Misalignment values

Typical applications Normal drives Normal drives, also with resonance speed possibility Normal drives with high High performance with performance small torsional angle

Service factor K1 Driven machine / Example Prime motor Uniform operation with small masses to be accelerated Hydraulic and centrifugal pump, light generators, ventilators, transport systems Further factors SOFTEX® couplings Coupling selection* "The largest possible torque TN should be used as a basis. The catalogue torque TKN has to be multiplied with all safety factors. For drives with dangerous torsional vibrations, the critical speed must be considered. 163

Product description • Under initial tension no backlash shaft connection • Triple axially pluggable version • Simple blind mounting, no time-consuming screwings • Small structural dimensions - low flywheel effects • Maintenance free, simple optical test • Different elastomer hardnesses of the spiders • Available for all common shaft dimensions • Finish bores with ISO standard H7, (clamping hub F7), keyway from 0 6 acc. to DIN 6885 • Hub materials: aluminium up to size 38 / 45, steel for larger sizes Type 1.0 with keyway and fixing screw • Positive transmission • Permissible torque depending on...

• Zero backlash shaft connection under high friction torque • For Servo motor applications such as main spindle drives of tooling machines and heavy load of presses • No imbalances of keyways or slotted clamping elements • Smooth running with good stability even at 40 m/s peripheral speed • Also suitable for ATEX explosion protection applications (when considering the selection in accordance with the influence of high friction torques) • Easy assembly by internal clamping screws • Materials: Hub = aluminium / clamping ring = steel, both also available in steel S355J2 • High precision, zero backlash...

In case of higher speeds a dynamic balancing of the hubs is required. The length dimension L is increased by the indicated A ka values. The specified misalignment values are general guide values. In case of current angular and radial misalignment the indicated values can only be utilised proportion atel y. In case of a temperature increase the permissible torques and the max. permissible radial and angular misalignment values must be multiplied by the temperature factor St. Complete coupling type 1.0 with medium bore on both sides
