NPX Taper Bored Coupling Hub 160 Part 1 (2517)
• Designed to industry standard
• Available with three part flanges, thus allowing the segments to be changed without disturbing either the driving or driven shaft
• High levels of torsional flexibility
• High speed capability
• Suits IEC electric motor applications
• Taper bore and pilot bore flanges
2LC0100-7AA (Flender N-Eupex Basic Code)
Challenge NPX couplings are a failsafe male/female coupling solution. A key advantage of the NPX arrangement is the availability of a two-part male hub. This hub can be dis-assembled, allowing the elastic elements to be replaced without having to move the shafts or lose the couplings positioning on the shaft. As the elements are enclosed and therefore not visible without dismantling the coupling, Challenge provide a free wear gauge with every coupling, allowing element wear to be easily monitored on the outside of the housing.
The NPX range of couplings can compensate for shaft misalignment while also offering vibrational dampening. They are available to suit shaft sizes up to 100mm, with maximum torque ratings ranging from 57Nm up to 8400Nm and a maximum speed of 5000 rev/min. Hubs will be supplied with a pilot bore (finished machined upon request) or with a taper bore to suit our range of taper bushes.
Multiple Proven Solutions - Shaft Couplings
Challenge stock 7 proven shaft coupling methods which offer a range of benefits such as accommodating high torque loadings, shock loading, shaft misalignment in different planes, large shaft diameters and high speeds, with the HRC range are even able to offer fail safe operation. All of our shaft couplings are designed to be easy to fit and remove along with offering a long service life and competitive pricing.
The main choice for multiple planes of alignment between two shafts with the ability to transmit up to 14675Nm of torque. The load carrying cords within the coupling tyre are wound in both directions, offering zero backlash for reversing duties. Visual inspection of the tyre condition, no lubrication requirements, fire resistance/anti static tyre options and no requirements to move the shafts when a tyre needs replacing simplify maintenance and safety. The tyre couplings also offer superior shock absorption and vibration damping making it the first choice for heavy duty/high vibration applications such as crushers and mixers.
Jaw type couplings with an elastomer insert are available in a wide range of variations and configurations. The general layout for these couplings is a hub with teeth which interlock between elastomer lobes. The elastomer lobes act to dampen vibration and accommodate small amounts of mis-alignment. The extended tooth design offers fail safe operation due to the teeth interlocking should the insert fail, although this can damage the teeth. Both straight and curved tooth coupling types are available, although the zero-backlash curved tooth is more common.
Chain couplings offer a highest torque solution but cannot accommodate large shaft misalignment. They often come as a sealed unit within a casing filled with grease as this helps with its operation and increases the working life of the coupling. The coupling consists of 2 simplex sprockets which are joined by a necklace of corresponding duplex power transmission chain.
