Definitions
- the present invention relates to a ball stud, particularly in a pattern assembly of a warp knitting machine, having a first end having at least part of a spherical shape, a second end and a portion between the first end and the second end, at least part of the ball stud having a cavity having, which is fluidly connected by at least one channel with an outer peripheral surface.
- One area of application of the present invention is in the area of a warp knitting machine between a guide bar and a pattern arrangement.
- previous ball pins have oil temperature control systems in which oil flows over the ball pin. These systems are maintenance-intensive because the oil absorbs dust or other contaminants and transports them through pipes.
- oil temperature control systems are very susceptible to contamination due to the high dust content. These usually get caught in places that are particularly difficult to access and clog the lines after a certain time. The contamination must be removed as part of maintenance. This is not only time-consuming, but also involves a great deal of cleaning work.
- U.S. 2016/0363162 A1 describes a ball stud having a cavity, a first end and a second end.
- the first end has a spherical shape with channels connecting a vicinity of the ball stud to the cavity.
- a threaded portion is provided at the second end.
- a cylindrical section with radially extending channels is arranged between the first end and the second end.
- DE 43 16 395 C1 describes a warp knitting machine with displaceable bars in which ball joints are provided between the bar and the pattern device connected ram.
- the tappet has a cavity, the cavity being connected to an oil supply.
- the tappet is lubricated and cooled by the oil.
- the object on which the invention is based is to reduce the adjustment effort of the warp knitting machine and the maintenance effort of a ball pin.
- a surface of the ball pin is enlarged by the element.
- a large surface can give off more heat to the environment than a small one Surface. This allows you to achieve an even temperature of the ball pin.
- the uniform temperature enables relatively precise compliance with tolerances. Exact adherence to tolerances prevents the bolt from being destroyed or worn out, which increases the reliability of the knitting process.
- the channel is preferably arranged in the radial direction. Manufacturing the radially arranged channel involves little effort. Furthermore, ball pins are usually designed as rotationally symmetrical components, so that the cavity is usually designed as a bore, with an axis of the bore coinciding with an axis of the ball pin. The radially arranged channel thus guarantees the connection between the cavity and the outer peripheral surface.
- Two channels are preferably arranged diametrically in each case. This arrangement allows two channels, a pair of channels, to be manufactured with one bore, which makes the production of the ball pin economical.
- the section has one or more fluid guide elements between the outer peripheral surface and the element.
- the fluid guide element allows a fluid flowing through the cavity and the channel to strike the element in a targeted manner. This prevents the fluid from accumulating and ensures that heat is dissipated from the ball stud.
- the fluid guide element creates a distance between the channel and the element, which in turn is beneficial for a distribution of the fluid. The distribution allows for greater heat dissipation, which keeps the temperature even.
- the fluid guide elements are ring-shaped.
- Annular fluid guide elements can be manufactured using lathes, resulting in substantially low costs.
- the element is divided into sections by ring-shaped fluid guide elements, which can be further adjusted if necessary.
- a fluid guide element is preferably arranged between adjacent channels.
- the fluid guide element does not conflict with channels and thus does not interfere with the function of the channels. Furthermore, this creates heat transfer between the ball stud and the element.
- the fluid directing elements allocate a section to each channel or pair of channels, which can be adjusted according to needs.
- the element has a fluid-permeable structure.
- fluid can flow through the channel and the element from the cavity. While the fluid is in contact with surfaces of the ball stud and element, it absorbs heat and expels it to the outside.
- the fluid-permeable structure increases the surface area with which the fluid is in contact and thus the surface area over which the fluid can absorb heat. This improves heat dissipation from the ball stud.
- the element is at least partially porous.
- Porous elements have a large surface area in relation to their volume. A large surface area to volume ratio results in a large surface area, which is used for heat transfer to the fluid, without the element having to be designed too voluminous for a given installation space. Accordingly, the fluid can absorb more heat and take it with it.
- the element is preferably designed as a sintered element.
- the element can be produced with a precise fit using a sintering process.
- the sintering process can produce a specific porosity, so that the element can have different porosities.
- the porosities can be adjusted according to a fluid flow to ensure optimal heat dissipation.
- the element is preferably connected to the section in a form-fitting manner.
- a positive fit guarantees heat transfer from the ball pin to the element.
- no further fasteners are required for assembly or disassembly. This reduces maintenance costs while improving heat exchange between the element and ball stud.
- a thermal compound can be used to improve heat transfer.
- the ball stud has a flow path through the cavity, channels and element.
- the ball stud is traversed by the cavity along the channels and through the element, thereby moving the fluid from the inside to the outside through the ball stud. This causes a pressure drop from the cavity to the outside. This prevents dirt, dust, impurities or the like from getting into the ball stud. This makes maintenance easy.
- a filter arrangement is preferably arranged in the flow path.
- the filter assembly prevents dirt, dust, debris or the like from entering the ball stud and clogging the element.
- the filter can be installed in an easily accessible location in a fluid supply to the ball stud, or directly in the cavity of the ball stud. During normal scheduled maintenance, the filter can be checked for possible contamination and any necessary steps are taken. This prevents the element from clogging and keeps the ball stud within an optimal temperature window.
- the ball stud has a fluid port that is connected to a fluid source.
- the ball stud is in fluid communication with a fluid source through the fluid connection. This makes it possible for the fluid to flow through the ball stud. A forced flow ensures an even temperature of the ball pin.
- the fluid conveyed by the fluid source is air.
- the ball pin can be flowed through by a low-pressure generator, such as a machine fan.
- the ball stud can be connected to a compressed air connection. No additional peripherals are required. Thus, the acquisition costs remain low.
- 1 1 shows a ball stud 1 having a first end 2, a second end 3 and a portion 4 between the first end 2 and second end 3.
- the section 4 has channels 5 and 6 fluid guide elements. Fluid elements 6 are arranged on an outer peripheral surface 7 . Furthermore, an element 8 is shown.
- the first end 2 is connected to a mating counterpart, not shown.
- the second end 3 has attachment options, for example a thread or the like, on to mount the ball stud 1 .
- the ball pin 1 has a cavity 9, which connects the channels 5 with the outer peripheral surface 7.
- the channels 5 are arranged radially, starting from the cavity 9 .
- two channels 5 are arranged diametrically.
- several diametrically arranged channels 5 are parallel to each other.
- On the outer peripheral surface 7 fluid guide elements 6 are arranged.
- the fluid guiding elements 6 are arranged between two channels 5 and on an edge of the section 4 .
- the element 8 is in turn arranged on the fluid guide elements 6 .
- the fluid guide elements 6 are ring-shaped, as is the element 7.
- the section 4, fluid guide elements 6 and the element 7 are in a geometric relationship. A form fit between the fluid guide elements 6 and the element 8 can be produced by this geometric relationship.
- a filter 10 is arranged at the second end 3 .
- the arrows shown represent the flow path of a fluid.
- the element 8 can be produced by a sintering process.
- the sintering process can realize a fluid-permeable structure of the element 8 .
- the sintering process also enables the production of porous elements.
- the element 8 can have local fluid-permeable structures or porous structures. The sintering process can realize such structures.
- fluid enters cavity 9 at second end 3 of ball stud 1 .
- the fluid flows from the cavity 9 through the channels 5 in the direction of the outer peripheral surface 7, in order to finally flow through the element 8, guided there by the fluid guide elements 6.
- the fluid While the fluid is in contact with the ball stud 1 or the element 8, the fluid absorbs heat from the ball stud 1 and transports it to the outside.
- the element 8 increases a surface used for heat dissipation many times over, which benefits heat transfer from the ball pin 1 to the fluid.
- the temperature of the ball pin 1 can be regulated.
- a valve can be connected upstream for regulation.
- the filter 10 filters contaminants from the fluid. Thus, the impurities cannot clog the element 8, which extends maintenance intervals.
- the ball pin 1 When using the ball pin 1 in factory buildings, the ball pin 1 can be flowed through by an existing machine fan with air. Alternatively, the ball pin 1 can be connected to an existing compressed air system. This means that no additional peripherals are required, apart from a connection from ball pin 1 to the existing compressed air system. The ball pin 1 can replace a previously used ball pin and is ready for use in just a few simple steps.

Description
Die vorliegende Erfindung betrifft einen Kugelbolzen, insbesondre in einer Musteranordnung einer Kettenwirkmaschine, mit einem ersten Ende, das zumindest einen Teil einer Kugelform aufweist, einem zweiten Ende und einem Abschnitt zwischen dem ersten Ende und dem zweiten Ende, wobei mindesten ein Teil des Kugelbolzens einen Hohlraum aufweist, der durch mindestens einen Kanal mit einer äußeren Umfangsfläche fluidisch verbunden ist.The present invention relates to a ball stud, particularly in a pattern assembly of a warp knitting machine, having a first end having at least part of a spherical shape, a second end and a portion between the first end and the second end, at least part of the ball stud having a cavity having, which is fluidly connected by at least one channel with an outer peripheral surface.
Ein Einsatzbereich der vorliegenden Erfindung ist im Bereich einer Kettenwirkmaschine zwischen einer Legebarre und einer Musteranordnung. Hier weisen bisherige Kugelbolzen Öl-Temperiersysteme auf, bei denen Öl über den Kugelbolzen fließt. Diese Systeme sind wartungsintensiv, weil das Öl Staub oder sonstige Verunreinigungen aufnimmt und diese durch Leitungen weiterfördert. Besonders in einer staubintensiven Umgebung, wie einer Textilverarbeitung, sind Öl-Temperiersysteme durch den hohen Staubanteil sehr anfällig für Verunreinigungen. Diese bleiben meist an besonders schwer zugänglichen Stellen hängen und verstopfen nach einer gewissen Zeit die Leitungen. Die Verunreinigungen müssen im Rahmen einer Wartung entfernt werden. Dies ist nicht nur zeitintensiv, sondern auch mit einem großen Reinigungsaufwand verbunden.One area of application of the present invention is in the area of a warp knitting machine between a guide bar and a pattern arrangement. Here, previous ball pins have oil temperature control systems in which oil flows over the ball pin. These systems are maintenance-intensive because the oil absorbs dust or other contaminants and transports them through pipes. Especially in a dusty environment, such as textile processing, oil temperature control systems are very susceptible to contamination due to the high dust content. These usually get caught in places that are particularly difficult to access and clog the lines after a certain time. The contamination must be removed as part of maintenance. This is not only time-consuming, but also involves a great deal of cleaning work.
Die der Erfindung zugrundeliegende Aufgabe ist, den Einstellaufwand der Kettenwirkmaschine und den Wartungsaufwand eines Kugelbolzens zu reduzieren.The object on which the invention is based is to reduce the adjustment effort of the warp knitting machine and the maintenance effort of a ball pin.
Diese Aufgabe wird dadurch gelöst, dass ein Element, das aus wärmeleitfähigem Material besteht, den Abschnitt umgibt.This object is achieved in that an element made of thermally conductive material surrounds the section.
Durch das Element wird eine Oberfläche des Kugelbolzens vergrößert. Eine große Oberfläche kann mehr Wärme an die Umgebung abgeben als eine kleine Oberfläche. Dadurch kann man eine gleichmäßige Temperatur des Kugelbolzens erreichen. Die gleichmäßige Temperatur ermöglicht eine relativ genaue Einhaltung von Toleranzen. Durch die genaue Einhaltung von Toleranzen wird eine Zerstörung oder ein Verschleiß des Bolzens vermieden, wodurch die Prozesssicherheit des Wirkens erhöht wird.A surface of the ball pin is enlarged by the element. A large surface can give off more heat to the environment than a small one Surface. This allows you to achieve an even temperature of the ball pin. The uniform temperature enables relatively precise compliance with tolerances. Exact adherence to tolerances prevents the bolt from being destroyed or worn out, which increases the reliability of the knitting process.
Vorzugsweise ist der Kanal in radialer Richtung angeordnet. Eine Fertigung des radial angeordneten Kanals ist mit geringem Aufwand verbunden. Weiterhin werden Kugelbolzen meist als rotationssymmetrische Bauteile ausgeführt, sodass der Hohlraum meist als eine Bohrung ausgeführt ist, wobei eine Achse der Bohrung mit einer Achse des Kugelbolzens übereinstimmt. Der radial angeordnete Kanal garantiert somit die Verbindung zwischen dem Hohlraum und der äußeren Umfangsfläche.The channel is preferably arranged in the radial direction. Manufacturing the radially arranged channel involves little effort. Furthermore, ball pins are usually designed as rotationally symmetrical components, so that the cavity is usually designed as a bore, with an axis of the bore coinciding with an axis of the ball pin. The radially arranged channel thus guarantees the connection between the cavity and the outer peripheral surface.
Vorzugsweise sind jeweils zwei Kanäle diametral angeordnet. Diese Anordnung ermöglicht, dass mit einer Bohrung zwei Kanäle, ein Kanalpaar, gefertigt werden kann, was die Fertigung des Kugelbolzens wirtschaftlich macht.Two channels are preferably arranged diametrically in each case. This arrangement allows two channels, a pair of channels, to be manufactured with one bore, which makes the production of the ball pin economical.
Vorzugsweise sind Achsen der Kanäle parallel zueinander. Dies ermöglicht die Fertigung des Kugelbolzens und der Kanäle mit wenigen Umspannungsvorgängen. Eine Umspannung des Kugelbolzens benötigt Zeit und verursacht dadurch Kosten. Diese Kosten können durch parallele Kanäle eingespart werden. Vorzugsweise weist der Abschnitt ein oder mehr Fluidleitelemente zwischen der äußeren Umfangsfläche und dem Element auf. Das Fluidleitelement lässt ein durch den Hohlraum und den Kanal fließendes Fluid gezielt auf das Element treffen. Dadurch wird ein Stau des Fluides verhindert und eine Wärmeabfuhr aus dem Kugelbolzen gewährleistet. Weiterhin entsteht durch das Fluidleitelement ein Abstand zwischen dem Kanal und dem Element, welcher wiederum förderlich für eine Verteilung des Fluides ist. Die Verteilung ermöglicht eine größere Wärmeabfuhr, was die Temperatur gleichmäßig hält.Preferably, axes of the channels are parallel to each other. This enables the ball pin and the channels to be manufactured with just a few reclamping processes. Re-clamping the ball pin takes time and thus causes costs. These costs can be saved by using parallel channels. Preferably, the section has one or more fluid guide elements between the outer peripheral surface and the element. The fluid guide element allows a fluid flowing through the cavity and the channel to strike the element in a targeted manner. This prevents the fluid from accumulating and ensures that heat is dissipated from the ball stud. Furthermore, the fluid guide element creates a distance between the channel and the element, which in turn is beneficial for a distribution of the fluid. The distribution allows for greater heat dissipation, which keeps the temperature even.
Vorzugsweise sind die Fluidleitelemente ringförmig ausgebildet. Ringförmige Fluidleitelemente können mittels Drehmaschinen hergestellt werden, was im Wesentlichen geringe Kosten zur Folge hat. Weiterhin wird das Element durch ringförmige Fluidleitelemente in Sektionen unterteilt, die gegebenenfalls weiter angepasst werden können.Preferably, the fluid guide elements are ring-shaped. Annular fluid guide elements can be manufactured using lathes, resulting in substantially low costs. Furthermore, the element is divided into sections by ring-shaped fluid guide elements, which can be further adjusted if necessary.
Vorzugsweise ist ein Fluidleitelement zwischen benachbarten Kanälen angeordnet. Dadurch ist das Fluidleitelement nicht im Konflikt mit Kanälen und stört die Funktion der Kanäle somit nicht. Weiterhin wird dadurch eine Wärmeübertragung zwischen dem Kugelbolzen und dem Element hergestellt. Die Fluidleitelemente teilen jedem Kanal oder jedem Kanalpaar eine Sektion zu, die den Bedürfnissen entsprechend angepasst werden kann.A fluid guide element is preferably arranged between adjacent channels. As a result, the fluid guide element does not conflict with channels and thus does not interfere with the function of the channels. Furthermore, this creates heat transfer between the ball stud and the element. The fluid directing elements allocate a section to each channel or pair of channels, which can be adjusted according to needs.
Das Element weist eine fluiddurchlässige Struktur auf. Somit kann Fluid ausgehend von dem Hohlraum durch den Kanal und das Element strömen. Während sich das Fluid mit Oberflächen des Kugelbolzens und dem Element in Kontakt befindet, nimmt es Wärme auf und fördert diese nach außen. Die fluiddurchlässige Struktur vergrößert die Oberfläche, mit der das Fluid in Kontakt steht und somit die Oberfläche über die das Fluid Wärme aufnehmen kann. Somit wird die Wärmeabfuhr aus dem Kugelbolzen verbessert.The element has a fluid-permeable structure. Thus, fluid can flow through the channel and the element from the cavity. While the fluid is in contact with surfaces of the ball stud and element, it absorbs heat and expels it to the outside. The fluid-permeable structure increases the surface area with which the fluid is in contact and thus the surface area over which the fluid can absorb heat. This improves heat dissipation from the ball stud.
Vorzugsweise ist das Element zumindest teilweise porös. Poröse Elemente weisen eine große Oberfläche im Verhältnis zu ihrem Volumen auf. Ein großes Oberflächen - zu Volumenverhältnis ergibt eine große Oberfläche, die zur Wärmeübertragung an das Fluid dient, ohne dass das Element bei einem vorgegebenen Bauraum zu voluminös ausgebildet sein muss. Das Fluid kann dementsprechend mehr Wärme aufnehmen und diese mit sich nehmen.Preferably the element is at least partially porous. Porous elements have a large surface area in relation to their volume. A large surface area to volume ratio results in a large surface area, which is used for heat transfer to the fluid, without the element having to be designed too voluminous for a given installation space. Accordingly, the fluid can absorb more heat and take it with it.
Vorzugsweise ist das Element als Sinterelement ausgebildet. Durch ein Sinterverfahren kann das Element passgenau produziert werden. Weiterhin kann das Sinterverfahren eine Porosität gezielt herstellen, sodass das Element verschiedene Porositäten aufweisen kann. Die Porositäten können entsprechend eines Fluidverlaufs angepasst werden, um eine optimale Wärmeabfuhr zu gewährleisten.The element is preferably designed as a sintered element. The element can be produced with a precise fit using a sintering process. Furthermore, the sintering process can produce a specific porosity, so that the element can have different porosities. The porosities can be adjusted according to a fluid flow to ensure optimal heat dissipation.
Vorzugsweise ist das Element formschlüssig mit dem Abschnitt verbunden. Durch einen Formschluss wird eine Wärmeübertragung aus dem Kugelbolzen in das Element garantiert. Weiterhin werden keine weiteren Befestigungsmittel zu einer Montage oder Demontage benötigt. Dies senkt die Wartungskosten bei gleichzeitiger Verbesserung eines Wärmeaustausches zwischen Element und Kugelbolzen. Zur Verbesserung der Wärmeübertragung kann man eine Wärmeleitpaste verwenden.The element is preferably connected to the section in a form-fitting manner. A positive fit guarantees heat transfer from the ball pin to the element. Furthermore, no further fasteners are required for assembly or disassembly. This reduces maintenance costs while improving heat exchange between the element and ball stud. A thermal compound can be used to improve heat transfer.
Vorzugsweise weist der Kugelbolzen einen Strömungsweg durch den Hohlraum, die Kanäle und das Element auf. Der Kugelbolzen wird von dem Hohlraum entlang der Kanäle und durch das Element durchströmt, dadurch wird das Fluid von innen nach außen durch den Kugelbolzen befördert. Dies bewirkt, dass ein Druckgefälle von dem Hohlraum nach außen entsteht. Dadurch wird verhindert, dass Schmutz, Staub, Verunreinigungen oder dergleichen in den Kugelbolzen gelangen. Dadurch wird die Wartung einfach.Preferably, the ball stud has a flow path through the cavity, channels and element. The ball stud is traversed by the cavity along the channels and through the element, thereby moving the fluid from the inside to the outside through the ball stud. This causes a pressure drop from the cavity to the outside. This prevents dirt, dust, impurities or the like from getting into the ball stud. This makes maintenance easy.
Vorzugsweise ist in dem Strömungsweg eine Filteranordnung angeordnet. Die Filteranordnung verhindert, dass Schmutz, Staub, Verunreinigungen oder dergleichen in den Kugelbolzen eindringen und das Element verstopfen. Der Filter kann an einer gut zugänglichen Stelle in einer Fluidzuführung zu dem Kugelbolzen, oder direkt in dem Hohlraum des Kugelbolzens angebracht werden. Bei einer normalen geplanten Wartung kann der Filter auf mögliche Verschmutzung untersucht werden und gegebenenfalls notwendige Schritte vorgenommen werden. Dadurch wird eine Verstopfung des Elementes verhindert und der Kugelbolzen wird in einem optimalen Temperaturfenster gehalten.A filter arrangement is preferably arranged in the flow path. The filter assembly prevents dirt, dust, debris or the like from entering the ball stud and clogging the element. The filter can be installed in an easily accessible location in a fluid supply to the ball stud, or directly in the cavity of the ball stud. During normal scheduled maintenance, the filter can be checked for possible contamination and any necessary steps are taken. This prevents the element from clogging and keeps the ball stud within an optimal temperature window.
Vorzugsweise weist der Kugelbolzen einen Fluidanschluss auf, der mit einer Fluidquelle verbunden ist. Durch den Fluidanschluss steht der Kugelbolzen mit einer Fluidquelle in fluidischer Verbindung. Dadurch ist es möglich, dass der Kugelbolzen zwangsweise mit dem Fluid durchströmt wird. Durch eine Zwangsdurchströmung wird eine gleichmäßige Temperatur des Kugelbolzens gewährleistet.Preferably, the ball stud has a fluid port that is connected to a fluid source. The ball stud is in fluid communication with a fluid source through the fluid connection. This makes it possible for the fluid to flow through the ball stud. A forced flow ensures an even temperature of the ball pin.
Vorzugsweise ist das durch die Fluidquelle geförderte Fluid Luft. Somit kann der Kugelbolzen durch einen Nieder-Druck-Erzeuger, wie beispielsweise einen Maschinenlüfter durchströmt werden. Alternativ dazu kann der Kugelbolzen an einen Druckluftanschluss angeschlossen werden. Es ist keine weitere Peripherie notwendig. Somit bleiben die Anschaffungskosten gering.Preferably, the fluid conveyed by the fluid source is air. Thus, the ball pin can be flowed through by a low-pressure generator, such as a machine fan. Alternatively, the ball stud can be connected to a compressed air connection. No additional peripherals are required. Thus, the acquisition costs remain low.

Der Abschnitt 4 weist Kanäle 5 und Fluidleitelemente 6 auf. Fluidelemente 6 sind auf einer äußeren Umfangsfläche 7 angeordnet. Weiterhin ist ein Element 8 dargestellt. Das erste Ende 2 steht mit einem passendem, nicht dargestellten, Gegenstück in Verbindung. Das zweite Ende 3 weist Befestigungsmöglichkeiten, beispielsweise ein Gewinde oder dergleichen, auf um den Kugelbolzen 1 zu montieren.The section 4 has
Das Element 8 kann durch einen Sinterprozess hergestellt werden. Der Sinterprozess kann eine fluiddurchlässige Struktur des Elementes 8 realisieren. Weiterhin ist durch den Sinterprozess auch eine Produktion von porösen Elementen möglich. Das Element 8 kann örtlich begrenzte fluiddurchlässige Strukturen oder poröse Strukturen aufweisen. Der Sinterprozess kann solche Strukturen realisieren.The
Durch den Hohlraum 9 wird ein nicht dargestelltes Fluid entlang der Pfeilrichtung befördert. In der vorliegenden Ausführungsform tritt Fluid tritt am zweiten Ende 3 des Kugelbolzens 1 in den Hohlraum 9 ein. Von dem Hohlraum 9 strömt das Fluid durch die Kanäle 5 in Richtung der äußeren Umfangsfläche 7, um dort schließlich durch die Fluidleitelemente 6 geleitet das Element 8 zu durchströmen. Während das Fluid mit dem Kugelbolzen 1 oder dem Element 8 in Kontakt steht, nimmt das Fluid Wärme des Kugelbolzens 1 auf und transportiert diese nach außen. Durch das Element 8 wird eine zur Wärmeabfuhr genutzte Oberfläche um ein Vielfaches vergrößert, was einer Wärmeübertragung vom Kugelbolzen 1 auf das Fluid zugutekommt. Je nach Menge des durchströmenden Fluides kann die Temperatur des Kugelbolzens 1 reguliert werden. Für eine Regulierung kann ein Ventil vorgeschaltet werden. Der Filter 10 filtert Verunreinigungen aus dem Fluid. Somit können die Verunreinigungen das Element 8 nicht verstopfen, was Wartungsintervalle verlängert.A fluid, not shown, is conveyed through the
Bei Verwendung des Kugelbolzens 1 in Fabrikhallen kann der Kugelbolzen 1 durch einen vorhandenen Maschinenlüfter mit Luft durchströmt werden. Alternativ dazu kann der Kugelbolzen 1 an ein vorhandenes Druckluftsystem angeschlossen werden. Somit ist keine weitere Peripherie notwendig, bis auf eine Verbindung vom Kugelbolzen 1 zum vorhandenen Druckluftsystem. Der Kugelbolzen 1 kann einen bisher verwendeten Kugelbolzen ersetzen und ist mit einigen wenigen Handgriffen einsatzbereit.When using the
Durch eine Temperierung des Kugelbolzens 1 wird überschüssige Wärme konsequent abgeführt und somit bleibt der Kugelbolzen 1 in einem definierten Toleranzbereich und Temperaturbereich. Entsprechend wird die Reibtemperatur gering gehalten, wodurch eine Zerstörung und oder Verschleiß der Reibpartner vermieden wird Dadurch können die Wartungsintervalle verlängert werden. Weiterhin kann eine Maschine, bei der einen solchen Kugelbolzen 1 eingesetzt wird genauer eingestellt werden, was wiederum den Verschleiß von anderen Bauteilen reduziert.By controlling the temperature of the
