Rotary

 

_______________________________________

•  As it rolls, all surfaces scroll in the same direction at exactly the same surface speed

    .... there is no source of friction, so no lubrication is needed.


•  The minor effect of rolling-friction still exists,

    but the slipping, sliding and rubbing that exists in prior mechanics is eliminated,

    resulting in friction so low that lubrication is not needed.


•  Finally, totally lube-free rotary mechanics is a practical reality.

1. Center roller turns with counter rotating orbit rollers.

. . . . parts move WITH each other,
rather than rub AGAINST each other.
