TOOTHED BELT
Document Type and Number:
WIPO Patent Application WO/2024/024435
Kind Code:
A1
Abstract:
A toothed belt according to the present invention comprises: a belt body that has a plurality of teeth that are provided to the inner circumference of the belt at a regular pitch; and core wire that is embedded in the belt body so as to have a pitch in the width direction of the belt. The peak friction coefficient μA and average friction coefficient μB as measured by the following method satisfy μA-μB≤0.3 and μB≤0.5. The toothed belt is cut in the width direction to obtain a measurement sample that is a two-tooth portion of the belt, a constant load is applied to the measurement sample while the tips of the teeth are in contact with an SUS304 plate, and the frictional force is measured when the measurement sample is moved for 30 sec in one direction at a speed of 100 mm/min, the friction coefficient calculated by dividing the maximum value of the frictional force for the 30 sec by the normal force being the peak friction coefficient μA, and the friction coefficient calculated by dividing the average value of the frictional force for the 30 sec by the normal force being the average friction coefficient μB.
