BACKLASH-FREE CABLE TRANSMISSION DEVICE

摘要

PURPOSE: A backlash prevention cable power transmission device is provided to transfer power by moving a first driving pulley to an opposite direction with a traveling direction of a contact point of a pulley part about a cable. CONSTITUTION: A motor part(60) offers torque. A pulley part is connected with the motor part and is rotated. A cable(20) is wound on the pulley part. A motor is installed to a first fixing frame and has a rotary shaft. A driving shaft(62) is connected with the rotary shaft of the motor and is rotated. A first driving pulley is installed to be possible to slide to an axial direction. A second driving pulley is connected with the first driving pulley and is rotated. The first driving pulley and the second driving pulley have a same external diameter.
