Product catalog summary
Company Overview
Schmidt-Kupplung GmbH has over 50 years of experience in providing compact coupling systems for machine manufacturers. They offer a range of products known for their technical functionality, including both standard and custom solutions tailored to specific industries and applications.
Product Features
The Semiflex coupling is a torsionally stiff, precision coupling that compensates for axial, angular, and high radial displacements without restoring forces. It features a unique system of two pairs of 90°-offset parallel links to maintain angle synchronization of connected shafts.
Technical Specifications
- Synchronization is maintained even with high displacement.
- No restoring forces due to needle bearings in coupling links.
- High offset capacity with a compact design.
- Made from high-quality steel and aluminum, offering high torsional stiffness and torque transmission.
- Maintenance-free with lifetime lubrication.
Product Line-Up
- Standard F: Combines performance and compact design, available for nominal torques up to 14,500 Nm.
- Compact Plus C: Shorter length for confined spaces, available for nominal torques up to 7,040 Nm.
- Dynamic D: Lightweight aluminum for high angular accelerations, available for nominal torques up to 180 Nm.
Hub Versions
Various hub designs are available, including clamp hubs, split clamp hubs, and locking assemblies, allowing for customization based on specific requirements.
Selection and Installation
The selection of Semiflex couplings is based on performance parameters such as torque, speed, and displacement. Detailed selection sequences and installation instructions are provided to ensure optimal performance.
Applications
Semiflex couplings are suitable for various industries, including paper machines, handling technology, vacuum coating systems, and machine tools, offering offset compensation without restoring forces even in narrow gaps.
Environmental Considerations
Semiflex units are designed for normal ambient conditions and are lubricated for life. They can operate at temperatures up to +120°C, with additional options available for higher temperatures or specific environmental conditions.
Specifications and Procedures
The document outlines the installation and application of various coupling solutions by SCHMIDT-KUPPLUNG. It details hub forms 5, 6, and 7, emphasizing the importance of using a torque wrench to tighten flange fastening screws to client-specified torque. For hub forms 6 and 7, it recommends axial support to prevent axial compressive forces during assembly and suggests radial mounting for applications where shafts cannot be moved axially.
Semiflex Coupling Solutions
Semiflex couplings offer overload protection and high displacement compensation. They are suitable for applications with additional axial forces and special ambient conditions, such as those requiring stainless steel or tailored surface coatings. Application-specific hub designs are available for rapid changes or accommodating large shaft diameters.
Special Structural Lengths and Applications
Custom lengths and designs are available for specific installation spaces, including extremely small conditions and quick plug-blind assembly. Semiflex couplings are used in various industries, including packaging machines, machine tools, conveyor technology, and coating systems.
Industry Applications
The document highlights the use of Semiflex couplings in paper machines for optimal fibre orientation, in conveyor technology for modular systems, in vacuum coating systems for precise thin-film processes, and in machine tools for precise gear manufacturing. These applications demonstrate the versatility and adaptability of Semiflex couplings in different industrial settings.

Offset compensation free of restoring forces even in the narrowest gaps The Semiflex coupling is a torsionally stiff and restoring-force-free precision coupling. In addition to the compensation of axial and angular displacements, it provides high radial displacement capacity together with compact design. The displacement compensation takes place without any restoring forces and via the unique system of two pairs of 90°-offset parallel links. The angle synchronisation of the connected shafts is retained at all times. www.schmidt-kupplung.com

| Controlflex | Semiflex | Schmidt-Kupplung | Servoflex | Loewe GK | Omniflex Technique Synchronisation, even with high displacement The Semiflex transmits torque via two pairs of 90°-offset parallel links. They connect the input and output disc with the centre disc. In case of aligning shafts, all three di- scs are also in an aligned position. In case of occurring radial displacement, the links move parallely as one group and let the centre disc radially divert by a corresponding extent. Since each pair of the coupling links always remains in- ternally parallel to each other, the connected shafts...

| Controlflex | Semiflex | Schmidt-Kupplung | Servoflex | Loewe GK | Omniflex High misalignement capacity in compact design Extremely space-saving design Compact without limitations A design advantage of Semiflex are its very compact dimensions. Here, there is no dependence between the amount of radial offset values and the overall length. For couplings which compensate for offset with bending elastic behaviour, the permissible offset significantly decreases with shorter designs. Semiflex thus gives the user a space-saving design with no restrictions on the function values. With extremely critical...

| Controlflex | Semiflex | Schmidt-Kupplung | Servoflex | Loewe GK | Omniflex Selection sequence The selection of the Semiflex is determined by the various performance parameters. These include torque, speed and occurring displacement. The influences of these parameters are described below: Selection according to torque Calculation of the design torque TD: Please multiply your continuous torque TA by the required performance factor F and the required service factor to get the design torque. TD = TA x F x K Please choose your operating speed of your application combined with the required nominal...
