Abstract:
Die Erfindung bezieht sich auf ein treibfähiges Trag- bzw. Zugmittel und ein Verfahren zu dessen Herstellung, mit mindestens einer Lage von Litzen aus synthetischem Fasermaterial und mit einem die Litzen umhüllenden Aussenmantel, wobei in das Trag- bzw. Zugmittel ein Schmiermittel selektiv eingebracht wird, derart dass die Litzen für eine Relativbewegung gegeneinander mit einem Reibwert geschmiert sind.
Abstract:
A hoist for an elevator, wherein a rotating shaft (6) supported rotatably on bearing stands (2, 3) is rotated by a driving force of a drive motor (8) so as to move a car up and down through a main cable (7), a main cable application part (6a) for applying the main cable (7) thereto is formed integrally with the rotating shaft (6) and a plurality of rope grooves (6b) for inserting the main rope (7) therein are provided in the main rope application part (6a).
Abstract:
Le toron comporte un groupement de brins métalliques torsadés (2), une gaine en matière plastique (4) et un produit souple de remplissage (3) comblant des interstices internes situés entre les brins torsadés du groupement et un interstice périphérique situé entre la périphérie du groupement et la face intérieure de la gaine. Cet interstice périphérique présente, dans une section transversale du toron, une aire comprise entre P × e min et 0,6 × S2, où P est le périmètre extérieur du groupement de brins, e min = 0,05 mm et S2 est l'aire cumulée des interstices compris entre la périphérie du groupement et le plus petit cercle dans lequel s'inscrit le groupement.
Abstract:
Câble aramide à haute résistance en flexion comprenant une âme (1) autour de laquelle sont toronnés des fils synthétiques revêtus par une gaine (5). Selon l'invention, les fils synthétiques (2, 3, 4) sont des fils aramides imprégnés à coeur par une résine (8) à haute résistance à l'abrasion et à faible coefficient de frottement. Applications : Câbles de manutention devant subir un grand nombre de flexions alternées.
Abstract:
A composite wire (10) comprising an outer layer (1) and an inner por¬ tion (2, 3), said outer layer (1) being of linear or helical form and consisitng of a metallic material, and said inner portion comprising fibers (2) and/or pultruded bars (3), the fibers (2)and/or pultruded bars (3) being arranged parallel to the lon¬ gitudinal axis of the composite wire (10) or in a twisted manner. The composite wire (10) may be used autonomously or as part of strands (12) or ropes (13), The composite wire (10) has higher resis¬ tance to axial stresses, improved wear properties and reduced specif¬ ic weight compared to metal wires.

Abstract:
The present invention is to provide a hybrid core rope (1) which does not require maintenance or a hybrid core rope (1) capable of reducing a maintenance task. The hybrid core rope (1) includes a resin solid core (2) in which a plurality of spiral grooves (2a) is formed in the longitudinal direction on an outer peripheral surface thereof, a plurality of fiber bundles (3) respectively spirally wound around the outer peripheral surface of the resin solid core (2) along the plurality of spiral grooves (2a), the fiber bundles (3) having thickness to fill the spiral grooves (2a), and a plurality of steel strands (4) spirally wound around the outer peripheral surface of the resin solid core (2) around which the fiber bundles (3)are wound. The fiber bundles (3) and the strands (4) are respectively wound so as to have angles which are not parallel to each other.

Abstract:
In an elevator hoisting machine, a rotating shaft is rotatably supported in a bearing mount. The rotating shaft is rotated by a driving force from a drive motor. An elevator car is raised and lowered by means of a main rope by rotation of the rotating shaft. A main rope winding portion around which the main rope is wound is formed integrally on the rotating shaft. A rope groove into which the main rope is inserted is disposed on the main rope winding portion.
