Description
Flender N-Bipex Size 48 Coupling Element – Cam Ring Insert
Cam ring of polyurethane 92 ShoreA (standard)
Includes 1 x Cam Ring Insert, Size 48
Benefits:
- N-BIPEX (Nbipex) couplings are suitable for horizontal, vertical and freely selectable mounting positions. They are able to absorb axial, radial and angular misalignment.
- N-BIPEX couplings consist of two identical hub parts which can be arranged as required on the shaft extensions to be connected. N-BIPEX couplings transmit the torque positively and are thus fail-safe. The curved design of the cast cams ensures that the N-BIPEX couplings have a perfect pressure distribution and this increases the elastomer lifetime.
- The flexible cam rings responsible for torque transmission and misalignment compensation are available in different Shore hardnesses. As a result of the good damping capability and by selecting the suitable stiffness, torque shock loads can thus be absorbed and the torsional vibration behavior of the drive can be positively influenced. Different cam ring versions and ready-to-install hub parts are available.
Application:
- The N-BIPEX coupling is available as a catalog standard in 10 sizes with rated torques of between 12 Nm and 4650 Nm and is made of high-grade spheroidal graphite cast iron.
- The extremely high-performance cam ring materials are available in three different Shore hardnesses with the following colours:
92 ShoreA – red
95 ShoreA – green
64 ShoreD – blue
- An additional size marking has been provided on the outer surface of the cam ring to be able to determine the size of the N-BIPEX even when it is in the assembled state without having to use any additional aids.
- The coupling is suitable for use at ambient temperatures between -50 °C and +100 °C without any restrictions on the rated torque as a result of temperature factors.
Function:
- The torque is transmitted to the hub at the drive end via the shaft-hub connection, which is mostly designed as a keyway connection, and is transmitted to the hub on the output side via the cam ring. This hub then further transmits the torque to the driven machine or a gear unit placed in between.
- The special cam ring design helps to keep the compression-loaded cam ring elements in their defined position under all operating conditions and to keep them evenly loaded. This results in a long lifetime of the flexible elements. A long lifetime is also guaranteed by the hub parts which ensure maximum operational reliability even under harsh operating conditions.
Design and configurations:
- The N-BIPEX coupling of type BWN comprises two identical hub parts connected by a cam ring of elastomer material.
- The hubs are connected to the respective shafts via finished bores with parallel keyway connection or Taper clamping bushes. N-BIPEX couplings are positive-locking and torsionally flexible thanks to the thermoplastic polyurethane cam ring.
Coupling materials:
Hubs: Steel
Cam ring:
• TPU 92 ShoreA -50 °C to +100 °C/120 °C without /with restrictions
• TPU 95 ShoreA -50 °C to +100 °C/120 °C without /with restrictions
• TPU 64 ShoreD -50 °C to +100 °C/120 °C without /with restrictions
The coupling comprises the following:
• Cam ring
• 2 hub parts with identical cams
The hub parts are designed with a bore and keyway to DIN 6885-1 or with a taper bore for mounting a Taper clamping
bush.
Fitting the clamping bush connects the hub firmly to the machine shaft.
In the case of part 4 the Taper clamping bush is inserted from the machine housing side. If there is insufficient space, the Taper clamping bush cannot be fitted from this side. Besides space for fitting the Taper clamping bush, space for the fitting tool (offset screwdriver) must be taken into consideration. In the case of part 3, the Taper clamping bush is screwed in from the shaft end face side. The hub must be fitted before the machines to be connected are pushed together.
Original FLENDER® elastomers ensure the optimal operation of your system.
