摘要： A belt with a tensile cord embedded in an elastomeric body, having an adhesive composition impregnating the cord and coating the fibers. The adhesive composition is the reaction product of a polyisocyanate and a polyol, or a polyurethane prepolymer derived therefrom, and a polyamine curative and optionally additional polyol, and with optionally added plasticizer. At least one of the polyisocyanate, the prepolymer, and the polyamine are blocked with a blocking agent. The belt body may be of cast polyurethane, vulcanized rubber, or thermoplastic elastomer. The cord may have an adhesive overcoat.

摘要： The present invention relates to a toothed belt (1) having a belt body (10) which extends substantially in a longitudinal direction (X) and which comprises a flexible material, wherein at least one tension member (13), preferably a plurality of tension members (13), is at least substantially embedded in the flexible material of the belt body (10) in the longitudinal direction (X) and is at least substantially enclosed by the flexible material of the belt body (10), wherein the belt body (10) has a toothed side (11) with teeth (14) and tooth spaces (15) which alternate in the longitudinal direction (X). The toothed belt (1) is characterized in that a minimum thickness (a) of the flexible material of the belt body (10) in the vertical direction (Z) on the tension member (13) of at least one tooth space (15), preferably of all tooth spaces (15), corresponds at least to a minimum thickness (h) of the flexible material of the belt body (10) in the vertical direction (Z) on the tension member (13), wherein the minimum thickness (h) is calculated as follows in dependence on the thickness (d) of the tension member (13) in the vertical direction (Z) and on the material hardness (ShA) of the flexible material of the belt body (10) in Shore A: h=3*d/ShA.

摘要： A rubber-reinforcing cord (12) of the present invention includes at least three strands. Each of the strands includes at least one filament bundle and a first coating provided to cover at least a portion of the surface of the filament bundle. The filament bundle consists essentially of aramid fiber filaments. The mass of the first coating is in the range of 14 to 25% with respect to the mass of the filament bundle. Each of the strands is given primary twists at a primary twisting rate of 50 to 100 twists/m. The at least three strands each given primary twists are assembled and given final twists at a final twisting rate of 120 to 200 twists/m.

摘要： An apparatus for raising and lowering a cutting tool within a decoking drum, a decoking system and a method of raising and lowering a decoking system cutting tool. Instead of using metallic ropes, chains, or a self-propelled gear-based approach, non-metallic belts are secured at respective ends to a crosshead and one or more counterweights to enable vertical movement of the crosshead that in turn permits vertical movement of the cutting tool throughout the height of the drum. A motorized pulley system controls the movement of the belt, and preferably avoids having the motor be carried by the crosshead. The belts on each pulley are preferably arranged as cooperative sets so that within each set, both primary load belts and secondary load belts are present. Enhanced engagement between at least the primary load belts and the pulleys promotes greater load-bearing capability, while the secondary load belts are sufficiently strong to ensure positional stability of the crosshead and decoking tool upon damage to or failure of one or more of the primary load belts.

摘要： A power transmission belt at least includes a bottom rubber layer. A rubber composition for forming the bottom rubber layer contains a rubber component, cellulose fine fibers, and short fibers. The cellulose fine fibers have an average diameter from 1 nm to 200 nm, and the rubber composition contains 0.5 parts by mass or more of the cellulose fine fibers relative to 100 parts by mass of the rubber component. The short fibers have an average diameter from 5 μm to 30 μm, and the rubber composition contains 1 part by mass or more of the short fibers relative to 100 parts by mass the rubber component.
