A center cord-line V-belt with a radially centered cord line of helically wound tensile cord embedded in a very high-modulus adhesion gum, an overcord layer, and an undercord layer. The adhesion gum has a substantially isotropic modulus, while the overcord and undercord layers have anisotropy in with-grain and cross-grain moduli. The overcord and undercord cross-grain moduli are less than the adhesion gum modulus. The anisotropic moduli are the result of oriented short fibers and the with-grain modulus is oriented axially in the belt. The adhesion gum preferably has no short fiber. The belt preferably has no reinforcing fabric layer and no fabric wrap. The adhesion gum, overcord layer and undercord layer are preferably based on an ethylene-alpha-olefin elastomer, with peroxide cure, reinforcing filler, and metal salt of an α-β-unsaturated organic acid. The belt may have notches on one or both of the inner and outer radial surfaces for additional flexibility.

Center cord-line V-belt

A banded frictional power transmission belt with a satin-weave, band fabric wrapped around the outside of the belt. The band fabric may be a satin weave of warp and weft yarns and may include a high-strength, wear-resistant yarn such as aramid fibers, and may include a high-adhesive yarn such as nylon and/or cotton. The aramid and/or nylon fibers may be staple or filament fibers. The band fabric may be treated. The band fabric may have a 4&#xd7;1 satin weave. The band fabric may be wrapped on a bias. The high-adhesive yarn may predominantly reside on the inside of the fabric contacting said V-belt, and the high-strength, wear-resistant yarn may predominantly reside on the outside of the fabric which is the outer, pulley-contacting surface of the belt. The banded belt may be a V-belt, round belt, dual-V-belt, or multiple V-belts, or have another friction belt profile.

Systems and methods are provided for the improvement of an image of a device under test, such as a belt. The image of device under test is made more optimal by determining if the object is rotated away from a preferred axis of the image frame. If so, the image is rotated an opposing angle such that the object is parallel to the preferred axis of the image frame. The rotated image is then made available for analysis of the object. Rib width analysis is performed along the entire length of the detected rib by either de-rotating the image or not.

Enhanced analysis for image-based serpentine belt wear evaluation

A rubber composition having a reinforcing filler of activated carbon having a pore volume of 0.15 cc/g or more, a weight average particle size of less than 140 microns, and a differential characteristic curve of pore volume versus adsorption potential by the GAED or equivalent method having a peak value at less than 5 cal/cc. The rubber composition may have activated carbon as the primary reinforcing filler at a loading of from 25 to 250 phr. Also described is a method including the steps of selecting a charcoal material, grinding the charcoal material, activating the charcoal material, and mixing the activated carbon into a rubber composition as the primary reinforcing filler.

Tools for determining belt wear are provided. Specifically, non-contact based systems and processes are described which enable a quick and accurate measurement of belt wear. Based on the measurements of belt wear, a wear condition for the belt can be determined. Information regarding the wear condition can then be used to determine an appropriate remedial measure for responding to the determined wear condition.

Measurement of belt wear through edge detection of a raster image

A belt and method of marking a belt. A layer of polyethylene material is joined or cured to a belt. The layer is optically distinguishable from a belt body. The layer is etched to expose a portion of the belt body in order to contrast the layer with the belt body. A second layer of polyethylene material may be applied adjacent to the first layer. The second layer is optically distinguishable from the first layer. The first or second layer is etched using cutting, grinding or laser light in order to expose portions of the adjacent layer, or of the belt body, thus providing a method of permanently marking the belt.

Belt and method of marking

A belt having a region comprising a non-woven material region on a pulley engaging surface. The non-woven region is infused with an elastomeric compound. A predetermined amount of metal salt of carboxylic acid is included in the elastomeric compound during compounding. The metal salts of carboxylic acid significantly reduce or eliminate slip noise.

Power transmission belt

A low modulus power transmission belt having a multi-unit cord tensile member. The belt also comprises a low modulus elastomeric body. A multi-unit cord tensile member configuration is plied into the elastomeric body, the tensile cord members having an included angle in the range of 120&deg; to 180&deg; between each ply. The belt having an elastic modulus of less than 1,500 N/mm and having an elongation of approximately 6.8% over a load range of approximately 0-350 newtons.

A method of making a power transmission belt with discontinuous fibers by forming oppositely facing friction driving surfaces by grinding such that fiber protrudes from the driving surfaces and is bent exposing lateral side portions of fiber.
