Cable Drive Linear Positioner

A linear positioning drive is disclosed having: low cost, high axial stiffness, zero backlash, high speed capability, high load capacity, long service lifespan, and low heat production. Cost reductions vs. prior art are most significant for drive lengths over one meter. A motor supporting carriage carries a drum sheave held perpendicular to the linear movement direction. Dual cables extend from the drum in parallel but opposite directions at the drum groove helix angle. Cable reeving with multiple dead wraps ensures retention of this cable to groove angular alignment, which in turn, supports long service lifespans for both cable and drum. Each drum rotation moves the dual cable-to-drum departure locations one drum groove pitch, and moves the carriage one groove helix wrap length. Both movements are linearly proportional to any extent of drum rotation. Cable to drum groove alignment is thus maintained over the full range of carriage movement.
