2 The CONTROLFLEX B A S I C APPLICATION The Controlflex is a compact and precise shaft coupling with excellent kinematical properties which makes it the ideal coupling for shaft encoders. All types of shaft misalignments are accom- modated via the proven Controlflex design. CONTROLFLEX I N F O R M A T I O N Easy Installation The clamp hubs install easily on to the shaft. Furthermore, the modular design of the Controlflex allows each hub to be independently mounted on different shafts and then to be connected by the middle element. BASIC INFORMATION TECHNICAL FEATURES and BENEFITS Constant Angular Velocity The patented middle element is torsionally stiff and radially flexible. It is specifically designed to accoodate shaft misalignment while at the same time transmitting torque at constant angular velocity. No Side Loads The Controlflex compensates for shaft misalignment inducing very low side loads, increasing the operating life of other machine components. Compact Design The Controlflex requires remarkably little axial space. In spite of that the Controlflex has a large misalignment capacity. Other types of encoder couplings can only provide further misalignment capacity by extending the length of the coupling. Modular Construction The modular construction of the Controlflex with two clamp hubs and either one or two middle elements makes it possible to realize all possible bore combinations from stock. This keeps costs down and delivery times short. Robust The Controlflex is not overly sensitive to brief periods of excess strain during handling, installation and operation. Electrically Insulating The middle element is molded from Delrin yielding long life, vibration dampening, and electrical 4 insulation (ca. 101 W cm). Absorbs Vibration Large Misalignment Capacity Misalignment compensation is a prime reason for using a shaft coupling. The patented Controlflex design provides large misalignment capacity with good torsional stiffness and low side loads. 2

Many factors influence a coupling's operating life. The influence of torque, RPM and misalignment are discussed in the following. Torque The maximum torque T should not be exceeded. KN The design torque is calculated as follows: RPM T Service factor N The torque carrying capacity decreases as radial misalignment and speed increase. For complex applications consult the factory. Due to the design of the coupling, higher speeds lead to higher stress on the coupling. The maximum speed should not be exceeded. Radial misalignment At no time should the radial misalignment K r be exceeded. If the catalog values do not fit your application, consult the factory. We can design a coupling that will.

ADDITIONAL INFORMATION Axial misalignment The axial space available for the coupling must be at least the coupling length L. The capacity to compensate for thermal expansion and assembly tolerances is given by the value Ka An opera- ting length close to L is beneficial. The coupling is axially free. This can be used when an axial assembly is advantageous. Angular misalignment Angular misalignment has an effect on the operating life of the coupling. The angular misalignment must always remain within the values given. 7
