V-BELT FOR HIGH-LOAD TRANSMISSION

摘要

Disclosed is a V-belt for high load transmission, having multiple blocks (20) which are disposed on a tension belt (10) that extends in the longitudinal direction of the belt, and which are disposed such that each block (20) sandwiches an engagement area (18) of the tension belt (10) at a beam gap part (26) between upper and lower beam parts (23), (24), with said blocks being latched in place on said tension belt (10). The amount of increase (?T) due to thermal expansion of the measurement (T) in the belt thickness direction of the engagement area (18) of the tension belt (10) is less than or equal to the amount of change (?G) of the measurement (G) in the belt thickness direction of the beam gap part (26) of each block (20) in response to the driving of the belt (?T ? ?G).
