Valve electric device to prevent overload of the right choice and is very much related and should pay attention to. In consideration of economic aspects limiting torques is a continuous challenge when developing Torque Limiters as an overload protection. The new generation of the backlashfree Torque Limiters. The new generation of the backlashfree Torque Limiters has been designed for being used in powertransmission and servo applications. Important requirements such as being backlashfree, short reaction times and long service life have been further optimized. The constructive benefit is ensured through fast availability of applications after a crash. For limited installations The further development and optimization of the already well established backlashfree Torque Limiter series SK has brought about an appropriate design for each application. The transmittable torques can be accurate defined and set. Even in regard to restricted installation space now, the couplings represent the latest stateoftheart. Areas of applications of the Torque Limiters ranging from to 2,800 Nm can be found in any type of mechanical dynamic drives are being continously improved by the use of preset Torque Limiters. When the overload occurs the Torque Limiters disengage in milli seconds. The movement of the Actuation ring can be sensed, and used to control and shut down the machine. Immediate availabillity of the machine after reengagement of the Torque Limiter can be assured. Increased economic efficiency Optimized disc springs and materials adapted to the use of the coupling allow for the pact and reliable design, better performance and wer mass. Also a long service life and maintenance free operation are importtant consierations when selecting couplings. Smaller couplings bined with a higher torque density additionally result in a cost advantage due to smaller dimensioning. On average the size of the Torque Limiter has been reduced by approx. 1/3 pared to other available products. This results in a reduced separation of masses in case of a crash due to the reduced weight and a smaller technical diameter. When paring the facts, it is clear that R + W develops and delivers the most pact Torque Limiters available period. A great variety The advantage of ball detent design Torque Limiters is the separation of the drive and the driven elements in milliseconds in case of an overload. Easy handling reliability are further advantages. Machine designs with little installation space or difficult to access areas do however often require special solutions. The R+ W range facilitates the easy modification by means of a modular concept. The hub type that is appropriate for the application is selected and integrated for the ideal design. The pressfit principle that has been developed by R+W uses the axial spring force of the metal bellows to pretension a t
