  • Patent number: 11015527
    Abstract: Aspects of the disclosure are directed to a rotatable shaft, and a plurality of bearings coupled to the rotatable shaft, where the plurality of bearings include a first bearing, a second bearing, and a third bearing, where the first bearing defines an axial first bearing centerline, where the second bearing defines an axial second bearing centerline, where the third bearing defines an axial third bearing centerline, and where the axial second bearing centerline is radially offset from the axial first bearing centerline and the axial third bearing centerline.
    Type: Grant

  • Patent number: 10094420
    Abstract: A squeeze film damper includes a static member and a whirling member positioned adjacent to the static member. A gap is formed between the static member and the whirling member. A pressurized oil reservoir is formed in the gap between the static member and the whirling member. A first low pressure oil reservoir is formed in a first cavity in the whirling member, wherein the first low pressure oil reservoir is positioned on a first end of the pressurized oil reservoir. A second low pressure oil reservoir is formed in a second cavity in the whirling member, wherein the second low pressure oil reservoir is positioned on a second end of the pressurized oil reservoir. A first primary seal is positioned between the first end of the pressurized oil reservoir and the first low pressure oil reservoir, and a second primary seal is positioned between the second end of the pressurized oil reservoir and the second low pressure oil reservoir.

  • Patent number: 6574865
    Abstract: A wheel bearing assembly for supporting a wheel is provided. The assembly includes a spindle defining a rotational axis and a support member for supporting the spindle. A wheel hub has a flange for securing the wheel thereto. The wheel hub is supported on the spindle and is rotatable about the rotational axis. A bearing assembly has first and second bearing members in spaced relationship from one another with a plurality of bearings interposed between the bearing members to permit relative rotation between the bearing members about the rotational axis. The first bearing member is arranged adjacent to the spindle and the second bearing member is arranged adjacent to either the wheel hub or the support member. An inner surface of the first bearing member has an annular counterbore. The spindle is deformed into the counterbore to axially secure the first bearing member to the spindle and prevent relative rotation between the spindle and the first bearing member about the rotational axis.

  • Patent number: 6575535
    Abstract: A wheel spindle flange (and the like) has stud holes with soft surface hardness formed therein which permit non-rotational splines, studs and the like to be press-fitted therein with minimal press force at a centered press zone established between intentionally formed and dimensioned counterbores within the flange to minimize flange distortion and lateral run out of the spindle.
