The Invention will now be described with reference to an embodiment with reference explained in detail on the drawing. Show it in schematically:

1 an adapter according to the invention in three-dimensional view;

2a a front view of in 1 embodiment shown;

3 a section through the in 1 embodiment shown; and

4 a rear view of the in 1 shown embodiment.

1 shows an adapter according to the invention 10 in plan view. On a drive side 12 a motor can be connected to the adapter and to an output side 14 of the adapter 10 a gearbox. Another housing part 18 of the adapter 10 is approximately cylindrical shell-shaped and thus forms a central axis. The further housing part 18 has input side a flange 30 on. The flange 30 is designed with a known hole pattern to flanging a motor to the adapter. The output side is at a driven end face of the other housing part 18 an O-ring 19 arranged.

Radially directed inward is on the other housing part 18 disc-like an inner ring 21 formed. The inner ring 21 divides the other housing part in a drive-side and in a driven-side pot-like section. In the output side section is a housing part 16 arranged so that between the housing part 16 and the other housing part 18 a partial volume 26 is included. The partial volume is from an outer wall of the housing part 16 and an inner wall of the further housing part 18 as well as the inner ring limited.

The inner ring 21 has a borehole 42 on which with a threaded hole 44 in a cylinder jacket-shaped housing wall of the housing part 16 corresponds. A screw 46 is passed through the well bore designed as a sink hole and screwed into the threaded hole.

A through hole 22 is through the inner ring 21 and the cylinder jacket-shaped housing wall of the housing part 16 guided. Thus, there is between the input side 12 and the output side 14 a connection. In the through hole 22 is a pressure balance agent 24 arranged in the form of a vent valve. The through hole can also be closed by a stretchable element such as a rubber membrane or a bellows. Likewise, an oil filter is placeable in the through hole.

Is now on the input side 12 a motor connected and on the output side 14 a gear, so is the gearbox via the pressure compensation element 24 can be vented or depressurised. The input side portion of the other housing part 18 is closed by the engine and serves as a pressure compensation volume. Thus load a vent valve on the transmission itself save and possibly exiting a vent valve oil foam is in the other part of the housing 18 captured in interaction with the connected motor or device to be driven. Another advantage arises from the fact that a visible surface of the adapter 10 in the installed state only by the surface of the other housing part 18 is formed. This is advantageous when using a geared motor in an environment with special hygienic requirements.

In the housing part 16 is an adapter shaft 32 with a first camp 36 and a second camp 38 stored. The adapter shaft 32 has input side a coupling element 40 for connecting a motor shaft. The output side is the adapter shaft 32 designed as a solid shaft with feather, so that, for example, a gear pinion is plugged, which then projects into a gear housing. Approximately on the housing part 16 has the adapter shaft 32 a spray disk 50 on. Between housing part 16 and output shaft 32 is a shaft seal 48 arranged.

To increase the pressure compensation volume is in the inner ring 28 introduced a bore. Through the hole is the partial volume 26 with the input side portion of the other housing part 18 connected.

A Surface of the other housing part is ground and electropolished and has a center roughness between about 0.8 microns and about 6.0 microns, in particular between about 1.5 microns and about 2.5 microns. In the installed state with gearbox and motor is only the surface of the other housing part visible from the outside. The design is particularly suitable for applications with special hygienic requirements and facilitates the cleaning of the entire drive.

In a further embodiment, the surface of the further housing part 18 only radii of curvature greater than 3 mm, in particular greater than 6 mm. This allows for easy cleaning, as liquids drain well on the surface. For further improvement, the surface can also be coated with a non-stick coating. The non-stick coating preferably comprises a polymer such as polytetrafluoroethylene.
