  • Patent number: 11761517
    Abstract: A drive system comprising a rotatable input disc that receives an input rotational force and rotates about a longitudinal axis, where the input disc comprises driving features formed on its interior face. The drive system also comprises a rotatable output disc that rotates about the longitudinal axis and comprises driving features formed on its interior face, where the output disc provides an output rotational force. The drive system comprises a drive core between the interior face of the input disc and the interior face of the output disc to translate the input rotational force to the output rotational force. As the input disc is rotated by the input rotational force, engaging feature(s) of power disc(s) in the drive core engages the driving features of the input disc causing rotation of each power disc. As the power disc(s) is rotated, the engaging feature(s) of each power disc(s) engages the driving features of the output disc causing rotation of the output disc.

  • Patent number: 11761851
    Abstract: A drive system includes a motor having a rotatable output shaft that is operably coupled to a lead screw by a transmission that converts rotary output of the motor into linear translation of the lead screw. The drive system further includes a position sensor configured to sense a position of the lead screw. A method for determining a backlash of the drive system includes the steps of sensing an initial position and driving the lead screw in a first direction to a calculated second position by controlling the motor to rotate the output shaft an amount that corresponds to a distance between the initial position and the calculated second position. The method further includes the steps of sensing an actual second position of the lead screw; and determining a backlash value according to a difference between the calculated second position and the actual second position.
