Description
Kugelbüchsen sind hinlänglich bekannt. Sie dienen der längsbeweglichen Lagerung von Wellen. Eine derartige Kugelbüche war beispielsweise aus
Aufgabe der vorliegenden Erfindung war es, eine Kugelbüchse gemäß dem Oberbegriff des Anspruchs 1 anzugeben, die eine einwandfreie Dichtung bereitstellt. Object of the present invention was to provide a ball bushing according to the preamble of claim 1, which provides a perfect seal.
Erfindungsgemäß wurde diese Aufgabe durch die Kugelbüchse gemäß Anspruch 1 gelöst. Zweckdienliche Weiterbildungen sind in den abhängigen Ansprüchen angegeben.According to the invention this object has been achieved by the ball bushing according to claim 1. Expedient developments are specified in the dependent claims.
Die erfindungsgemäße Kugelbüchse zur längsverschieblichen Lagerung von Wellen weist mehrere über den Umfang verteilt angeordnete endlose Umlaufkanäle für Kugeln auf. Jeder Umlaufkanal weist einen entlang der Längsachse der Kugelbüchse angeordneten Lastabschnitt, einen Rücklaufabschnitt sowie zwei den Lastabschnitt mit dem Rücklaufabschnitt endlos verbindende Umlenkabschnitte auf. Dadurch, dass am Außenumfang der Kugelbüchse an deren beiden axialen Enden jeweils eine umlaufende Dichtung angeordnet ist, kann die Kugelbüchse ohne weitere Maßnahmen beispielsweise in eine Gehäusebohrung eines Gehäuses eingesetzt werden. Weitere Maßnahmen zur Abdichtung des Außenumfangs des Gehäuses sind nicht erforderlich.The ball bush according to the invention for the longitudinally displaceable mounting of shafts has a plurality of circumferentially spaced endless circulation channels for balls. Each circulation channel has a load section arranged along the longitudinal axis of the ball bushing, a return section and two deflection sections connecting the load section with the return section in an endless manner. Characterized in that on the outer circumference of the ball bush at the two axial ends of each a circumferential seal is arranged, the ball bushing can be used without further measures, for example, in a housing bore of a housing. Other measures for sealing the outer circumference of the housing are not required.
Die Kugelbüchse kann an ihren beiden axialen Enden je eine umlaufende Nut aufweist, in der die als Dichtring ausgebildete Dichtung angeordnet ist. Es können handelsübliche O-Ringe eingesetzt werden. Zweckmäßigerweise sind die Nuttiefe und die Nutbreite so bemessen und auf den vorgesehen Dichtring abgestimmt, dass der eingesetzte Dichtring einen Außendurchmesser aufweist, der größer als der Außendurchmesser der Kugelbüchse ist. Wenn diese Kugelbüchse in eine vorbereitete Gehäusebohrung eingesetzt wird, kommt der Dichtring zur Anlage an die Wandung der Gehäusebohrung und dichtet auf diese Weise den Außenumfang der Kugelbüchse zur Umgebung außerhalb der Gehäusebohrung ab.The ball bush can each have a circumferential groove at its two axial ends, in which the seal designed as a sealing ring is arranged. Commercially available O-rings can be used. Conveniently, the groove depth and the groove width are dimensioned and matched to the intended sealing ring, that the inserted sealing ring has an outer diameter which is larger than the outer diameter of the ball bushing. When this ball bushing is inserted into a prepared housing bore, the sealing ring comes to rest on the wall of the housing bore and seals in this way the outer circumference of the ball bush to the environment outside the housing bore.
Alternativ zu den Dichtringen kann es auch vorteilhaft sein, an beiden axialen Enden der Kugelbüchse jeweils einen Dichtring mit einer umlaufenden Dichtlippe aufzuspritzen. Die Dichtlippe kann ebenso wie der zuvor beschriebene Dichtring dichtend an der Wandung der Gehäusebohrung anliegen.As an alternative to the sealing rings, it may also be advantageous to inject a sealing ring with a circumferential sealing lip at both axial ends of the ball bushing. The sealing lip can, like the sealing ring described above, bear sealingly against the wall of the housing bore.
Die Kugelbüchse kann eine Hülse aufweisen, in der die Kugelumläufe angeordnet sind, wobei die Dichtungen am Außenumfang der Hülse angeordnet sind. Demzufolge können die beschriebenen umlaufenden Nuten an der Hülse ausgebildet sein. Alternativ können die mit den Dichtlippen versehenen Dichtungen auf den Außenumfang der Hülse aufgespritzt sein.The ball bushing may comprise a sleeve in which the ball circulations are arranged, wherein the seals are arranged on the outer circumference of the sleeve. As a result, the described circumferential grooves can be formed on the sleeve. Alternatively, the seals provided with the sealing lips can be sprayed onto the outer circumference of the sleeve.
Ein anderer zweckmäßiger Typ von Kugelbüchsen kann mehrere über den Umfang verteilt angeordnete Segmente zur Bildung der Umlaufkanäle aufweisen, wobei alle Segmente durch zwei an beiden axialen Enden der Segmente angeordnete Ringe zusammengehalten sind. In diesem Fall können die Dichtungen am Außenumfang der beiden Ringe angeordnet sein, also als Dichtringe ausgebildet sein, die in umlaufende Nuten der beiden Ringe eingesetzt sind, oder auf den Außenumfang dieser Ringe aufgespritzt sein.Another convenient type of ball bushings may include a plurality of circumferentially spaced apart segments to form the circulation passages, all of the segments being held together by two rings disposed at both axial ends of the segments. In this case, the seals can be arranged on the outer circumference of the two rings, so be designed as sealing rings, which are inserted into circumferential grooves of the two rings, or be sprayed onto the outer circumference of these rings.
Es ist vorteilhaft, eine Linearlageranordnung mit einer erdfindungsgemäßen Kugelbüchse zu versehen. Diese Linearlageranordnung weist ein Gehäuse auf, in dessen Gehäusebohrung die Kugelbüchse gelagert ist, wobei die Dichtringe oder die Dichtlippen der Dichtungen an der Wandung der Gehäusebohrung dichtend anliegen.It is advantageous to provide a linear bearing assembly with a ball socket according to the invention. This linear bearing arrangement has a housing, in the housing bore of the ball bush is mounted, wherein the sealing rings or the sealing lips of the seals on the wall of the housing bore sealingly.
Nachstehend wird die Erfindung anhand eines in einer Figur abgebildeten Ausführungsbeispieles näher erläutert. The invention will be explained in more detail with reference to an embodiment shown in a figure.
