A fuel flow control assembly for an aircraft engine. The assembly includes a gear arrangement having a shaft. Also included is a bearing structure operatively coupled to each shaft. Further included is a pressure pad disposed adjacent the bearing structure, the pressure pad having a radially extending port for receiving a fuel flow. Yet further included is a flow metering device in flow communication with the port of the pressure pad to restrict the fuel flow at a low pressure operating condition and open the port to increase the fuel flow at a high pressure operating condition.

A torque transmission comprising input and output shaft adapters. Pins disposed on an outer surface of the input shaft adapter. Each pin provides a curved pin portion oriented generally perpendicular to the input shaft adapter's longitudinal axis. The output shaft adapter provides a recess with a plurality of notches formed in the recess's periphery, wherein the recess is shaped and sized such that when the input shaft adapter is received inside the recess, each pin is received into a corresponding notch. The torque transmission further comprises torsional bearings interposed between the pins and the notches, each torsional bearing providing a curved laminate portion such that the curve laminate portions contact the curved pin portions when the pins are received into their corresponding notches. The torsional bearings may further provide flat laminate portions that contact the notch when the pins are received into the notches.

A camshaft may comprise a main shaft, on which at least two sliding cam pieces are accommodated in a rotationally fixed and axially displaceable manner, wherein the sliding cam pieces each comprise a carrier tube, on which are seated cam groups each comprising at least two cam tracks for valve-control purposes, as well as an adjustment element that can be brought into operative connection with an actuator for axial displacement of the two sliding cam pieces. A method for assembling such a camshaft may involve providing a module body with bearing bridges that receive the camshaft in a rotatable manner, inserting a first sliding cam piece into a first bearing bridge, connecting the first sliding cam piece to the adjustment element, inserting a second sliding cam piece into a second bearing bridge, and connecting the second sliding cam piece to the adjustment element with the aid of an axial adjustment distance of at least one of the sliding cam pieces in the bearing bridges.

An ABS encoder arrangement for a driven wheel bearing unit, with a multi-pole ring, a sensor device with a sensor head, and an annular cap element that has an annular wall portion which shields a cap interior against the exterior. The annular wall section extends through an intermediate region lying between the multi-pole ring and an end face of the sensor head. An extension concentric with the axis of rotation of the multi-pole ring and extending axially over a circumferential area of an articulated shaft head is connected to the annular wall section on a side facing away from the multi-pole ring. In the end portion of the extension facing away from the multi-pole ring and extending over the articulated shaft head, the extension forms a circumferential profile that radially stiffens the extension and forms an annular edge which extends into a circumferential groove of the articulated shaft head and forms a channel cross-section open to the outside.

A device including a sealing assembly having a first annular shield constrainable to a rotating first member, a second annular shield facing the first shield and constrainable to a stationary second member, and an annular seal supported by the first shield and provided with annular lips cooperating with the second shield. The device has a signal generator device having a third shield constrainable to the first member and an annular signal generator element arranged facing the first and the second shields; wherein the first shield has a flange portion, having on a side of the first shield, a first and a second L-fold in opposite directions which delimit a first annular surface facing the annular lips and the second shield; wherein the annular signal generator element is delimited towards the second shield by a second annular surface facing the annular lips forming an obtuse angle with the first annular surface.
摘要:
A sealing element for a bearing, in particular a rolling contact bearing, and to a bearing, in particular a rolling contact bearing. The sealing element has a sealing composed of an elastic material, at least one support element composed of a rigid material, an IC identification, and an antenna for the IC identification. The at least one support element is formed from a non-metallic material such that the sealing element remains sufficiently stable mechanically and the operation of the antenna suffers little interference.
摘要:
A rolling element bearing comprises a groove with preferably an indentation in the bottom down the middle of the groove all around the bearing. The groove is to both accommodate a Bragg grated optical fiber and to increase the perceived sensitivity of the optical fiber by weakening the bearing and thereby creating larger deformation for specific loads/vibrations than if the groove was not there.

A wheel bearing apparatus incorporating a rotational speed detecting apparatus has an axially extending through bore formed in a mounting portion. A bottomed cylindrical sensor receptacle is integrally molded with the through bore. The sensor receptacle is press-formed from a non-magnetic steel sheet. The bottom portion of the sensor receptacle is arranged to oppose the pulser ring via a predetermined axial gap.

This wheel support bearing assembly includes an outer member, an inner member, and a plurality of rows of rolling elements between opposed rolling surfaces in both members. At least one sensor unit is provided on the outer diametric surface of the outer member, which is stationary. The sensor unit is made up of a strain generating member having two or more contact fixing segments adapted to be fixed to an outer diametric surface of the outer member in contact therewith and a sensor fitted to the strain generating member for detecting a strain induced in this strain generating member. A groove is provided in the outer diametric surface of the outer member at a location adjacent to the neighboring two contact fixing segments of the sensor unit.
