Abstract
A series of inner fitted pipes with linear and helical guides or opposing helical guides for converting linear to rotational motion or converting rotational to linear motion of a support device. Hydraulics or electric screw drives are used to power the linear motion and then is converted to rotational adjustments of a directing or lifting support. This rotational support is capable of being used as a solar tracker, a robot, an exercise machine and a lift.
Claims15
A rotational support comprising:
- a stationary cylinder firming the sole base of said support;
- a rotational cylinder formed coaxial with said stationary cylinder about a first axis, the rotational cylinder axially abutting said stationary cylinder;
- retaining means for preventing axial movement of said rotational cylinder relative to said stationary cylinder, the retaining means functioning solely between the stationary and rotational cylinders without any additional support;
- an inner cylinder coaxial about the first axis, the inner cylinder extending axially between said stationary cylinder and said rotational cylinder, the inner cylinder engaging both the stationary and rotational cylinders;
- wherein said inner cylinder, stationary cylinder and rotational cylinder have cam grooves and cam followers between the inner cylinder and the stationary and rotational cylinders, so that axial motion of the inner cylinder results in rotational motion of the rotational cylinder.
