Coupling flanges - Import export

RINGFEDER® Flange Couplings are the better alternative to press fits. Neither additional components such as keyways or wedges, nor a warming of the outer section and cooling of the inner section are required. The flange coupling is simply pushed onto the shaft and fastened so it is frictionally engaged by tightening the screws in the shrink disc. They transfer torque and bending moments as well as axial and radial forces. Advantages Strong connection with high torque capacity Easy assembly and disassembly Backlash-free shaft hub connection High level of true running accuracy Applications Mining companies Plant manufacturers Gearbox manufacturers Designs Version A Shrink Discs with hexagon head screws HM = Centering outside HF = Centering inside Version B Shrink Discs with hexagon socket head cap screws HM = Centering outside HF = Centering inside Explanations to tables Basic dimensions when screws are not tightened d w1 = Solid shaft diameter d w2 = Solid shaft diameter A =...

PDR - Side-entry agitator Side-entry agitator for mixing below liquid surface. The PDR is a simple side-entry-agitator for mixing below the liquid surface. The PDR is recommended for applications where low viscous liquids are mixed turbulently in high tanks and where a top-entry mixer would be too heavy due to its shaft length and –diameter. The sealing between the agitator and the vessel is done by means of a single-acting, internal mechanical seal which is lubricated by the mixing product or an additional fluid The agitator shaft is connected to the drive directly with a flange coupling inside the seal housing. By default, this agitator series is supplied with marine type propellers. Other mixing elements according to the mixing task upon request. Solutions correspond to those of the SPR, additionally mechanical seal in sealing housing. Other solutions for this series upon request.

SPR - Standard-propeller-agitator The direct driven agitator SPR is Geppert Rührtechnik’s solution for all industrial mixing tasks that demand a turbulent mixing with high peripheral speeds. It is driven by a three-phase-motor with poles between 2 and 8 as well as drive ratings between 0.25 kW and 75.0 kW. The SPR could also be equipped with a frequency inverter upon request (up to 7.5 kW). The agitator shaft is directly connected at the shaft journal of the drive via sleeve or flange coupling. Solutions with quick-change or precisions-change coupling are also feasible for lower drive ratings of up to 3.0 kW. The standard agitator element is a propeller. Other mixing elements according to the mixing task upon request. The SPR can be mounted as a stationary unit or – at a weight of up to 25 kg – it can also be mounted directly onto the open tank via a vessel clamp Up to motor size 112, all SPR series agitators can also be provided with reinforced shaft.

Combination one-part/multi-part with VKR buffers - Claw ring can be pushed back for checking the direction of rotation The TSCHAN ® TNB BHDV coupling is a torsionally flexible, puncture proof claw coupling. It compensates for angular, radial and axial shaft misalignments within defined limits. The coupling transmits torque through elastic buffers loaded in compression. These buffers come in perbunan (PB) or polyurethane (Vk), as a standard VkR. These elastic buffers dampen shocks and torsional vibrations and are resistant to oil. Buffers made of perbunan are electrically conductive. One of the coupling halves consists of a flange hub to which a claw ring is bolted. When the claw ring is removed, it is easily possible to check the rotational direction of the drive. The coupling is suitable for use in every direction of rotation and installation position. TSCHAN ®-TNB Type BHDV For short shaft distances, a combination of an one one-part design and a multi-part design coupling hub...
