Abstract

Insbesondere, wenn horizontal angeordnete und wirkende Hydraulik- und/oder Pneumatikzylinder einerseits aufgrund beispielsweise eines erforderlichen großen Hubweges lange Baulänge aufweisen, andererseits aber aufgrund vergleichsweise geringer aufzubringender Druck- bzw. Zugkräfte vergleichsweise kleine Durchmesser aufweisen können, neigen solche Zylinder aufgrund der auf sie einwirkenden Schwerkraft sowie unter Last zur Durchbiegung. In der Praxis sind dadurch solchen Zylindern in ihrem Durchmesser Untergrenzen vorgegeben, die die für die aufzubringende Druck- bzw. Zugkraft ansonsten erforderliche Untergrenze deutlich übersteigen. Mit anderen Worten müssen in solchen Fällen die Hydraulik- und/oder Pneumatikzylinder überdimensioniert ausgelegt werden, was zu erhöhten Kosten führt. Neben den erhöhten Kosten muss ein erhöhtes Gewicht der überdimensioniert ausgelegten Zylinder in Kauf genommen werden wie auch eine für den Betrieb erforderliche höhere benötigte Ölmenge im Fall von Hydraulikzylindern. Auch die letztgenannten Aspekte wirken sich schließlich kostensteigernd aus.In particular, when horizontally disposed and acting hydraulic and / or pneumatic cylinders on the one hand due to, for example, a required long stroke long length, but on the other hand due to comparatively low applied pressure or tensile forces may have comparatively small diameter, such cylinders tend due to the force acting on them gravity as well as under load to the deflection. In practice, such cylinders are given in their lower diameter limits that exceed the otherwise required for the applied pressure or tensile force lower limit significantly. In other words, in such cases, the hydraulic and / or pneumatic cylinders must be designed oversized, which leads to increased costs. In addition to the increased costs, an increased weight of the oversized designed cylinder must be taken into account as well as a required for the operation higher required amount of oil in the case of hydraulic cylinders. The latter aspects also ultimately increase costs.

Um hier Abhilfe zu schaffen, wird mit der Erfindung eine Lagervorrichtung zum Lagern eines horizontal angeordneten Hydraulik- und/oder Pneumatikzylinders vorgeschlagen in Form einer sich über im wesentlichen die gesamte Länge des Zylinders erstreckenden, in ihrer Breite im wesentlichen der Breite des Zylinders entsprechenden, einen Auflageboden und zwei Seitenwände aufweisenden, biegsteifen Lagerwanne (2), die wenigstens an ihren beiden Längsenden Pufferauflagen (5) zum abgepufferten Auflagern des Zylinders aufweist.

To remedy this situation, the invention proposes a bearing device for supporting a horizontally arranged hydraulic and / or pneumatic cylinder in the form of a substantially over the entire length of the cylinder extending in width substantially corresponding to the width of the cylinder, one Support base and two side walls having bending-resistant bearing trough (2) which has at least at its two longitudinal ends buffer pads (5) for buffered bearing of the cylinder.
