ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to coupling devices for rotational drive systems and more particularly to coupling devices for driving earth augers.
SUMMARY OF THE INVENTION
The present invention is directed to a polygonal ball drive system for use with a motor assembly to implant and withdraw an apparatus from the ground. The polygonal ball drive system comprises a drive member operatively connectable to the drive motor assembly, a drive ball member having an upper portion, a non-circular central portion and a lower portion, a drive socket member having a first end and a second end, and a drive socket locking assembly.
The first end of the drive socket member is connectable to the drive member and the second end comprises a tubular portion defining a drive ball receiving chamber for torque transmitting engagement with the central portion of the drive ball member. The lower portion of the drive ball member in turn is drivingly connectable to the apparatus. The drive socket locking assembly is adapted to releasably lock the drive socket member and the drive ball member in operative engagement. The upper and lower portions of the drive ball member are such that the diameters are smaller than the central portion so as to permit angular axial misalignment of the drive ball member within the drive socket member.
The present invention is further directed toward a polygonal ball drive system for use with a drive motor assembly and an apparatus. The polygonal ball drive system comprises a drive member operatively connectable to the drive motor assembly, a drive socket member having a first end and a second end, and a drive ball member having an upper portion, a noncircular central portion and a lower portion.
The first end of the drive socket member is connectable to the drive member, and the second end comprises a tubular portion defining a drive ball receiving chamber. The upper and central portions of the drive ball member are connectable in torque transmitting engagement with the drive ball receiving chamber and the lower portion is drivingly connectable to the apparatus. The upper and lower portions of the drive ball member are such that the diameters are smaller than the central portion so as to permit angular axial misalignment of the drive ball member within the drive socket member.
