Description

Sinterlager i:iit erhöhter Lebensdauer Die Lebensdauer eines Sinterlagers ist von einer Reihe von Faktoren abhängig, wobei die Erhaltung der notwendigen Schmiermittelmenge als sehr wesentlich anzusehen ist.Sintered bearing i: with increased service life The service life of a sintered bearing depends on a number of factors, with maintaining the necessary amount of lubricant is to be regarded as very essential.

Schmiermittelverluste entstehen vor allem durch Abschleudern von der Welle, Verdunstung und dadurch, daß bei laufender Welle durch den entstehenden Öldruck das Schmiermittel durch die LaE;erwandung nach außen gedrückt wird und abtropft.Loss of lubricant is mainly caused by being thrown off the Wave, evaporation and by the fact that when the wave is running due to the resulting oil pressure the lubricant is pressed outwards through the wall and drips off.

Vor allem bei Kalottenlagern, die wehen der guten Einstellbarkeit an der Außenfläche freiliegen, treten diese zrscheinungen in stärkerem i,:aGe auf. Auch bei eingepreßten oder eingei:lebten zylindrischen Sinterlagern wird das Schmieröl an den freiliegenden Stirnflächen herausgepumpt und geht für die Schmierung verloren.Especially with spherical bearings, which are easy to adjust If they are exposed on the outer surface, these appearances are more pronounced i,: aGe. The lubricating oil is also used in the case of pressed-in or live-in cylindrical sintered bearings pumped out at the exposed end faces and is lost for lubrication.

In der Praxis sucht man diesen Vorgängen durch Anbringunb einer ulrUckfUhrung zu begegnen, derart, da- abtropfendes oder abgeschleudertes Schmiermittel von Filzen aufgefangen wird und durch Kapillarkräfte wieder dem Lagerkörper zugeführt wird. In practice, attempts are made to counteract these processes by attaching an ultrasonic return, in such a way that dripping or thrown-off lubricant is caught by felts and fed back to the bearing body by capillary forces .

Diese konstruktiven Maßnahmen sind jedoch nicht nur eine Kostenfrage sondern häufig aus Platzgründen nicht durchführbar.However, these constructive measures are not just a question of cost but often not feasible due to lack of space.

Es sind bereits Verfahren bekannt, bei denen durch Aufbringung von Lack die Poren an der Außenfläche des Sinterlagers verschlossen wer- den sollen. Verfahren dieser Art sind jedoch für große Stückzahlen uiigeeiUnet, wobei außerdem die Gefahr besteht, daii Lackmeni;en in die Bohrung gelangen und das Laufverhalten des Lagers nachteilig beeinflussen.Methods are already known in which the pores on the outer surface of the sintered bearing are to be closed by applying paint. Processes of this type are, however, unsuitable for large numbers of items, and there is also the risk that lacquer will get into the bore and adversely affect the running behavior of the bearing.

Weiterhin ist es bekannt, -die an der Oberflache von Sintermaterial liegenden Poren durch eine lro...meltiehandlung zu schließen. Dieses Verfahren wird jedoch ausschließlich bei Sinterformteilen allgewandt, um ein hindrin,;en von Elektrolyt-Flüssigkeiten bei galvanischen Behandlungen zu vermeiden.It is also known -the on the surface of sintered material to close lying pores by a rom ... This procedure However, it is only used for sintered molded parts in order to prevent Avoid electrolyte fluids during galvanic treatments.

An Sinterlagern und Sinterformteilen wird zur Beseitigung von Gratbildung ebenfalls eine Trommelbehandlung durchgeführt. Die behandlungsdauer liegt jedoch im Bereich von 5 - 10 min und wird so kurz wie möglich gehalten.Burr formation is removed from sintered bearings and sintered molded parts drum treatment was also carried out. However, the duration of treatment is in the range of 5 - 10 minutes and is kept as short as possible.

Gemäß der vorliegenden Erfindung wird das Sinterlager vor dem Kalibrieren einer Trommelbehandlung von'10 bis Lehr als 30 min unterworfen, die ausschlieUlioh zum Verschluß der außenliegenden Poren gegen Ülaustritt dient. Die Behandlungsdauer richtet sich r:ach @;-rkstoff und Größe des La- gers, sowie nach der bleichzeitig in der Tro n.,el bei.aii%elten St':ck- zahl. Sei den erfindungsgemä3 behanLelten S'_nterlagern wurde. nach dem, Kalibrieren d'_e bei :;onstantem Druck von ; atü :urch die Lr:ger;-ran- dun;@ hindurchgedi#.ickte @lr.:e:.ts bestimmt. Bei nicht behanLel ten LagLrn betrug diese @l:@enge 12,5 - 13,5 cm3/h. Be; 15 min behandelten La;-ern betrug diese Ülmenge 6,5 - 8,0 cm 3/h. Bei 30 min behandelten Lagern betrug diese blLierge 1,5 - 2,5 cm3/h. Die Gesartölaufnalime der Lager wurde ;furch die 3ahandlung nic:.t beeinflulj't. Bei der Durchf-:irung des Verfahrens hat es sich als günstig herausgestellt, bei ::ohen Anforderungen an die ::ohrun @stoleranz Lager mit abgesetzter Bohrung zu verwenden. Die innere Lauffläche des Lagers wird dabei durch die beiderseits überstehenden Aufsenmantelflächen gegen jede Verfor:°,ung bei der Trommelbehandlung geschützt.According to the present invention, before calibration, the sintered bearing is subjected to a drum treatment from 10 to 20 minutes, which is used exclusively to seal the outer pores against leakage. The duration of treatment depends on r: ach @; - material and size of the gers, as well as after the pale in the trough., el bei.aii% elten St ': ck- number. If the S'_interlager were treated according to the invention. after, Calibration d'_e at:; constant pressure of; atü: urch the Lr: ger; -ran- dun; @ durchgedi # .ickt @lr.: e: .ts definitely. In the case of untreated bearings, this was 12.5 - 13.5 cm3 / h. Be; La; -ern treated for 15 min, this amount of oil was 6.5-8.0 cm 3 / h. In the case of bearings treated for 30 minutes, this volume was 1.5-2.5 cm3 / h. The social security record of the camps was not influenced by the action. When carrying out the process, it has been found to be advantageous to use bearings with a stepped bore if the :: ohrun @toleranz requirements are not met. The inner running surface of the bearing is protected against any deformation during the drum treatment by the outer circumferential surfaces protruding on both sides.
