Description
Nach, dem Hauptpatent werden Ritzel auf dem Wellenstumpf von Bahnmotoren durch Aufschrumpfen derart befestigt, daß das Erwärmen zwecks Anlassens der gehärteten Ritzel gleichzeitig für den Aufsdhrumpfvorgang benutzt wird. Das Anlassen wurde deshalb unmittelbar vox oder beim Aufziehen des Ritzels auf den Wellenzapfen vorgenommen. Dadurch ergibt sich der Vorteil, daß das Aufschrumpfen mit einer höheren Erwärmung vorgenommen werden kann als sonst, denn bei vorherigem Anlassen und nachfolgendem Aufschrumpfen mit neuerlicher Erwärmung durfte die Erhitzung nicht zu hoch getrieben werden, um den Werkstoff nicht zu weich zu machen.According to the main patent, pinions are attached to the stub shaft of railway motors by shrink fitting in such a way that the heating for the purpose of tempering the hardened pinion is used simultaneously for the steaming-on process. The starting was therefore carried out immediately vox or when the pinion was pulled onto the shaft journal. This has the advantage that the shrinking can be carried out with a higher heating than usual, because with previous tempering and subsequent shrinking with renewed heating, the heating should not be increased too high in order not to make the material too soft.
Beim Anlassen muß nun gemäß den Betriebserfahrungen das· Erwärmen auf 180 bis 2oo° mindestens für 1 bis il/2 Stunde vorgenommen werden, um den erforderlichen Anlaßgrad zu erzielen. Diese Zeit ist aber verhältnismäßig zu lang, um einen wirtschaftlichen Zusammenbau des Ritzels mit der Welle zu ermöglichen.When tempering, according to operating experience, heating to 180 ° to 200 ° must be carried out for at least 1 to 1/2 hour in order to achieve the required degree of tempering. However, this time is relatively too long to allow economical assembly of the pinion with the shaft.
Erfindungsgemäß wird das Anlassen gegebenenfalls nur zum Teil durchgeführt und beim Aufziehen des Ritzels auf die Welle eine erneute kurzzeitige Erwärmung auf die Anlaßtemperatur vorgenommen. Es ergibt sich bei 'dieser Aufteilung der Arbeitsvorgänge der Vorteil, daß der Zusammenbau unabhängig von dem Anlassen gemacht wird. Bei Durchführung 'eines vollständigen Anlaßvorganges vor dem Aufschrumpfen kann außerdem in besonderen Fällen erreicht werden, daß heim zweiten zum Zwecke des Aufschrumpfens mit der Anlaßtemperatur vorgenommenen kurzen Erwärmungsvorgang der Baustoff entspannt und die Kerbfähigkeit erhöht wird.According to the invention, the tempering is optionally only partially carried out and when the pinion is pulled onto the shaft, it is briefly heated again to the tempering temperature performed. With this division of the work processes there is the advantage that the assembly is independent from the tempering is done. When carrying out a complete starting process Before the shrinking on can also be achieved in special cases that the second for the purpose of shrinking The brief heating process carried out with the tempering temperature relaxes the building material and increases its notchability will.
