Description
- LAUFRAD- WHEEL
Bei den Wagen YOn Seilbannen dient als Verbindung zwischen dem Fahr- bzw. haufwerk und der Fahrbahn (Drahtseil oder Schiene) das laufrad, vielfach auch Laufwerksrolle bezeichnet .In the YO n cable trolleys, the running wheel, often referred to as the running gear, serves as the connection between the carriage or pile and the roadway (wire rope or rail).
Industrie-Seilbahnen (Güterseilbahnen) sind bisher hauptsächlich mit Laufrädern einteiliger Bauart betrieben worden, hergestellt aus einem harten Stahlguss oder Schmiedematerial, welche Ausführungsart im Schema Figur 1 der Zeichnung zeigt. Dabei wurde die Stahlfestigkeit des Laufrades oder die Oberflächenhärtung der Laufrille der der Fahrbahn (Seil oder Schiene) angepasst, um den durch die Berührung zwischen Rolle und Fahrbahn unvermeidbaren Verschleiß den Laufrädern zu überantworten, weil sie dJs billigeren und leichter zu erneuernden ^-'eile sind.Industrial ropeways (goods ropeways) have so far mainly been operated with one-piece wheels, made of a hard cast steel or forged material, which embodiment is shown in the scheme of Figure 1 of the drawing. The steel strength of the impeller or the surface hardening was determined the running groove of the roadway (rope or rail) is adapted to the contact between the roller and the roadway to leave unavoidable wear and tear on the impellers, because they are cheaper and easier to replace.
Trotz dieser Festigkeits-Differenzierung hat die Praxis gezeigt, daß mehrfach schon nach relativ kurzer Betriebszeit und oft mittlerer Leistungsstufe der Materialseilbahnen, an den Fahrbahnseilen Drahtbrüche der. Jj.auf flächen eintreten, und sich starker.. Verschleiß bemerkbar machte .Despite this differentiation in strength, practice has shown that several times after a relatively short operating time and often medium performance level of the material ropeways, on the ropes Wire breaks in the. Jj. Step on surfaces, and become stronger .. Made wear and tear noticeable.
Als Ursache hierfür wurden u.a. extrem höhe Flächenpressungen, ungünstige Querbelastungsverhältnisse zwischen Seilspannung und Raddruck, und die harte Lauffläche der Stahlgzss-Laufräder ermittelt. The causes for this were, among other things, extremely high surface pressures, unfavorable transverse load ratios between rope tension and Wheel pressure, and the hard running surface of the steel gzss impellers is determined.
Dies führte zu der Überlegung, diese Stahl-Laufräder einteiliger Bauart in der Lauffläche mit einer seilschonenden Fütterung zu versehen. Versuche, diese Rollen mit einem Kunststoff auf der Basis von Polyester und Isocyanat (Vulkollan) duroh aufgießen zu ummanteln, schlugen fehl. Es war nur möglich, die Stahlräder in der Lauffläche geringfügig nachzudrehen und konnte man nur eine dünne Ummantelungsschicht aufgießen, weil sonst der ursprüngliche Lauf-jZf der Rolle überschritten worden wäre. Die dünne Ummantelungsschicht löste sich infolge Walkarbeit rasch vom Unterbau , erhöhte der Fahrwiderstand rapide und es kam schnell zur betrieblichen Unbrauchbarkeit solcher Rollen. Diese Ausführung besaß auch den Nachteil, daß die schweren Stahlgussrollen zur Umarbeitung dem Bearbeitungswerk eingesandt werden mussten, was nicht unerhebliche Frachtkosten verursachte.This led to the idea of making these steel impellers in one piece Design to be provided with a rope-friendly lining in the running surface. Try these roles with a plastic one Pour on the basis of polyester and isocyanate (Vulkollan) duroh to sheath failed. It was only possible to turn the steel wheels in the tread slightly, and that was only possible pour on a thin layer of coating, otherwise the original Lauf-jZf of the role would have been exceeded. The thin coating came off as a result of flexing quickly from the substructure, the driving resistance increased rapidly and such roles quickly became operationally unusable. This version also had the disadvantage that the heavy cast steel rolls were sent to the processing plant for reworking had to be, which caused not inconsiderable freight costs.
Letztbeschriebener Nachteil ist auch ein G-rund dafür, daß sich das Verfahren, eingeschlissene Stahlgussräder einteiliger Bauart in der Lauffläche mit Polyamid zu umspritzen, nicht durchsetzte .The last-described disadvantage is also a reason for the fact that The process of overmoulding torn cast steel wheels of one-piece design in the running surface with polyamide does not asserted.
Demgegenüber betrifft die Erfindung ein Seilbahn-Laufrad geteilter Bauart mit einer auswechselbaren Lauf-Ringeinlage aus hartem Kunststoff vom Typ besonders druckfester Polyamide, alkalischer Schnell-Polymerisate (Blockpolymerisate) oder Polyäthylene.
