3 Servolass ouplings For Every Servo System Requirement Today s Servo Motor pplications are more demanding than ever. The precision positioning requirements and high reverse load characteristics of servo motor applications necessitate a coupling design that specifically addresses the needs of these sophisticated systems. ttributes of a Superior Servo Motor coupling Low Inertia High Torsional Stiffness Zero-acklash Misalignment capability Low Reaction Loads Low Inertia is a critical feature of a superior servo coupling. The inertia should be low so that it does not to add significantly to overall inertia of the servo system. The lower the inertia, the less energy required by the motor to move the system, and therefore higher acceleration is possible. Zero-Max Servolass couplings are made from a high strength aluminum alloy, resulting in very low inertia. High Torsional Stiffness is an important quality of any high performance coupling. Low torsional stiffness couplings will reduce system performance and accuracy. The high torsional stiffness characteristic of the Zero-Max Servolass coupling increases the system resonant frequency, exceeding the resonant operating frequency of most equipment. Zero acklash is another key requirement of a high performance servo coupling. coupling may be considered zero backlash and still have a large amount of torsional windup. Zero acklash along with High Torsional Stiffness allows the coupling to maintain the same angular relationship between the input and output shaft without lost motion. The Zero-Max Servolass coupling is a zero backlash, high torsional stiffness coupling that exhibits a very low amount of windup or lost motion. Misalignment apability of a coupling is also important in a motion control system. Usually, the alignment of a well manufactured servo system will be very good. Over time and under high load conditions, this alignment may deteriorate. The Servo-lass coupling will allow for this misalignment while remaining a torsionally stiff and zero backlash connection. Low Reaction Loads on the system s bearings and connected components is not only desirable, it is one of the primary reasons for using a flexible coupling. The Zero-Max Servolass coupling utilizes a design that provides flexibility for inevitable misalignment, therefore minimizing the reaction loads to the servo motor and system bearings. Under misalignment, the Servolass oupling does not sacrifice any of its torque or torsional stiffness capabilities. 3

Keyways are available upon request. Example: S050R (20 mm x /2") Double Flex design Size mm bore without keyway x /2 bore without keyway Note: The hub design of Servolass couplings will provide the necessary clamping force to hold the shaft in a dynamic application without the use of keyways. Keyways are available upon request. Please reference the bore size chart below for more details on bore sizes and torque. The Style of coupling is entirely dependent on the size of the coupling and bore combination selected.
