Abstract
A continuously variable helical transmission system comprising a frame, a central drive shaft configured to rotate about its longitudinal axis within the frame, and at least one angular wheel rotatably attached to the frame and configured to pivot about an axis being radial to the frame, wherein a longitudinal translation of the central drive shaft rotates the at least one angular wheel about the radial axis.
Claims20
A continuously variable helical transmission system comprising:
- a first frame;
- a central drive shaft configured to rotate about its longitudinal axis within the first frame;
- and
- a set of rotatable angled wheels attached to the first frame, each of the wheels being configured to pivot about an axis being radial to the first frame;
- wherein one or more of the wheels rotatably engages a bushing assembly configured to rotate about the central drive shaft;
- wherein a rotation of the central drive shaft causes the rotation of the wheels about their radial axis which results in a longitudinal translation of the first frame.
3 more elements
A method of varying the translation velocity of a helical drive system, the method comprising:
- rotating a central drive shaft to cause the rotation of the wheels about their radial axis resulting in a longitudinal translation of the first frame;
- engaging a helical groove of a bushing assembly to rotate the bushing assembly about a longitudinal axis of the central drive shaft;
- rotating a set of rotatable angled wheels attached to the frame about an axis being radial to the longitudinal axis of the central drive shaft.
