Abstract:
PROBLEM TO BE SOLVED: To provide a support drive means of a synthetic fiber cable by appropriate transmission of tensile force from a strand layer to another strand layer. SOLUTION: In this synthetic fiber cable 1, the strands of the strand layer are mutually spaced apart. With the mutual spacing d1, the strands 7 of the outer strand layer 2 can move radially in the direction of the cable center and exert a radial pressure on the strands 8, 9 of the first inner strand layer 3. The radial pressure is passed on from the strands 8, 9 of the first inner strand layer 3 to the strands 10 of the second inner strand layer 4. The radial pressure is passed on from the strands 10 of the second inner strand layer 4 to the core strand 5. The radial pressure increases inwardly from strand layer to strand layer. The soft cable sheathing 6 does not act as a support between the strands 7 in circumferential direction Ur. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To create a support driving means which keeps a flexure stress lower in a tension carrier. SOLUTION: The support driving means (11) has a geometric form of a belt made up of a belt main body (12) or a sheath (12) which surrounds the tension carrier (1). A belt running surface (16) is flat and can be parallel with a backside (13) of the belt or can have a trapezoidal or semi-circular rib (14) and a groove (15). A contour of a driving pulley or a biasing pulley is approximately complementary with the belt running surface. One or more tension carries (1) are provided for each rib (14) and the tension carriers (1) are twisted alternately or together in Z and S directions. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
The invention relates to an elevator supporting means, comprising two or more tension members which extend in the longitudinal of the supporting means and are embedded in a sheath, wherein each tension member has a torque under tension, and wherein a sum of all torques of the tension members in a supporting means results in approximately zero.
Abstract:
This supporting and drive means (11) has the geometry of a belt consisting of a belt body (12) or sheathing (12) which encloses the tensile carriers (1). The running surface (16) of the belt can be flat and parallel to the belt back (13) or have trapezium- shaped or semicircular ribs (14) and grooves (15), wherein the profile of a drive pulley or of a deflecting pulley is approximately complementary to the running surface of the belt. One or more tensile carriers (1) are provided for each rib (14), wherein the tensile carriers (1) are laid or stranded alternately in Z direction and S direction.
Abstract:
The drive unit (11) has two tensile carriers (1) extending at a spacing from one another axially parallel to a longitudinal axis of the drive unit and embedded in a sheathing (12). Each of the tensile carriers includes strands arranged in one strand layer, where each strand is formed from stranded threads, which are embedded in a matrix material and constructed from synthetic fibers, for improved connection between the sheathing and the matrix material. A Shore hardness of the sheathing is approximately equal to a Shore hardness of the matrix material.
