Conveyor belt
A conveyor belt includes a core layer disposed between an upper cover rubber layer and a lower cover rubber layer. The core layer is configured from a plurality of steel cords covered by cushioning rubber and arranged in parallel. The rubber that forms the lower cover rubber layer is a low loss rubber that has a loss factor tanδ of 0.07 or less at a frequency of 10 Hz, 2% dynamic strain, and temperature of 20° C. The maximum thickness of the cushioning rubber is reduced to not more than ⅓ the nominal diameter of the steel cords.
1. A conveyor belt, comprising:
a core layer disposed between an upper cover rubber layer and a lower cover rubber layer, the core layer being configured from a plurality of steel cords covered by cushioning rubber and arranged in parallel;
a rubber that forms the lower cover rubber layer being a low loss rubber that has a loss factor tanδ of 0.07 or less at a frequency of 10 Hz, 2% dynamic strain, and a temperature of 20° C.; and
a maximum thickness of the cushioning rubber being not more than 1/3 a nominal diameter of the steel cords;
wherein adjacent steel cords of the core layer are linked by the cushioning rubber and a thickness of the cushioning rubber which covers outer circumferential surfaces of the steel cords is the same as a thickness of a cushioning rubber between adjacent steel cords.
2. The conveyor belt according to claim 1 , wherein a nominal diameter of the steel cords is from 2.5 mm to 12.0 mm.
