摘要:
A method of manufacturing a belt for an elevator system includes the steps of: manufacturing a first belt part that has an arrangement of grooves, in particular in the lengthwise direction of the belt; arrangement of a tension bearer in at least one of the grooves; and connection of a second belt part with the first belt part whereby the tension bearer is accommodated in the interior of the belt.

An elevator system includes a roller arrangement and a belt for supporting an elevator car. The roller arrangement has two rollers with approximately parallel axes of rotation and structured circumferential surfaces engaging a complementary structured surface of the belt. The structured surfaces have alternating ribs and grooves. The belt is twisted about its longitudinal axis between the two rollers to keep the structured surfaces in contact and forms an under-looping for support of the elevator car.

An elevator installation includes an elevator car, at least one guide rail for vertical guidance of the elevator car, and two support devices, such as ropes or belts, that support a counterweight at one side of the elevator car and underloop the elevator car. Each of the two support devices has one end at a fixing point at one side of the elevator car. A rocker device has two arms and is fastened to the guide rail to provide a rocking movement. Each of the support devices has an opposite end at a fixing point on an associated one of the and the rocking movement provides a length compensation in the case of unequal lengthening of the two support devices.

A wedge-ribbed belt supports an elevator car in a cantilevered mode and engages a drive pulley of a drive mounted at the head of an elevator shaft. The belt has a running surface facing the drive pulley with a plurality of ribs and grooves extending in parallel in a longitudinal direction of the belt. The ribs and grooves can be triangular-shaped or trapezium-shaped in cross section. A plane of the drive pulley is arranged vertically and at right angles to a car wall at a counterweight side of the elevator car.

An elevator installation is provided that includes an elevator cage, a drive pulley, at least one support means formed as a flat belt, and a drive engine which drives the at least one support means, which carries the elevator cage, by way of the drive pulley. In the elevator installation, the support means has, at least on a running surface facing the drive pulley, several ribs of wedge-shaped or trapezium-shaped cross-section which extend parallel in a longitudinal direction of the support means and further has several tensile carriers oriented in the longitudinal direction of the support means. The tensile carriers are sized so that a total cross-sectional area of all the tensile carriers amounts to 30%-40% of a cross-sectional area of the support means. The tensile carriers may be distributed in a transverse direction of the support means so that exactly two tensile carriers are associated with each of the ribs, the tensile carriers having an outer diameter equal to 35%-40% of a rib spacing (T).
摘要:
In an elevator, with an elevator car, a counterweight, a drive unit arranged below the counterweight and provided with a drive pulley, and an elevator support device, which is guided over the drive pulley and at least one deflecting pulley and which supports and moves the elevator car and the counterweight in opposite directions, at least one run of the support device, which leads to the drive pulley, is led through a cut-out in the counterweight.
摘要:
An elevator system has at least one elevator car and at least one counterweight which are displaced in opposing directions along at least one guide track in an elevator shaft by a supporting and driving apparatus that is guided by a drive pulley of a drive. The supporting and driving apparatus is fastened directly to the elevator car eccentrically with respect to a center of gravity of the elevator car so that a tilting or load moment results thereby, wherein the tilting or load moment can be compensated by a compensation device.

In an elevator element for driving or reversing an elevator suspension device in an elevator system, that interacts with an elevator suspension device, the arithmetic mean of the roughness value of the contact surface measured in the circumferential direction of the elevator element, and the mean roughness value of the contact surface measured in the axial direction of the elevator element, are different. The arithmetic mean roughness value of the contact surface measured in the circumferential direction of the elevator element is less than 1 micrometer.
摘要:
An elevator support for an elevator system includes a base body, a drive side with at least one drive rib, a deflecting side opposite the drive side with at least one guide rib, and a tensile carrier arrangement arranged in the base body. The guide rib has a greater flank height and/or a greater flank width than the drive rib. A ratio of the flank height of the guide rib to the width of the elevator support is at least 0.4. A respective guide rib is associated with at most three of the drive ribs.
