Problems solved by technology

However, in the sense that by structuring or surface patterns, for example similar to the tread of a tire, there is a very serious influence on the noise emission, these measures are not considered effective in the prior art
Optimizing the frictional pairing between belts and pulleys in terms of transmitting as much torque as possible with as little noise emission as possible is therefore a rather demanding and difficult process due to conflicting objectives

Embodiment Construction

[0033] figure 1 The use of the flat belt according to the invention inside an elevator system 1 is shown in the form of a schematic diagram. Here is an elevator system / lifting device in the form of a 2:1 suspension in which the belt ends are fastened to the shaft head of the elevator shaft. The car 2 and the counterweight 3 are respectively suspended on a sling formed as a flat belt 5 by means of deflection rollers 4a, 4b.

[0034] The sling made of elastomer material has a flat drive side 8 and is driven by a traction or drive wheel 6 driven by a motor not shown further, which is arranged in the upper region of the elevator shaft between the car and the counterweight . This resulted in a simple pulley block. Thereby, the traveling speed of the flat belt 5 is twice the running speed of the car 2 . The pulling force is transmitted to the drive wheel 6 by the surrounding frictional force. The deflection rollers 4a and 4b are also surrounded by the flat belt 5 in a rotating ...

Abstract

Tension belt or harness made of elastic material with an essentially flat drive side, in particular an elevator belt, in which tension carriers or cords running parallel in its longitudinal direction are embedded in the elastic material of the tension belt or harness , and the tension belt or harness swivels around the pulleys and / or deflection rollers of the belt drive, thereby driving, turning or guiding the tension belt or harness, wherein the flat drive side of the tension belt or harness is provided with a or A plurality of grooves, wherein portions of the grooves extend with varying inclinations relative to the longitudinal direction of the belt and have a periodicity in the longitudinal direction of the belt, wherein, within one period, the orientation of the individual groove portions relative to the longitudinal direction or The inclination is formed such that the lateral force components induced by the orientation or inclination of the grooves and acting on the latter during the rotation of the belt are balanced.

Description

technical field [0001] The invention relates to a tension belt or sling made of elastic material with a substantially flat drive side, in particular an elevator belt, in which is embedded in the elastic material of the tension belt or sling a parallel running in its longitudinal direction A tension carrier or cord, and the tension belt or sling swivels around the pulleys and / or rollers or deflecting rollers of the belt drive, whereby the tension belt or sling is driven, deflected or guided, wherein the tension belt or sling is The flat drive side is provided with one or more grooves. Background technique [0002] Ribbon spreaders have become increasingly common in lift technology over the years. In particular, mention is made here of elevator belts designed as flat belts, which are guided by cabochon drive rollers or drive pulleys and deflection rollers or deflection pulleys, on which the belt can be centered by the convexity. [0003] Drive-side patterns of flat belts or ...
