Coupling description
General description
®
ROTEX components via curved jaw hubs and elastomeric elements commonly known as spiders. The combination of these components provides dampening and accommodation for misalignments. This product is available in a variety of metals, elastomers and mounting configurations to meet your specific needs.
couplings are designed to transmit torque between drive and driven

ROTEX
Function and Design
®
ROTEX
– couplings suitable for horizontal or vertical applications are constructed from a variety of materials and geometries providing a torsionally flexible platform optimizing the balance between inertia, coupling performance and application requirements. The machined concaved jaws provide a pocket for the crowned spider legs, allowing the hubs to articulate freely while accommodating misalignment, minimizing restoring forces, dampening shock and vibration while providing failsafe torque transmission. The symmetrical relationship of the hubs allows for a variety of accessories to accommodate different shaft distances. Together with the curved jaw, the crowned design reduces edge loading of the ROTEX
®
spider while compensating for misalignment and providing system dampening. The unique geometry of the coupling, in addition to a variety of spider materials and durometers, contribute to the dampening characteristics of the system. In contrast to other flexible couplings with elastomeric elements in shear, ROTEX
®
coupling spiders are in compression, defining the torque of the coupling. This design characteristic results in a maximum torsional angle of 5° and minimizes spider expansion due to deformation at excessive speed/loads as illustrated. Interlocking curved jaws with a variety of standard clamping options accommodates shafts up to 7.875 inches and a maximum nominal torque of 309,750 lb-in while still accommodating blind assembly. As defined by the spider, ROTEX couplings are suitable for moderate industrial temperature ranges. Together these features reduce the maintenance required during the life-cycle of the coupling.
Explosion-proof use
®
ROTEX
couplings are suitable for power transmission in hazardous areas. The couplings are certified and conform to EC standard 94/9/EC (ATEX 95) as units of category 2G/2D and are suitable for use in hazardous areas of zone 1, 2, 21 and 22. Please read through our information included in our Type Examination Certificate and the operating and installation instructions at www.ktr.com.

Spiders - our innovation T-PUR® KTR has developed a new standard material for our ROTEX couplings. The improved polyurethane material, T-PUR® is able to accommodate higher application temperatures for an even longer life than our previous polyurethane. In order to see the improvement, our T-PUR® material are identified in color as; orange (92 Shore-A), purple (98 Shore-A) and pale green (64 shore-D). The previous colors yellow, red and natural white with green ends are still available for a limited time. As in the past ROTEX coupling sizes 100 to 180 utilize our DZ segments as standard, with a single element available as an option.

Torsionally flexible coupling
Coupling selection
The ROTEX®coupling is selected in accordance with DIN 740 part 2. The coupling must be dimensioned in a way that the permissible coupling load is not exceeded in any operating condition. For this purpose, the actual loads must be compared to the permissible parameters of the coupling.
1 Drives without periodical torsional vibrations
e. g. centrifugal pumps, fans, screw compressors, etc. The coupling is selected taking into account the rated torques T and maximum torque T

1.2 Load produced by
torque shocks
The permissible maximum torque of the coupling must correspond with the total of peak torque T the rated torque TNof the

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 safe operation. If requested, we will perform the torsional vibration calculation and the coupling selection for you. For details please contact KTR Engineering.

The above misalignment figures for ROTEX®couplings are standard values, taking into account the load of the coupling up to the rated torque TKNand an operating speed n = 1,800 RPM along with an ambient temperature of + 86° F. For other operating parameters, please ask for KTR-Norm 20240 on misalignments for ROTEX
®
. The maximum angular and parallel misalignments must not be used concurrently. For example; 70% of the maximum parallel value allows 30% of the maximum angular value. Also, care should be taken to accurately maintain the distance dimension “E”, allowing for axial clearance of the coupling while in operation. In case of an axial thrust, the dimension "L" must be taken as a minimum dimension in order to keep the spider free from pressure against the face. Detailed installation instructions are available at www.ktr.com.

Torsionally flexible coupling
Hub designs
Due to the numerous applications of ROTEX®for many different mounting situations, this coupling system is available with various hub designs. These designs mainly differ in that they offer either positive or frictionally engaged connections, but mounting situations like, for example, gear shafts with integrated transmission cams or similar applications are covered, too.
®
ROTEX
Design 1.0 hub with keyway and fixing screw
Positive locking power transmission, permissible torque
epending on the permissible surface pressure. Not suitable
d for backlash-free power transmission with heavily reversing operation.
Design 1.1 hub without keyway with fixing
Non-positive torque transmission for crimped and glued
onnections (no ATEX release).
c
Design 1.3 hub with spline bore
®
Design 4.2 with CLAMPEX
rictionally engaged, backlash-free shaft-hub-
F connection for the transmission of average torques.
Design 4.1 with CLAMPEX
esign 4.3 with CLAMPEX
D
Frictionally engaged, backlash-freeshaft-hub connection for the transmission of high torques.
Design 7.5 shell clamping hub without feather key for a double-cardanic connection
Frictionally engaged backlash-free shaft-hub-connection for radial assembly of coupling. Transmittable torques depending on bore diameter. (for ATEX category 3 only).
Design 7.6 shell clamping hub with feather key
for a double-cardanic connection
Positive locking power transmission with additional frictionally engaged condition for radial assembly of coupling. The frictionally engaged condition prevents or reduces reverse backlash, respectively. Surface pressure of the feather key connection is prevented.

Design 2.1 clamping hub, single slotted, with keyway
Positive locking power transmission with additional frictionally engaged condition. The frictionally engaged
ondition prevents or reduces reverse backlash,respectively.
c Surface pressure of thefeather key connection is prevented.
esign 2.3 clamping hub with spline bore (page 33)
D
Design 6.0 clamping ring hub
(see ROTEX
Integrated frictionally engaged shaft-hub-connection for the
ransmission of higher torques. Screwing on elastomer side.
t For details about torque and dimensions see page 33. Suitable for high speeds.
Design 6.5 clamping ringhub
(see Rotex GS series)
Design like 6.0, except for clamping screws externally. As an example for radial assembly of intermediate pipe (special design).
Design 7.8 shell clamping hub without feather key
Frictionally engaged, backlash-free shaft-hub-connection for radial assembly of coupling. Transmittable torques depend on the bore diameter (for ATEX category 3 only).
Design 7.9 shell clamping hub with feather key
Positive locking power transmission with additional backlash for radial assembly of coupling. The frictionally engaged condition prevents or reduces reverse backlash, respectively. Surface pressure of the feather key connection is prevented.
