METHOD FOR DETECTING ABNORMALITY OF FLEXIBLE-BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for widely detecting an abnormality of a flexible-body for surely detecting an abnormality in the flexible body and avoiding a trouble occurring directly after operation of a transmission to inhibit disturbance in production process, decrease in manufacturing efficiency, and danger accompanying breakage and scattering of a belt regardless of the presence or absence of reinforcing wire rods.;SOLUTION: In the method for detecting an abnormality of a flexible-body, on the basis of the relative relationship between a deflection (δ) of the belt 4 in the belt transmission mechanism 1 and a tension (F) associated therewith, the deflection (δ) and the tension (F) are distinguished in two ranges, that is, a normal range A where the transmission mechanism 1 can perform a normal operation in the relationship between the deflection (δ) and the tension (F), and abnormal ranges B, C where the normal operation is hindered. The two distinguished ranges are stored beforehand in a memory. When at least either one of the deflection (δ) detected by a deflection detector 7, and the tension (F) detected by a tension detector 10 is determined to be in the category of the abnormal ranges B, C stored in the memory 11, the belt 4 is recognized to be abnormal.;COPYRIGHT: (C)2008,JPO&INPIT
