  • Patent number: 7736062
    Abstract: For machinery comprising rotary components attached to at least one drive shaft, at least one rotary bearing to position the drive shaft with a rotational freedom of movement about a drive shaft axis and associated stationary components, apparatus that comprises: a rotary backup bearing sleeve attached to the drive shaft proximate the bearing comprising a rotary radial surface relative to the drive shaft axis and a rotary axial surface relative to the drive shaft axis; and a stationary backup bearing collar mounted to one of the stationary components proximate the rotary backup bearing sleeve comprising a stationary radial surface relative to the drive shaft axis proximate the rotary radial surface with a predetermined axial clearance and a stationary axial surface relative to the drive shaft axis proximate the rotary radial surface with a predetermined axial clearance.

  • Publication number: 20090074338
    Abstract: For machinery comprising rotary components attached to at least one drive shaft, at least one rotary bearing to position the drive shaft with a rotational freedom of movement about a drive shaft axis and associated stationary components with at least one predetermined clearance from the rotary components, apparatus to prevent the rotary components from contacting the stationary components upon failure of the bearing, comprises: a rotary backup bearing sleeve attached to the drive shaft proximate the bearing comprising a rotary radial surface relative to the drive shaft axis and a rotary axial surface relative to the drive shaft axis; and a stationary backup bearing collar mounted proximate the rotary backup bearing sleeve comprising a stationary radial surface relative to the drive shaft axis proximate the rotary radial surface with a predetermined axial clearance and a stationary axial surface relative to the drive shaft axis proximate the rotary radial surface with a predetermined axial clearance; wherein t
