Anti-reverse rotation apparatuses, rotors for use therein, and related methods

An anti-reverse rotation apparatus comprising:

• a stator defining:
• an interior volume;
• and
• one or more arcuate contact surfaces within the interior volume;
• and
• a rotor rotatably coupled to the stator and at least partially disposed within the interior volume, the rotor comprising:
• a hub;
• and
• two or more shoes, each pivotally coupled to the hub and extending between a first end and a second end that is farther from the hub than is the first end;
• wherein each of the shoes is rotatable relative to the hub between a first position in which the second end of the shoe contacts at least one of the arcuate contact surface(s) of the stator and a second position in which the second end of the shoe does not contact the arcuate contact surface(s) of the stator;
• and
• wherein the hub includes two or more first stops, and each of the shoes contacts a respective one of the first stops when the shoe is in the first position;
• wherein, when each of the shoes is in the first position, the shoes restrict rotation of the rotor relative to the stator in a first direction through contact with the arcuate contact surface(s) of the stator and the first stops of the hub;
• and
• wherein rotation of the rotor relative to the stator in a second direction that is opposite to the first direction urges each of the shoes toward the second position.

A method comprising:

• rotating a rotor relative to and within a stator, the rotor having:
• a hub including two or more first stops;
• and
• two or more shoes, each pivotally coupled to the hub and extending between a first end and a second end that is farther from the hub than is the first end;
• wherein the rotating is performed such that each of the shoes rotates relative to the hub:
• from a first position in which the shoe is in contact with at least a portion of a respective one of the first stops and the second end of the shoe is in contact with the stator;
• and
• toward a second position in which the shoe does not contact the portion of the respective first stop and the second end of the shoe does not contact the stator.
