  • Publication number: 20030225545
    Abstract: A method, apparatus, and program for estimating noise generation for a synchronous belt having a length and teeth spaced along the belt length. The method includes the steps of: calculating belt displacement transversely to the belt length at or near a first location at which teeth on the belt mesh with teeth on a first cooperating toothed pulley; calculating a belt fluctuation velocity by correlating the belt displacement to a time frame; and calculating a radiated sound pressure level using the belt fluctuation velocity.

  • Patent number: 5007884
    Abstract: A power transmission belt having longitudinally spaced pairs of blocks on the opposite surfaces of a neutral belt portion thereof. The blocks are formed of hard synthetic resin materials having fibers distributed therein. The fibers may be provided in the form of distributed short fibers, fabrics, and one or more different types of fibers may be utilized in the respective blocks. The fibers include carbon fibers, aramid fibers, and silicon carbide fibers. The neutral belt is provided with longitudinally spaced projections on the upper and lower surfaces thereof and the blocks are provided with complementary recesses receiving the projections. The recesses are preferably deeper than the height of the projections, whereby the distal surfaces of the blocks may be urged with high frictional engagement against the flat surfaces of the neutral belt.

  • Patent number: 4852625
    Abstract: A tire for a two-wheeled vehicle, particularly, a bicycle intended for a racing purposes having an improved running stability, superior durability and impact resistance, and reduced weight. The tire includes a carcass layer formed by arranging cord belts with a rubber paste coated thereon in such a manner that the cords of the cord belts cross each other. A tube is fitted to the inside of the carcass layer, and a rubber tread portion is bonded to the outer periphery of the carcass layer. The cord belt is produced in bias form with alternately arranged cords superior in durability and impact resistance and cords superior in adhesion with rubber. The two types of cords may be equal in number, or a majority of one of the two types of cords employed, depending upon the precise application of the tire and the conditions under which it is intended for use.

  • Patent number: 4575445
    Abstract: A method of forming a long cogged power transmission belt including extending a continuous looped vulcanizable belt preform element about a pair of axially parallel spaced support members, press-forming a first preselected length portion of the element disposed between the support members to form a first longitudinally extending series of cogs therein, vulcanizing the press-formed portion, press-forming a second, similar length portion of the element extending from the first portion and disposed between the support members to form a second longitudinally extending series of cogs therein continuing from the first series, vulcanizing the second press-formed portion, repeating the press-forming and vulcanizing operations if necessary until a final unformed portion of the belt extending from the last formed series of cogs and disposed between the support members has a length less than the preselected length, longitudinally stretching the final unformed portion to cause it to have a length approximately equal to t
