Description

Verfahren und Vorrichtung zum Beseitigen von Riffeln auf Schienen Auf den Fahrflächen der Schienen entstehen vielfach aus bisher noch nicht genügend geklärten Ursachen in geNvissen gleichmäßigen Abständen flache Mulden, sogenannte Riffeln. Diese sind für den Oberbau, Betrieb und Verkehr schädlich, weil sie die Befestigungsteile des Oberbaus lockern, Schwingungen und erhöhte Abnutzung bei den Fahrzeugen verursachen und ein starkes lästiges Fahrgeräusch hervorrufen. Die Riffeln können zur Zeit nur durch besondere kostspielige Schleifwagen oder durch Hobeln beseitigt «-erden. Im letzten Falle müssen die Schienen ausgebaut werden. Nach der Erfindung sollen die Riffeln durch elektrischen Induktiotisstroni in Verbindung mit Walzen beseitigt werden.Method and device for removing corrugations on rails On the running surfaces of the rails, there are often not enough so far clarified causes shallow hollows, so-called Corrugations. These are harmful to the superstructure, operation and traffic because they are the Fastening parts of the superstructure loosen, vibrations and increased wear in the Cause vehicles and produce a strong annoying driving noise. The corrugations can currently only be done by special expensive grinding trolleys or by planing eliminated «-earth. In the latter case, the rails must be removed. After Invention intended to connect the corrugations by electrical Induktiotisstroni be eliminated with rollers.
