Abstract
Rotor bearings are provided. The motor bearing can be used in an electric submersible pump motor. The bearing can include a body and one or more anti-rotation pins disposed partially in a groove in an outer surface of the body and configured to be received in a corresponding keyway in an inner diameter of a stator. The anti-rotation pin prevents or inhibits rotation of the bearing relative to the stator.
Claims23
A motor bearing comprising:
- a body;
- and
- an anti-rotation feature projecting radially outwardly from an outer surface of the body, the anti-rotation feature configured to be received in a corresponding keyway in an inner surface of a motor stator.
(canceled)
A motor bearing comprising:
- a body comprising a groove in an outer surface of the body and extending axially along a length of the body;
- an anti-rotation mechanism disposed partially in the groove and projecting radially outwardly from the outer surface of the body, the anti-rotation pin configured to be received in a corresponding keyway in an inner surface of a motor stator;
- and
- a centering mechanism disposed circumferentially about the outer surface of the body and configured to limit displacement of the motor bearing relative to the stator in use.
