Couplings
Couplings
A coupling is a device used to connect two shafts together at their ends to transfer power. Their primary purpose is joining two pieces of rotating equipment together while permitting some degree of misalignment, end movement, or both.

Couplings are most commonly used to transfer power from a motor to a pump, connect shafts of two machines manufactured separately, provide mechanical flexibility, prevent shock and vibrations from transferring from one piece of equipment to another, and potentially slip when torque overload occurs.

They typically feature two rigid parts that fit around the end of two shafts to form a sleeve. A hub sits between the teeth to provide the buffer between each coupling half. Flexible couplings provide similar results with a one-piece aluminum body design to shift under differential torque loads.

Rotex Series Image
  • Axial Plug In
  • Flexible
  • Fail Safe
KTR Rotex Couplings are a three part, axial plug-in coupling that are torsionally flexible and designed for positive torque transmission. 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 couplings are capable of compensating for axial, radial and angular displacements of the shafts to be connected.

DATAFLEX Series Image
The recently developed Dataflex 16 extends the existing range of contactless torque measuring shafts and is available for measuring torque ranges of 89 [lb-in], 266 [lb-in] and 443 [lb-in]. The torque is measured using well-approved technology of wire strain gauges combined with the latest electronic components.

Supplementary to torque measuring the size 16 has a speed encoder providing two offset impulse with a resolution of 360 pulses per revolution. The Dataflex torque measuring shafts sizes 22 to 140 measure the torques without contact and free from wear. Their secret is a patented measuring method acquiring the twisting of the torsion shaft by measuring the quantity of light. For that purpose the light is directed through two disks the transparency of which is amended proportionally to the torque. The overall electronics are situated in a stationary housing to make sure that no signals have to be transmitted by the rotating shaft and the torque is available accurately with a high band width of 16kHz. This can measure and analyze highly dynamic processes accurately. The analog output values are available both as a voltage signal from 0-10V and as a current signal from 4 - 20 mA.
