherical components with a coating process in which the spherical components have a surface area includes positioning the spherical components within a containment boundary on a moving member and positioning the moving member within a chamber. The method includes reducing the pressure within the chamber to less than one atmosphere. The method also includes revolving the moving member about a longitudinal axis. The method further includes oscillating the moving member in a direction of the longitudinal axis and commencing the coating process. The oscillating and revolving produce motion of the spherical components within the containment boundary such that an entirety of the surface area of each component is exposed to the coating process.
