general information 2
technical features
The flexible claw coupling N (ELKU-N) is a positive-locking, tor-sionally, flexible coupling which allows radial, axial and angular displacement between the driving and the driven shafts. It is slip proof. Torque is transmitted through the flexible buffer set into the po-ckets of the flexible buffer section which is distributed evenly over the circumference of the coupling. The claws on the guide ring or claw section grip into the buffer gaps. The buffers are subjected to compression from which results slight wear and high loading capacity.
The high damping of the coupling protects the drive from excessive dynamic overloading. The progressively rising spring charcteristic al-lows a rapid reduction in energy oscillations and limits their amplitude. Perfect operation can be guaranteed at a working temperature of -30 °C to +80 °C. The standard design is in grey cast iron EN-GJL-250-DIN EN 1561.

calculation example:
Coupling ELKU-N searched for steady drive.
Driving machine: AC motor type 315 L - 200 kW -1 485 rpm, shaft diameter 80 mm
quantity Z = 40 per hour - ambient temperature ϑ = +40 °C starting torque T
AS ≈ 2T
AN = 2 574 Nm
Working machine: centrifugal pump with a relatively low mass inertia average load torque T
LN= 1 150 Nm
impact of the rated torque T
KN ≥ T
LN • S
ϑ= 1 150 Nm • 1,2 = 1 380 Nm
according to the rated torque is the ELKU-N coupling size 250 in question for T
KN= 2 500 Nm and T
Kmax= 5 000 Nm.
Check for TKmax factors:
starting factor: SZ= 1
temperature factor: Sϑ= 1,2
impact factor: SA= 1,5
TKmax

• SZ • S
ϑ • S
A = 2574 Nm • 1 • 1,2 • 1,5 = 4 633 Nm
With this example, a coupling selection is simplified by Bill passa-ge represented. It is recommended that a coupling selection by the trained personnel of KWD leave to carry.

Installation and operating conditions
The arrangement of the coupling parts to be connected to theShaft ends is desired.The given permitted misalignment values provide generalValues under the following conditions is:
• Load up to the rated torque• Operating speed n = 1 500 rpm (for n <1 500 min-1 is the maximum speed)• ambient temperature of +30 °C.• Maximum values in radial or angular misalignment
If both shifts at the same time, the values may onlybe used proportionately. In this case, please consultwith the manufacturer.
balancing condition
In general, the elastic claw couplings in unbalanced state deli-vered.After the user‘s requirements, they can dynamically the quality Q 6.3 (ISO Recommendation 1940) or static delivered balanced.
Size selection in accordance with DIN 740 Part 2
Size selection in accordance with DIN 740 Part 2 The design of the coupling is the laws of physics.
It is recommended that a coupling selection the trained personnel of KWD perform to leave.
