Methods and apparatus to reduce noise in motor assemblies

An apparatus to reduce noise in a motor assembly, the apparatus comprising:

• a drive coupling structured to couple a motor with a covering such that rotation of a motor drive shaft of the motor causes movement of the covering, wherein the drive coupling comprises:
• a driver connected to the motor drive shaft such that the rotation of the motor drive shaft causes rotation of the driver about a first axis, and
• a vibration absorber connected to the driver and coupling the driver with the covering, wherein:
• the vibration absorber defines a groove circumferentially extending around an edge of the vibration absorber;
• and
• the groove is defined concentric about a second axis parallel to the first axis;
• and
• a tube adapter that comprises a body and a plurality of arms extending from the body, wherein:
• the plurality of arms defines a notch concentric about the second axis;
• and
• the vibration absorber is received in the notch.

A method comprising:

• positioning a drive coupling relative to a motor;
• positioning the drive coupling relative to a covering, wherein the drive coupling is structured to couple the motor with the covering such that rotation of a motor drive shaft of the motor causes movement of the covering, wherein the drive coupling comprises:
• a driver connected to the motor drive shaft such that the rotation of the motor drive shaft causes rotation of the driver about a first axis, and
• a vibration absorber connected to the driver concentric about a second axis offset from, and parallel to, the first axis and coupling the driver with the covering, such that rotation of the driver causes the movement of the covering based on the coupling that is provided by the vibration absorber;
• and
• positioning a tube adapter relative to the drive coupling, wherein:
• the tube adapter includes a body and a plurality of arms extending from the body;
• the plurality of arms defines a notch concentric about the second axis;
• and
• the vibration absorbent is received in the notch.
