摘要： A method for estimating remaining life of a power transmission belt. The method includes a step of providing a power transmission belt having a) a body having a rubber material with a length and laterally spaced surfaces to engage a cooperating pulley and b) a plurality of fibers embedded in the rubber material and projecting in a lateral direction so that a plurality of the fibers have a portion that is exposed at one of the laterally spaced surfaces. The method further includes the step of magnifying the one laterally spaced surface to identify cracks in the rubber at the fiber portion. Based on at least one of the nature and quantity of cracks in the rubber material, the remaining life of the power transmission belt is estimated.

摘要： A multiribbed power transmission belt and method of manufacturing the same, wherein an unvulcanized belt preform is provided with transversely extending staple fibers in the compression section thereof. The compression section is caused to be vulcanized while being urged against a mold having projections forming shallow grooves in the inner surface thereof. The grooves have a depth in the range of approximately 20% to 50% of the height of the ribs intended to be formed in the final power transmission belt. The ribs are formed in the belt by removing material from the compression section of the vulcanized preform, such as by the conventional machining operations of grinding, cutting, etc. The angular deflection of the reinforcing fibers in the compression section is caused to be no more than approximately 25% to provide the improved belt construction.

摘要： A power transmission belt having an endless body with a length, an inside, and an outside. The body has cogs on at least one of the inside and outside of the body and spaced along the length of the body so as to define alternating cog crests and cog troughs. The cog crests each have oppositely facing side surfaces with an apex between the oppositely facing side surfaces. There is a reinforcing fabric on the at least one of the inside and outside of the body. The reinforcing fabric has first and second spaced end portions with a first free end at the first end portion and a second free end at the second end portion. The first and second end portions overlap so that the first and second free ends are each at a side surface on a cog crest.
