Couplings
Micromech supplies WITTENSTEIN alpha precision couplings for reliable torque transmission in servo and industrial drive systems. The range includes backlash-free metal bellows couplings, vibration-damping elastomer couplings and torque limiters designed to protect machinery from overload.
WITTENSTEIN alpha precision couplings provide reliable torque transmission between motors, gearboxes and driven equipment. Designed for precision drive systems, the range supports accurate movement while compensating for shaft misalignment, damping vibration or protecting machinery against overload.
The range comprises three main coupling technologies:
Metal bellows couplings provide high torsional rigidity and completely backlash-free torque transmission for precise, dynamic servo applications. They compensate for axial, angular and lateral shaft misalignment while remaining compact, fatigue-resistant and maintenance-free.
Elastomer couplings use replaceable intermediate elements to damp torque peaks and vibration. Different elastomer characteristics allow torsional rigidity and damping performance to be matched to the application.
Torque limiters combine precise torque transmission with a mechanical disengagement mechanism. If the preset torque is exceeded, the coupling disconnects rapidly to protect motors, gearboxes and other machine components from overload damage.
Available models accommodate acceleration torque ratings from 0.1 to 10,000 Nm and selectable bore diameters from 3 to 180 mm, depending on the coupling type and configuration. A choice of radial clamping hubs, axial conical clamping hubs and plug-in connections supports straightforward installation across a wide range of drive arrangements.
Typical applications include:
- Servo and stepper motor systems
- Industrial robots
- Machine tools
- Packaging machinery
- Linear modules and spindle drives
- Belt-driven systems
- Material-handling equipment
- Printing and converting machinery
- Inspection and test equipment
- General industrial automation
