Description
Die Erfindung betrifft nachgiebig federnde Wellenkupplungen, bei welchen die Kupplungsflansche durch ein ringförmiges, im Querschnitt bogenförmiges Zwischenglied aus Gummi verbunden sind.The invention relates to resilient shaft couplings in which the coupling flanges are connected by an annular, in cross-section arcuate intermediate member made of rubber.
Bei den bisherigen Ausführungen solcher Kupplungen ist das Zwischenglied zwischen dem Kupplungsflansch und dem dazugehörigen Spannring an jeder Kupplungshälfte mit einem ringscheibenförmigen Rand von etwa gleichbleibender Dicke eingespannt, welcher über die ganze radiale Breite des Spannringes reicht und daher an den Stellen, wo die Spannschraiiben den Spannring mit demIn the previous versions of such couplings, the intermediate member is between the coupling flange and the associated clamping ring on each coupling half clamped an annular disc-shaped edge of approximately constant thickness, which extends over the entire radial width of the clamping ring and therefore at the points where the Clamping screws the clamping ring with the
ig Kupplungsflansch verbinden, durchbohrt ist. Weil infolgedessen der lichte Durchmesser der Einspannränder des Zwischengliedes erheblich kleiner ist als der Durchmesser der Spannringe oder des Kupplungsflansches, ist das Einbringen eines dieser Teile in die Höhlung des Zwischengliedes sehr mühsam. Ein weiterer die Haltbarkeit des Zwischengliedes betreffender Nachteil ergibt sich aus dem bei den bisherigen Darstellungen vorliegenden Umstand, daß die Ringscheibenteile des Zwischengliedes beim Austritt aus der Einspannstelle am äußeren Umfang ihre Dicke beibehalten und zwischen den scharfen Umfangskanten der Einspannteile eingequetscht sind.ig connect coupling flange, is pierced. Because as a result, the clear diameter of the clamping edges of the intermediate link is considerable is smaller than the diameter of the clamping rings or the coupling flange, the introduction of one of these parts into the cavity of the pontic very laborious. Another is the durability of the pontic The disadvantage in question arises from the previous representations The fact that the washer parts of the intermediate link when exiting the clamping point maintain their thickness on the outer circumference and between the sharp circumferential edges the clamping parts are squeezed.
Im Betrieb schneiden sich infolgedessen die Umfangskanten in das Zwischenglied ein und zermürben es vorzeitig.As a result, during operation the peripheral edges cut into the intermediate member and wear it down prematurely.
Zur Vermeidung dieser Nachteile erhalten nach der Erfindung die Anschlußränder des Gummizwischengliedes eine wulstartige Verdickung und werden in auf den einander zugekehrten Stirnflächen der Einspannflansche vorgesehenen Ringnuten von einem lichten Durchmesser, welcher erheblich größer als der Lochkreisdurchmesser und nur wenig kleiner als der äußere Flanschdurchmesser ist, leingespannt.To avoid these disadvantages, according to the invention, the terminal edges of the Rubber intermediate link a bead-like thickening and are in on the facing End faces of the clamping flanges provided annular grooves with a clear diameter which is considerably larger than the bolt circle diameter and only slightly smaller than the outer flange diameter is, leashed.
Diese Ausbildung des Zwischengliedes und der Einspannelemente hat noch den Vorteil, daß das Drehmoment an dem größtmöglichen Umfang von den Kupplungshälften auf das Zwischenglied übertragen wird. Nur der verdickte Rand (Wulst) ist eingespannt, an dem Übergang vom Wulst in die scheibenförmigen Teile des Zwischengliedes findet keine Kantenpressung statt.This design of the intermediate link and the clamping elements also has the advantage that the torque to the greatest possible extent from the coupling halves to the Intermediate link is transmitted. Only the thickened edge (bead) is clamped on which There is no edge pressure at the transition from the bead to the disk-shaped parts of the intermediate link instead of.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel in einem radialen Schnitt.The drawing illustrates an embodiment in a radial section.
Auf die Wellenzapfen W1 und W2 sind die Kupplungsscheiben IiZ1 und a2 aufgekeilt. Auf ihre an der Wurzel der Scheibenteller zylindrisch abgedrehten Naben sind Einspannringe O1 und b2 aufgeschoben, welche zweckmäßig den gleichen äußeren Durchmesser wie die Scheibenteller erhalten und wie diese auf den je eine Ringfuge begrenzenden Flächen eine Eindrehunge zum Einspannen der ver-. dickten Wulstränder r erhalten.The clutch disks IiZ 1 and a 2 are keyed onto the shaft journals W 1 and W 2. On their cylindrically trimmed at the root of the disc plate hub gripping rings O 1 and b 2 are pushed, which advantageously have the same outer diameter as the disc plate and how these limiting to a respective annular joint surfaces of a recess e for clamping the past. thick bulges r preserved.
Die lichte Weite der EinspannwulstränderThe clear width of the Einspannwulstränder
ist kleiner als der Außendurchmesser der Scheibenteller. Ähnlich wie Reifendecken auf Radfelgen aufgebracht werden, wird auch hier der Gummiwulstring g erst mit einer Umfangshälfte über den einen Rand gestülpt und mit seinen Wulsträndern so stark exzentrisch zur Kupplungsnabe gelegt, daß die andere Umfangshälfte des einen Wulstrandes ebenfalls über den dazugehörenden Scheibenflansch gestreift werden kann. Die elastische Nachgiebigkeit des Gummiringes gestattet die gleiche Handhabung auch zum Aufbringen des anderen Wulstrandes auf die Gegenscheibe. Es ist sogar möglich, den Gummiring zwischen den bereits eingebauten und im normalen Abstand voneinander ausgerichteten Kupplungsscheiben hindurchzuführen und seine beiden Wulstränder alsdann nacheinander über die beiden Scheibenteller zu streifen, sofern nur der Abstand der Kupplungsscheiben etwas größer als die größte Wanddicke des Gummiringes ist. Hiernach werden die Wulstränder r mittels der Spannschrauben s zwischen den Scheibentellern und den ■^Einspannringen b festgespannt. .is smaller than the outer diameter of the disc plate. Similar to the way tire covers are applied to wheel rims, one half of the circumference of the rubber bead ring g is first placed over one edge and its bead edges are placed so strongly eccentrically to the coupling hub that the other half of the circumference of one bead edge can also be slipped over the associated disc flange. The elastic resilience of the rubber ring allows the same handling to apply the other bead to the counter-disk. It is even possible to pass the rubber ring between the already installed clutch disks, which are aligned at the normal distance from each other, and then to slide its two bead edges one after the other over the two disk plates, provided that the distance between the clutch disks is slightly greater than the greatest wall thickness of the rubber ring. The bead edges r are then clamped between the disc disks and the clamping rings b by means of the clamping screws s. .
