METHOD FOR RECOGNIZING WEAR STATE OF CONVEYOR BELT

WIPO Patent Application WO/2017/051566

A1

Provided is a method for recognizing the wear state of a conveyor belt which makes it possible to recognize the wear state of a top cover rubber at the site of usage with high precision on the basis of a result of a wear resistance evaluation test using a sample. The relationship between the surface roughness R of a sample S and an apparent compressive stress Pe in a wear resistance test, and the relationship between the surface roughness R and the abrasion loss K1 per unit frictional energy of the sample S are acquired, and the wear state of the top cover rubber 3 is recognized on the basis of a database D1 created on the basis of these acquired relationships and an apparent compressive stress Pr generated in the top cover rubber 3 at the site of usage. Alternatively, the relationship between an average abrasion pitch P calculated from the surface roughness R and the viscoelastic property Re of the sample S, and the relationship between the average abrasion pitch P and the actual abrasion loss Vr of the sample S are acquired, and the wear state of the top cover rubber 3 is recognized on the basis of a database D2 created on the basis of these acquired relationships and the viscoelastic property Rr of the top cover rubber 3 at the site of usage.
