Abstract

Drehantrieb (1), insbesondere pneumatischer Drehantrieb, mit einem durch einen Gehäusedeckel (2) verschlossenen Gehäuse (3), und einem innerhalb des Gehäuses (3) gegen die Wirkung ein oder mehrerer Federelemente (4) verschieblich gelagerten Kolben (5), mit einer im Gehäusedeckel (2) drehbar gelagerten Welle (6), die zumindest innerhalb des Gehäuses (3) als Spindelwelle (7) mit einem Außengewinde (8) ausgebildet ist, wobei die Spindelwelle (7) in eine in dem Kolben (5) angeordnete Spindelmutter (9) eingreift.Rotary drive (1), in particular pneumatic rotary drive, with one by one Housing cover (2) closed housing (3), and one inside the housing (3) against the action of one or more spring elements (4) slidably mounted Piston (5), with a shaft (6) rotatably mounted in the housing cover (2), which at least inside the housing (3) is designed as a spindle shaft (7) with an external thread (8), wherein the spindle shaft (7) engages in a spindle nut (9) arranged in the piston (5).

Es soll ein Drehantrieb (1) geschaffen werden, der einfach und funktionsgerecht aufgebaut ist, und in wartungstechnischer Hinsicht allen Anforderungen genügt.A rotary drive (1) is to be created which is simple and functional is built, and meets all requirements in terms of maintenance.

Hierzu wird vorgeschlagen, daß der Gehäusedeckel (2) an dem Gehäuse (3) lösbar fixiert ist und mit dem Kolben (5) in Federspannung haltender Verbindung steht. Folglich sind Gehäuse (3) und Gehäusedeckel (2) nicht mehr miteinander verschweißt, vielmehr läßt sich der Gehäusedeckel (2) im Zuge der Wartung vom Gehäuse (3) trennen. Damit wird der Gehäuseinnenraum frei zugänglich und der Drehantrieb (1) kann vollständig oder nahezu vollständig zerlegt werden.

Figure 00000001
For this purpose, it is proposed that the housing cover (2) is releasably fixed to the housing (3) and is connected to the piston (5) in a spring-holding connection. As a result, the housing (3) and the housing cover (2) are no longer welded to one another, rather the housing cover (2) can be separated from the housing (3) during maintenance. The interior of the housing is thus freely accessible and the rotary drive (1) can be completely or almost completely dismantled.
