芳纶橡胶输送带的接头强度研究

Study on Joint Strength of Aramid Reinforced Rubber Conveyor Belt

采用指型插接方案,研究指型长径比、贴胶厚度和织物增强层结构等因素对芳纶橡胶输送带接头强度的影响。结果表明:接头强度随长径比的增大而提高;接头强度随贴胶厚度的增大而提高,在1 mm时达到最大值,此后随贴胶厚度的增大而下降;织物增强层沿经向放置的输送带接头强度可提高87%。

In this study,the effect of aspect ratio,thickness of rubber compound and structure of fabric reinforcement layer of the finger type joint on the joint strength of aramid reinforced rubber conveyor belt was investigated.The results showed that,as the aspect ratio increased,the joint strength increased.As the thickness of rubber compound increased,the joint strength increased at first and then decreased,and the maximum value was obtained when the thickness was 1 mm.Moreover,the joint strength increased by 87% when reinforcement fabric was placed in parallel direction of the belt.
