| 20090199405 | Tripod type constant velocity universal joint - A tripod type constant velocity universal joint comprises an outer joint member having three track grooves with roller-guiding surfaces opposing each other circumferentially, a tripod member with three trunnions protruding in a radial direction, a plurality of rollers each inserted into a corresponding track groove and a plurality of rings each fitted on the corresponding trunnion for supporting the roller rotatably. An outer surface of the trunnion is formed to take on a straight shape in a longitudinal section and an ellipse shape in a cross-section. A contact ellipse shape between the trunnion and the ring is modified so as to render the radius of curvature r smaller while keeping an aspect ratio b/a stable in comparison with a contact ellipse shape being defined to minimize contact pressure between a ring inner surface and a trunnion outer surface. | 08-13-2009 |

The rolling bodies roll on rolling tracks of the bearing rings and are guided in cages in which markings are arranged on at least one rolling body. A sensor is attached to a cage and an evaluation unit is coupled to the sensor. To set the prestress and bearing play, the bearing arrangement is loaded with an axial force or tilting moment. The bearing arrangement is rotated by at least one full revolution, the rolling-body rotation is recorded by a sensor, and the outer or inner rings are adjusted in relation to the predefined prestress or hearing play. | 12-02-2010 |
| 20130145621 | SYSTEMS AND METHODS FOR PRELOADING A BEARING AND ALIGNING A LOCK NUT - An apparatus for providing a load on a bearing mounted to a shaft includes an attaching member and a press mechanism. The attaching member is releasably connected to the shaft. The press member is coupled to the attaching member and is configured to provide a compressive load to the bearing. The press mechanism includes an aligning arm configured to engage a shaft slot of the shaft to align the press mechanism relative to the shaft when the attaching member connects to the shaft. A lock nut is engageable with the shaft and has a plurality of engaging teeth configured to engage a plurality of keeper teeth of a keeper. The nut includes an outer surface having a plurality of markings corresponding to a plurality of roots of the plurality of engaging teeth to allow a user to selectively rotate the nut relative to the aligning arm to an engaging position such that a radially inner side of the keeper engages a slot of the shaft when the keeper teeth engage the engaging teeth of the nut. | 06-13-2013 |
| 20140020250 | FRICTION TORQUE BARCODE - A method to ascertain measured friction torque to a bearing and a method to reduce preload variation of a hearing pair or set. Friction torque of a bearing is measured at a known load and speed. The value of the measured friction torque is then printed in a data matrix that is then applied to the bearing that was measured. Prior to assembling the bearings on a shaft system, the data matrix is read. The targeted friction torque is calculated for the shaft system based on the desired assembly preload. The bearing preload is then set and verified by measuring the friction torque of the pair of bearings assembled on the shaft. As a result of the method, bearing friction torque variation is substantially mitigated. | 01-23-2014 |
| 20140144026 | ULTRAHIGH-INTEGRITY INTERLOCKING NUT AND WASHER SYSTEM FOR TRAILER AXLES - An interlocking nut and washer system complies with new standards identified in the Society of Automotive Engineers (SAE) Recommended Practice J2535, Setting Preload in Heavy-Duty Wheel Bearings, and with maintenance recommendations issued by the Technology Maintenance Council (TMC) Recommended Practice RP618, Wheel Bearing Adjustment Procedure. The system includes an improved inner washer, adjustment nut, intermediate washer, and outer nut that interlocks with the intermediate washer following the introduction of an established level of preload force by the adjustment nut. The inner washer isolates the adjustment nut from the inner bearing race to eliminate frictional wear. An increase in outer diameter of the inner washer provides an interference capability that serves as a safety factor to prevent separation of the wheel hub from the axle spindle in event of bearing failure. The inner washer includes markers to establish the final adjusted preload or the endplay position of the adjustment nut. | 05-29-2014 |

These methods and apparatus include preload monitoring devices whereby the mechanic can accurately monitor and regulate the preload on a bearing or bearing assembly. Aspects of the invention may also be used to adjust the endplay on a bearing or a bearing assembly. In one aspect, the preload on the bearing is transmitted through a housing having a fluid pressure that can be detected and monitored. An apparatus for precisely rotating a nut and a tool for precisely rotating a nut are also provided. A bearing retaining nut arrangement that permits the loading or evaluating of a bearing inner race is also provided. The bearing retaining nut arrangement includes a first load-setting nut, a lock washer, and a second jam nut that secures the arrangement to a shaft. | 10-02-2014 |
| 20150052758 | METHOD FOR SETTING THE PRELOAD IN A BEARING ASSEMBLY - A method for adjusting an axial preload in a bearing assembly that has two rolling-element bearings that are axially pressable against each other, each of the two rolling-element bearings including at least one bearing outer ring and at least one bearing inner ring and at least one row of rolling elements disposed between the at least one bearing outer ring and at least one bearing inner ring. The method includes a) driving the bearing assembly by rotating one of the bearing outer ring and the bearing inner ring while holding other bearing ring fixed and measuring the rotational speed of the circulation of the rolling elements about the bearing assembly axis or of a bearing cage about the stationary bearing ring, and b) changing the axial preload in the bearing assembly until a desired rotational speed has been obtained. | 02-26-2015 |
