In particular shaft connections to servo drives provide high demands on play-free and vibration-free torque transmission. The transmission power increases here with increasing speed. Tsubaki extended these requirements in accordance with its range of Elastomer Couplings (Jaw-flex coupling) to a taper-lock variant. This extends the range on 2,5-fold higher shaft speed while maintaining the transmission performance of the existing terminal elastomer couplings.
Especially in machine tools, the choice often falls on the elastomer couplings of the drive specialist, because they allow a high manufacturing precision. The new LN series elastomer couplings have optimum torsional rigidity, excellent damping properties and a simple design for quick installation: The couplings consist of two aluminum hubs, which are connected to the shaft by means of a clamping ring and clamping screw. With the taper-lock coupling, the conical hub is fixed on the shaft via a clamping ring. Higher contact forces and the imbalance-optimized design enable higher speeds.
The elastomeric star located between the two hubs is available in two materials: for applications requiring very good vibration damping and for applications requiring high stiffness and wear resistance. There are six versions of the clamp couplings for shaft diameters from 12 to 42 mm, which transmit nominal torques from 60 to 405 Nm. Depending on the model and elastomer material, the torsional stiffness 2200 to 14.600 Nm / rad and the maximum speed 4800 to 12.000 min-1.
In applications such as robot servo motor control and machine tools, where precision and reliability are crucial, elastomer couplings are already being used successfully today.
