ABSTRACT:
An apparatus for testing a power transmission belt is disclosed, wherein a test belt is mounted between a pair ot pulleys secured to first ends, respectively, of a pair of shafts disposed in parallel and a drive belt is mounted, through idlers, between another pair of pulleys respectively secured to the other ends of the shafts. One of the shafts is supported on a movable plate adapted to be moved in conformity with the length of the test belt. Pitch diameters of these pulleys are determined to exert torque on the shafts to thereby apply tension to the belts. The idlers are disposed so as to avoid displacement of the drive belt regardless of the length of the test belt, and one of the idlers is movably disposed to further control tension of the drive belt.
