Abstract:
A linear gate drive assembly with a drive rail connectable to a gate panel. A linear drive portion having a toothed drive surface is coupled to a first drive surface of the drive rail and has teeth thereon with a first rolling tooth profile. A drive wheel is attached to one drive motor and engages the first drive surface to impart an axial drive force on the drive rail. Another drive wheel is attached to another drive motor and engages the second drive surface. The second drive wheel has teeth that mate with the first teeth and that define another rolling tooth profile corresponding to the first rolling tooth profile. Rotation of the second drive wheel imparts axial and normal forces via a rolling teeth interface for moving the drive rail and the gate panel.
