Description

  The present invention relates to a wear measurement gauge for measuring the wear amount of a V-ribbed belt.

  In an automobile engine, a V-ribbed belt having a plurality of V-shaped ribs extending in the belt circumferential direction is often used as a transmission belt used for driving an auxiliary machine such as an air compressor or an alternator. In the V-ribbed belt, both side surfaces of the V-shaped rib portion (groove portion) (the surface of the compression layer forming the rib portion) serve as friction transmission surfaces and transmit power by contacting and friction with the pulley surface. As the belt travels, the V-rib portion wears, but if the wear progresses and the V-rib portion (compressed layer) becomes thin, the life will eventually be reached and the belt needs to be replaced. Such confirmation of the progress of wear and determination of the life due to wear are difficult to visually confirm like the crack life. For this reason, a gauge for determining the belt wear state has been proposed as a method for detecting the life as a guide for belt replacement.

  With conventional gauges, belt wear is measured by sinking in the thickness direction of the belt, and since the rib part (groove part) is not visible, it is difficult to align with the rib part and it can be seen whether it is securely fitted Problems that cannot be measured (the amount of wear) cannot be measured (not visually confirmed) simply by checking the difference from the new rib shape (wear of the ribs) with a hand feeling (shaking or sinking). There is. Further, even if the gauge is rattled, it is difficult to handle and lacks accuracy because it is unclear whether the position of the fitting with the rib (groove) is misaligned or the wear is uneven.

The second member 3 has a long hole 3b into which the protruding portion 2a of the first member 2 is fitted. The long hole 3b has a restriction hole 3ba and a large-diameter hole 3bb formed at the left end of the restriction hole 3ba. The width in the height direction of the restriction hole 3ba is substantially the same as the width in the height direction of the protruding base portion 2ba of the first member 2. The size of the large diameter hole 3bb is larger than the size of the protruding tip 2bb.

  Accordingly, after the protruding tip 2bb of the protruding portion 2b of the first member 2 is disposed inside the large-diameter hole 3bb of the elongated hole 3b of the second member 3, the protruding base 2ba of the first member 2 is replaced with the second member.

And a slide part is slid with a finger | toe and a slide is stopped in the position where a groove part and a gauge fit. Remove the gauge that has been slid from the belt and read the slide amount. This measurement operation can be easily performed with one hand.

  FIG. 4A shows a state in which the first protrusion 2a and the second protrusion 3a of the wear measurement gauge 1 are respectively disposed in the groove portions of the V-ribbed belt that is not worn, and FIG. The first protrusion 2a and the second protrusion 3a of the measurement gauge 1 are shown in a state where they are respectively disposed in the groove portions of the worn V-ribbed belt. In FIG. 4A, the shape of the plurality of first protrusions 2a and the shape of the plurality of second protrusions 3a are the same as the shapes of the plurality of grooves of the V-ribbed belt in a state where the first protrusions 2a are not worn. 2a and the second protrusion 3a are not displaced in the width direction of the V-ribbed belt. On the other hand, in FIG. 4B, since the groove portion of the V-ribbed belt is worn, the second member 3 slides with respect to the first member 2 in the width direction of the V-ribbed belt, and the first protrusion 2a and the first protrusion 2a. The two protrusions 3a are displaced in the width direction of the V-ribbed belt. FIG. 4B shows a case where the second member 3 is slid by a predetermined amount with respect to the first member 2 (the first member 2 and the second member 3 are displaced from each other by a predetermined amount). The left end of the surface of the first color of the first member 2 protrudes by a predetermined amount to the left of the left end of the second member 3, and the second protrusion 3a of the second member 3 The first protrusion 2a of the first member 2 is shifted to the left by a predetermined amount, and the third color of the surface of the first member 2 is displayed from the opening 3c of the second member 3.
