<p>The present invention relates to a thermo-sensitive variable pulley and, specifically, to a thermo-sensitive variable pulley which can maintain a rotational speed to be almost at a certain value or less by frictional heat caused by slips. The thermo-sensitive variable pulley, according to the present invention, comprises: a disk-shaped driving rotation unit of which one side is coupled to a driving motor and the other side has a first contact surface formed thereon so as to rotate; a driven rotation unit of which one side has a second contact surface coming in surface contact with the first contact surface, has a belt coupled around the outer circumference thereof, and rotates while the second contact surface comes in surface contact with the first contact surface; and a contact variable unit for adjusting the adhesion between the first contact surface and the second contact surface by frictional heat which is caused by slips of the first contact surface and the second contact surface according to a rotational speed difference between the driving rotation unit and the driven rotation unit.</p> |
