Problems solved by technology

[0012] Therefore, such belts cannot be used in safety-sensitive installations, such as elevator installations, or can only be used conditionally, since the potential risk of a situation in which the belt breaks due to the aforementioned damage is too high
Likewise, such belts cannot be used to transmit large forces, due to the increased risk of such damage in this case

Embodiment Construction

[0046] figure 1 A cross-section of the belt 12 according to an embodiment of the present invention is shown. This includes a first portion of the belt 13 of thermoplastic material (polyamide in the embodiment). The first part of the belt 13 is produced by extrusion, wherein during the production of the first part of the belt 13 a tensile carrier 14 consisting of a plurality of standard steel wires is supplied to the first part of the belt 13 so that the tensile carrier 14 is completely contained and fixed In the finished first part of the belt 13. Then, the second part of the belt 15 of elastomer (polyurethane in the embodiment) is pressed onto the first part of the belt 13 . In that case, the side of the second part belt 15 remote from the first part belt is configured as a traction surface which is arranged to be in contact with the drive pulley 4.1 having a wedge-shaped rib profile on its running surface (see figure 2 )Cooperate. For this purpose, the traction surface ...

Abstract

A belt (12) for the elevator device comprises the following components: a first part belt (13) of the first material; a stretching-proof carrier arrangement with at least one stretching-proof carrier (14) which is disposed at the first part belt; and a second part belt (15) of the second material. The first material includes the thermoplastic plastic which is used for bearing and distributing thelocal region pressure that is leaded by the stretching-proof carrier.

Description

technical field [0001] The present invention relates to a belt for an elevator installation, a method of manufacturing such a belt and an elevator installation having such a belt. Background technique [0002] Elevator installations include an elevator car and generally a counterweight, which can be moved in the elevator shaft or along self-supporting guides. In order to generate the movement, the elevator installation comprises at least one drive unit with at least one drive pulley which carries the elevator car and counterweight via one or more belts and / or transmits the required driving force to the elevator car on the carriage and counterweight. [0003] In the case where the elevator car and the counterweight can be connected by the same belt, the belt is guided on the drive pulley or pulleys and serves not only as a support but also as a drive. Alternatively, the elevator car and counterweight can also be carried by separate support belts and driven by separate drive...
