Abstract
A variable valve timing assembly includes an electric motor; a first set of gears driven by the electric motor; a first set of grooves and ball bearings driven by the first set of gears; a second set of grooves and ball bearings driven by the first of grooves and ball bearings; wherein the first set of grooves and ball bearings converts rotational movement of the first set of gears to axial rotational movement of the first set of ball bearings; wherein the axial movement of the first set of ball bearings causes rotational movement of the second set of grooves; whereby the rotational movement of the second set of grooves enables rotation of a camshaft engaged to a valve.

A variable valve timing assembly, comprises:
- an electric motor;
- a first set of gears driven by the electric motor;
- a first set of grooves and ball bearings driven by the first set of gears;
- a timing helix having a timing helix cylindrical body, a timing helix bottom wall from which the timing helix cylindrical body extends, and a second set of grooves;
- a timing gear having a timing gear cylindrical body and a second set of ball bearings disposed in the second set of grooves of the timing helix;
- wherein the timing helix bottom wall is configured to abut a camshaft therethrough;
- wherein the second set of grooves and ball bearings are driven by the first set of grooves and ball bearings;
- wherein the first set of grooves and ball bearings converts rotational movement of the first set of gears to axial movement of the first set of ball bearings;
- wherein the axial movement of the first set of ball bearings causes rotational movement of the second set of grooves;
- whereby the rotational movement of the second set of grooves enables rotation of the camshaft engaged to a valve.
