  • Rotary joint constant velocity stabilizer
    Patent number: 10156264
    Abstract: A rotary joint constant velocity stabilizer for connecting a first rotatable body and a second rotatable body, the first and second rotatable bodies being rotatable about a generally common axis of rotation and rotatable at substantially similar angular velocities. The rotary joint constant velocity stabilizer has a first base, a second base, and a shaft. The shaft is connected to first base such that the shaft is pivotable relative to the first base about a first axis extending from a first side to a second side of the first base. The shaft is connected to the second base such that the shaft is pivotable about a second axis extending from a first side to a second side of the second base, the shaft being slidable relative to the second base along a third axis normal to the first axis and the second axis, and rotatable relative to the second base about the third axis while preventing relative rotational motion between the first base and the second base.
