Cable lubricant

Abstract

A dry lubricant (50) for flexible traction members (10), in particular wire cables and / or stranded ropes for static and / or dynamic loads, is characterized in that a major percentage of the dry lubricant (50) consists of a polymer material. Furthermore, in a method for manufacturing a flexible traction member (12) made up of multiple tension-proof elements (1.1, 1.2,..., 1.7, 20), in particular wires and / or strands and / or ropes, a dry lubricant (50) is applied to the tension-proof elements (1.1, 1.2,..., 1.7, 20) before the latter are joined together, said dry lubricant (50) being sprayed onto the tension-proof elements (1.1, 1.2,..., 1.7, 20) in a fluid state.

Description

technical field [0001] The invention relates to a dry lubricant for flexible traction devices, in particular for statically and / or dynamically loaded wire ropes and / or plied wires. The invention furthermore relates to a method for producing a traction mechanism and the use of a dry lubricant for the production of a flexible traction mechanism. Background technique [0002] Especially in hoisting technology, in bridge construction and in general construction, deflectable traction means such as traction ropes or traction cables for example constitute crucial mechanical components which are able to transmit traction forces. The deflectable traction means generally consist of a plurality of individual elements, such as wires or tensile fibers, which are twisted and / or twisted to form litzes, for example, and serve as traction means. Multiple litz wires may also be twisted or twisted to form a larger cable or traction mechanism, and / or may have a common sheath, for example made ...

AI Technical Summary

Problems solved by technology

However, especially in dynamic applications, varying loads and / or reciprocating operations (Walkarbeit) cause lubricants in fluid and / or powder form to be pressed or squeezed out of the traction mechanism over time, which leads to Deterioration of their lubricating effect in the traction mechanism

In addition, the lubricant pressed out of the traction mechanism can cause, for example, contamination of mechanical parts that come into contact with the traction mechanism

This is a disadvantage, especially in the case of friction drives, which are commonly used in the transmission sector, since in this case lubricants are generally not used in the traction mechanism and at the expense of accelerated wear of the traction mechanism
