ARCUSAFLEX ® Nominal torques from 210 Nm to 72 000 Nm ARCUSAFLEX ® Advantages and uses Key features and benefits of the ARCUSAFLEX ®-coupling: ➜ ➜ The selection of different shore hardnesses Very high torsional elasticity with a linear torsional deflection enablesoptimum torsional vibration tuning and the shifting of resonances into non-critical operating ranges ➜ System reliability and durability High torsional vibration and shock load damping capability Adaptability to operating conditions, various vulcanizates for ambient temperatures up to 130 °C Elastomer teeth may slip in the event of...

Coupling Information ARCUSAFLEX ® Standard Types Flange coupling with taper bush The ARCUSAFLEX® flange coupling type AC-T…F2 is equipped with a taper bush for shaft mounting. The rubber element is vulcanized directly to the hub body of the taper bush. After completion of the assembly, a shrink-fit-like connection, free from backlash is Taper bush established between the coupling hub with rubber element and the shaft. Thanks to the use of commercially available taper bushes with a number of different bore dimensions, the need for finishing the bore and keyway of the coupling hub is omitted...

Coupling Information Selection of the coupling size The coupling size, for use in combustion engines, is designed and selected with a view to torsional vibration. For preliminary selection using the engine torque TAN a general safety factor of S = 1.3 - 1.5 should be applied for ARCUSAFLEX® couplings with flexible disc elements of natural/synthetic caoutchouc. In selecting the coupling size the following should be satisfied: The nominal torque of the coupling TKN must be taken into account at every temperature and operating load of the coupling while observing the service factors S (e.g:...
