Abstract
Vorgeschlagen ist ein Riemenspanner (1) zum Anbau an einen Generator eines Nebenaggregatetriebs einer Brennkraftmaschine, umfassend: – ein auf dem Generator gelagertes Spannergehäuse (7) mit einer kreisbogenförmigen Kavität (19), – zwei Spannrollen (2, 3), die den Riemen in dessen Umlaufrichtung vor und hinter der Riemenscheibe des Generators mit Vorspannkraft beaufschlagen, – eine die Vorspannkraft erzeugende Bogenfeder (5, 6), die in der Kavität aufgenommen ist, – einen kreisbogenförmigen Spannhebel (8), der in der Ebene des Kreisbogens beweglich in der Kavität gelagert ist und der an einem Ende durch die Kraft der Bogenfeder beaufschlagt ist und am anderen Ende eine der Spannrollen lagert, – und als Lagerung des Spannhebels ein am Umfang mehrteiliges Gleitlager (21), dessen Lagerteile (25, 26) am Eingang der Kavität im Spannergehäuse eingesetzt sind. Das Gleitlager soll den Spannhebel dichtend umschließen.A belt tensioner (1) for attachment to a generator of an auxiliary unit drive of an internal combustion engine is proposed, comprising: - a tensioner housing (7) mounted on the generator with an arcuate cavity (19), - two tensioning rollers (2, 3) which hold the belt in apply prestressing force to its direction of rotation in front of and behind the belt pulley of the generator, - an arc spring (5, 6) which generates the prestressing force and which is accommodated in the cavity, - an arcuate clamping lever (8), which is movable in the plane of the arc in the cavity and which is acted upon by the force of the bow spring at one end and one of the tensioning rollers is supported at the other end, - and a sliding bearing (21) which is multi-part on the circumference as a bearing for the tensioning lever and whose bearing parts (25, 26) at the entrance of the cavity in Tensioner housings are used. The plain bearing should enclose the clamping lever in a sealing manner.
Description
Die Erfindung betrifft einen Riemenspanner zum Anbau an einen Generator eines Nebenaggregatetriebs einer Brennkraftmaschine, umfassend:
- – ein auf dem Generator gelagertes Spannergehäuse mit einer kreisbogenförmigen Kavität,
- – zwei Spannrollen, die den Riemen in dessen Umlaufrichtung vor und hinter der Riemenscheibe des Generators mit Vorspannkraft beaufschlagen,
- – eine die Vorspannkraft erzeugende Bogenfeder, die in der Kavität aufgenommen ist,
- – einen kreisbogenförmigen Spannhebel, der in der Ebene des Kreisbogens beweglich in der Kavität gelagert ist und der an einem Ende durch die Kraft der Bogenfeder beaufschlagt ist und am anderen Ende eine der Spannrollen lagert,
- – und als Lagerung des Spannhebels ein am Umfang mehrteiliges Gleitlager, dessen Lagerteile am Eingang der Kavität im Spannergehäuse eingesetzt sind.
- A tensioner housing mounted on the generator and having a circular arc-shaped cavity,
- Two tension rollers, which bias the belt in the direction of rotation in front of and behind the pulley of the generator,
- A preload generating bow spring received in the cavity,
- A circular-arc clamping lever, which is mounted in the plane of the circular arc movable in the cavity and which is acted upon at one end by the force of the bow spring and at the other end one of the tension rollers,
- - And as a storage of the clamping lever on a perimeter multi-part sliding bearing, the bearing parts are used at the entrance of the cavity in the tensioner housing.
Hintergrund der ErfindungBackground of the invention

Aufgabe der ErfindungObject of the invention
Ausgehend hiervon liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Riemenspanner der eingangs genannten Art konstruktiv zu verbessern.Proceeding from this, the present invention seeks to constructively improve a belt tensioner of the type mentioned.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung hierfür ergibt sich aus den Merkmalen des Anspruchs 1. Demnach soll das Gleitlager den Spannhebel dichtend umschließen. Die erfindungsgemäße Funktionsintegration der Dichtung in das Gleitlager verhindert nicht nur ein Eindringen von Kontamination, wie Schmutzpartikel oder Spritzwasser in die Kavität hinein, sondern verhindert auch den Austritt von einer gegebenenfalls vorhandenen Befettung der Bogenfeder.The solution to this arises from the features of
In bevorzugter Ausgestaltung soll das Gleitlager den Spannhebel mit den Dichtungsteilen einer mehrteiligen Dichtung umschließen. Diese kann eine elastomere Lippendichtung mit zumindest einer Dichtlippe sein, die vollumfänglich am Spannhebel anliegt. In a preferred embodiment, the sliding bearing is intended to enclose the tensioning lever with the sealing parts of a multi-part seal. This may be an elastomeric lip seal with at least one sealing lip, which rests fully on the clamping lever.
