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.
Abstract:
A synthetic rope (1) for an elevator having improved resistance to compression and abrasion is provided and comprises a plurality of strands (7) forming layers of the rope, each strand formed from a plurality of pre-twisted strands (19) from high modulus synthetic filaments (21). One or more of the strands or layers of strands may be impregnated with a lubricant, such as polytetrafluoroethylene, to reduce the abrasion among the strands and substrands, and increase the service life of the rope. The exterior of the rope may be covered by a jacket (35) that provides for traction with the drive sheave. An elevator system comprising the claimed rope is also provided.
Abstract:
A wire rope (10, 20), comprising: a core (12, 22), a plurality of outer strands (18, 28) and a plurality of separator strands (17, 27) laid on said core (12, 22), and a first plastic jacket (19) around said plurality of outer strands (18, 19) and said plurality of separator strands (17, 27), wherein said plurality of separator strands (17, 27) extend from said core (12, 22) and in-between each pair of said plurality of outer strands (18, 28) so as to produce and maintain gaps between said pair of said plurality of outer strands (18, 28). Plastic impregnation of the wire rope (10, 20) can be ensured due to the separator strands/17, 27).
Abstract:
The invention relates to a traction rope (1) comprising a one-piece core (2) comprising a central kernel (4) provided on its periphery with a set of regularly spaced fins (5) that form between one another receiving grooves (6) having an at least partially circular section, and strands (3) disposed around the core (2) by insertion into each of the receiving grooves (6), such that the combination of the core and the strands (3) has an outer envelope with a substantially cylindrical shape, the strands (3) being embedded in the receiving grooves (6) without otherwise making the fins (5) that separate them creep. The invention also relates to a one-piece core (2, 7) for a traction rope and also to the use of this rope (1) purely as a traction rope or as a carrying-hauling rope.
