      @ameraldas3641 3 года назад +2

      I would say that the one thing that I could see being made simpler is, to make the sphereacle gear on a CNC 5 axis mill, or to make it in such a way that you have 3 sets of gears cast them and a few thousands too big and have them run together to give them a perfect fit as well as work hardening them at the same time. ( i may be wrong about this )
      But the design is already very simple, once proven economically viable for some there will be alot of patent avoiding, or patent disregarding chinese knockoffs that are more complex.

    I had something completely different in mind when I saw the title - basically 2 spherical burrs with their grooves meshing. This would allow one gear to be tilted off axis and, providing the contact is maintained at the same "latitude" on both burrs (requiring a slightly complicated hinge mechanism),, the rotational speed would be unchanged as they tilted. Chaining these together would allow torque to be transmitted from one end of a flexible chain to the other without the friction loss or binding due to buckling of a cable in sheathe.

      @@Inertia888 Worm gears are fairly simple to understand, think of them as a screw rather than the typical gear. A rotation of a screw will progress the teeth linearly by a certain distance. In actual screws, you can see this being done by the screw progressing into a material. But in this instance, you need to reverse which part is moving, here the screw remains stationary in space while the complimentary piece moves; and that complimentary piece is a gear that rotates on an offset, perpendicular axis.
      You can also think of it as a rack in pinion, where a rack would move linearly to rotate the pinion. Except this doesn't have the space for a linear rack, so you take the 2D profile of a rack and wrap it around an axes where one revolution aligns with the next tooth on the rack, thus creating a screw that can be rotated to rotate the pinion through rotation of the screw.
      Of course this is an extremely simplified explanation of worm gears, some worms do have much more complex designs than this. There's countless videos on explanations and animations on the internet if you still don't understand them.

      This isn't just an actuated ball joint, it is a true 3dof actuated ball joint. Linkages limit your range of motion and require rotational limits. With the exception of the socket limitations, this has none of that.

      @@pstrap1311 everything mentioned above for sure. However maybe a non-traditional use would be digging through soft soils. Having sharp points like that and being able to rotate them in any direction would aid in cutting through the soil and then removing the soil. If rocks were encountered it would help steer the vehicle around the rocks. There's really any number of applications. My favorite application for this though would be Omni directional steering. There's this thing called a magnetic gear, if This were re-engineered to use that then this is the perfect omnidirectional wheel.

      I was wondering the same thing. But directly at pole it would be possible just to rotate the direction of the monopole gear, instead of pivoting it really fast. But this is only possible AT pole, not in the vicinity of the pole. I also wonder if mounting the motors opposite to each other instead of under an angle has influence on where the pole point is.

    interesting, though some comments on play and stiction would be required to assess the usefulness of the setup.
    e.g. towards instant 4'30" for instance, one can clearly see the lack os smoothness oof the motion, which is likely to result from non constant friction of a plasticly constraint setup in order to reduce play.
    then there is the difficulty of the computational inverse geometry with poles...
