摘要:
A pulley belt (100) for transmitting force from a first pulley (12) to a second pulley (14) includes a belt member (110) having a contact surface (120) configured to be in contact with the first pulley (12) and the second pulley (14). A plurality of projections (122) extends from the contact surface (120). The projections have a predetermined height/diameter aspect ratio. In a method of making a pulley belt, an uncured elastomer (316) is placed in a mold (310) having a shape of a belt member (320) with an inner surface from which patterned projections (312) extend inwardly. The uncured elastomer is cured to form a cured belt member (320), which is removed from the mold (310).
摘要:
A hybrid chain belt which includes a toothed rubber belt and a pair of chains comprising a plurality of interleaved or laced sets of inner chain links and a plurality of interleaved outer or external links immediately adjacent the inner links mounted to the sides of the toothed belt. Each of the inner links and outer links has a pair of spaced apertures for receiving at least one pin which passes through the apertures of the links. The pins extend through the teeth of the rubber belt. Alternatively, the pair of chains may be replaced with outer links with either two apertures or a single aperture.

A splice is described for jointing thermoplastic strips that include steel cords. In the splice a splice polymer is used that is a mixture of a co-polymer and a base polymer, wherein the co-polymer is a grafted co-polymer, a block co-polymer or a random co-polymer functionalized for enabling adhesion to the steel cords. Particular about the inventive splice is that the amount of co-polymer in the base polymer is such that in a test-till-break of a splice, part of the steel cords fracture in the test while the remaining cords are pulled out of the polymer without breaking. Surprisingly, a splice with such a failure behavior results in a better overall splice strength than a splice wherein a too large amount of co-polymer is added. When too much co-polymer is added all steel cords break in the test which strangely enough leads to a lower overall strength of the splice.

The present invention relates to a transmission belt containing a core wire extending in a lengthwise direction of the belt, an adhesive rubber layer in contact with at least a part of the core wire, a back surface rubber layer formed on one surface of the adhesive rubber layer, and an inner surface rubber layer formed on the other surface of the adhesive rubber layer and engaging or in contact with a pulley, in which the adhesive rubber layer is formed by a vulcanized rubber composition containing a rubber component, a fatty acid amide and a silica.
摘要:
A method of manufacturing a rubber-metal composite, the method including a process of bringing a metal material into contact with a buffer solution having a pH of from 5 to 7.2, followed by a process of causing the metal material and rubber to adhere to each other.
摘要:
A conveyor belt of elastomeric material, especially natural and synthetic rubber material, with thread-shaped strength members extending in the longitudinal direction of the belt and being located in parallel spaced relationship to each other while being embedded in the elastomeric material of the belt, the strength members being in the form of wires united to each other by a single twist.

A V-ribbed belt in which a friction transmission surface of a compression rubber layer is coated with a knit fabric is provided. The compression rubber layer is formed of the cured product of a rubber composition containing an ethylene-α-olefin elastomer and carbon black wherein the carbon black contains a soft carbon having a primary particle diameter of at least 40 nm and a hard carbon having a primary particle diameter of less than 40 nm. The ratio between the number of particles of the soft carbon and hard carbon is former/latter=3/97 to 25/75.
摘要:
A belt for drive technology having a belt body made from two polymer materials (A) and (B) with elastic properties and including a top layer as the belt back and a substructure with a force transfer zone and a tension member embedded in the belt body. The first material (A) contains 15 to 50% w/w of at least one fire-resistant additive and is used everywhere in the belt body where high mechanical properties are not required and the second material (B) contains 5 to 35% w/w of at least one fire-resistant additive and is used in the are of the belt body that is subjected to the highest mechanical stresses. The belt is particularly used as a tractive element for hoisting technology.
