Shaft couplings - Import export

Shaft Couplings RfN 5071 Standard series – this range is the most popular, being used in most applications. Characteristics Shrink discs are the modern method for creating a mechanical shrink fit. The shrink disc consists of either one or two thrust rings with tapered bores and a mating tapered inner ring. By tightening locking screws the thrust rings are drawn together compressing the inner ring and applying pressure to the outside of the hub clamping it to the shaft. Being positioned around the hub there is only one interface transmitting the loads giving the shrink disc method distinct advantages such as offering the possibility of very concentric and well balanced connections that are suited to high speed applications. Traditional shrink fits require complicated calculations, close machining tolerances and fine surface finishes, they also need considerable effort with mounting and removal. The Shrink Disc connection has none of these disadvantages and is better than any of...

The tote tank mixers CR-M are designed for operation on stainless steel containers with filling openings of DN 400 mm and mixing volumes from 400 l up to 1,500 l. Depending on the viscosity of the mixing material, CR-Ms with fast running or gear reduced drives are available. The agitator shafts are connected to the drive shafts with sleeve couplings or borne within the gear’s hollow shaft (worm gear). The agitator shafts are balanced for concentric run after assembly. The mixer is mounted on the container’s manway lid, which is clamped with butterfly screws or a clamp ring. The manway lid is supplied by the container manufacturer or by the customer. The impellers are designed to fit through the filling opening DN 400 when being inserted. The electric container mixers are delivered with on-/off-switches with low-voltage breaker. The electric container mixers can also be supplied with frequency converter drives. All CR-M series mixers can be supplied as follows:

The FRP is Geppert Ruhrtechnik’s fast running pneumatic air mixer that can be directly mounted on 200 l steel drums with a 2“ bung hole. The FRP is mounted onto the drum with a 2” threaded adapter. The agitator is screwed into the bung hole. We do offer one drive especially adapted for low viscous media and one drive especially adapted for medium viscous media of up to 1,000 mPas. The agitator shaft is connected to a bearing shaft within the drum mixer housing by means of a sleeve coupling. This bearing shaft is connected to the drive shaft. Folding propellers are used as agitator elements, which can be inserted into the drum through the 2” bung hole when being folded. As a mobile mixer, the FRP can be delivered as a turn-key machine with a service kit for the lubrication of the compressed air and a noise muffler.
