摘要： The invention relates to a method of production for attachment by cohesive bonding of a profile having at least one profile element onto a toothed belt previously produced as a semi-finished product. The toothed belt has a tooth side with a toothing and a toothed belt back located on the back of the tooth side of the toothed belt. In the method of production the at least one profile element is built up layer by layer from at least one first profile element layer and a second profile element layer on the toothed belt back, by the application of an application compound to the toothed belt back at a profile element position by melt layer printing.

摘要： A belt and sprocket system comprising a tensile cord disposed within a belt body, at least two teeth projecting from the belt body, the belt comprising a pitch length measured between the at least two teeth on the belt, one of the at least two teeth having a tooth tip and a profile comprising a first radius and a second radius and a third radius disposed between a first linear segment and a second linear segment, the sprocket having a groove for receiving one of the at least two teeth, the groove profile comprising a first radius and a second radius and the third radius and a fourth radius, each of which is connected in series to the others and each of which is unequal in length to the other radii, the tooth having a width that is approximately 35% of a pitch length at 90% of a tooth height so as to result in an interference fit between the one of at least two teeth and groove at 90% of the tooth height; and a volume between the tooth tip and the groove.

摘要： Toothed belt drive having one toothed belt and at least two, preferably helically geared, toothed pulleys, wherein the toothed belt wraps the toothed pulleys over a part-region of the circumference of the latter and the teeth of the toothed belt mesh in the tooth gaps of the toothed pulleys, wherein the air gap ES or ES(mk) that relates to the nominal pitch P and results from the difference between the width es of the tooth gaps of the respective toothed pulley and the width eR of the teeth of the toothed belt is configured at the mean height of the teeth, depending on the tooth count zR of the toothed pulleys and on the tooth count z of the toothed pulleys, or on the tooth counts zk of the smaller toothed pulley and on zg of the larger toothed pulley, respectively.

摘要： The object of the invention is a belt-type traction means, which comprises a herringbone toothed belt, which has at least a tooth part and a support structure supporting the tooth part, which support structure comprises a plurality of reinforcement means in the longitudinal direction of the toothed belt. In the transverse direction of the toothed belt the toothed belt comprises two edge parts side by side and a center part between the edge parts connecting the edge parts, the spring constant of which center part in the transverse direction of the toothed belt is smaller than the corresponding spring constant of the edge parts. In addition, the object of the invention is a method for fabricating the aforementioned traction means and the use of the traction means in an elevator as well as an elevator provided with the aforementioned traction means.

摘要： A drive belt having a main body formed of an elastomeric material, preferably a v-belt or v-ribbed belt, the drive belt including a top layer as belt backing, a power transmission zone having two or more tensile strands as strength members, and also a substructure optionally provided with some profiling preferably having a v-shape or a v-rib profile. The strength members are formed of cords made of mutually twisted plies (final twist), the plies being in turn twisted out of individual yarns (first twist). The cords consist essentially of polyethylene terephthalate (PET) and of two plies, the number of turns introduced into the plies twisted into a cord (final twist) and the number of turns introduced into the yarns twisted into a ply (first twist) differing by not more than 10 turns per meter (t/m).
