Description
Verfahren und Einrichtung zur Schmierung und Kühlung von Zahnradgetrieben. Es gibt in der Technik Fälle, wo man für eine oder mehrere Maschinen, die von einer Stelle aus geschmiert werden, Ol von verschiedener Viskosität gebraucht. Insbe sondere trifft. dies bei geschmierten Zahn radgetrieben und. hierunter wieder bei sol chen mit grossen Übersetzungen und grosser Kraftübertragung zu, wo ein kleinerer oder grösserer Teil der Umfangskraft durch die zwischen den Zähnen befindliche Ölschicht übertragen wird, und es sich bekanntlich empfiehlt., für die Schmierung und Küh lung der Zähne ein möglichst dickflüssiges Öl zu verwenden.
Da jedoch dasselbe Ö1 auch für die Schmierung der Lager ver wendet werden soll, die mit Rücksicht auf Wärmeentwicklung und Reibungsarbeit ein dünnflüssigeres Öl verlangen, so musste bis her ein unliebsamer Kompromiss geschaffen werden. Man hat nun deslialb bereits Ver suche gemacht, für die Zahn- und Lager schmierung zwei verschiedene Ölsorten zu verwenden mit jeweils geeignetem Schub modul, was jedoch kaum zu verwirklichen ist, weil sich im Betriebe die ()le immer wieder mischen. Die vorliegende Erfindung erreicht den gleichen Zweek mit nur einer Ölsorte und ein und demselben Ölkörper bei Zahnrad getrieben dadurch, dass man das Öl für die Zähne tiefer kühlt als das Öl für die Lager.
Anhand der Zeichnung sei die Erfindung an Beispielen verschiedener Einrichtungen zur Ausfühung des des Verfahrens näher ver anschaulicht.
Fig. 1 zeigt schematisch eine Maschinen anlage mit einem Zahnradgetriebe im Grundrisse; Die Fig. \' und 3 stellen, ebenfalls sehe- mat.iscli, zwei verschiedene Schmier- und Kühleinrichtugen an einer derartigen An lage mit blick auf eine Seite des Zahnrad getriebes dar.
In Fig. 1 ist a irgendeine schnellaufende Kraftmaschine. z. B. eine Dampfturbine, die durch das Bitzel b ihre Leistung auf das grosse Rad ülmrfrü;t. Die Welle d iii;(l dit, Welle e i-iiliuii iii Lagern hezw.
Lager und rigider werden nun zu n Bei spiel auf 1'iil1##ei.idc Weise du=r li (lassi--ll-)e Öl ,gespeist: Das. Öl wird in für die Schmierung der Wellen geeignetem Zustande, d. h. verhält nismässig dünnflüssig, den Lagern f und (Fig. 2) zugeführt, bei h wieder gesammelt und dann zum Teil wieder den Lagern durch Pumpe i. und Leitung )e und zum Teil durch Leitung Z und. Pumpe m dem Kühler n und darauf durch. Leitung o den Zähnen der Räder b und c zugeleitet, von wo es demselben Sammelgefäss h wie das Lageröl zufliesst.
Durch die Kühlung ist das Öl dickflüssiger und damit für die Schmie rung der Zähne geeigneter geworden. Die Mischung dieses dickflüssigen Öls mit dem dünnflüssigen Lageröl im Gefässe h kann nach erfolgter Schmierung der Zähne nicht nur ohne Bedenken erfolgen, sondern ist zur Verhütung einer unzulässigen Steige rung der Temperatur dieses von der Pumpe i im Kreislaufe geführten Öles sogar vorteil haft. Die Strömungsgeschwindigkeit der Teilströme kann voneinander verschieden gehalten werden. Fig. 3 zeigt. insofern eine Abänderung und Vereinfachung, als. nur eine Pumpe p das Öl durch Leitung k den Lagern f, g und durch den Kühler n hindurch auch den Zahnrädern b, c durch Leitung o zuführt.
Der Kühlung ist auf jeden Fall eine be sondere Sorgfalt zuzuwenden und zu be rücksichtigen, dass der den Kühler durch fliessenden Ölmenge die Kalorien, die sie selbst bei Schmierung .der Zähne, und die jenigen Kalorien, die die Lagerölmenge bei Schmierung der Lager aufnimmt, zu ent ziehen sind.
Method and device for the lubrication and cooling of gear drives. There are cases in the art where oil of different viscosity is used for one or more machines that are lubricated from one point. Especially hits. this with lubricated gear wheel drives and. including again for those with large gear ratios and high power transmission, where a smaller or larger part of the circumferential force is transmitted through the oil layer between the teeth, and it is well known that an oil that is as thick as possible for the lubrication and cooling of the teeth is recommended to use.
However, since the same oil should also be used for the lubrication of the bearings, which require a thinner oil due to the development of heat and friction work, an unpleasant compromise had to be found up to now. Deslialb attempts have now been made to use two different types of oil for tooth and bearing lubrication, each with a suitable thrust module, but this can hardly be achieved because the () oils keep mixing in the company. The present invention achieves the same purpose with only one type of oil and one and the same oil body in the case of gear driven by cooling the oil for the teeth more deeply than the oil for the bearings.
Based on the drawing, the invention is illustrated in more detail using examples of various devices for executing the method.
Fig. 1 shows schematically a machine system with a gear transmission in plan; FIGS. 1 and 3 show, also see iscli, two different lubricating and cooling devices in such a system with a view of one side of the gear transmission.
In Fig. 1, a is any high speed prime mover. z. B. a steam turbine that ülmrfrü; t its power to the big wheel by the Bitzel b. The wave d iii; (l dit, wave e i-iiliuii iii bearings hezw.
Bearing and more rigid are now fed to n example in 1'iil1 ## ei.idc way du = r li (lassi - ll-) e oil: That. Oil is in a suitable condition for the lubrication of the shafts, i. H. behaves moderately thin, fed to the bearings f and (Fig. 2), collected again at h and then partly back to the bearings by pump i. and line) e and partly through line Z and. Pump m the cooler n and then through. Line o fed to the teeth of the wheels b and c, from where it flows into the same collecting vessel h as the bearing oil.
The cooling makes the oil more viscous and therefore more suitable for the lubrication of the teeth. The mixture of this viscous oil with the thin bearing oil in the container h can not only be done without hesitation after the teeth have been lubricated, but is even advantageous to prevent an inadmissible increase in the temperature of this oil circulated by the pump i. The flow velocity of the partial flows can be kept different from one another. Fig. 3 shows. an amendment and simplification in that. only one pump p supplies the oil through line k to the bearings f, g and through the cooler n also to the gears b, c through line o.
In any case, special care must be taken with the cooling and care must be taken to ensure that the amount of oil flowing through the cooler receives the calories that it absorbs when lubricating the teeth and the calories that the amount of oil absorbs when lubricating the bearings are withdrawn.
