The special design of the SERVOPLUS® coupling allows the removal of the coupling or the bellows replacement without pulling apart the drive. Maintenance andwear. » pull apart the drive and remove the coupling. SERVOPLUS® couplings are wear andmaintenance free. Dismounting. Bearing load. SERVOPLUS® couplings are delivered with finished bore and ready for installation. » carefully clean the contact surfaces. » position the coupling on the shafts ends and carefully tighten the radial clamping screws to the indicated torque TA. » loosen radial screws. » loosen the socket screws. » loosen the radial clamping screws. roughness R 16μ tmax Working temperature. Due to flexibility in handling axial, angular and radial misalignment, SERVOPLUS® couplings allow reduced bearing load which reduces maintenance cost. Peak torque. SERVOPLUS® couplings allow for short periods a peak torque equal to the 1,5 time the nominal torque. The hub shaft connection must be correctly dimensioned. SERVOPLUS® couplings may be used up to 300° Cwithout limitation. » remove the clamping hubs. Shaft requirements for a safe torque transmission are: Note. It is recommended to pay careful attention during the mounting and dismounting operation. Damaging the bellows may render coupling unusable. tolerance h6 » move the clamping hubs on the shafts. Safety norms. All rotating parts must be protected against any possibility of contact with people. Protection must be designed so that even in case of coupling failure, personnel and equipment is protected. SERVOPLUS® couplings are designed for an infinite number of cycles when themaximummisalignment values and peak torque are respected. Technical features. Long lasting.
