TORQUE TRANSMISSION SYSTEM FOR HELICAL DRILLING TOOLS

摘要

The application refers to equipment for soil engineering, to a system that makes easy the procedures of soil drilling by helical tools, increasing the performance of the machines, speeding up its operation and improving its performance, being based on the introduction of notches (2) in the blades of the helix (3), disposed to 120th degrees one of the other ones and aligned along the helix (3) for insert in cotters (4), diametrically disposed in a central axis (5) inside the rotator (6) through gearing (7, 8), powered by electric or hydraulic motor; being still, the notches (2) are aligned consisting on one, two or more rows, as it is necessary to resist to the torque of the rotator.
