Process and tool for adjusting bearings
September 27, 2013. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 2101130 3672019 3785023 Method of adjusting pre-load on or clearance in bearing, and bearing assembly constructed by said method Bearing setting process Process for setting bearings Method for setting the axial end play of tapered roller bearings Method of compensating for tolerances in a rotary mounting having ball bearings Method of assembling two row angular contact bearing with improved axial end play Patent #: 5206993 InventorAssigneeApplicationNo. 126982 filed on 09/27/1993US Classes:29/898.09, Pre-usage process, e.g., preloading, aligning29/407.08, Pressure, force, or weight determining29/898.07MountingExaminersPrimary: Cuda, IreneAttorney, Agent or FirmInternational ClassB23P 015/00AbstractA bearing assembly which enables a hub to rotate on a spindle and has two single row tapered roller bearings, is adjusted by forcing the inner races or cones together with a spacer between them, all while the hub is off the spindle. This force, which is applied by an adjusting tool that fits through the cones much like the spindle, compresses the spacer and causes it to yield both elastically and plastically. The force is applied incrementally, and with each incremental advance the drag torque in the bearing assembly is checked by simply turning the adjusting tool. When the drag torque reaches a prescribed magnitude, the compressive force is removed and the adjusting tool withdrawn. Now the two races, the collapsed spacer and the hub, are installed on the spindle, followed by a spindle nut over the end of the spindle. The spindle nut clamps the two races and the spacer together, with the spacer establishing the distance that the races are separated--and hence the setting for the bearing assembly. | |
