Spiders – our innovation T-PUR®

KTR has developed a new standard material for its spiders. The improved polyurethane

material T-PUR® is resistant to signiﬁcantly higher temperatures and has a considerably

longer service life than the previous polyurethane material. From the visual point of view

we have characterized the material T-PUR® by the colours orange (92 Shore-A), purple

(98 Shore-A) and pale green (64 Shore-D). The previous spiders made of polyurethane

in yellow, red and natural white with green ends will still be available.

Up to size ROTEX® 180 inclusive single-parted spiders are used as a standard. Optionally

the DZ tooth elements continiue to be available for ROTEX® couplings sizes 100-180.

Explosion-proof use

ROTEX® couplings are suitable for power transmission in drives in hazardous areas. The

couplings are certiﬁed and conﬁrmed according to EC standard 94/9/EC (ATEX 95) as

units of category 2G/2D and thus suitable for the use in hazardous areas of zone 1, 2, 21

and 22. Please read through our information included in the respective Type Examination

Certiﬁcate and the operating and mounting instructions at www.ktr.com.

In addition to the ATEX marking an inspection certiﬁcate by DNV, Bureau Veritas or ABS

can be ordered for ROTEX® couplings.

Performance

In contrast to other ﬂexible couplings, the intermediate members of which are subject to

bending stress and are therefore prone to earlier wear, the ﬂexible teeth of ROTEX® cou-

plings are subject to pressure only. This gives the additional advantage of the individual

teeth being able to accept considerably higher loads. The elastomer parts show deforma-

tion with load and excessive speeds. Sufﬁcient space for expansion should be ensured

(see drawing – deformation with load).

The maximum torsion angle with ROTEX® couplings of any size amounts to 5°. They can

be ﬁtted both horizontally and vertically.

General description

ROTEX® couplings are torsionally ﬂexible and designed for positive torque transmission.

They are fail-safe. Operational vibrations and shocks are efﬁciently dampened and re-

duced. The two congruent coupling halves with concave claws on the inside are periphally

offset in relation to one another by half a pitch. In addition, they are designed in such a

way as to enable an involute spider to be located between them.

The teeth of the spider are crowned to avoid edge pressure if the shafts are misaligned.

ROTEX® couplings are capable of compensating for axial, radial and angular

displacements of the shafts to be connected.

ROTEX®couplings are characterized by small dimensions, low weight and low mass

moments of inertia yet transmit high torques. Running quality and service life of the coupling

are improved by accurate all-over machining.

Their application is ideal for transmitting torque while damping torsional

vibrations and absorbing shocks produced by the uneven operation of certain

prime movers.

The ROTEX® coupling is selected in accordance with DIN 740 part 2. The coupling has to be dimensioned in a way that the permissible coupling

load is not exceeded in any operating condition. For this purpose the actual loads have to be compared to the permissible parameters of the

coupling. The torques TKN/TKmax mentioned refer to the spider. The shaft-hub-connection has to be investigated by the customer.

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 TK max.

1.1 Load produced by rated torque

Taking into consideration the ambi-

ent temperature, the permissible rated

torque TKN of the coupling has to cor-

respond at least to the rated torque

TN.of the machine.

1.2 Load produced by torque shocks

The permissible maximum torque of the

coupling has to correspond at least to

the total of peak torque TS and the

rated torque TN of the machine, taking

into account the shock frequency Z and

the ambient temperature. This applies

in case if the rated torque TN of the

machine is at the same time subject to

shocks. Knowing the mass distribution, shock direction and shock mode,

the peak torque TS can be calculated. For drives with

A. C.-motors with high masses on the load side we

would recommend to calculate the peak driving torque with the

help of our simulation programme.

Coupling selection

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 the torsional vibration calculation and the

coupling selection in our company. For necessary details please

see KTR standard 20004.

2.1 Load produced by rated torque

Taking into account the ambi-

ent temperature, the permissible

rated torque TKN of the coupling has to correspond at

least to the rated torque TN of the machine.

2.2 Passing through the resonance

range

Taking into account the temperature,

the peak torque TS arising when the resonance range is run through

must not exceed the maximum torque TKmax of the coupling.

2.3 Load produced by vibratory torque shocks

Taking into account the ambient

temperature, the permissible vibra-

tory torque TKW of the coupling

must not be exceeded by the high-

est periodical vibratory torque TW with operating speed. For

higher operating frequencies f > 10, the heat produced by

damping in the elastomer part is considered as damping power

PW. For higher operating frequencies f > 10, the heat produced by

damping in the elastomer part is considered as damping power

The above-mentioned ﬁgures of displacement of ﬂexible ROTEX® couplings are standard values taking into account the load of the coupling

up to the rated torque TKN and an operating speed n = 1500 rpm along with an ambient temperature of + 30° C.

The displacement ﬁgures may only be used individually - if they arise simultaneously, they must be used proportionately. Care should be

taken to maintain the distance dimension E accurately in order to allow for axial clearance of the coupling while in operation. Detailed mount-

ing instructions are shown on our homepage (www.ktr.com).

Split hub made of cast iron. Frictionally engaged, backlash-

free shaft-hub-connection-. Transmittable torques depending

on bore diameter (For ATEX category 3 only)

Split hub made of cast iron. Positive locking power transmis-

sion with additional frictionally engaged condition. The

frictionally engaged condition prevents or reduces reverse

Hub designs

Due to the numerous applications of ROTEX® for many different applications and mounting situa-

tions, 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.

Cylindrical bores and spline bores

Spline clamping hubs are often adapted to the shafts of hydraulic pumps/hydraulic motors. Please ask us about the corresponding hub length of the spline code!

1) For clamping hubs only, for plug-in hubs use code PT or PQ.

2) Proﬁle correction different from DIN

The transmittable torques of the clamping connection consider the max. clearance with shaft ﬁt k6/bore H7, from Ø55 G7/m6. With a higher clearance the torque is reduced. For the stiffness
