TUBE PROTECTIVE GEAR OF A POWER TRANSMISSION CABLE, CAPABLE OF EXTENDING A TUBE LIFE BY PREVENTING AN INNER CIRCUMFERENCE OF THE TUBE FROM DAMAGE

摘要

PURPOSE: A tube protective gear of a power transmission cable is provided to extend a power transmission length for a vehicle and instruments by increasing efficiency of power transmission due to a lower frictional coefficient while a flexible shaft contacts and rotates with bearing.;CONSTITUTION: A tube protective gear of a power transmission cable comprises: a tube(2) wherein a flexible shaft(1) is installed; a bearing(101) which is combined with an interior of the tube and is an oilless bearing; and a sleeve(102) which keeps distances between bearings and maintains flexibility of the tube.;COPYRIGHT KIPO 2010
