General description

The POL PO LY-NOR M® coupling is a torsionally flexible, shear type shaft coupling. It has an axial plug-in design with a unique short s hort over all length. The POLY POLY-NOR -NORM M® can be used in nearly all types of machinery and is ideal for the pump industry. The POLY-NORM® coupling compensates for shaft misalignment of all kinds and safely transmits the torque.

Function/Design

The coupling consists of two hubs, with fingers separated by elastomeric elements. The hubs are assembled blindly plugging the hub fingers into each other axially and the elastomer ring is trapped in a groove between both coupling hubs. The compact POLY-NORM ® coupling transmits torque with the elastomer in compression. Shaft misalignments, vibrations and shock loads are effectively absorbed by the POLY-NORM®. The coupling is maintenance-free and used in general machinery, the pump industry and in compressors. Torques of up to 26,800 Nm are stocked in 17 different sizes and 7 designs. In addition to the standard coupling models, flange drop out center and spacer options are available in many variations.

Explosion-roof use

POLY-NORM® couplings are suitable for the use in drives in hazardous areas. The couplings are certified according to EC Standard St andard 94/9/EC (ATEX 95) and belong to category 2G/2D, are confirmed and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22. Please read our information in the respective Type Examination Certificate and the operating and mounting instructions under www.ktr www.ktr.com. .com.

Variety of Options

The coupling can be adapted to many applications due to the many options that are possible with the building block arrangement. The POLY-NORM ® components of a given model can be mixed and matched with each other to obtain different shaft distances using the same s ame basic component. On request, we can provide customized variations of the POLY-NORM to fit your needs – for example, our POLY-NORM® overload coupling with with RUFLEX RUF LEX® torque limiter. Just ask us! ®

POLY-NORM® Torsionally flexible coupling Coupling selection Selection of the POLY-NORM® coupling meets the DIN 740 part 2 specification specification.. The coupling must be sized such that the coupling rated nominal torque is not exceeded in any operating condition. A comparison must be made between the application torque vs. the rating of the coupling. The selection process for torsionally flexible shaft couplings is described in detail in the ROTEX R OTEX® catalogue which ® can be used for POLY-NORM couplings as well.

Assembly Guidelines

During assembly, the coupling halves must be mounted in a way that the coupling hub faces are flush to the end of the shafts. The alignment of the shafts must be adjusted that radial and the angular misalignments are minimal. The life of the coupling and bearings is extended by precise alignment. Steps must be taken to ensure that the alignment will not change during all operating conditions. Shaft misalignments which cannot be avoided must not exceed the figures figures indicated in the table. Angular and radial misalignments misalignments can occur at the same time but the sum of these misalignments must not exceed the figures set forth in the table above.

General description

REVOLEX® KX is a torsionally flexible, failsafe pin & bush coupling. It can be plugged in axially and is characterized by its short design. In addition, REVOLEX R EVOLEX® KX allows for an easy disassembly of the elastomer rings including the pins while being assembly. Taking Taking into account the transmittable torque, REVOLEX ® KX is based on the POLY-NORM® coupling. The REVOLEX® KX coupling compensates for every kind of shaft misalignment while transmitting the torque safely. s afely.

Operation/Arrangement

The coupling consists of two hubs. The torque is transmitted via the steel pins with their taper elastomer rings. As a result all kinds of shaft misalignment, for example caused by inaccurate alignment of the driving or driven elements, is compensated for reliably and vibrations and shocks are compensated for excellently excellently.. The coupling is maintenance-free and is used in general engineering and the pump industry, conveyor technology, technology, etc. For an optimum adjustment to the different applications, 14-off sizes are available covering torques up to 377.800 Nm. Apart from the standard programme customized solutions are available.

REVOLEX® KX Torsionally flexible pin & bush coupling Coupling selection The selection of the REVOLEX® KX coupling has to be dimensioned in a way that the permissible coupling load is not exceeded with any operating condition. For this purpose a comparison between the loads that arise and the permissible coupling parameters has to be performed. 1

Drives without periodical torsional vibrations

e. g. centrifugal pumps, fans, screw compressors, etc. The coupling is selected taking into account the rated torques TKN and maximum torque T K max. 1.1 Load by rated torque Determination of the actual rated torque TN of the PAN/LN [kW] TN [Nm] = 9550 •  ____________  machine. n [rpm] Taking into account the operating factor S B and the T KN ≥ TN • SB • St temperature factor St, the permissible rated torque TKN of the coupling has to be at least as high as the rated torque TN of the machine.

2. Drives with periodical torsional vibrations. For drives subject to high torsional vibrations, e. g. diesel engines, piston compressors, piston pumps, generators, etc., it is necessary to perform a torsional vibration calculation to ensure a safe operation. If requested, we perform vibration calculation andplease the coupling lection inthe ourtorsional company. For necessary details see seKTR standard 20004.

POLY Torsionally flexible, shear type coupling Coupling description General description:

The POLY coupling is a torsionally flexible, not failsafe coupling for general machinery. It is assembled by axially pluging the hubs into each other and has excellent dampening characteristics. Its unique features are the flexible elastomeric elements that are located in both coupling halves. The POLY advantage – A much greater number of flexible elements and thus a larger effective mass of the elastomer to accept vibration and to dissipate the heat caused by torsional vibrations when compared to similar competitive couplings with elements only in one half. Coupling selection

The coupling selection must be done on the base POLY-NORM ® or ROTEX®. Function/Design

The coupling consists of 2 hubs with fingers that are separated by elastomeric elements which are assembled by axial blind plug-in to each other. Elastomer elements are placed into the slots of both coupling hubs. Torque is transmitted in a compact design. Shaft misalignments, vibrations and shock loads are effectively absorbed by the POLY coupling. The coupling is maintenance-free and used in general machinery, the pump industry and in compressors. The Poly coupling handles torque ranges of up to 14300 Nm and is stocked in 16 different sizes and 3 designs for immediate availability. In addition to our standard coupling models, a variety of flange, drop out lability. center and spacer options are available.

Explosion-proof use

POLY couplings are suitable for the use in drives in hazardous areas. The coupPOLY lings are certified according to EC Standard 94/9/EC (A (ATEX TEX 95) and belong to category 2G/2D, are confirmed and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22. Please read our information in the respective Type Type Examination Certificate and the operating and mounting instructions under www.ktr.com.

Variation of components

The coupling can be adapted to many applications due to the many options that are possible with the building block arrangement. The POLY components of a given model can be mixed and matched with each other to obtain different shaft distances using the same basic component. General information about the elastomer packing
