ROTEX® Torsionally ﬂexible coupling

Description of coupling

ROTEX 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.

General description

ROTEX They are fail-safe. Operational vibrations and shocks are efﬁciently dampened and reduced. 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 displacements of the shafts to be connected.

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

couplings are torsionally ﬂexible and designed for positive torque transmission.

couplings are capable of compensating for axial, radial and angular

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

couplings 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 deformation 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.

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 the DZ tooth elements continiue to be available for ROTEX

180 inclusive single-parted spiders are used as a standard. Optionally

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.

ROTEX® Torsionally ﬂexible coupling

Coupling selection

The ROTEX 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/T

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

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 T

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.

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.

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.
