Timken Co. | Date: 2015-05-13

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.

A method of forming a component includes heating the component to a burnishing temperature above 500 degrees Fahrenheit, and burnishing a surface of the component while the component is at the burnishing temperature to densify the surface. The burnishing process at an elevated temperature may be integrated into other processes, such as the sintering or heat treating processes.

A device for supporting and installing a bearing assembly includes an inner ring having an inner ring axial face, an outer ring having an outer ring axial face and an outer diameter, and a plurality of rolling elements positioned between the inner ring and the outer ring. The device comprises a sleeve having an inner diameter sized and configured to receive and support the outer ring along the outer diameter, and a disc positioned within the sleeve. The disc includes a disc outer diameter sized and configured to permit sliding of the disc along the sleeve inner diameter in an axial direction of the sleeve and a disc face surface sized and configured to engage the inner ring axial face, or the outer ring axial face, or both when the bearing assembly is received in the sleeve.

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.

A sensor system including a movable member, a sensor, and an interpolator. The sensor is configured to generate a first output signal and a second output signal. The first output signal has a first phase angle, the second output signal has a second phase angle, and a first difference between the first phase angle and the second phase angle has a first value. The first value of the first difference includes an offset related to a mechanical incompatibility between the sensor and the movable member. The interpolator is configured to receive the first output signal and the second output signal. The interpolator is operable to apply a compensation factor to generate a third signal having a third phase. The compensation factor has a value that is based on the mechanical incompatibility between the sensor and the movable member.

A Hall effect sensor system for detecting magnetic fields includes a Hall effect sensor having a central body with a substantially square shape, a first pair of outwardly oriented and opposing arms projecting outwardly from opposing sides of the central body and a second pair of outwardly oriented and opposing arms projecting outwardly transverse from the first pair of arms to form a cross-shape. Each of the arms has a plurality of fingers projecting outwardly therefrom and electrodes are provided on the fingers. In operation, at least two electrodes on the first pair of opposing arms provide a path for bias current through the Hall effect sensor. An electrode on each of the second pair of opposing arms senses voltage formed in the Hall effect sensor by a magnetic field and provides an output to an amplifier.

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.
