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 retainer (30) for maintaining a relative angular spacing of a plurality of rolling elements includes a body (34) having an annular portion (38) and a plurality of engaging portions (42). Each of the engaging portions is configured to engage at least one of the plurality of rolling elements. The body is made of a sintered powdered metal infiltrated with bronze.

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.

A method of determining a position on a magnetic track of an encoder includes providing a group of magnetic pole pairs that forms a portion of the magnetic track, recording a relative position within a first magnetic pole pair in the group using a first magnetic sensor proximate a high-resolution portion of the magnetic track, detecting adjacent pole junctions within the group of magnetic pole pairs with a second magnetic sensor positioned proximate a reference portion of the magnetic track, correlating the adjacent pole junctions with the first magnetic pole pair to determine a relative position of the first magnetic pole pair within the group, and calculating a local absolute position within the group using the relative position within the first magnetic pole pair and the relative position of the first magnetic pole pair within the group.

A labyrinth seal assembly, bearing assembly therewith, and method of construction thereof, has an outer rigid carrier and an inner sleeve. The carrier has an outer cylindrical flange and a radially inwardly extending leg and the sleeve has a cylindrical wall and a radially outwardly extending flange. A seal body is attached to at least one of the leg and the flange, wherein a labyrinth passage extends between the seal body and the sleeve, from an air side of the assembly to an oil side of the assembly, during normal use of the assembly.


A double row thrust bearing assembly (10) includes a bottom plate (11) having inner and outer conical raceways (12, 13), a top plate (14) with a flat raceway (15), and respective sets of identically formed inner and outer rollers (16, 17) mounted on respective inner and outer cages (18, 19). When the bearing is fully assembled, the apices of the inner and outer rollers directed at the same point (A) on an axis (X) of the bearing. Various relationships with respect to the size and shapes of the rollers are determined in order to maximize the bearing assemblys load carrying capacity while occupying the same spatial envelope as that of a single row thrust bearing assembly (BA) which can only support a lesser load.

A coupling (30) for the introduction of a bias voltage into a vacuum chamber. The coupling consists of a metallic ball bearing assembly (36), a bearing sleeve or cup (34), and an EMI shielding gasket (42) seated within the bearing sleeve or cup. The ball bearing assembly is fitted within the EMI shielding gasket, about a metallic shaft (32) which, in turn, is coupled to a source of the bias voltage. The bearing sleeve or cup is, in turn, coupled to a rotating component such as a platen, for receiving the bias voltage within the vacuum chamber.
