Abstract (en)

The drive has a longitudinal housing containing (4) a movable drive section (13) as well as a holder (24,25) for attaching the linear drive to a support structure (2). The holder is attached to either one end of the housing (27) by a closed holder wall (33) or at the other end of the housing (26) by a perforated holder wall (32). A seal arrangement (48) is provided for sealing the transfer region (46) between the housing and the holder, where the arrangement consists of sealing rings. The rings are designed so as to have a transfer angle at their sides in cross section which is greater than 90 degrees. The seal ring comprises a corrosion-resistant and non-toxic material.

Abstract (de)

Es wird ein insbesondere für Einsätze in der Lebensmittel- und/oder Medizinindustrie geeigneter Linearantrieb vorgeschlagen. Er verfügt über ein längliches Gehäuse (4), das an einem oder beiden Gehäuse-Endabschnitten (26, 27) mit einem zur Befestigung dienenden Halter (24, 25) versehen ist. Der Halter ist entweder mit einer geschlossenen Haltewand (33) an dem betreffenden Gehäuse-Endabschnitt (27) angesetzt oder mit einer gelochten Haltewand (32) auf den zugeordneten Gehäuse-Endabschnitt (26) aufgesetzt. Zur Abdichtung der Übergangsbereiche (46) zwischen dem Gehäuse (4) und einem jeweiligen Halter (24, 25) sind Dichtringe (47) vorgesehen, deren Außenfläche (52) so gestaltet ist, dass der zwischen ihren beiden Randabschnitten und dem jeweils benachbarten Flächenabschnitt des Gehäuses (4) und des zugeordneten Halters (24, 25) eingeschlossene Übergangswinkel größer als 90° ist. Außerdem besteht jeder Dichtring (47) aus korrosionsbeständigem und nicht-toxischem Material. <IMAGE>
