Measuring, printing, coating or packaging – compact coupling systems for various applications

The coupling manufacture is offering four series of these encoder couplings for different requirements.
The series Standard is the choice for all standard encoders and tachos, featuring a balanced design of precision with very low restoring forces to meet exactly the requirements of today’s encoders. It is available with outer diameters ranging from 19 mm to 37 mm and offers a maximum radial misalignment capacity depending on size up to 1 mm, a maximum angular misalignment capacity up to 1,5°. The anodized clamp hubs are balanced for high rpm applications up to 25.000 rpm. A modular construction guarantees all bore combinations ranging from 3 mm up to 20 mm from stock.
The Impuls Plus series is designed for encoders with maximum accuracy. It is predestined for encoders using a graduated disk with increased line counts or with fine measuring signals.
For applications where the coupling has to be integrated into a very tight axial space - as an example where the coupling has to be mounted in a fixed housing - the Compact series is a solution.
The series Industry provides an increased range of outer and bore diameters specially for robust industrial encoders with larger shaft dimensions.


Besides the mentioned precise shaft couplings for encoders the product range of SCHMIDT-KUPPLUNG includes different compact coupling systems for various applications.
The Schmidt-Kupplung is a compact, torsionally-stiff shaft coupling for a large, variable radial shaft offset. The well-balanced system transmits torque without adding side loads to the drive. Schmidt-Kupplung® is ideal in lots of applications such as woodworking machines, roll forming machines, printing machines, packaging machines and paper making machines.
The precise coupling transmits torque under constant angular velocity at all possible offsets and is available with a torque range from 35 Nm to 6.610 Nm.
Semiflex is a torsionally-stiff, precise shaft coupling, which is short in length to fit into small envelopes. Radial shaft misalignment, depending on size up to 6,6 mm, is compensated via pivoting parallel movement of two pairs of coupling links. By design this compensation is free of restoring forces.
They are available with outer diameters ranging from 50 to 300 mm in different hub versions. For a press-fit shaft connection the design engineer can choose between clamp hubs or split-clamp hubs for an easy drop-out installation or for higher torque requirements in a locking-assembly version. The nominal torque capacity ranges from 44 to 7.040 Nm. To ensure an accurate transmission of torque the all-metal coupling offers a high torsional stiffness up to 2.159 kNm/rad. Typical applications are printing machines, packaging machines or machine tools, rotary indexing systems, test units and in machines for material handling.
The axially fixed Loewe GK can be used for torque applications where the coupling has to resist axial motion. Due to the axial stiffness the coupling also ensures the precise transmission of push and pull loads. The coupling combines the technical features of a single universal joint (angular misalignment capacity, axially fixed) and a shaft coupling (radial misalignment capacity). Typical applications are valve triggering, pick-and-place machines, printed circuit board machines, screw jacks and cylinders.
