V-SHAPED BELT FOR HIGH LOAD TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To enhance heat radiation of a V-shaped belt for high load transmission.SOLUTION: In a belt C for high load transmission, a plurality of blocks 20 is locked to an endless tension band 10. In each block 20, a portion constituting both side surfaces in a belt width direction to be a pulley contact surface is formed with a resin composition in which powdery boron nitride is contained so as to be dispersed into a matrix resin and a fiber reinforcement material is contained by 15 mass% or more.
