Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Schmieren einer Linearführung anzugeben, das gegenüber dem genannten Stand der Technik insbesondere hinsichtlich eines kompakten Aufbaus der Linearführung bei gleichzeitig hoher Zuverlässigkeit und Verschmutzungsunempfindlichkeit weiterentwickelt ist.The invention has for its object to provide a method for lubricating a linear guide, which is further developed compared to the cited prior art, in particular with regard to a compact construction of the linear guide with high reliability and dirt immunity.
Diese Aufgabe wird erfindungsgemäß gelöst durch das Verfahren gemäß Anspruch 1 und durch eine Linearführung gemäß den Ansprüchen 2 bis 6, die nach dem Verfahren gemäß Anspruch 1 geschmiert wird.This object is achieved by the method according to claim 1 and by a linear guide according to
Im Folgenden im Zusammenhang mit dem Nachschmierverfahren erläuterte Ausgestaltungen und Vorteile der Erfindung gelten sinngemäß auch für die Vorrichtung, das heißt für die Linearführung, und umgekehrt.Embodiments and advantages of the invention explained below in connection with the relubrication method also apply correspondingly to the device, that is to say for the linear guide, and vice versa.
Die Linearführung ist vorzugsweise als Wälzlagerung ausgeführt. Sie umfasst mindestens einen linear auf einer Schiene verfahrbaren Schlitten sowie ein Nachschmiersystem, welches der Zuführung von Schmiermittel, das heißt Öl oder Fett, zum Schlitten dient, wobei am Schlitten ein Schwingungssensor angebracht ist, der mit dem Nachschmiersystem zusammenwirkt.The linear guide is preferably designed as a rolling bearing. It comprises at least one carriage which can be moved linearly on a rail and a relubrication system which serves to supply lubricant, that is to say oil or grease, to the carriage, wherein the carriage is fitted with a vibration sensor which cooperates with the relubrication system.
Die Erfindung geht von der Überlegung aus, dass ein Schlitten eines Linearführungssystems Eigenschwingungen aufweist, deren Amplituden und damit deren Energiewerte der Schwingungen des Schlittens, vom Schmierungszustand abhängig sind. Die Amplituden von Schwingungen liegen hierbei typischerweise im Bereich von wenigen Nanometern. Hauptsächlich werden die Schwingungsfrequenzen durch die Wälzkörper der Linearführung angeregt, wobei die Anregung vom Schmierzustand abhängig ist. Der Energiewert einer bestimmten Schwingungsfrequenz ist als sogenannte „Spike Energy“ messtechnisch erfassbar. In diesem Zusammenhang wird auch von der Pulsenergie eines Schwingungsereignisses gesprochen.The invention is based on the consideration that a carriage of a linear guide system has natural oscillations whose amplitudes and thus their energy values of the vibrations of the carriage are dependent on the lubrication state. The amplitudes of oscillations are typically in the range of a few nanometers. Mainly the vibration frequencies are excited by the rolling elements of the linear guide, the excitation is dependent on the lubrication state. The energy value of a certain oscillation frequency can be detected metrologically as so-called "spike energy". In this context, the pulse energy of a vibration event is also discussed.
Solange die Wälzkörper der Linearführung gut geschmiert sind, sind die Amplituden der Eigenfrequenzen typischerweise sehr klein. Wird der Kanal, in welchem die Wälzkörper abrollen, im Laufe des Betriebs der Linearführung dagegen trocken, so steigen die Amplituden signifikant an, was eine Auswertung des Energiewertes der Schwingung, das heißt der Pulsenergie, ermöglicht. Der Energiewert ist in jedem Fall von der Verfahrgeschwindigkeit des Schlittens abhängig. Steigt der auf eine bestimmte Verfahrgeschwindigkeit bezogene Energiewert zum Beispiel um 50 % oder das Doppelte an, jeweils bezogen auf einen eingelaufenen Referenzzustand der Linearführung, dann kann eine solche Grenzwertüberschreitung dazu genutzt werden, einen Nachschmierimpuls auszulösen.As long as the rolling elements of the linear guide are well lubricated, the amplitudes of the natural frequencies are typically very small. On the other hand, if the channel in which the rolling elements roll is dry during operation of the linear guide, the amplitudes increase significantly, which allows an evaluation of the energy value of the oscillation, that is to say of the pulse energy. The energy value depends in each case on the travel speed of the carriage. If, for example, the energy value relating to a certain travel speed increases by 50% or twice, in each case based on a run-in reference state of the linear guide, such a limit value overrun can be used to trigger a relubrication pulse.
Der Grenzwert des Energiewerts kann für eine neuwertige und eingelaufene Linearführung unter Referenzbedingungen angegeben werden. Die Referenzbedingungen sehen vor, dass der Schlitten ohne Betriebslast mit einer Referenzgeschwindigkeit verfahren wird. Wenn der Schlitten der ausreichend geschmierten Linearführung verfahren wird kann unter diesen Referenzbedingungen ein typischer Energiewert beobachtet werden. Dieser typische Energiewert dient der Ermittlung des Grenzwertes. Beispielsweise kann festgelegt werden, dass bei einer Überschreitung des typischen Energiewertes um wenigstens 50 Prozent der Nachschmierimpuls ausgelöst wird.The limit value of the energy value can be specified for a new and run-in linear guide under reference conditions. The reference conditions stipulate that the carriage is moved with no reference load at a reference speed. If the carriage is moved sufficiently lubricated linear guide can be observed under these reference conditions a typical energy value. This typical energy value serves to determine the limit value. For example, it can be determined that when the typical energy value is exceeded by at least 50 percent, the relubrication pulse is triggered.
Auf diese Weise ist eine adaptive Schmierung realisiert, die auf gemessenen schwingungstechnischen Eigenschaften basiert. Die schwingungstechnischen Eigenschaften sind hierbei von äußeren Einflüssen, beispielsweise einem äußeren Verschmutzungszustand, weitgehend unabhängig.In this way, an adaptive lubrication is realized based on measured vibration properties. The vibration characteristics are largely independent of external influences, such as an external pollution state.
Erfindungsgemäß werden nicht nur in der beschriebenen Weise Nachschmierimpulse ausgelöst, sondern auch die Zeitintervalle zwischen aufeinander folgenden Nachschmierimpulsen erfasst. Nachdem eine die Linearführung aufweisende Maschine in Betrieb genommen wurde, verlängern sich die Nachschmierintervalle zum Beispiel in den ersten Monaten des Gebrauchs, was auf das Einlaufen der Führungslaufbahnen der Linearführung zurückzuführen ist. Nachdem sich die Nachschmierintervalle verlängert haben, können sie insbesondere durch innere Verschmutzungen oder Pittingbildung wieder kürzer werden. Je nachdem, welche Nachschmierparameter eingestellt sind, sind unterschiedliche weitere Entwicklungen der Nachschmierintervalle möglich, wobei insbesondere zu berücksichtigen ist, dass durch jeden Nachschmiervorgang Partikel, welche sich im Schmiermittel befinden und sowohl die Schmierungseigenschaften als auch die schwingungstechnischen Eigenschaft beeinflussen, verdrängt werden. In anlagenspezifischer Weise kann die Zeitspanne zwischen aufeinander folgenden Nachschmierimpulsen mit einer Restlebensdauer der Linearführung korreliert werden. Die Zeitspanne wird unter den oben beschriebenen Referenzbedingungen erfasst.According to the invention, relubrication pulses are not only triggered in the manner described, but also the time intervals between successive relubrication pulses are detected. After a machine having the linear guide has been put into operation, the regreasing intervals are extended, for example, in the first few months of use, which is due to the run-in of the guide tracks of the linear guide. After the relubrication intervals have become longer, they can become shorter again, in particular due to internal contamination or pitting. Depending on which relubrication parameters are set, different further developments of the relubrication intervals are possible, whereby in particular it must be taken into account that any relubrication process displaces particles which are present in the lubricant and influence both the lubrication properties and the vibrational properties. In plant-specific manner, the time span between successive Nachschmierimpulsen can be correlated with a residual life of the linear guide. The time span is detected under the reference conditions described above.
Der Schwingungssensor ist vorzugsweise zur Aufnahme von Schwingungen zwischen 14 kHz und 25 kHz ausgelegt. In bevorzugter Ausgestaltung ist der Schwingungssensor an einem Stahlkörper des Schlittens der Linearführung befestigt. Hierbei bildet der Stahlkörper vorzugsweise zugleich eine Wälzkörperlaufbahn, das heißt eine Laufbahn für Kugel oder Rollen, der Linearführung.The vibration sensor is preferably designed to absorb vibrations between 14 kHz and 25 kHz. In a preferred embodiment, the vibration sensor is attached to a steel body of the carriage of the linear guide. In this case, the steel body preferably also forms at the same time a rolling body raceway, that is to say a raceway for ball or rollers, the linear guide.
Im Vergleich zu herkömmlichen Schlitten von Linearführungen ohne schwingungstechnische Messsysteme ist der Schwingungssensor praktisch ohne zusätzlichen Raumbedarf in den Schlitten der Linearführung integrierbar. Optional ist die Linearführung zusätzlich mit einem Längenmesssystem ausgerüstet.In comparison to conventional slides of linear guides without vibration measuring systems, the vibration sensor can be integrated into the slide of the linear guide practically without any additional space requirement. Optionally, the linear guide is additionally equipped with a length measuring system.
