FRICTION TRANSMISSION BELT, METHOD OF MANUFACTURING THE SAME, AND BELT TRANSMISSION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To suppress stick-slip noise while maintaining heat-resistant running performance of a friction transmission belt.;SOLUTION: The friction transmission belt B is provided with a compression rubber layer 11, on the inside of a belt body 10, that contacts a pulley and transmits power. The compression rubber layer 11 comprises: a surface rubber layer 16 formed from a rubber composition that has a relatively high plasticizer content; and an inner rubber layer 17, provided further towards the interior of the belt than the surface rubber layer 16 is, formed from a rubber composition that has a relatively low plasticizer content or does not contain a plasticizer.;COPYRIGHT: (C)2011,JPO&INPIT
